How Signed Productivity Apps Are Being Used to Spread Malware (And How to Stay Safe) A new malware campaign known as TamperedChef has been spotted in the wild, and it takes advantage of something most users consider a sign of safety: valid digital signatures. Attackers are packaging malware inside seemingly legitimate, signed copies of popular productivity apps like Microsoft Teams, Slack, and Zoom. Once installed, the malware can steal credentials, log keystrokes, and give attackers remote access to your machine. Here’s what you need to know about this campaign and how to avoid becoming a victim. ...

What Your Medical Images Could Reveal: The Privacy Risks of AI in Radiology Artificial intelligence is transforming medical imaging at a rapid pace. Hospitals and clinics now use AI to help radiologists read X‑rays, CT scans, and MRIs faster and more accurately. That sounds like good news for patients, and in many ways it is. But there is a less visible side to this progress: the privacy of your medical images. ...

Medical AI Scans Your Images—But Who Else Sees Them? Privacy Risks You Should Know If you’ve had an X-ray, CT scan, or MRI in the last few years, chances are an artificial intelligence system analyzed part of that image. AI tools are now common in radiology—they help detect tumors, flag fractures, and speed up readings. The Radiological Society of North America (RSNA) reported in 2026 that AI integration in medical imaging is accelerating rapidly, with technology exhibitions at their annual meeting showcasing dozens of new diagnostic algorithms. ...

Is Your Medical Imaging AI Putting Your Privacy at Risk? What You Need to Know Artificial intelligence is now a regular part of medical imaging. From detecting tumors on CT scans to flagging fractures on X-rays, AI tools help radiologists work faster and more accurately. But as these systems become more common, a quieter concern has emerged: the risk that patient data can be exposed or re-identified through the very algorithms designed to improve care. ...

New Malware ‘TamperedChef’ Hides in Signed Productivity Apps to Steal Your Data Introduction A new malware strain called TamperedChef is making the rounds, and it has a twist that makes it especially hard to spot: it’s delivered inside productivity applications that are digitally signed. That signature—usually a sign of authenticity—is being used to lull users and security software into a false sense of safety. Reports from cybersecurity news outlets indicate that attackers are repackaging or tampering with signed installers of apps like Microsoft Teams, Slack, and Zoom to inject information stealers and remote access trojans (RATs). ...

How to Avoid Malware Hidden in Signed Productivity Apps (Like the New TamperedChef Attack) Most people assume that if an app is digitally signed, it’s safe. That assumption is exactly what attackers behind the recently reported TamperedChef campaign are exploiting. They are distributing malware via productivity apps that carry valid digital signatures, making the software look legitimate and bypassing many typical security checks. ...

Your Medical Scans Could Be Leaking Private Data: What to Know About AI and Imaging If you’ve had an X-ray, MRI, or CT scan recently, there’s a good chance an artificial intelligence tool helped analyze the results. AI in radiology can speed up diagnoses and catch things the human eye might miss. But there’s a catch: the same technology that makes imaging more powerful also creates new risks for your personal health data. ...

TamperedChef Malware: How Signed Productivity Apps Are Being Used to Spread Stealers and RATs Intro Recent reports describe a malware campaign called TamperedChef that delivers stealers and remote access trojans (RATs) by bundling them with seemingly legitimate productivity applications. What makes this campaign notable is that the malicious executables carry valid digital signatures—something that can trick both users and some security tools into assuming the software is safe. ...

Your Medical Scans Could Be Used for AI Training—and That Raises Privacy Risks You go in for a routine X-ray or an MRI. The image helps your doctor diagnose a fracture or spot an abnormality. What you may not realize is that the same image could later end up in a database used to train artificial intelligence software—and with that come privacy risks that experts say aren’t being fully addressed. ...

How to Spot Malware Hidden in Signed Productivity Apps (And Stay Safe) Imagine downloading what looks like the latest version of Slack or Microsoft Teams, seeing a digital signature that says the file is from the publisher you expect, and running it without a second thought. That’s the exact scenario the TamperedChef malware campaign exploits. Security researchers reported on May 21, 2026, that attackers are using legitimately signed installers to slip stealers and remote access trojans (RATs) onto computers. For anyone who installs productivity software regularly—especially remote workers and business professionals—this is a reminder that a digital signature alone is no longer a guarantee of safety. ...
