‘Trojan Source’ Hides Invisible Bugs in Source Code

Researchers have found a new way to encode potentially evil source code, such that human reviewers see a harmless version and compilers see the invisible, wicked version. Named “Trojan Source attacks,” the method “exploits subtleties in text-encoding standards such as Unicode to produce source co...

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...
