The reasoning behind this verdict

Analyst conclusion

The file is unsigned and with no sandbox, network, or file it created activity recorded.

Where this verdict could be wrong1 caveat
  • JSON package-lock files are not typically scanned by AV engines, so zero detections may simply indicate the file type falls outside normal malware signatures.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is package-lock.json safe?
We found nothing harmful in package-lock.json. None of the 60 antivirus engines that checked it flag it. Open it only if you trust the person or website it came from.
What is package-lock.json?
package-lock.json is a file, about 319.1 kB. VirusTotal first saw it on Jul 10, 2026.
How many antivirus engines detected package-lock.json?
None of the 60 antivirus engines that checked it flag package-lock.json. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of package-lock.json?
The SHA-256 fingerprint of package-lock.json is 518499bde396f1d93f028e985fb247f676216af3b6ef5394474c07bf8727bf6b, and its MD5 is 27f0bc8838c9c2ed3eb9e00f29a5f621. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to open package-lock.json?
We found nothing harmful in package-lock.json. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of package-lock.json?
This report reflects the scan on Jul 10, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
