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.

85%Confidence
Very high
Reasoning

The complete lack of detections across tier-1 and tier-2 engines, combined with common_old prevalence and clean sandbox results, indicates a benign installer. The single heuristic on direct-IP contact is outweighed by the absence of any corroborating malicious signals and the file's established history.

Key signals · 5

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

  1. engines: 0 malicious detections out of 75 total (16 tier-1 clean)

  2. prevalence.classification=common_old (408 submitters since 2016-01-20)

  3. behaviour: hasMaliciousSandboxVerdict=false, droppedChildren.hasMaliciousChild=false

  4. triggeredHeuristics: MalwareTips.Synth.DirectIpC2 on IPs 204.79.197.203 and 23.10.195.101

  5. filenameAnalysis.hasInstallerHint=true

Points in its favour
  • Zero detections across 68 engines
  • Established prevalence since 2016
  • Clean sandbox behaviour
Recommended action

Treat as safe; the long history and complete lack of detections support benign classification.

    Sample contacted 2 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.

Safety FAQ

Common questions about visualsyslog_setup.zip, answered from the scan data above.

  • visualsyslog_setup.zip 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.
  • visualsyslog_setup.zip is a software installer, about 1.5 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 visualsyslog_setup.zip 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 visualsyslog_setup.zip is 9efbde364f2abfdcfd1f69ed536ebdc1daa37030e52085e0932557567bb8cd7f, and its MD5 is 9b512284cb420e97c7be57eeeb048a21. 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 — visualsyslog_setup.zip 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 visualsyslog_setup.zip 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.
