Weekly Recap: APT Campaigns, Browser Hijacks, AI Malware, Cloud Breaches and Critical CVEs
Cyber threats don't show up one at a time anymore. They're layered, planned, and often stay hidden until it's too late.
For cybersecurity teams, the key isn't just reacting to alerts—it's spotting early signs of trouble before they become real threats. This update is designed to deliver clear, accurate insights based on real patterns and changes we can verify. With today's complex systems, we need focused analysis—not noise.
What you'll see here isn't just a list of incidents, but a clear look at where control is being gained, lost, or quietly tested.
Threat of the Week
Lumma Stealer, DanaBot Operations Disrupted — A coalition of private sector companies and law enforcement agencies have taken down the infrastructure associated with Lumma Stealer and DanaBot. Charges have also been unsealed against 16 individuals for their alleged involvement in the development and deployment of DanaBot. The malware is equipped to siphon data from victim computers, hijack banking sessions, and steal device information. More uniquely, though, DanaBot has also been used for hacking campaigns that appear to be linked to Russian state-sponsored interests. All of that makes DanaBot a particularly clear example of how commodity malware has been repurposed by Russian state hackers for their own goals. In tandem, about 2,300 domains that acted as the command-and-controlbackbone for the Lumma information stealer have been seized, alongside taking down 300 servers and neutralizing 650 domains that were used to launch ransomware attacks. The actions against international cybercrime in the past few days constituted the latest phase of Operation Endgame.

Threat Actors Use TikTok Videos to Distribute Stealers — While ClickFix has become a popular social engineering tactic to deliver malware, threat actors have been observed using artificial intelligence-generated videos uploaded to TikTok to deceive users into running malicious commands on their systems and deploy malware like Vidar and StealC under the guise of activating pirated version of Windows, Microsoft Office, CapCut, and Spotify. "This campaign highlights how attackers are ready to weaponize whichever social media platforms are currently popular to distribute malware," Trend Micro said.
APT28 Hackers Target Western Logistics and Tech Firms — Several cybersecurity and intelligence agencies from Australia, Europe, and the United States issued a joint alert warning of a state-sponsored campaign orchestrated by the Russian state-sponsored threat actor APT28 targeting Western logistics entities and technology companies since 2022. "This cyber espionage-oriented campaign targeting logistics entities and technology companies uses a mix of previously disclosed TTPs and is likely connected to these actors' wide scale targeting of IP cameras in Ukraine and bordering NATO nations," the agencies said. The attacks are designed to steal sensitive information and maintain long-term persistence on compromised hosts.
Chinese Threat Actors Exploit Ivanti EPMM Flaws — The China-nexus cyber espionage group tracked as UNC5221 has been attributed to the exploitation of a pair of security flaws affecting Ivanti Endpoint Manager Mobilesoftwareto target a wide range of sectors across Europe, North America, and the Asia-Pacific region. The intrusions leverage the vulnerabilities to obtain a reverse shell and drop malicious payloads like KrustyLoader, which is known to deliver the Sliver command-and-controlframework. "UNC5221 demonstrates a deep understanding of EPMM's internal architecture, repurposing legitimate system components for covert data exfiltration," EclecticIQ said. "Given EPMM's role in managing and pushing configurations to enterprise mobile devices, a successful exploitation could allow threat actors to remotely access, manipulate, or compromise thousands of managed devices across an organization."
Over 100 Google Chrome Extensions Mimic Popular Tools — An unknown threat actor has been attributed to creating several malicious Chrome Browser extensions since February 2024 that masquerade as seemingly benign utilities such as DeepSeek, Manus, DeBank, FortiVPN, and Site Stats but incorporate covert functionality to exfiltrate data, receive commands, and execute arbitrary code. Links to these browser add-ons are hosted on specially crafted sites to which users are likely redirected to via phishing and social media posts. While the extensions appear to offer the advertised features, they also stealthily facilitate credential and cookie theft, session hijacking, ad injection, malicious redirects, traffic manipulation, and phishing via DOM manipulation. Several of these extensions have been taken down by Google.
