Cybersecurity researchers have flagged dozens of Microsoft Visual Studio Code (VS Code) extensions on the Open VSX repository that are linked to a persistent information-stealing campaign dubbed GlassWorm . The cluster of 73 extensions has been identified as cloned versions of their legitimate counterparts. Of these, six have been confirmed to be malicious, with the remaining acting as seemingly harmless sleeper packages to get users to download them and build trust, before their true intent is manifested through a subsequent update. All the extensions were published at the start of the month, per application security company Socket, which is tracking the latest iteration under the moniker GlassWorm v2 . In total, more than 320 artifacts have been identified since December 21, 2025. The list of extensions identified as malicious is below - outsidestormcommand.monochromator-theme keyacrosslaud.auto-loop-for-antigravity krundoven.ironplc-fast-hub boulderzitunnel.vscode-buddies ...
