T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/wix?keyword=descargar+labview+2017+64+bits+espa%25C3%25B1ol'. This URL is presented within the document body, disguised as a software download link. The document also contains a PDF link farm heuristic, indicating a large number of external links, with 'https://static.usrfiles.com/ugd/078c79_0a403456f13748a39d159b57a69727b4.pdf' being the first listed. The combination suggests a social engineering attempt to redirect users to malicious content.
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.