CISA Warns of SaaS Providers of Attacks Targeting Cloud Environments — The U.S. Cybersecurity and Infrastructure Security Agencywarned that SaaS companies are under threat from bad actors who are on the prowl for cloud applications with default configurations and elevated permissions. While the agency did not attribute the activity to a specific group, the advisory said enterprise backup platform Commvault is monitoring cyber threat activity targeting applications hosted in their Microsoft Azure cloud environment. "Threat actors may have accessed client secrets for Commvault'sMicrosoft 365backup software-as-a-servicesolution, hosted in Azure," CISA said. "This provided the threat actors with unauthorized access to Commvault's customers' M365 environments that have application secrets stored by Commvault."
GitLab AI Coding Assistant Flaws Could Be Used to Inject Malicious Code — Cybersecurity researchers have discovered an indirect prompt injection flaw in GitLab's artificial intelligenceassistant Duo that could have allowed attackers to steal source code and inject untrusted HTML into its responses, which could then be used to direct victims to malicious websites. The attack could also leak confidential issue data, such as zero-day vulnerability details. All that's required is for the attacker to instruct the chatbot to interact with a merge requestby taking advantage of the fact that GitLab Duo has extensive access to the platform. "By embedding hidden instructions in seemingly harmless project content, we were able to manipulate Duo's behavior, exfiltrate private source code, and demonstrate how AI responses can be leveraged for unintended and harmful outcomes," Legit Security said. One variation of the attack involved hiding a malicious instruction in an otherwise legitimate piece of source code, while another exploited Duo's parsing of markdown responses in real-time asynchronously. An attacker could leverage this behavior – that Duo begins rendering the output line by line rather than waiting until the entire response is generated and sending it all at once – to introduce malicious HTML code that can access sensitive data and exfiltrate the information to a remote server. The issues have been patched by GitLab following responsible disclosure.

Sandworm Drops New Wiper in Ukraine — The Russia-aligned Sandworm group intensified destructive operations against Ukrainian energy companies, deploying a new wiper named ZEROLOT. "The infamous Sandworm group concentrated heavily on compromising Ukrainian energy infrastructure. In recent cases, it deployed the ZEROLOT wiper in Ukraine. For this, the attackers abused Active Directory Group Policy in the affected organizations," ESET Director of Threat Research, Jean-Ian Boutin, said. Another Russian hacking group, Gamaredon, remained the most prolific actor targeting the East European nation, enhancing malware obfuscation and introducing PteroBox, a file stealer leveraging Dropbox.
Signal Says No to Recall — Signal has released a new version of its messaging app for Windows that, by default, blocks the ability of Windows to use Recall to periodically take screenshots of the app. "Although Microsoft made several adjustments over the past twelve months in response to critical feedback, the revamped version of Recall still places any content that's displayed within privacy-preserving apps like Signal at risk," Signal said. "As a result, we are enabling an extra layer of protection by default on Windows 11 in order to help maintain the security of Signal Desktop on that platform even though it introduces some usability trade-offs. Microsoft has simply given us no other option." Microsoft began officially rolling out Recall last month.
Russia Introduces New Law to Track Foreigners Using Their Smartphones — The Russian government has introduced a new law that makes installing a tracking app mandatory for all foreign nationals in the Moscow region. This includes gathering their real-time locations, fingerprint, face photograph, and residential information. "The adopted mechanism will allow, using modern technologies, to strengthen control in the field of migration and will also contribute to reducing the number of violations and crimes in this area," Vyacheslav Volodin, chairman of the State Duma, said. "If migrants change their actual place of residence, they will be required to inform the Ministry of Internal Affairswithin three working days." A proposed four-year trial period begins on September 1, 2025, and runs until September 1, 2029.
Dutch Government Passes Law to Criminalize Cyber Espionage — The Dutch government has approved a law criminalizing a wide range of espionage activities, including digital espionage, in an effort to protect national security, critical infrastructure, and high-quality technologies. Under the amended law, leaking sensitive information that is not classified as a state secret or engaging in activities on behalf of a foreign government that harm Dutch interests can also result in criminal charges. "Foreign governments are also interested in non-state-secret, sensitive information about a particular economic sector or about political decision-making," the government said. "Such information can be used to influence political processes, weaken the Dutch economy or play allies against each other. Espionage can also involve actions other than sharing information."
