MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass of external links, many of which are hosted on Shopify and appear to be part of a link farm. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is used to obscure the final destination. The document body, though heavily obfuscated, contains the same URL and a reference to historical criminalistics, likely a lure to entice clicks. The presence of numerous PDF links suggests a campaign to distribute malicious content.
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.
