Is zzz-mod-fixer-v3.1.exe safe?
Unsigned executable with one tier-1 detection and sandbox evidence of process injection plus LSASS access.
4 of 75 engines flagged the file, including one tier-1 engine. Sandbox recorded process-injection and LSASS-access activity, yet no family consensus or malicious children were found.

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.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
4 of 75 engines flagged the file, including one tier-1 engine. Sandbox recorded process-injection and LSASS-access activity, yet no family consensus or malicious children were found.
The single tier-1 detection paired with two offensive MITRE techniques raises concern, but the absence of family consensus, unsigned status, and clean external-intel results keep the file in mixed-signals territory. Rarity and lack of prior samples prevent a clean verdict. Host-reputation data is unavailable, so network behaviour cannot be fully assessed.
What We Detected
One tier-1 engine (Microsoft) labelled the sample Trojan:Win32/Wacatac.B!ml; three low-trust engines also flagged it. Sandbox execution showed T1055 process injection and T1486 data-encryption behaviour plus LSASS memory access.
Threat Behavior
The file wrote multiple temporary assets and contacted a single external IP with no domain recorded. No dropped children were flagged malicious, and external-intel sources returned no hits.
What To Do Now
Do not execute the file on production systems. Keep endpoint protection enabled and submit the sample to a sandbox for deeper behavioural review before any further use.
Where this verdict could be wrong1 caveat
- engines.tier1Malicious=1 with no family consensus and 16 tier-1 clean detections; low-trust detections may be heuristic noise.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No tier-1 family consensus
- No malicious dropped children
- External intel clean
- Unsigned executable
- Process-injection technique observed
- LSASS access observed
- Rare and newly submitted
Treat as suspicious; run only in an isolated environment and monitor for further indicators before trusting the file.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
EvidenceC:\Windows\System32\svchost.exe -k NetworkService -pSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

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