Microsoft Announces Availability of Quantum-Resistant Algorithms to SymCrypt — Microsoft has revealed that it's making post-quantum cryptographycapabilities, including ML-KEM and ML-DSA, available for Windows Insiders, Canary Channel Build 27852 and higher, and Linux, SymCrypt-OpenSSL version 1.9.0. "This advancement will enable customers to commence their exploration and experimentation of PQC within their operational environments," Microsoft said. "By obtaining early access to PQC capabilities, organizations can proactively assess the compatibility, performance, and integration of these novel algorithms alongside their existing security infrastructure."
New Malware DOUBLELOADER Uses ALCATRAZ for Obfuscation — The open-source obfuscator ALCATRAZ has been seen within a new generic loader dubbed DOUBLELOADER, which has been deployed alongside Rhadamanthys Stealer infections starting December 2024. The malware collects host information, requests an updated version of itself, and starts beaconing to a hardcoded IP addressstored within the binary. "Obfuscators such as ALCATRAZ end up increasing the complexity when triaging malware," Elastic Security Labs said. "Its main goal is to hinder binary analysis tools and increase the time of the reverse engineering process through different techniques; such as hiding the control flow or making decompilation hard to follow."
New Formjacking Campaign Targets WooCommerce Sites — Cybersecurity researchers have detected a sophisticated formjacking campaign targeting WooCommerce sites. The malware, per Wordfence, injects a fake but professional-looking payment form into legitimate checkout processes and exfiltrates sensitive customer data to an external server. Further analysis has revealed that the infection likely originated from a compromised WordPress admin account, which was used to inject malicious JavaScript via a Simple Custom CSS and JS pluginthat allows administrators to add custom code. "Unlike traditional card skimmers that simply overlay existing forms, this variant carefully integrates with the WooCommerce site's design and payment workflow, making it particularly difficult for site owners and users to detect," the WordPress security company said. "The malware author repurposed the browser's localStorage mechanism – typically used by websites to remember user preferences – to silently store stolen data and maintain access even after page reloads or when navigating away from the checkout page."
E.U. Sanctions Stark Industries — The European Unionhas announced sanctions against 21 individuals and six entities in Russia over its "destabilising actions" in the region. One of the sanctioned entities is Stark Industries, a bulletproof hosting provider that has been accused of acting as "enablers of various Russian state-sponsored and affiliated actors to conduct destabilising activities including, information manipulation interference and cyber attacks against the Union and third countries." The sanctions also target its CEO Iurie Neculiti and owner Ivan Neculiti. Stark Industries was previously spotlighted by independent cybersecurity journalist Brian Krebs, detailing its use in DDoS attacks in Ukraine and across Europe. In August 2024, Team Cymru said it discovered 25 Stark-assigned IP addresses used to host domains associated with FIN7 activities and that it had been working with Stark Industries for several months to identify and reduce abuse of their systems. The sanctions have also targeted Kremlin-backed manufacturers of drones and radio communication equipment used by the Russian military, as well as those involved in GPS signal jamming in Baltic states and disrupting civil aviation.
The Mask APT Unmasked as Tied to the Spanish Government — The mysterious threat actor known as The Maskhas been identified as run by the Spanish government, according to a report published by TechCrunch, citing people who worked at Kaspersky at the time and had knowledge of the investigation. The Russian cybersecurity company first exposed the hacking group in 2014, linking it to highly sophisticated attacks since at least 2007 targeting high-profile organizations, such as governments, diplomatic entities, and research institutions. A majority of the group's attacks have targeted Cuba, followed by hundreds of victims in Brazil, Morocco, Spain, and Gibraltar. While Kaspersky has not publicly attributed it to a specific country, the latest revelation makes The Mask one of the few Western government hacking groups that has ever been discussed in public. This includes the Equation Group, the Lamberts, and Animal Farm.
Social Engineering Scams Target Coinbase Users — Earlier this month, cryptocurrency exchange Coinbase revealed that it was the victim of a malicious attack perpetrated by unknown threat actors to breach its systems by bribing customer support agents in India and siphon funds from nearly 70,000 customers. According to Blockchain security firm SlowMist, Coinbase users have been the target of social engineering scams since the start of the year, bombarding with SMS messages claiming to be fake withdrawal requests and seeking their confirmation as part of a "sustained and organized scam campaign." The goal is to induce a false sense of urgency and trick them into calling a number, eventually convincing them to transfer the funds to a secure wallet with a seed phrase pre-generated by the attackers and ultimately drain the assets. It's assessed that the activities are primarily carried out by two groups: low-level skid attackers from the Com community and organized cybercrime groups based in India. "Using spoofed PBX phone systems, scammers impersonate Coinbase support and claim there's been 'unauthorized access' or 'suspicious withdrawals' on the user's account," SlowMist said. "They create a sense of urgency, then follow up with phishing emails or texts containing fake ticket numbers or 'recovery links.'"
