MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature Win.Trojan.Agent-36166. Static analysis revealed embedded JavaScript, indicating a potential for malicious code execution. The JavaScript stream is likely responsible for downloading and executing a second-stage payload, which is a common technique for malware delivery. The PDF structure also shows signs of manipulation, with the differential parser failing.

Heuristics 5

ClamAV: Win.Trojan.Agent-36166 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Win.Trojan.Agent-36166
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED

The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSEOF. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
