MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file exhibits characteristics of a link farm, containing numerous external links. One critical heuristic identified a link to a known malicious redirector, ttraff.com, which likely serves as a lure. The document body, though heavily obfuscated, contains references to 'Drumbit chrome store' and the authoring application 'wkhtmltopdf', suggesting a potential attempt to disguise the malicious nature of the links. The presence of many links to static.usrfiles.com, while flagged as benign, contributes to the overall link farm characteristic.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
