FINDINGS ░▒▓

what this code does░▒▓

What happens when you open, install or run it, from the findings below.

  1. when runlib/machine.js references browser profile paths, where saved logins and cookies live. lib/machine.js
  2. when runlib/rules/pack.js names a domain on scanrepo's list of hosts seen in malware. lib/rules/pack.js
  3. when runlib/whitebox/frameworks.js starts system processes. lib/whitebox/frameworks.js
  4. when runscripts/media/launch-figures.mjs and bench/public/competitors.mjs build code from strings at run time with eval. scripts/media/launch-figures.mjs, bench/public/competitors.mjs
  5. when runscripts/rules/sign-pack.sh and lib/agents/rules.js reference SSH key or cloud credential paths (such as ~/.ssh or ~/.aws/credentials). scripts/rules/sign-pack.sh, lib/agents/rules.js
  6. otherlib/rules/ioc-2025-2026/hosts.json and lib/rules/ioc-2025-2026/packages.json name a domain on scanrepo's list of hosts seen in malware. lib/rules/ioc-2025-2026/hosts.json, lib/rules/ioc-2025-2026/packages.json
  7. otherlib/rules/core/agent-instructions.json references SSH key or cloud credential paths (such as ~/.ssh or ~/.aws/credentials). lib/rules/core/agent-instructions.json

criticalRemote script piped into a shellA shell script downloads remote content and executes it directly (e.g. `curl … | bash`). The payload is never stored or reviewable and can change server-side — a classic malware/backdoor install pattern.tests/fixtures/agents/malicious/skills/helper/scripts/format.sh

Scores are heuristics. A “safe” verdict means no known-malicious patterns were found — clever malware can look boring. Wrong verdict? Flag it above; confirmed false positives become regression tests.
