New Malware ‘TamperedChef’ Hides Inside Signed Apps – How to Stay Safe If you’ve ever downloaded a free productivity tool from a site you don’t quite trust, you’re not alone. Many of us do it to save money or time. But there’s a new threat that exploits that habit with a nasty twist: malware that carries a valid digital signature, making it look legitimate right up until the moment it steals your passwords or gives an attacker remote control of your machine. ...

What You Need to Know About Privacy Risks When AI Analyzes Your Medical Scans If you’ve had an X-ray, MRI, or CT scan recently, there’s a good chance an artificial intelligence tool helped your radiologist interpret the images. Hospitals and imaging centers are adopting AI faster than ever to speed up diagnoses and catch subtle findings. But this rapid shift brings a less visible problem: serious privacy risks for your medical images. ...

New Malware Hides in Signed Apps: How to Stay Safe from TamperedChef A new malware campaign called TamperedChef is making the rounds, using digitally signed productivity applications to deliver information stealers and remote access trojans (RATs). The campaign was reported by CyberSecurityNews on May 21, 2026. What makes this attack particularly worrisome is that the malicious apps carry valid cryptographic signatures, which often causes both users and security software to let their guard down. ...

The Hidden Privacy Costs of AI in Medical Imaging: What Every Patient Should Know Artificial intelligence is reshaping radiology. Algorithms can now spot tumors, measure organ volumes, and flag abnormalities faster than many radiologists. That promises better outcomes. But there is a less visible trade-off: your medical images are becoming far more valuable—and vulnerable—than their pixels suggest. ...

TamperedChef Malware: How Signed Productivity Apps Are Delivering Stealers and RATs A new malware campaign called TamperedChef is making it harder to tell safe app installers from dangerous ones. Attackers are using digitally signed installers that look exactly like popular productivity software—Zoom, Microsoft Teams, Slack—but actually contain credential stealers and remote access trojans (RATs). The campaign was detailed by CyberSecurityNews on May 21, 2026, and it’s a reminder that even a “verified publisher” warning in Windows isn’t a guarantee of safety. ...

Beware: Signed Productivity Apps Now Spreading Stealer Malware — How to Stay Safe If you’ve ever downloaded a productivity app like Microsoft Office or a tool from a well-known publisher, you may have noticed that the installer displays a “signed by” message. That digital signature is meant to guarantee the software comes from a legitimate source and hasn’t been tampered with. But a new malware campaign called TamperedChef is exploiting that trust. According to recent cybersecurity reports, attackers are using signed applications—often repackaged versions of popular productivity software—to deliver information stealers and remote access trojans (RATs) to unsuspecting users. ...

Title: What You Need to Know About Privacy Risks in Medical Imaging AI Introduction If you’ve had an X-ray, MRI, or CT scan recently, there’s a good chance an artificial intelligence system was involved in reading or analyzing those images. Hospitals and clinics are adopting AI tools at a fast pace—especially in radiology—to help detect tumors, fractures, and other abnormalities more quickly.

If you use tools like Notepad++, 7‑Zip, or other free utilities, it is worth understanding how this works and what you can do to stay safe. ...

What Medical Imaging AI Means for Your Privacy – and What You Can Do About It Artificial intelligence is increasingly used to help radiologists read X-rays, MRIs, and CT scans. It can speed up diagnosis, catch subtle abnormalities, and reduce workload. But as AI tools become more common in medical imaging, a quieter issue is emerging: what happens to the data in those images once they are used by AI systems? ...

How to Protect Yourself from TamperedChef Malware That Hides in Signed Productivity Apps Recent reports have highlighted a malware campaign called TamperedChef that exploits a common trust mechanism: code signing. Attackers are tampering with legitimate productivity applications — such as Office tools, project management software, and note-taking apps — and then signing the altered files with stolen or forged digital certificates. Once installed, the malware delivers information stealers and remote access trojans (RATs) that can compromise personal data, login credentials, and even give attackers control over the device. ...
