T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious File
T1059.001 PowerShell
The PDF file contains numerous links, including one pointing to a known malicious redirector. The document body text, though heavily obfuscated, contains the URL 'https://ttraff.ru/wix?keyword=video+er+for+facebook+apk+no+ads', which is associated with malicious redirector infrastructure. The heuristic 'SE_BROWSER_INSTALL_LURE' indicates the document's intent is to trick the user into installing a malicious browser extension or update. The presence of a large number of external PDF links also suggests a link farm for SEO manipulation, potentially to drive traffic to malicious sites.
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.ru/wix?keyword=video+er+for+facebook+apk+no+ads
