MITRE ATT&CK
T1204.001 Malicious Link
T1566.002 Spearphishing Attachment
The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.com', which is used in a social engineering lure to trick users into installing a browser extension. The document body and embedded links further support this by referencing 'Puffin browser pro apk free uptodown' and a large number of other PDF files, indicating a link farm designed to attract traffic. The primary intent appears to be driving users to malicious infrastructure via the 'ttraff.com' redirector.
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
-
