Is !-SCPGT04.PDF safe?
No antivirus engine detected the established PDF, and its completed sandbox run produced no malicious assessment despite an uncorroborated credential-dumping technique mapping.
All 74 antivirus engines reported no detection, including 17 tier-1 engines, and the completed sandbox run returned a clean assessment. A heuristic mapped activity to credential dumping, but that isolated mapping lacks support from engines, known-bad hosts, dropped malware, persistence, or external research intelligence.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 antivirus engines reported no detection, including 17 tier-1 engines, and the completed sandbox run returned a clean assessment. A heuristic mapped activity to credential dumping, but that isolated mapping lacks support from engines, known-bad hosts, dropped malware, persistence, or external research intelligence.
The PDF received zero malicious or suspicious detections across 74 antivirus engines, with all 17 tier-1 participants reporting no detection. One completed sandbox run produced no malicious assessment, while the observed processes and written files primarily relate to Adobe Acrobat. Reputation checking found no malicious or suspicious entries for all five contacted domains, though the four recorded IP addresses were not explicitly covered by that host check. The T1003 and T1485 mappings are meaningful counter-signals, but they are unsupported by persistence, malicious children, external-intelligence matches, or engine detections. Its roughly six-year history and 80 submissions across 74 sources further reduce the likelihood that the isolated behavioural mapping represents active malware.
What We Detected
The PDF was not flagged by any of 74 antivirus engines. All 17 tier-1 engines that participated, including Avast, BitDefender, ESET-NOD32, Kaspersky, and Microsoft, reported no detection. External checks also returned no CIRCL, MalwareBazaar, or YARAify match.
Threat Behavior
One completed sandbox run returned a clean assessment and mainly showed Adobe Acrobat components, temporary files, and Adobe-related network activity. The five contacted domains were fully checked against the host cache with no malicious or suspicious matches; however, four separately recorded IP addresses were not explicitly covered. A heuristic mapped activity to MITRE T1003 and the report also lists T1485, but these mappings lack corroboration from the sandbox verdict, engines, persistence indicators, or known-bad infrastructure. Ten child hashes were inspected without a malicious result, although their individual classifications remain unknown.
What To Do Now
The evidence does not indicate an active payload. Keep endpoint protection enabled, open the document only in an updated PDF reader, and verify the document's source if it arrived unexpectedly or requests sensitive information.
Where this verdict could be wrong3 caveats
- triggeredHeuristics[0] cites MITRE T1003, and behaviour.offensiveTechniques also includes destructive technique T1485; neither mapping is independently corroborated.
- droppedChildren.rollup.unknown=10 means the ten inspected child hashes did not receive affirmative benign classifications.
- contactedHosts.inspected=5 covers the five domains but does not explicitly include the four entries in behaviour.contactedIps.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus engines detected a threat
- 17 tier-1 engines reported no detection
- Completed sandbox run returned a clean assessment
- All five contacted domains had no malicious or suspicious cache matches
- No CIRCL, MalwareBazaar, or YARAify hit
- MITRE T1003 credential-dumping mapping from one sandbox
- MITRE T1485 destructive-impact mapping without corroboration
- Ten observed child hashes remain individually unclassified
- Four contacted IP addresses lack explicit host-cache coverage
Keep security protection enabled and use an updated, sandboxed PDF reader. If the document came from an unexpected sender, confirm its origin before interacting with links or forms.
