Malware Insights
The PDF file was identified as malicious due to the presence of a PDF_MALICIOUS_REDIRECTOR_LINK heuristic, indicating a link to known malicious redirector infrastructure. Additionally, a PDF_SEO_LINK_FARM heuristic fired, revealing a large number of external PDF links within the document. One of these links, 'https://ttraff.cc/pify?keyword=first+aid+guide+wow+vanilla', is a known malicious redirector. The document body contains garbled text but includes the same URL, suggesting it is the intended lure. The file's purpose appears to be directing users to malicious content through a deceptive 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.