Delta Can Sue CrowdStrike Over July 2024 Mega Outage — Delta Air Lines, which had its systems crippled and almost 7,000 flights canceled in the wake of a massive outage caused by a faulty update issued by CrowdStrike in mid-July 2024, has been given the green light to pursue to its lawsuit against the cybersecurity company. A judge in the U.S. state of Georgia stating Delta can try to prove that CrowdStrike was grossly negligent by pushing a defective update to its Falcon software to customers. The update crashed 8.5 million Windows devices across the world. Crowdstrike previously claimed that the airline had rejected technical support offers both from itself and Microsoft. In a statement shared with Reuters, lawyers representing CrowdStrike said they were "confident the judge will find Delta's case has no merit, or will limit damages to the 'single-digit millions of dollars' under Georgia law." The development comes months after MGM Resorts International agreed to pay million to settle multiple class-action lawsuits related to a data breach in 2019 and a ransomware attack the company experienced in 2023.
Storm-1516 Uses AI-Generated Media to Spread Disinformation — The Russian influence operation known as Storm-1516sought to spread narratives that undermined the European support for Ukraine by amplifying fabricated stories on X about European leaders using drugs while traveling by train to Kyiv for peace talks. One of the posts was subsequently shared by Russian state media and Maria Zakharova, a senior official in Russia's foreign ministry, as part of what has been described as a coordinated disinformation campaign by EclecticIQ. The activity is also notable for the use of synthetic content depicting French President Emmanuel Macron, U.K. Labour Party leader Keir Starmer, and German chancellor Friedrich Merz of drug possession during their return from Ukraine. "By attacking the reputation of these leaders, the campaign likely aimed to turn their own voters against them, using influence operationsto reduce public support for Ukraine by discrediting the politicians who back it," the Dutch threat intelligence firm said.
Turkish Users Targeted by DBatLoader — AhnLab has disclosed details of a malware campaign that's distributing a malware loader called DBatLoadervia banking-themed banking emails, which then acts as a conduit to deliver SnakeKeylogger, an information stealer developed in .NET. "The DBatLoader malware distributed through phishing emails has the cunning behavior of exploiting normal processesthrough techniques such as DLL side-loading and injection for most of its behaviors, and it also utilizes normal processesfor behaviors such as file copying and changing policies," the company said.
SEC SIM-Swapper Sentenced to 14 Months for SEC X Account Hack — A 26-year-old Alabama man, Eric Council Jr., has been sentenced to 14 months in prison and three years of supervised release for using SIM swapping attacks to breach the U.S. Securities and Exchange Commission'sofficial X account in January 2024 and falsely announced that the SEC approved BitcoinExchange Traded Funds. Council Jr.was arrested in October 2024 and pleaded guilty to the crime earlier this February. He has also been ordered to forfeit According to court documents, Council used his personal computer to search incriminating phrases such as "SECGOV hack," "telegram sim swap," "how can I know for sure if I am being investigated by the FBI," "What are the signs that you are under investigation by law enforcement or the FBI even if you have not been contacted by them," "what are some signs that the FBI is after you," "Verizon store list," "federal identity theft statute," and "how long does it take to delete telegram account."
FBI Warns of Malicious Campaign Impersonating Government Officials — The U.S. Federal Bureau of Investigationis warning of a new campaign that involves malicious actors impersonating senior U.S. federal or state government officials and their contacts to target individuals since April 2025. "The malicious actors have sent text messages and AI-generated voice messages — techniques known as smishing and vishing, respectively — that claim to come from a senior US official in an effort to establish rapport before gaining access to personal accounts," the FBI said. "One way the actors gain such access is by sending targeted individuals a malicious link under the guise of transitioning to a separate messaging platform." From there, the actor may present malware or introduce hyperlinks that lead intended targets to an actor-controlled site that steals login information.
