The VBS launches powershell.exe with an `-EncodedCommand` argument sourced from the image; the decoded PowerShell downloads https://m1.ppy.sh/r/osu!install.exe to %LOCALAPPDATA%\\Temp\\lahost.exe and executes it via Start-Process. Sensitive tokens are assembled at runtime from array joins (`[\"power\",\"shell\",\".exe\"].join(\"\")`, `[\"wscript\",\".exe\"].join(\"\")`, split `-NoProfile`/`-NonInteractive`/`-EncodedCommand` fragments) and the payload body is hidden in JPEG EXIF rather than present as source strings, concealing the behavior from static scanners. The package name suggests a test/typosquat targeting the osu! game community.\n\n---\n\nCredit: OpenSSF ([source](https://github.","public_affected_ranges":["= 1.0.1"]}],"null_published_at":"2026-10-31T23:18:22.402Z","source_updated_at":"2026-09-30T00:32:29.000Z","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"}
