Is TaskManager10000.exe safe?
Microsoft alone flagged this unsigned, newly observed executable with a generic Wacatac machine-learning label, while 74 of 75 engines provided no corroboration.
Microsoft reported a generic Wacatac machine-learning detection, but the other 74 of 75 engines did not corroborate it and no family consensus exists. Because the executable is unsigned, newly observed, and lacks completed runtime analysis, it should remain quarantined until its source or behavior can be verified.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Microsoft reported a generic Wacatac machine-learning detection, but the other 74 of 75 engines did not corroborate it and no family consensus exists. Because the executable is unsigned, newly observed, and lacks completed runtime analysis, it should remain quarantined until its source or behavior can be verified.
Only 1 of 75 engines detected the file, although that detection came from Microsoft, a high-trust engine. The Wacatac label is generic and has no support from another engine, researcher rule, known malware repository entry, or suspicious packing evidence. At the same time, this is an unsigned executable seen from only one source on its first submission, so there is little provenance supporting a benign interpretation. No completed sandbox observation exists, and no complete reputation check of contacted hosts is available. The five prior safe matches are based only on broad file-type similarity to unrelated files and therefore do not materially reduce the uncertainty.
What We Detected
Microsoft flagged the executable as Trojan:Win32/Wacatac.B!ml. It was the only detection among 75 engines, and there was no agreement on a named malware family.
Threat Behavior
No completed sandbox observation is available, so execution behavior cannot be characterized. The file is not evidently packed and its code sections do not show unusually high entropy, but those static properties do not prove benign intent. A complete reputation result for any contacted hosts is also unavailable.
What To Do Now
Keep the file quarantined and do not run it on a production system. Verify that it came from the official developer or expected distribution channel, and consider a controlled sandbox run or a fresh rescan after more engines have analyzed this newly observed sample.
Where this verdict could be wrong3 caveats
- Microsoft is a tier-1 engine and reported Trojan:Win32/Wacatac.B!ml, so its lone detection should not be dismissed despite lacking corroboration.
- Sixteen other tier-1 engines reported no detection, and no engine consensus identified a malware family.
- The executable is unsigned and newly observed from only one source, limiting confidence in a benign explanation.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1/75 engines reported a detection
- No tier-1 family consensus
- MalwareBazaar returned no hit
- YARAify returned zero matching rules
- peAnalysis.likelyPacked=false and highEntropyCode=false
- Microsoft tier-1 detection: Trojan:Win32/Wacatac.B!ml
- Unsigned Windows executable
- First observed at the current submission
- Only one known source and one submission
- No completed runtime analysis
- No complete contacted-host reputation result
Keep protection enabled and leave the file quarantined until its publisher and download source are verified. If it must be evaluated, use an isolated sandbox rather than a normal workstation.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. 1 antivirus detection make that low prevalence materially relevant, but rarity alone is not proof of malware.
