When a Signed App Isn’t Safe: The TamperedChef Malware and How to Protect Yourself Intro Most people assume that if a program is “signed” by a developer, it’s safe to install. That assumption is the exact thing attackers are starting to exploit. A newly documented campaign, named TamperedChef, is delivering password stealers and remote access tools inside productivity applications that carry valid digital signatures. Understanding how this works — and what you can actually do about it — matters more now than ever. ...

Don’t Trust Signed Apps Blindly: How TamperedChef Malware Hides in Productivity Tools Most of us assume that if an app comes with a legitimate-looking digital signature it’s safe. After all, code signing is supposed to verify the software’s publisher and guarantee it hasn’t been tampered with. But a recent wave of attacks known as TamperedChef shows that assumption can be costly. Attackers are using stolen or forged digital certificates to sign malicious installers that look like everyday productivity apps—PDF editors, office suites, and project management tools. Once installed, the malware steals credentials, installs remote access trojans (RATs), and can give attackers full control over your device. Here’s what you need to know and how to protect yourself. ...
