Verdict Suspicious

Analyzed , 1 month ago

Is AAD50.exe safe? Treat it as suspicious.

The executable lacks a verified publisher and produced runtime indicators associated with process injection and access to the Windows password store.

Read the whole reasonShow less

Why Suspicious? 4 antivirus engines flag it, but no major engine agrees; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

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

If it came from a link, an attachment or a stranger, delete it.

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 run 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 ran it

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

Not sure what to do?

Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Only 4 of the 70 antivirus engines that checked it detected it, none major, and the XWorm name appears in one smaller result, so the family attribution is not sufficiently corroborated.

Where this verdict could be wrong4 caveats
  • All 17 reporting major antivirus engines were undetected, and no major antivirus engines supplied an XWorm family detection.
  • No sandbox returned a malicious verdict, while no dropped file is known to be malicious across 10 inspected children; all child outcomes were actually unknown rather than confirmed clean.
  • The absence of community YARA matches, the absence of a known-software database match, and the absence of a MalwareBazaar listing provide no researcher-curated corroboration.
  • The five historical links are import-table fingerprint-only with signerMatchesSubject=false, so shared build or packaging components could explain the similarity.

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

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Moderate concern: Checked whether it was running on a test computer.

  • Note: Read the user name of the test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • Note: Read basic details of the test computer, such as its Windows version.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: Showed activity a sandbox rule links to file encryption; no ransomware behaviour was confirmed.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

How many antivirus engines detected AAD50.exe?
4 of the 70 antivirus engines that checked it flag AAD50.exe, including CrowdStrike and Zillya. We weigh which engines flagged it and what else the scan found, not just the count.
I already downloaded and ran AAD50.exe — what should I do?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of AAD50.exe?
The SHA-256 fingerprint of AAD50.exe is 51c367bd37c6e3f69e0495a86e340ee286864c7ec64cd7b2fbb127a8a8af40d1, and its MD5 is 9ca99a0ff49b65fccb38428ab54a2183. 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.
How up to date is this analysis of AAD50.exe?
This report reflects the scan on Sep 18, 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.
