MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF file contains a link to a known malicious redirector, ttraff.cc, disguised with a "brain teaser" lure. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms this malicious intent. Additionally, the PDF exhibits characteristics of a link farm, with numerous embedded links, many pointing to Shopify domains, suggesting an attempt to manipulate search engine results or distribute content broadly. The primary IOC is the malicious redirector URL.
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.
-
