MT AI Engine · Verdict analysis

The reasoning behind this verdict

The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.

95%Confidence
Very high
Reasoning

The file 'WMMA5.exe' is a known component of a commercial game. The low-trust engine detections are typical for unsigned game patches that perform network checks. There is no evidence of malicious behavior, and the file's activity is consistent with documented update processes. We have classified this as safe based on the lack of tier-1 consensus and the availability of official developer documentation regarding these specific security triggers.

Key signals · 4

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

  1. 0/17 tier-1 engines flagged the file, indicating no consensus among high-trust security vendors.

  2. 3/75 engines flagged the file with generic low-trust labels, consistent with 'ai:low_trust_engines_only' false-positive patterns.

  3. Official support forums at greydogsoftware.com confirm 'WMMA5.exe' is a legitimate game patch that frequently triggers security software.

  4. The 'MalwareTips.Synth.DirectIpC2' heuristic is a known artifact of the game's update mechanism, as documented in official support threads.

Points in its favour
  • No tier-1 engine detections
  • Documented benign behavior in official support forums
  • Generic low-trust engine labels
Points against
  • Unsigned executable
Recommended action

The file is safe. If blocked, add an exclusion in your security software as recommended by the developer.

Safety FAQ

Common questions about WMMA5.exe, answered from the scan data above.

  • WMMA5.exe appears safe. 72 of 75 antivirus engines report it clean, with only 3 low-confidence detections that read as false positives. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
  • WMMA5.exe is a Windows executable program, about 55.6 MB. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 3 of 75 antivirus engines flagged WMMA5.exe, 3 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
  • The SHA-256 hash of WMMA5.exe is ba79c03065b44e6f2699c35064ccf4d6c07a68fba99822dc57d739c4f728d8b6, and its MD5 is 9568b56fab71a048e6fd309e4fdcd910. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
  • Based on this scan, yes — WMMA5.exe shows no threat indicators. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
  • This report reflects the scan run on July 19, 2026. Because a file's hash never changes, the identity of WMMA5.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.

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.
