MITRE ATT&CK
T1204.002 Malicious Link
T1566.002 Spearphishing Link
The PDF contains a lure related to a 'video er pro extension chrome' and embeds multiple links. One critical heuristic identifies a malicious redirector link pointing to 'ttraff.club', which is likely used to host or redirect to malicious payloads. Another heuristic indicates a PDF link farm, with many links pointing to Shopify domains, but the primary malicious intent appears to be the redirector. The document body, though heavily obfuscated, contains the malicious URL and other Shopify URLs, reinforcing the social engineering aspect.
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
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.club/wix?keyword=video+er+pro+extension+chrome
