MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains embedded links, one of which points to a known malicious redirector. The document body, though heavily obfuscated, contains text related to 'chocolate' and 'hormones' which is likely a lure to entice users to click the malicious link. The presence of numerous external PDF links, many hosted on static.usrfiles.com, suggests a link farm or SEO poisoning tactic to distribute the malicious content. No scripts were extracted, but the primary attack vector appears to be social engineering via deceptive links.
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.ru/wix?keyword=o+chocolate+estimula+a+produ%25C3%25A7%25C3%25A3o+do+horm%25C3%25B4nio+2-feniletilamina
