MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous embedded links, a common tactic for SEO poisoning or redirecting users to malicious sites. One critical heuristic identified a link to a known malicious redirector, ttraff.ru, which is presented in the document body with a keyword related to Cisco network images. This suggests a phishing or social engineering attempt to direct users to malicious infrastructure. The file also contains a large number of links to PDFs hosted on static.usrfiles.com, which is flagged as a link farm.
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.
