Verdict Suspicious

Analyzed , 9 days ago

Is jpeg_wrapper.dll safe? Treat it as suspicious.

An Adobe-named JPEG library with an invalid signature and one Microsoft machine-learning trojan detection out of 75 engines.

Read the whole reasonShow less

Why Suspicious? One antivirus engine (Microsoft) flags it; nothing else confirms it.

Limited evidence

Don't use it until you know where it came from

Do not run or keep this DLL unless it came from an official Adobe install. Reinstalling the Adobe product from Adobe's site is the safest way to restore a genuine copy.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't use it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already used it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

The reasoning behind this verdict

Analyst conclusion

Only Microsoft flagged this DLL, out of 75 engines, using a machine-learning label. One sandbox run showed nothing harmful. However, its Adobe signature does not validate, so we cannot confirm it is genuine Adobe code.

Where this verdict could be wrong2 caveats
  • The invalid signature may come from file modification or truncation of a genuine Adobe library rather than tampering. The structure and exports look like an ordinary JPEG codec, and 16 of 17 major antivirus engines did not flag it.
  • Microsoft's '!cl' suffix indicates a cloud machine-learning detection, and these often produce false positives on large legitimate libraries.

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