MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, many pointing to Shopify domains, which is indicative of a link farm designed to manipulate search engine results or obscure malicious destinations. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is part of the attack chain. The document body, though heavily obfuscated, contains text related to 'assessment center exercises pdf', likely a lure to entice users to click the embedded links.
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.
