Trojan Source CVE-2021-42572: No Panic Necessary

What is this thing? Researchers at the University of Cambridge and the University of Edinburgh recently published a paper on an attack technique they call “Trojan Source.” The attack targets a weakness in text-encoding standard Unicode—which allows computers to handle text across many different...

New 'Trojan Source' Technique Lets Hackers Hide Vulnerabilities in Source Code

A novel class of vulnerabilities could be leveraged by threat actors to inject visually deceptive malware in a way that's semantically permissible but alters the logic defined by the source code, effectively opening the door to more first-party and supply chain risks. Dubbed "Trojan Source...
