MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.cc', which is further associated with a lure for 'Quickbooks 2015 download'. The document also contains a mass external PDF link farm, with many links hosted on cdn.shopify.com. The presence of these elements suggests a social engineering attack aimed at tricking users into clicking malicious links, likely for software piracy or malware distribution.
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.
