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.

45%Confidence
Moderate
Reasoning

Zero malicious detections across tier-1 and tier-2 engines combined with an unsigned state and rare_new classification produce an inconclusive profile. The absence of sandbox behaviour, dropped children, or contacted hosts removes both malicious and benign behavioural anchors. Without prior similar-hash verdicts or signing history, the evidence does not support a confident safe or malicious call.

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. engines.malicious=0 and engines.tier1Malicious=0 across 58 reporting engines

  2. prevalence.classification=rare_new with file.ageDays=1

  3. signing.verified=false (unsigned) and similarHashes.length=0

  4. filenameAnalysis.looksLikePortable=true on ZIP archive

Points in its favour
  • Zero malicious detections
  • No adversarial filename flags
Points against
  • Unsigned file
  • rare_new prevalence
  • No sandbox or behavioural data
Recommended action

Quarantine the ZIP and request sandbox detonation or expanded engine coverage before any use.

What to do now

There isn't enough information to give this file a clear rating.

  1. Be cautious — an unknown rating is not the same as a clean bill of health.

  2. Only run it if it came directly from the official maker of the software.

  3. When in doubt, don't open it — or scan it again later once it's more widely seen.

How widely this file has been seen

Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ

Common questions about 43b2b46a-a031-46ad-a8a4-0da004500de7.zip, answered from the scan data above.

  • We can't give 43b2b46a-a031-46ad-a8a4-0da004500de7.zip a confident verdict yet — too few engines have an opinion on this exact file. Uncommon or brand-new files often show little coverage before vendors catch up, so treat it as untrusted: don't opened or extracted it unless you're certain of the source.
  • 43b2b46a-a031-46ad-a8a4-0da004500de7.zip is a compressed archive, about 3.7 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
  • None — all 73 antivirus engines we queried report 43b2b46a-a031-46ad-a8a4-0da004500de7.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 43b2b46a-a031-46ad-a8a4-0da004500de7.zip is fa4bb42248df1a52130e8be56d582f50e1ab0bdc25c23f6d9f7e828a1f4045a8, and its MD5 is 1eafccfc48eb1e70528e63d20d6c012a. 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.
  • This report reflects the scan run on July 8, 2026. Because a file's hash never changes, the identity of 43b2b46a-a031-46ad-a8a4-0da004500de7.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.
