PDF file with zero detections across 63 antivirus engines, including 17 tier-1 vendors; no malicious indicators.
a4029cfc20d5bef9f3…35374441a5The 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.
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.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
tier1ReportedClean=17 engines (Kaspersky, Microsoft, BitDefender, ESET-NOD32, Fortinet, Avast, AVG, Avira, DrWeb, Emsisoft, F-Secure, GData, Ikarus, all undetected)
engines.malicious=0/63 reporting; tier1Malicious=0; onlyLowTrustFlagging=false
File type: PDF (non-executable); unsigned; no PE analysis applicable
prevalence.classification=rare_new (1 submission, 0 days old) — consistent with newly uploaded benign document
externalIntel: CIRCL.hit=false, YARAify.ruleCount=0, MalwareBazaar.hit=false — no external corroboration of malicious activity
- 17 tier-1 antivirus engines reported clean (Kaspersky, Microsoft, BitDefender, ESET-NOD32, Fortinet, Avast, AVG, Avira, DrWeb, Emsisoft, F-Secure, GData, Ikarus)
