Is VyrionUpdater.dll safe?
Two tier-1 engines flag a brand-new unsigned DLL with no prior history or sandbox data.
Microsoft and Symantec both detect the file as malicious, yet the sample is unsigned, first-seen today, and lacks sandbox or external-intel corroboration. The combination of two high-trust detections on a rare_new file places it in mixed-signals territory.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Microsoft and Symantec both detect the file as malicious, yet the sample is unsigned, first-seen today, and lacks sandbox or external-intel corroboration. The combination of two high-trust detections on a rare_new file places it in mixed-signals territory.
Two independent tier-1 engines returned named or high-confidence malicious labels, outweighing the single low-confidence tier-2 detection. The file is unsigned and has zero prior reputation, which prevents a clean verdict. Absence of sandbox results and external-intel hits leaves no runtime confirmation, so the evidence remains borderline rather than decisive.
What We Detected
Two tier-1 engines (Microsoft, Symantec) flagged the 5.4 MB DLL; Microsoft labels it Trojan:Win32/Wacatac.B!ml while Symantec reports ML.Attribute.HighConfidence. No other engines raised alerts, and no YARA, CIRCL, or MalwareBazaar hits exist.
Threat Behavior
No sandbox execution data or contacted-host reputation is available. The file is unsigned and first seen today, so no historical behaviour patterns can be assessed.
What To Do Now
Keep the file quarantined until additional sandbox or reputation data becomes available. Do not run or distribute it.
- Unsigned executable
- Rare and first-seen today
- Tier-1 malicious detections present
Treat the DLL as potentially malicious and block execution until further evidence clarifies its intent.

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. 3 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
