Is De animales a dioses - YUVAL NOAH HARARI.pdf safe?
No antivirus engine detected this established PDF, and its completed sandbox run produced neither offensive MITRE techniques nor a malicious runtime assessment.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 engines. One completed sandbox run produced no offensive MITRE techniques or malicious assessment, while independent intelligence checks supplied no malware corroboration.

Keep normal device protection enabled and stop if the file behaves unexpectedly.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 engines. One completed sandbox run produced no offensive MITRE techniques or malicious assessment, while independent intelligence checks supplied no malware corroboration.
The strongest evidence is unanimous antivirus silence: 0 of 75 engines flagged the PDF, and all 17 reporting tier-1 engines returned no detection. A completed sandbox run recorded no offensive MITRE techniques and no malicious sandbox assessment. No malicious child hash, persistence indicator, or observed network contact was recorded. Research intelligence checks produced no matching YARA rules, known-malicious reference, or malware-repository entry. Although several generic environment-awareness tags appear, they lack independent behavioural or detection corroboration.
What We Detected
None of the 75 antivirus engines flagged the PDF as malicious or suspicious. This includes 17 tier-1 engines, and no engine supplied a malware-family label.
Threat Behavior
One completed sandbox run produced no offensive MITRE techniques, persistence indicators, observed network contacts, or malicious assessment. Generic tags concerning timing and environment checks are present, but they were not corroborated by malicious runtime activity. No complete host-reputation result is available because contactedHosts was not saved, though the run recorded no contacted domains, IP addresses, or URLs.
What To Do Now
The evidence supports opening the document with a fully updated PDF reader while keeping endpoint protection enabled. Obtain documents from a trusted source and avoid enabling embedded content or following unexpected links if the reader presents a warning.
Where this verdict could be wrong2 caveats
- file.tags includes checks-network-adapters, long-sleeps, direct-cpu-clock-access, and detect-debug-environment, but no offensive MITRE technique or malicious sandbox verdict corroborates those tags.
- contactedHosts=null, so no complete host-reputation cross-check is available; however, behaviour.contactedDomains, behaviour.contactedIps, and behaviour.contactedUrls are all empty.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 engines reported a malicious or suspicious result.
- engines.tier1ReportedClean=17 with engines.tier1Malicious=0.
- behaviour.hasMaliciousSandboxVerdict=false and behaviour.offensiveCount=0.
- externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false.
- file.ageDays=1625 with 13 submissions from 12 sources.
- Generic file.tags include long-sleeps, checks-network-adapters, direct-cpu-clock-access, and detect-debug-environment.
- contactedHosts=null, so a separate host-reputation cross-check was unavailable.
The document can be opened with an updated PDF reader from a trusted source. Keep endpoint protection enabled and decline unexpected prompts for embedded content, downloads, or external links.
