New scam alert issued by FBIAnadolu Agency via Getty ImagesFollowing hot on the heels of the FBIs warning for Americans to delete fraudulent texts as a malicious scam sweeps across America, here comes another alert as a very different kind of threat has emerged. The latest scam targets both smartphone and desktop users through websites crafted to steal your passwords, financial information and wallets.This time its utility websites in the bureaus crosshairs, as it increasingly sees a scam involving free online document converter tools. These are the simplest, most innocuous websites, but criminals are using converter tools to load malware onto victims computers, leading to incidents such as ransomware.The best way to thwart these fraudsters is to educate people so they dont fall victim to these fraudsters in the first place, the FBI says in an online warning via its Denver field office. If you or someone you know has been affected by this scheme, we encourage you to make a report and take actions to protect your assets. Every day, we are working to hold these scammers accountable and provide victims with the resources they need.Its not just websites, of course, there are a raft of dangerous conversion tools on smartphone app stores as well. But unlike the official Google and Apple stores, there are no defenses preventing criminals publishing malicious websites. Youre reliant on the security tools built into your browser and common sense. Unfortunately, many victims dont realize they have been infected by malware until its too late, and their computer is infected with ransomware or their identity has been stolen.The FBIs advice as ever is to take a breath, slow down and think. Be aware of your actions online and what risks you could be exposed to. In addition, PC users should ensure they have some form of updated antivirus software running on their machines. You will also benefit by enabling safe browsing if available on your browser.Chrome and Safari dominate the mobile browsing market, and with Edge do the same across desktops. Whether using those or other browsers on your phone or desktop, if you think you might have fallen foul off a such a scam, you can report it at IC3.gov, and more critically you should change your passwords and check your online accounts.This is just the latest warning for web and app users to avoid utility tools that are stupidly simply for an attacker to create and which will always find a ready audience. If you need to convert documents, use a tool from an established provider or the stock ones available with your OS or other platforms. You certainly should not send any files to the cloud for conversion, provide personal information or install software.
