Achroma SVG
AI Security Review
scanned 15d ago · by lpm-firewall-aiThe package entry point is an SVG that loads heavily obfuscated JavaScript with remote-fetch behavior, and the page also injects a remote transport script. This is an active remote-code loading chain, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
Opening index.svg in a browser or SVG-capable viewer.
Impact
Remote code can execute in the page’s context, exposing the viewer to behavior controlled by the remote resources.
Mechanism
The SVG loads achroma.js; that script fetches remote content, while the page creates a script element for a transport client hosted on cdn.jsdelivr.net.
Attack narrative
Opening the SVG loads obfuscated JavaScript that fetches remote content and installs a remote transport client by adding a script element. This gives remotely hosted code a path to execute in the page context.
AI rationale
The package entry point is an SVG that loads heavily obfuscated JavaScript with remote-fetch behavior, and the page also injects a remote transport script. This is an active remote-code loading chain, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The manifest names index.svg as the entry point, and that document loads achroma.js.
- Obfuscated achroma.js fetches remote code and additional required resources.
- The page also loads a transport script from cdn.jsdelivr.net at runtime.
