AI Security Review
scanned 4mo ago · by lpm-firewall-aiDespite benign/authorized claims, the source implements unconsented install-time reconnaissance and outbound exfiltration as a dependency-confusion proof of execution. That is concrete attack behavior for an upstream firewall and should be blocked.
Decision evidence
public snapshot- package.json runs preinstall and postinstall: node callback.js <phase>.
- callback.js sends install-time DNS, HTTPS, and HTTP beacons to 4li9yfz7.instances.httpworkbench.com.
- callback.js collects hostname, username, cwd, __dirname, platform, internal IPv4s, npm registry, timestamp.
- INSTRUCTIONS.md describes version 99.0.0 as high to win dependency resolution and confirm dependency confusion.
- INSTRUCTIONS.md says webhook hits mapping to Accesso build/CI infra confirm dependency confusion.
- index.js exports only validString with no runtime side effects.
- No child_process, eval/vm/Function, persistence, destructive writes, or credential file reads found.
- README.md and comments claim authorized bug-bounty PoC, but source still performs unconsented install-time telemetry.
