MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a link that redirects to a URL associated with malicious redirector infrastructure, specifically mentioning 'kaspersky antivirus security 2018 free' as a lure. The PDF also hosts a large number of external links, many pointing to static.usrfiles.com, suggesting a link farm or SEO poisoning tactic to attract victims. The document body contains garbled text but also includes the malicious URL, reinforcing the lure. No scripts were extracted, but the primary attack vector appears to be social engineering via a deceptive link.
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.cc/pify?keyword=kaspersky+antivirus+security+2018+free
