MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous embedded links, many of which point to a redirector service (ttraff.ru) that is flagged as malicious. The document body and embedded links suggest a lure related to saving web pages to PDF on Android, likely intended to trick users into visiting malicious sites. The presence of a large number of external links, many hosted on Shopify, indicates a link farm or SEO poisoning attempt to drive traffic to the malicious redirector.
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.
