The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/pify?keyword=tumor+de+cervix+pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links to other PDFs, likely for SEO manipulation or to obscure malicious destinations. The presence of a visible LOLBin command execution instruction suggests the document is designed to execute commands or download further payloads. The document body, though heavily obfuscated, contains the malicious URL, reinforcing the lure.
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.
