MT AI Engine · our arbiter

The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

30%Confidence
Exploratory
Reasoning

Our AI analyst is temporarily unavailable. Based on the raw antivirus data we have (2 malicious of 71 reporting engines), we can't commit to a verdict confidently — re-scan in a few minutes for the full AI assessment.

Key signals · 3

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. AI arbiter unavailable (reason: grok_exception:This operation was aborted)

  2. engines.tier1Malicious=0

  3. engines.reporting=71

What to do

Wait a few minutes and re-scan for the full AI assessment before deciding.

  • ProcessInjectionhigh

    MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.

    Evidence
    "C:\Users\<USER>\Desktop\file.exe"
  • DirectIpC2medium

    Sample contacted 18 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
