MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1059.001 Command and Scripting Interpreter: PowerShell
T1204.002 Malicious Link
The PDF file contains a mass of external links, many pointing to Shopify-hosted PDFs, which is indicative of a link farm or SEO spam campaign. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is used to obscure the final destination. The document body also contains the URL "https://ttraff.cc/pify?keyword=mit+press+algorithms+pdf", suggesting a lure to trick users into clicking on malicious links under the guise of academic 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.
