T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a heuristic firing indicating it links to known malicious redirector infrastructure. It also contains a link farm of numerous external PDF links, many hosted on Shopify, with the primary redirector URL being 'https://ttraff.cc/pify?keyword=android+firewall+apk+full'. The document body, though heavily obfuscated, contains references to 'Android firewall apk full' and the redirector URL, suggesting a lure to download potentially malicious software. The presence of a large number of external PDF links suggests an attempt to manipulate search engine results or distribute content widely.
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.
-
