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.

82%Confidence
High
Reasoning

The complete absence of malicious engine detections across all tiers combined with zero offensive MITRE techniques and no sandbox or network indicators supports a clean classification. Lack of signing and limited prevalence are noted but do not override the strong negative signals from the engines and behaviour data.

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.

Points in its favour
  • Zero malicious engine detections
  • No offensive MITRE techniques
  • No sandbox or external-intel hits
Recommended action

Treat as clean; no further action required unless new evidence emerges.

Safety FAQ

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

  • gbak.exe appears safe. 75 of 75 antivirus engines report it clean. 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.
  • gbak.exe is a Windows executable program, about 1 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).
  • None — all 75 antivirus engines we queried report gbak.exe as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
  • The SHA-256 hash of gbak.exe is ca86d68d6db51e992d64f2d61df7eac7bf58388db4872cc282d247a60942baa8, and its MD5 is e4762f74176e7a639cdca2ca9d318788. 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 — gbak.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 17, 2026. Because a file's hash never changes, the identity of gbak.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.
