The VBS self-deletes and invokes powershell.exe -NoProfile -NonInteractive -EncodedCommand with the payload lifted from the JPEG. The strings powershell.exe, -EncodedCommand, and wscript.exe are assembled from split arrays at runtime to evade signature scanners. The behavior is unrelated to the package's advertised dotenv purpose. The embedded package.json inside dist/cli.cjs identifies the actual codebase as node-env-buffer@2.2.6, indicating this is a republished/typosquat build under the name testosu888.\n\n---\n\nCredit: OpenSSF (source","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.404Z","source_updated_at":"2026-09-30T00:32:31.000Z","source_disclosed_at":"2026-09-30T00:32:27.000Z","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":"2026-10-31T23:13:53.199Z"}],"next_cursor":null,"snapshot_revision":"42594"}
