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 sample is a signed executable that functions as a self-extracting archive. Although it triggered high-severity heuristic rules, these are common in installers that perform file extraction and system configuration. The absence of any tier-1 engine detections and the lack of malicious activity in the sandbox environment strongly suggest that the heuristic alerts are false positives. The file's prevalence and signer information are consistent with legitimate, albeit niche, software distribution.

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. 1/69 engines flagged the file (VBA32), with 0/17 tier-1 engines reporting malicious (engines.tier1Malicious=0)

  2. Signed by 'Open Text Corporation' (signing.signer=Open Text Corporation), though not on the curated trusted publisher list

  3. Sandbox observed MITRE T1055 and direct-IP communication (behaviour.contactedIps=162.159.36.2), which are common in complex installers

  4. No malicious children detected across 10 inspected files (droppedChildren.hasMaliciousChild=false)

  5. Prevalence is medium (prevalence.classification=medium) with 36 submissions, suggesting it is not a highly targeted or rare threat

Points in its favour
  • 0/17 tier-1 engines flagged as malicious
  • Signed by a known corporation
  • No malicious children dropped
  • No malicious hosts contacted
Points against
  • T1055 (Process Injection) observed in sandbox
  • Direct-IP communication detected
  • High entropy in sections
Recommended action

The file is likely safe to use. Ensure it was downloaded from the official vendor website to maintain software integrity.

  • 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 1 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 7zS.sfx.exe, answered from the scan data above.

  • 7zS.sfx.exe appears safe. 73 of 74 antivirus engines report it clean, with only 1 low-confidence detection that read as false positives. It carries a verified digital signature from Open Text Corporation. 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.
  • 7zS.sfx.exe is a Windows executable program, about 25.1 MB. Our analysis found no threat indicators for it. It carries a verified digital signature from Open Text Corporation. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 1 of 74 antivirus engines flagged 7zS.sfx.exe, 1 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.
  • Yes — 7zS.sfx.exe carries a valid digital signature from Open Text Corporation, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
  • The SHA-256 hash of 7zS.sfx.exe is 4ea96add29557789561f8090ec534d35a424827f4b217b503e609dad8b17f8c5, and its MD5 is 478fec98c60e97ea98beed44d117b280. 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 — 7zS.sfx.exe shows no threat indicators and is properly signed. 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 7zS.sfx.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.
