MITRE ATT&CK
T1204.002 Malicious File: User Execution
T1566.001 Phishing: Spearphishing Attachment
The sample is a PDF file that utilizes XFA forms and the ASCII85Decode filter, both of which are indicators of potentially malicious content. Crucially, the critical heuristic firing for CVE-2010-0188 confirms the presence of an exploit targeting Adobe Reader's LibTIFF component. This exploit is embedded within an XFA image/tif payload, strongly suggesting the document is designed to execute arbitrary code upon opening in a vulnerable reader.
Heuristics 4
-
Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
