MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.ru/pify?keyword=basic+ms+office+course+pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous external links, many hosted on Shopify. The document body, though heavily obfuscated, contains the same redirector URL and a reference to 'basic ms office course pdf', suggesting a lure for users seeking educational material. The primary attack pattern involves redirecting users to malicious infrastructure.
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.
