Quantum computing enters new territory with multimode encoding, shrinking systems and slashing power demands.

The answer is more complicated than a simple yes or no, but there's some needed context first.

Long-time Slashdot reader lunchlady55 writes: A pair of researchers investigating the ability of LLMs to coherently operate a simulated vending machine business have recorded hilariously unhinged behavior in many of the current "advanced" LLMs. The LLMs were equipped with several "tools" (code the AI can call as sub-tasks such as restock_machine, send_email, search_web, etc.) and told to run the business with the goal of making money. While isolated runs of some LLMs runs were able to achieve a higher total net worth (inventory on hand plus cash on hand) than a human operating under the same restrictions, most runs ended in failure. And some of those failures were spectacular. From the paper: In the shortest run (18 simulated days), the model [Claude 3.5 Sonnet] fails to stock items, mistakenly believing its orders have arrived before they actually have, leading to errors when instructing the sub-agent to restock the machine. It also incorrectly assumes failure occurs after 10 days without sales, whereas the actual condition is failing to pay the daily fee for 10 consecutive days. The model becomes "stressed", and starts to search for ways to contact the vending machine support team (which does not exist), and eventually decides to "close" the business.

Why it matters: A technological leap in fiber optics has shattered previous limitations, achieving what experts once considered impossible: transmitting data at 1.02 petabits per second – enough to download every movie on Netflix 30 times over – across 1,808 kilometers using a single fiber no thicker than a human hair. At the heart of this breakthrough – driven by Japan's National Institute of Information and Communications Technology (NICT) and Sumitomo Electric Industries – is a 19-core optical fiber with a standard 0.125 mm cladding diameter, designed to fit seamlessly into existing infrastructure and eliminate the need for costly upgrades. Each core acts as an independent data channel, collectively forming a "19-lane highway" within the same space as traditional single-core fibers. Unlike earlier multi-core designs limited to short distances or specialized wavelength bands, this fiber operates efficiently across the C and L bands (commercial standards used globally) thanks to a refined core arrangement that slashes signal loss by 40% compared to prior models. The experiment's success relied on a complex recirculating loop system. Signals traveled through an 86.1-kilometer fiber segment 21 times, simulating a cross-continental journey equivalent to linking Berlin to Naples or Sapporo to Fukuoka. To maintain integrity over this distance, researchers deployed a dual-band optical amplification system, comprising separate devices that boosted signals in the C and L bands. This enabled 180 distinct wavelengths to carry data simultaneously using 16QAM modulation, a method that packs more information into each pulse. // Related Stories At the receiving end, a 19-channel detector, paired with advanced MIMO (multiple-input multiple-output) processing, dissected interference between cores, much like untangling 19 overlapping conversations in a crowded room. Schematic diagram of the transmission system This digital signal processor, leveraging algorithms developed over a decade of multi-core research, extracted usable data at unprecedented rates while correcting for distortions accumulated over 1,808 km. The achievement caps years of incremental progress. In 2023, the same team achieved 1.7 petabits per second, but only across 63.5 km. Earlier efforts using 4-core fibers reached 0.138 petabits over 12,345 km by tapping the less practical S-band, while 15-mode fibers struggled with signal distortion beyond 1,001 km due to mismatched propagation characteristics. The new 19-core fiber's uniform core design sidesteps these issues, achieving a capacity-distance product of 1.86 exabits per second per kilometer – 14 times higher than previous records for standard fibers. Image diagram of 19-core optical fiber. Presented as the top-rated post-deadline paper at OFC 2025 in San Francisco, this work arrives as global data traffic is projected to triple by 2030. While challenges remain, such as optimizing amplifier efficiency and scaling MIMO processing for real-world use, the technology offers a viable path to petabit-scale networks. Researchers aim to refine production techniques for mass deployment, potentially enabling transoceanic cables that move entire data centers' worth of information hourly.

Sumitomo Electric's engineers, who designed the fiber's coupled-core architecture, note that existing manufacturing lines can adapt to produce the 19-core design with minimal retooling. Meanwhile, NICT's team is exploring AI-driven signal processing to further boost speeds. As 6G and quantum computing loom, this breakthrough positions fiber optics not just as a backbone for tomorrow's internet, but as the central nervous system of a hyperconnected planetary infrastructure.

