T1204.002 Malicious File
The PDF contains a mass external link farm, with many links pointing to PDF files hosted on Shopify. One critical heuristic indicates a malicious redirector link, specifically 'https://ttraff.cc/pify?keyword=acetylene+sds+pdf', which is likely used to obscure the final malicious destination. The document also employs a social engineering lure, instructing the user to install a browser extension or update to view content, a common tactic for credential theft or malware installation. No scripts were extracted from this sample.
Heuristics 4
-
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.
-
Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