DICOM Flaw Enables Attackers to Embed Malicious Code Within Medical Image Files — Praetorian has released a proof-of-conceptfor a high-severity security flaw in Digital Imaging and Communications in Medicine, predominant file format for medical images, that enables attackers to embed malicious code within legitimate medical image files. CVE-2019-11687, originally disclosed in 2019 by Markel Picado Ortiz, stems from a design decision that allows arbitrary content at the start of the file, otherwise called the Preamble, which enables the creation of malicious polyglots. Codenamed ELFDICOM, the PoC extends the attack surface to Linux environments, making it a much more potent threat. As mitigations, it's advised to implement a DICOM preamble whitelist. "DICOM's file structure inherently allows arbitrary bytes at the beginning of the file, where Linux and most operating systems will look for magic bytes," Praetorian researcher Ryan Hennessee said. "would check a DICOM file's preamble before it is imported into the system. This would allow known good patterns, such as 'TIFF' magic bytes, or '\x00' null bytes, while files with the ELF magic bytes would be blocked."
Cookie-Bite Attack Uses Chrome Extension to Steal Session Tokens — Cybersecurity researchers have demonstrated a new attack technique called Cookie-Bite that employs custom-made malicious browser extensions to steal "ESTAUTH" and "ESTSAUTHPERSISTNT" cookies in Microsoft Azure Entra ID and bypass multi-factor authentication. The attack has multiple moving parts to it: A custom Chrome extension that monitors authentication events and captures cookies; a PowerShell script that automates the extension deployment and ensures persistence; an exfiltration mechanism to send the cookies to a remote collection point; and a complementary extension to inject the captured cookies into the attacker's browser. "Threat actors often use infostealers to extract authentication tokens directly from a victim's machine or buy them directly through darkness markets, allowing adversaries to hijack active cloud sessions without triggering MFA," Varonis said. "By injecting these cookies while mimicking the victim's OS, browser, and network, attackers can evade Conditional Access Policiesand maintain persistent access." Authentication cookies can also be stolen using adversary-in-the-middlephishing kits in real-time, or using rogue browser extensions that request excessive permissions to interact with web sessions, modify page content, and extract stored authentication data. Once installed, the extension can access the browser's storage API, intercept network requests, or inject malicious JavaScript into active sessions to harvest real-time session cookies. "By leveraging stolen session cookies, an adversary can bypass authentication mechanisms, gaining seamless entry into cloud environments without requiring user credentials," Varonis said. "Beyond initial access, session hijacking can facilitate lateral movement across the tenant, allowing attackers to explore additional resources, access sensitive data, and escalate privileges by abusing existing permissions or misconfigured roles."

Tip of the Week
Review and Revoke Old OAuth App Permissions — They're Silent Backdoor → You've likely logged into apps using "Continue with Google," "Sign in with Microsoft," or GitHub/Twitter/Facebook logins. That's OAuth. But did you know many of those apps still have access to your data long after you stop using them?
Why it matters:
Even if you delete the app or forget it existed, it might still have ongoing access to your calendar, email, cloud files, or contact list — no password needed. If that third-party gets breached, your data is at risk.
What to do:
Go through your connected apps here:
Google: myaccount.google.com/permissions
Microsoft: account.live.com/consent/Manage
GitHub: github.com/settings/applications
Facebook: facebook.com/settings?tab=applications
Revoke anything you don't actively use. It's a fast, silent cleanup — and it closes doors you didn't know were open.
Conclusion
Looking ahead, it's not just about tracking threats—it's about understanding what they reveal. Every tactic used, every system tested, points to deeper issues in how trust, access, and visibility are managed. As attackers adapt quickly, defenders need sharper awareness and faster response loops.
The takeaways from this week aren't just technical—they speak to how teams prioritize risk, design safeguards, and make choices under pressure. Use these insights not just to react, but to rethink what "secure" really needs to mean in today's environment.

"The adopted mechanism will allow, using modern technologies, to strengthen control in the field of migration and will also contribute to reducing the number of violations and crimes in this area," Vyacheslav Volodin, chairman of the State Duma, said. "If migrants change their actual place of residence, they will be required to inform the Ministry of Internal Affairswithin three working days." A proposed four-year trial period begins on September 1, 2025, and runs until September 1, 2029.