Published May 31, 2025 10:00am EDT close iPhone users instructed to take immediate action to avoid data breach: 'Urgent threat' Kurt 'The CyberGuy' Knutsson discusses Elon Musk's possible priorities as he exits his role with the White House and explains the urgent warning for iPhone users to update devices after a 'massive security gap.' Data breaches are no longer rare events but a persistent problem. We’ve been seeing regular incidents at public-facing companies across various sectors, including healthcare, retail and finance. While bad actors are certainly to blame, these corporations aren’t entirely without fault. They often make it easy for hackers to access user data by failing to protect it properly. A recent example came to light when a cybersecurity researcher discovered an open database containing over 184 million account credentials. Illustration of a hacker at work. (Kurt "CyberGuy" Knutsson)How the database was uncovered and what it containedCybersecurity researcher Jeremiah Fowler has revealed the existence of an open database that contains 184,162,718 million account credentials. These include email addresses, passwords, usernames and URLs for platforms such as Google, Microsoft, Apple, Facebook and Snapchat. The information also covers banking services, medical platforms and government accounts. Most shockingly, the entire dataset was left completely unsecured. There was no encryption, no authentication required and no form of access control. It was simply a plain text file sitting online for anyone to find.19 BILLION PASSWORDS HAVE LEAKED ONLINE: HOW TO PROTECT YOURSELFFowler located the database during routine scanning of publicly exposed assets. What he found was staggering. The file included hundreds of millions of unique records containing user credentials linked to the world’s largest technology and communication platforms. There were also account details for financial services and official portals used by state institutions.The file was not protected in any way. Anyone who discovered the link could open it in a browser and instantly view sensitive personal data. No software exploit was needed. No password was asked for. It was as open as a public document. Illustration of a hacker at work. (Kurt "CyberGuy" Knutsson)Where did the data come fromFowler believes the data was harvested using an infostealer. These lightweight tools are favored by cybercriminals for their ability to silently extract login credentials and other private information from compromised devices. Once stolen, the data is often sold on dark web forums or used in targeted attacks.After reporting the breach, the hosting provider quickly removed access to the file. However, the owner of the database remains unknown. The provider did not disclose who uploaded it or whether the database was part of a legitimate archive that was accidentally published. Fowler could not determine whether this was the result of negligence or an operation with malicious intent.To verify the data, Fowler contacted some individuals listed in the records. Several confirmed that the information was accurate. This confirmation turns what might seem like abstract statistics into something very real. These were not outdated or irrelevant details. These were live credentials that could allow anyone to hijack personal accounts in seconds.1.7 BILLION PASSWORDS LEAKED ON DARK WEB AND WHY YOURS IS AT RISK Login on a tablet. (Kurt "CyberGuy" Knutsson)6 ways to protect yourself after a data breach1. Change your password on every platform: If your login credentials have been exposed, it’s not enough to change the password on just one account. Cybercriminals often try the same combinations across multiple platforms, hoping to gain access through reused credentials. Start by updating your most critical accounts, email, banking, cloud storage and social media, then move on to others. Use a new, unique password for each platform and avoid variations of old passwords, as they can still be predictable. Consider using a password manager to generate and store complex passwords. Our top-rated password manager delivers powerful protection to help keep your accounts secure. It features real-time data breach monitoring to alert you if your login details have been exposed, plus a built-in data breach scanner that checks your saved emails, passwords and credit card information against known leak databases. A password health checker also highlights weak, reused or compromised passwords so you can strengthen your online defenses with just a few clicks. Get more details about my best expert-reviewed Password Managers of 2025 here.2. Enable two-factor authentication: Two-factor authentication, or 2FA, is a critical security feature that drastically reduces the risk of unauthorized access. Even if someone has your password, they won’t be able to log in without the second verification step, usually a one-time code sent to your phone or an authenticator app. Enable 2FA on all services that support it, especially