The reasoning behind this verdict

Analyst conclusion

None of the 54 antivirus engines that checked it flagged this JavaScript file, and our static analysis found no obfuscation, hidden commands or malicious patterns. It does contain code that downloads content, which is common in web applications. The file is new and rarely seen, and it was not run in a sandbox.

Where this verdict could be wrong1 caveat
  • The script contains code that downloads content, and no sandbox run observed what it actually fetches; freshly written malicious scripts are sometimes missed by engines.

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 app.js safe?
We found nothing harmful in app.js. None of the 54 antivirus engines that checked it flag it. Run it only if it came from the developer's own website or an official app store.
What is app.js?
app.js is a JavaScript file, about 350.0 kB. VirusTotal first saw it on Oct 19, 2026.
How many antivirus engines detected app.js?
None of the 54 antivirus engines that checked it flag app.js. 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 app.js?
The SHA-256 fingerprint of app.js is f15796e0ad21b862ca7dcf71ba2dc4421e810c3c849ff14137de6cb5a858de63, and its MD5 is 36560e3b1a9aced0915d3c548dcdf6ec. 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 run app.js?
We found nothing harmful in app.js. 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 app.js?
This report reflects the scan on Oct 19, 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 To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
