RubyGems Namespace Reuse Enables 16 Typosquatted Gems to Deliver Rust-Go Stealer Chain
Sixteen typosquatted RubyGems abused namespace reclamation and extconf.rb hooks to deploy a Rust-Go credential stealer. The campaign exposed unvalidated author fields and permanent namespace release after yanks. Registry design flaws enable rapid revival of yanked package names by new accounts.

RubyGems maintainers must implement author verification and namespace reservation after yank. Without changes, the attack surface remains identical for any dependency popular enough to attract clumsy typosquats. Monitoring for extconf.rb fetching external binaries provides the highest fidelity detection signal.
⚡ Prediction
OpenSourceMalware: At least three additional reclaimed gems will appear on RubyGems within 90 days using the same two owner accounts.
