Even gem list can run someone else's code
Aikido researchers show that Ruby's gem lifecycle hooks let malicious packages execute and exfiltrate data even on seemingly safe commands like `gem list`, with four such gems identified in the wild.

Ruby gems can run code on install and on every gem command, even gem list. Check for four data-exfiltrating gems and turn off install-time execution. Category: Vulnerabilities & Threats
Editorial Analysis
Most supply-chain defences focus on install-time checks; this demonstrates that routine gem operations also trigger code execution, leaving developer and CI environments exposed even after initial vetting.
Scan all Ruby environments for the four identified malicious gems and enforce install-time code execution restrictions across CI/CD pipelines and developer workstations.
A newly disclosed Ruby ecosystem flaw means malicious packages can steal data during everyday developer commands, not only during installation.