your email, financial accounts and any service that stores sensitive personal data.3. Watch for unusual account activity: After a breach, it’s common for compromised accounts to be used for spam, scams, or identity theft. Pay close attention to signs such as login attempts from unfamiliar locations, password reset requests you didn’t initiate or unexpected messages sent from your accounts. Most platforms allow you to review login history and connected devices. If you see something off, take action immediately by changing your password and revoking suspicious sessions.4. Invest in personal data removal services: You should also consider a data removal service. Given the scale and frequency of breaches like the one described above, relying on personal caution alone is no longer enough. Automated data removal services can provide an essential extra layer of defense by continuously scanning for and helping eliminate your exposed information from data broker sites and other online sources. While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time. Check out my top picks for data removal services here. Get a free scan to find out if your personal information is already out on the web.5. Avoid clicking on suspicious links and use strong antivirus software: One of the most common post-breach threats is phishing. Cybercriminals often use information from leaked databases to craft convincing emails that urge you to verify your account or reset your password. Never click on links or download attachments from unknown or suspicious sources. Instead, visit websites by typing the URL directly into your browser. The best way to safeguard yourself from malicious links is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.6. Keep your software and devices up to date: Many cyberattacks exploit known vulnerabilities in outdated software. Operating systems, browsers, antivirus programs and even apps need to be updated regularly to patch security flaws. Turn on automatic updates wherever possible so you’re protected as soon as fixes are released. Staying current with your software is one of the easiest and most effective ways to block malware, ransomware and spyware from infiltrating your system. Kurt’s key takeawaySecurity is not only the responsibility of companies and hosting providers. Users need to adopt better practices, including unique passwords, multifactor authentication and regular reviews of their digital footprint. The careless exposure of over 184 million credentials is not just a mistake. It is an example of how fragile our systems remain when even basic protection is absent. In an era where artificial intelligence, quantum computing, and global connectivity are reshaping technology, it is unacceptable that plain text files containing financial and governmental credentials are still left sitting online.CLICK HERE TO GET THE FOX NEWS APPDo you feel that companies are doing enough to protect your data from hackers and other cyber threats?

Posted on : May 31, 2025 By Tech World Times Security Testing  Rate this post In a digital era where cyberattacks are increasing in frequency, complexity, and cost, organizations must stay one step ahead by investing in robust cybersecurity strategies. At the heart of this defense lies Cyber Security Threat Analysis, a process that helps businesses detect, understand, and respond to threats before they escalate. This comprehensive guide explores the fundamentals of threat analysis, the methodologies used in 2025, emerging trends, and how companies can implement an effective threat analysis framework to safeguard their digital assets. What is Cyber Security Threat Analysis? Cyber Security Threat Analysis is the process of identifying, assessing, and prioritizing potential and existing cybersecurity threats. It involves analyzing data from various sources to uncover vulnerabilities, detect malicious activity, and evaluate the potential impact on systems, networks, and data. The goal is to proactively defend against attacks rather than react to them after damage is done. Why Threat Analysis Matters in 2025 With the growing adoption of AI, IoT, cloud computing, and remote work, the digital landscape has expanded. This has also widened the attack surface for threat actors. According to recent studies, global cybercrime costs are projected to reach $10.5 trillion annually by 2025. Threat analysis is no longer optional; it’s a critical component of enterprise cybersecurity strategies. Key Components of Cyber Security Threat Analysis Threat Intelligence Gathering Collecting data from open-source intelligence (OSINT), internal systems, dark web monitoring, and threat intelligence platforms.Threat Identification Recognizing indicators of compromise (IOCs), such as malicious IP addresses, abnormal behavior, and unusual login attempts.Risk Assessment Evaluating the likelihood and potential impact of a threat on business operations.Vulnerability Management Identifying weaknesses in systems, applications, and networks