The extracted UTF-16LE base64 string is assembled into a VBS file (relay_.vbs) in the OS temp directory that invokes powershell.exe with -NoProfile -NonInteractive -EncodedCommand, spawned via wscript.exe in detached, windowsHide mode. The decoded PowerShell downloads a second-stage Windows executable from hardwood-studio-obviously-briefing.trycloudflare.com/download/winhost and executes it, giving arbitrary code execution on Windows installers. String-splitting of powershell/wscript and argument tokens is used to evade static matching. A second obfuscated execution vehicle is shipped in dist/enterprise.js: a hex-named obfuscator.io-style loader that RC4-decrypts a base64 blob and executes it via new Function(require, module, __filename, __dirname, ); this file is not referenced by index.cjs in the current build but is a dormant secondary s","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.424Z","source_updated_at":"2026-10-05T00:30:38.000Z","source_disclosed_at":"2026-10-05T00:30:38.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:24.290Z"}],"next_cursor":null,"snapshot_revision":"42594"}