Dutch Government Passes Law to Criminalize Cyber Espionage — The Dutch government has approved a law criminalizing a wide range of espionage activities, including digital espionage, in an effort to protect national security, critical infrastructure, and high-quality technologies. Under the amended law, leaking sensitive information that is not classified as a state secret or engaging in activities on behalf of a foreign government that harm Dutch interests can also result in criminal charges. "Foreign governments are also interested in non-state-secret, sensitive information about a particular economic sector or about political decision-making," the government said. "Such information can be used to influence political processes, weaken the Dutch economy or play allies against each other. Espionage can also involve actions other than sharing information."
Microsoft Announces Availability of Quantum-Resistant Algorithms to SymCrypt — Microsoft has revealed that it's making post-quantum cryptographycapabilities, including ML-KEM and ML-DSA, available for Windows Insiders, Canary Channel Build 27852 and higher, and Linux, SymCrypt-OpenSSL version 1.9.0. "This advancement will enable customers to commence their exploration and experimentation of PQC within their operational environments," Microsoft said. "By obtaining early access to PQC capabilities, organizations can proactively assess the compatibility, performance, and integration of these novel algorithms alongside their existing security infrastructure."
New Malware DOUBLELOADER Uses ALCATRAZ for Obfuscation — The open-source obfuscator ALCATRAZ has been seen within a new generic loader dubbed DOUBLELOADER, which has been deployed alongside Rhadamanthys Stealer infections starting December 2024. The malware collects host information, requests an updated version of itself, and starts beaconing to a hardcoded IP addressstored within the binary. "Obfuscators such as ALCATRAZ end up increasing the complexity when triaging malware," Elastic Security Labs said. "Its main goal is to hinder binary analysis tools and increase the time of the reverse engineering process through different techniques; such as hiding the control flow or making decompilation hard to follow."
New Formjacking Campaign Targets WooCommerce Sites — Cybersecurity researchers have detected a sophisticated formjacking campaign targeting WooCommerce sites. The malware, per Wordfence, injects a fake but professional-looking payment form into legitimate checkout processes and exfiltrates sensitive customer data to an external server. Further analysis has revealed that the infection likely originated from a compromised WordPress admin account, which was used to inject malicious JavaScript via a Simple Custom CSS and JS pluginthat allows administrators to add custom code. "Unlike traditional card skimmers that simply overlay existing forms, this variant carefully integrates with the WooCommerce site's design and payment workflow, making it particularly difficult for site owners and users to detect," the WordPress security company said. "The malware author repurposed the browser's localStorage mechanism – typically used by websites to remember user preferences – to silently store stolen data and maintain access even after page reloads or when navigating away from the checkout page."
E.U. Sanctions Stark Industries — The European Unionhas announced sanctions against 21 individuals and six entities in Russia over its "destabilising actions" in the region. One of the sanctioned entities is Stark Industries, a bulletproof hosting provider that has been accused of acting as "enablers of various Russian state-sponsored and affiliated actors to conduct destabilising activities including, information manipulation interference and cyber attacks against the Union and third countries." The sanctions also target its CEO Iurie Neculiti and owner Ivan Neculiti. Stark Industries was previously spotlighted by independent cybersecurity journalist Brian Krebs, detailing its use in DDoS attacks in Ukraine and across Europe. In August 2024, Team Cymru said it discovered 25 Stark-assigned IP addresses used to host domains associated with FIN7 activities and that it had been working with Stark Industries for several months to identify and reduce abuse of their systems. The sanctions have also targeted Kremlin-backed manufacturers of drones and radio communication equipment used by the Russian military, as well as those involved in GPS signal jamming in Baltic states and disrupting civil aviation.
The Mask APT Unmasked as Tied to the Spanish Government — The mysterious threat actor known as The Maskhas been identified as run by the Spanish government, according to a report published by TechCrunch, citing people who worked at Kaspersky at the time and had knowledge of the investigation. The Russian cybersecurity company first exposed the hacking group in 2014, linking it to highly sophisticated attacks since at least 2007 targeting high-profile organizations, such as governments, diplomatic entities, and research institutions. A majority of the group's attacks have targeted Cuba, followed by hundreds of victims in Brazil, Morocco, Spain, and Gibraltar. While Kaspersky has not publicly attributed it to a specific country, the latest revelation makes The Mask one of the few Western government hacking groups that has ever been discussed in public. This includes the Equation Group, the Lamberts, and Animal Farm.
