Hackers Hide Linux Malware in SSH-Like Package Filename

May 25, 2026 10:00 AM

Tags: attack, cyber, detection, hacker, linux, malicious, malware, software, supply-chain

Hackers have been observed disguising a malicious Linux payload under an SSH-like filename during software installation, as part of a coordinated supply chain attack targeting developer ecosystems. The attack hinges on a hidden post-install script embedded inside package.json, rather than the expected composer.json used in PHP environments. This subtle placement allows the malicious code to evade detection during routine dependency…
