The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

Reasoning

The complete absence of malicious detections across tier-1 and tier-2 engines, combined with no sandbox verdicts or external-intel hits, indicates no malware indicators. The file type (package-lock.json) is a standard Node.js artifact that antivirus engines rarely flag. While the rare_new classification and lack of signing history limit long-term reputation data, nothing in the payload suggests malicious intent or behaviour.

Key signals · 4

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. engines.malicious=0 with tier1Malicious=0 across 61 reporting engines

  2. prevalence.classification=rare_new (1 submission, 0 days old)

  3. signing.verified=null (unsigned) with signerStats.found=false

  4. externalIntel.yaraify.ruleCount=0 and circl.knownMalicious=null

Points in its favour
  • Zero malicious engine detections
  • No behavioural or network indicators
  • No external intelligence matches
What to do

Treat as a clean package-lock.json file; no further action required unless the file is modified or sourced from an untrusted location.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
