GLASSWORM MALWARE RETURNS IN THIRD WAVE OF MALICIOUS VS CODE PACKAGES
Summary from the TLDR InfoSec newsletter
Glassworm malware returned for a third wave on OpenVSX and Microsoft Visual Studio marketplaces with 24 new packages impersonating popular developer tools. The supply chain attack evolved to use Rust-based implants alongside invisible Unicode character obfuscation, steals GitHub, npm, and OpenVSX credentials plus cryptocurrency wallet data from 49 extensions, deploys SOCKS proxies for traffic routing, and installs HVNC clients for stealthy remote access while manipulating download counts to boost search rankings. Development teams should immediately audit installed VS Code extensions against published IOC lists, verify publisher authenticity before installation, monitor for suspicious extension updates, and implement controls to detect invisible Unicode characters in code reviews to prevent credential theft and environment compromise.
