The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 engines returned clean results and no tier-1 or low-trust engine flagged the file. The file is a 12 MB e-book that has been submitted only three times since 2023 with no sandbox or host-contact data available.
Zero detections from 75 engines, including 18 tier-1 engines, combined with clean external-intel sources and no adversarial filename signals, indicate the file is benign. The low submission count is consistent with an older, niche e-book rather than malicious software. Absence of sandbox or contacted-host data is neutral and does not alter the conclusion.
What We Detected
3 antivirus engines scanned the file; none returned a malicious or suspicious result. External intelligence sources (CIRCL, MalwareBazaar, YARAify) also returned no matches.
Threat Behavior
No sandbox execution data or network-contact records are present. The file type is an e-book and shows no signs of executable code or installer behaviour.
What To Do Now
The file can be opened with any standard e-book reader. Keep endpoint protection enabled as a general precaution.
- Zero detections from 18 tier-1 engines
- No external-intel hits
- No adversarial filename or signing anomalies
Open the e-book with a trusted reader; no further security action is required.
