Verdict Malicious
Is firmware_ upgrade_ utility. exe safe? No, we rate this exact file malicious.
Family labels are inconsistent and the sandbox verdict itself was clean, so the exact malware family remains unconfirmed despite the substantial risk.

If you already ran it, follow the steps below.
What to do now4 steps
This file is harmful. Don't run it, and remove it.
If you haven't run it
Don't run this file. Delete it, then empty the Recycle Bin.
If you already ran it
Disconnect the device from the internet, then run a full antivirus scan. Microsoft Defender Offline (Windows Security > Virus & threat protection > Scan options) also finds malware that hides while Windows runs.
If you typed passwords on the device after running it, change them from another device you trust.
If the scan keeps finding it, or the device still acts strangely, scan again with a second-opinion scanner from another company; if that doesn't fix it, back up your personal files and reinstall Windows.
If you already ran it, do these in order.

Why we think so
4 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Twenty-four of the 72 antivirus engines that checked it flagged the executable, representing 23 deduplicated detection votes and including four major detections. Microsoft named Wacatac, while Avast and AVG reported DangerousSig; because Avast and AVG share technology and the broader labels differ, there is no strong family consensus. The executable is unsigned and contains high-entropy code consistent with packing, which reinforces the detection evidence. The completed sandbox verdict was clean and the fully covered host-reputation check found no known harmful destinations, but those counter-signals do not adequately explain the process injection and broad engine response.
What We Detected
Twenty-four of the 72 antivirus engines that checked it flagged the executable, with 23 deduplicated detection votes. Microsoft reported Wacatac, Avast and AVG reported DangerousSig, and several other engines used Agent or generic trojan labels. The file has no verified publisher signature and contains a high-entropy UPX-style section consistent with packing.
Threat Behavior
The completed sandbox run recorded MITRE T1055 process injection into WMIADAP.EXE and T1560 archive-related behavior. It also observed USB and drive enumeration consistent with a firmware utility, so not every action is inherently hostile.
What To Do Now
Do not run the file on a production system or attach a device to it. Keep security software enabled, let your antivirus remove the executable, and obtain a fresh copy only from the hardware manufacturer's verified support channel before comparing hashes or signatures.
Where this verdict could be wrong3 caveats
- The completed reputation cross-check covered the observed hosts and found no cached malicious or suspicious destinations; several contacts were analysis-environment background traffic.
- Four dropped files lack saved verdicts, so they provide no corroborating file it created classification.
- Twelve major antivirus engines did not flag the file, and the four major detections do not establish a strong family consensus.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- The completed sandbox run returned a clean overall verdict.
- The complete observed-host reputation check found no known malicious or suspicious destinations.
- No inspected file it created has a saved harmful verdict.
- Twelve major antivirus engines did not flag the file.
- Twenty-four of the 72 antivirus engines that checked it flagged the executable, including four major detections.
- The executable is unsigned and lacks an established publisher history.
- High-entropy executable code indicates packing or substantial code concealment.
- Engine labels include Wacatac, DangerousSig, Agent, and generic trojan classifications.

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: Checked whether it was running on a test computer.
Note: Listed the programs running on the test computer.
Note: Talked to servers over the internet during the test run.
Note: Read basic details of the test computer, such as its Windows version.
Note: Looked through folders on the test computer (most installers do this).
Note: Checked which security software was installed on the test computer.
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 spreading through USB drives; nothing confirms it.
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.
Threat context
How trojans work
A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

24 of 72 engines flagged this file
4 of the 76 engines returned no result for this file (file type not supported, or the scan did not finish), so they did not check it.
The 24 detections come from 22 independent scan engines: several vendors license the same engine, so their results are one vote.

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
EvidenceT1055 (sandbox MITRE mapping)PE is packed (high-entropy code or known packer) AND unsigned AND at least one engine flagged it. Packing alone is common in legit software; packing + unsigned + signal is the malware-dropper pattern.
Evidencepackers: UPX (section names)Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.
Evidence23.54.127.209
Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Moderate prevalence — neither rare nor common. No strong prior applies.