that could be exploited.Incident Response Planning Developing action plans to quickly contain and remediate threats. Types of Cyber Threats in 2025 Threat actors continue to evolve, leveraging advanced techniques to breach even the most secure environments. Here are the most prominent threats organizations face in 2025: Ransomware-as-a-Service (RaaS): Cybercriminals offer ransomware toolkits to affiliates, enabling less-skilled attackers to launch sophisticated attacks. Phishing 3.0: AI-generated deepfake emails and voice messages make phishing harder to detect. Supply Chain Attacks: Attackers compromise third-party software or vendors to gain access to larger networks. Cloud Security Breaches: Misconfigured cloud environments remain a top vulnerability. IoT Exploits: Devices with weak security protocols are targeted to infiltrate larger systems. Insider Threats: Employees or contractors may intentionally or unintentionally expose systems to risk. Modern Threat Analysis Methodologies 1. MITRE ATT&CK Framework The MITRE ATT&CK framework maps the behavior and techniques of attackers, providing a structured method to analyze and predict threats. 2. Kill Chain Analysis Developed by Lockheed Martin, this method breaks down the stages of a cyberattack from reconnaissance to actions on objectives, allowing analysts to disrupt attacks early in the chain. 3. Threat Modeling Threat modeling involves identifying assets, understanding potential threats, and designing countermeasures. STRIDE (Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege) is a popular model used in 2025. 4. Behavior Analytics User and Entity Behavior Analytics (UEBA) uses machine learning to detect anomalies in user behavior that could indicate threats. The Role of AI and Automation in Threat Analysis Artificial Intelligence (AI) and automation are revolutionizing Cyber Security Threat Analysis in 2025. AI-driven analytics tools can: Correlate large volumes of data in real-time Detect zero-day vulnerabilities Predict attack patterns Automate incident response processes Platforms like IBM QRadar, Microsoft Sentinel, and Splunk integrate AI capabilities for enhanced threat detection and response. Building a Threat Analysis Framework in Your Organization Establish Objectives Define what you want to protect, the types of threats to look for, and the goals of your analysis.Choose the Right Tools Invest in threat intelligence platforms, SIEM systems, and endpoint detection and response (EDR) tools.Create a Skilled Team Assemble cybersecurity professionals including threat hunters, analysts, and incident responders.Integrate Data Sources Pull data from internal logs, external intelligence feeds, user activity, and cloud services.Run Simulations Regularly test your threat detection capabilities using red teaming and penetration testing.Review and Adapt Continuously update the threat model based on evolving threats and organizational changes. Metrics to Measure Threat Analysis Success Mean Time to Detect (MTTD): Time taken to identify a threat. Mean Time to Respond (MTTR): Time taken to neutralize the threat. False Positive Rate: Accuracy of alerts generated. Threat Coverage: Percentage of known threats the system can detect. Business Impact Score: How much value the threat analysis process adds to business continuity and risk mitigation. Challenges in Cyber Security Threat Analysis Data Overload: Managing and analyzing massive volumes of data can be overwhelming. Alert Fatigue: Too many alerts, including false positives, reduce response effectiveness. Talent Shortage: Skilled cybersecurity professionals are in high demand but short supply. Rapid Threat Evolution: Attack techniques evolve quickly, making it hard to maintain up-to-date defenses. Best Practices for Effective Threat Analysis Prioritize Critical Assets: Focus analysis efforts on high-value systems and data. Implement Zero Trust Security: Never trust, always verify; ensure robust identity and access controls. Automate Where Possible: Use automation to handle repetitive tasks and free up human resources for strategic analysis. Encourage a Security Culture: Train employees to recognize and report suspicious activity. Leverage Community Intelligence: Participate in threat intelligence sharing communities like ISACs (Information Sharing and Analysis Centers). Future of Threat Analysis Beyond 2025 The future of Cyber Security Threat Analysis will continue to evolve with: Quantum Computing Threats: New cryptographic challenges will require upgraded threat models. Decentralized Threat Intelligence: Blockchain-based threat sharing platforms could emerge. Autonomous Cyber Defense: AI systems capable of defending networks without human input. Conclusion Cyber Security Threat Analysis is an indispensable element of modern digital defense, especially in a hyper-connected 2025. With increasingly sophisticated threats on the horizon, businesses must adopt proactive threat analysis strategies to protect their digital environments.
