T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The PDF sample contains an embedded file and triggers heuristics related to XFA forms and exploits. ClamAV detection specifically identifies it as exploiting CVE-2010-0188, a known vulnerability in Adobe Reader. This suggests the primary attack pattern is exploitation for client execution, likely delivered via spearphishing.
Machine Learning
- Nyx PDF Classifier malicious score 1.0000
Heuristics 3
-
Suspicious extracted artifact high 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.
-
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
