Is 50MM ç¾æ éé³é¨æ£éªæ¥åï¼è±æç).pdf safe?
No antivirus engine detected malware in this encrypted PDF, although its very recent appearance and lack of runtime analysis warrant ordinary document precautions.
All 75 antivirus engines returned no malware or suspicious detection, including 17 tier-1 engines. No external-intelligence match or offensive technique was identified, but the PDF is encrypted, newly observed, and was not examined in a completed sandbox run.

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 malware or suspicious detection, including 17 tier-1 engines. No external-intelligence match or offensive technique was identified, but the PDF is encrypted, newly observed, and was not examined in a completed sandbox run.
The strongest evidence is unanimous static scanning: 0 of 75 engines flagged the document, and all 17 tier-1 engines that evaluated it reported no detection. CIRCL, MalwareBazaar, and YARAify supplied no corroborating malware intelligence. No offensive MITRE technique, malicious child, or malicious sandbox verdict appears in the evidence. However, behaviour.sandboxCount=0 means runtime behavior was not observed, and contactedHosts is unavailable rather than clean. The document's encryption and single recent submission lower confidence modestly but do not outweigh the broad absence of detections.
What We Detected
The 2,675,097-byte encrypted PDF received 0 malicious and 0 suspicious detections from 75 antivirus engines. All 17 tier-1 engines, including BitDefender, Kaspersky, ESET-NOD32, and Microsoft, reported no detection. CIRCL, MalwareBazaar, and YARAify produced no matching intelligence.
Threat Behavior
No offensive MITRE techniques, malicious dropped children, or malicious sandbox verdicts were recorded. However, no completed sandbox run is available, so runtime behavior cannot be characterized. The contacted-host cross-check was not saved, and therefore no complete host-reputation conclusion is available.
What To Do Now
The evidence does not indicate malware, but the document is encrypted and newly observed. Open it only if its source and purpose are expected, use an updated PDF reader, keep endpoint protection enabled, and avoid following unexpected links or enabling embedded content.
Where this verdict could be wrong3 caveats
- The PDF is encrypted and was submitted only once on its first observed day, limiting historical and content-level assurance.
- behaviour.sandboxCount=0 means no runtime execution was completed.
- contactedHosts=null, so no complete host-reputation result is available; however, no runtime contacts were observed because no sandbox run completed.
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 and engines.tier1Malicious=0.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false.
- behaviour.offensiveCount=0.
- similarHashes contains 5/5 prior safe file-type matches.
- file.tags includes 'encrypted', which can limit content inspection.
- prevalence.uniqueSources=1 and prevalence.timesSubmitted=1 indicate minimal history.
- behaviour.sandboxCount=0 leaves runtime behavior unobserved.
- contactedHosts=null means no complete host-reputation result is available.
The document may be opened with an updated, hardened PDF reader if it came from an expected source. Keep endpoint protection enabled and do not interact with unexpected links, attachments, or embedded prompts.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when its sender or download source is one you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
