T1204 Malicious Link
T1204.002 Malicious File
The file is identified as a malicious PDF by ClamAV with the signature Pdf.Exploit.Agent-22927. Static analysis indicates the presence of an embedded file and an XFA form, both common vectors for PDF exploits. The differential parser failure suggests obfuscation or a non-standard structure. The embedded file, 'embedded_file_obj0001.bin', is likely the secondary payload. The overall attack pattern points towards a PDF exploit designed to deliver further malware.
Heuristics 5
-
ClamAV: Pdf.Exploit.Agent-22927 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Agent-22927
-
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.
