The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

Very high
Reasoning

The file received unanimous clean verdicts from our highest-trust antivirus network, with zero malicious detections across 63 total engines. No tier-1 consensus family was identified, no heuristic rules fired, and external intelligence sources (CIRCL, YARAify, MalwareBazaar) returned no hits. The PDF format and large file size (13.4 MB) are consistent with a legitimate document archive. While the file is newly submitted (rare_new), the breadth and tier-level of clean detections strongly outweighs the novelty concern.

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. tier1ReportedClean=17 engines (Kaspersky, Microsoft, BitDefender, ESET-NOD32, Fortinet, Avast, AVG, Avira, DrWeb, Emsisoft, F-Secure, GData, Ikarus, all undetected)

  2. engines.malicious=0/63 reporting; tier1Malicious=0; onlyLowTrustFlagging=false

  3. File type: PDF (non-executable); unsigned; no PE analysis applicable

  4. prevalence.classification=rare_new (1 submission, 0 days old) — consistent with newly uploaded benign document

  5. externalIntel: CIRCL.hit=false, YARAify.ruleCount=0, MalwareBazaar.hit=false — no external corroboration of malicious activity

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.
