🤖 AI Analysis

Final verdict: SUSPICIOUS

The package exhibits signs of potential obfuscation and shell execution, raising concerns about its legitimacy and purpose. Additionally, it appears to be a typosquatting attempt targeting a similar named package.

  • High obfuscation risk due to hex-encoded strings
  • Potential typosquatting targeting 'arq'
Per-check LLM notes
  • Network: No network calls detected, which is normal and not indicative of malicious activity.
  • Shell: Shell execution is present and appears to be configuring system services, which may be expected behavior for a service-oriented package like 'arwn', but requires further investigation into the package's legitimate use case.
  • Obfuscation: The use of hex-encoded strings suggests potential obfuscation to hide the true purpose of the data being sent.
  • Credentials: No clear patterns indicating credential harvesting were found.
  • Metadata: The package shows some potential red flags but lacks concrete evidence of malice.
  • ⚠ Typosquatting target: arq
