MITRE ATT&CK
T1059.001 PowerShell
T1566.001 Spearphishing Attachment
The PDF file exhibits characteristics of malicious intent, including the presence of an embedded file and the use of obfuscated object names detected by ClamAV. The differential parser failure further suggests an attempt to evade analysis. While no specific document body text or scripts were provided for detailed analysis, the embedded artifact and heuristic detections strongly suggest a malicious payload delivery mechanism.
Heuristics 5
-
ClamAV: Heuristics.PDF.ObfuscatedNameObject critical CLAMAV_DETECTIONClamAV detected this file as malware: Heuristics.PDF.ObfuscatedNameObject
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILEDThe cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSSyntaxError. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