Social Engineering Scams Target Coinbase Users — Earlier this month, cryptocurrency exchange Coinbase revealed that it was the victim of a malicious attack perpetrated by unknown threat actors to breach its systems by bribing customer support agents in India and siphon funds from nearly 70,000 customers. According to Blockchain security firm SlowMist, Coinbase users have been the target of social engineering scams since the start of the year, bombarding with SMS messages claiming to be fake withdrawal requests and seeking their confirmation as part of a "sustained and organized scam campaign." The goal is to induce a false sense of urgency and trick them into calling a number, eventually convincing them to transfer the funds to a secure wallet with a seed phrase pre-generated by the attackers and ultimately drain the assets. It's assessed that the activities are primarily carried out by two groups: low-level skid attackers from the Com community and organized cybercrime groups based in India. "Using spoofed PBX phone systems, scammers impersonate Coinbase support and claim there's been 'unauthorized access' or 'suspicious withdrawals' on the user's account," SlowMist said. "They create a sense of urgency, then follow up with phishing emails or texts containing fake ticket numbers or 'recovery links.'"
Delta Can Sue CrowdStrike Over July 2024 Mega Outage — Delta Air Lines, which had its systems crippled and almost 7,000 flights canceled in the wake of a massive outage caused by a faulty update issued by CrowdStrike in mid-July 2024, has been given the green light to pursue to its lawsuit against the cybersecurity company. A judge in the U.S. state of Georgia stating Delta can try to prove that CrowdStrike was grossly negligent by pushing a defective update to its Falcon software to customers. The update crashed 8.5 million Windows devices across the world. Crowdstrike previously claimed that the airline had rejected technical support offers both from itself and Microsoft. In a statement shared with Reuters, lawyers representing CrowdStrike said they were "confident the judge will find Delta's case has no merit, or will limit damages to the 'single-digit millions of dollars' under Georgia law." The development comes months after MGM Resorts International agreed to pay million to settle multiple class-action lawsuits related to a data breach in 2019 and a ransomware attack the company experienced in 2023.
Storm-1516 Uses AI-Generated Media to Spread Disinformation — The Russian influence operation known as Storm-1516sought to spread narratives that undermined the European support for Ukraine by amplifying fabricated stories on X about European leaders using drugs while traveling by train to Kyiv for peace talks. One of the posts was subsequently shared by Russian state media and Maria Zakharova, a senior official in Russia's foreign ministry, as part of what has been described as a coordinated disinformation campaign by EclecticIQ. The activity is also notable for the use of synthetic content depicting French President Emmanuel Macron, U.K. Labour Party leader Keir Starmer, and German chancellor Friedrich Merz of drug possession during their return from Ukraine. "By attacking the reputation of these leaders, the campaign likely aimed to turn their own voters against them, using influence operationsto reduce public support for Ukraine by discrediting the politicians who back it," the Dutch threat intelligence firm said.
Turkish Users Targeted by DBatLoader — AhnLab has disclosed details of a malware campaign that's distributing a malware loader called DBatLoadervia banking-themed banking emails, which then acts as a conduit to deliver SnakeKeylogger, an information stealer developed in .NET. "The DBatLoader malware distributed through phishing emails has the cunning behavior of exploiting normal processesthrough techniques such as DLL side-loading and injection for most of its behaviors, and it also utilizes normal processesfor behaviors such as file copying and changing policies," the company said.
SEC SIM-Swapper Sentenced to 14 Months for SEC X Account Hack — A 26-year-old Alabama man, Eric Council Jr., has been sentenced to 14 months in prison and three years of supervised release for using SIM swapping attacks to breach the U.S. Securities and Exchange Commission'sofficial X account in January 2024 and falsely announced that the SEC approved BitcoinExchange Traded Funds. Council Jr.was arrested in October 2024 and pleaded guilty to the crime earlier this February. He has also been ordered to forfeit According to court documents, Council used his personal computer to search incriminating phrases such as "SECGOV hack," "telegram sim swap," "how can I know for sure if I am being investigated by the FBI," "What are the signs that you are under investigation by law enforcement or the FBI even if you have not been contacted by them," "what are some signs that the FBI is after you," "Verizon store list," "federal identity theft statute," and "how long does it take to delete telegram account."
FBI Warns of Malicious Campaign Impersonating Government Officials — The U.S. Federal Bureau of Investigationis warning of a new campaign that involves malicious actors impersonating senior U.S. federal or state government officials and their contacts to target individuals since April 2025. "The malicious actors have sent text messages and AI-generated voice messages — techniques known as smishing and vishing, respectively — that claim to come from a senior US official in an effort to establish rapport before gaining access to personal accounts," the FBI said. "One way the actors gain such access is by sending targeted individuals a malicious link under the guise of transitioning to a separate messaging platform." From there, the actor may present malware or introduce hyperlinks that lead intended targets to an actor-controlled site that steals login information.
DICOM Flaw Enables Attackers to Embed Malicious Code Within Medical Image Files — Praetorian has released a proof-of-conceptfor a high-severity security flaw in Digital Imaging and Communications in Medicine, predominant file format for medical images, that enables attackers to embed malicious code within legitimate medical image files. CVE-2019-11687, originally disclosed in 2019 by Markel Picado Ortiz, stems from a design decision that allows arbitrary content at the start of the file, otherwise called the Preamble, which enables the creation of malicious polyglots. Codenamed ELFDICOM, the PoC extends the attack surface to Linux environments, making it a much more potent threat. As mitigations, it's advised to implement a DICOM preamble whitelist. "DICOM's file structure inherently allows arbitrary bytes at the beginning of the file, where Linux and most operating systems will look for magic bytes," Praetorian researcher Ryan Hennessee said. "would check a DICOM file's preamble before it is imported into the system. This would allow known good patterns, such as 'TIFF' magic bytes, or '\x00' null bytes, while files with the ELF magic bytes would be blocked."
Cookie-Bite Attack Uses Chrome Extension to Steal Session Tokens — Cybersecurity researchers have demonstrated a new attack technique called Cookie-Bite that employs custom-made malicious browser extensions to steal "ESTAUTH" and "ESTSAUTHPERSISTNT" cookies in Microsoft Azure Entra ID and bypass multi-factor authentication. The attack has multiple moving parts to it: A custom Chrome extension that monitors authentication events and captures cookies; a PowerShell script that automates the extension deployment and ensures persistence; an exfiltration mechanism to send the cookies to a remote collection point; and a complementary extension to inject the captured cookies into the attacker's browser. "Threat actors often use infostealers to extract authentication tokens directly from a victim's machine or buy them directly through darkness markets, allowing adversaries to hijack active cloud sessions without triggering MFA," Varonis said. "By injecting these cookies while mimicking the victim's OS, browser, and network, attackers can evade Conditional Access Policiesand maintain persistent access." Authentication cookies can also be stolen using adversary-in-the-middlephishing kits in real-time, or using rogue browser extensions that request excessive permissions to interact with web sessions, modify page content, and extract stored authentication data. Once installed, the extension can access the browser's storage API, intercept network requests, or inject malicious JavaScript into active sessions to harvest real-time session cookies. "By leveraging stolen session cookies, an adversary can bypass authentication mechanisms, gaining seamless entry into cloud environments without requiring user credentials," Varonis said. "Beyond initial access, session hijacking can facilitate lateral movement across the tenant, allowing attackers to explore additional resources, access sensitive data, and escalate privileges by abusing existing permissions or misconfigured roles."

🔒 Tip of the Week
Review and Revoke Old OAuth App Permissions — They're Silent Backdoor → You've likely logged into apps using "Continue with Google," "Sign in with Microsoft," or GitHub/Twitter/Facebook logins. That's OAuth. But did you know many of those apps still have access to your data long after you stop using them?
Why it matters:
Even if you delete the app or forget it existed, it might still have ongoing access to your calendar, email, cloud files, or contact list — no password needed. If that third-party gets breached, your data is at risk.
What to do:
Go through your connected apps here:
Google: myaccount.google.com/permissions
Microsoft: account.live.com/consent/Manage
GitHub: github.com/settings/applications
Facebook: facebook.com/settings?tab=applications
Revoke anything you don't actively use. It's a fast, silent cleanup — and it closes doors you didn't know were open.
Conclusion
Looking ahead, it's not just about tracking threats—it's about understanding what they reveal. Every tactic used, every system tested, points to deeper issues in how trust, access, and visibility are managed. As attackers adapt quickly, defenders need sharper awareness and faster response loops.
The takeaways from this week aren't just technical—they speak to how teams prioritize risk, design safeguards, and make choices under pressure. Use these insights not just to react, but to rethink what "secure" really needs to mean in today's environment.
