T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a large number of links, many of which point to a redirector service. The primary malicious URL identified is https://ttraff.cc/wix?keyword=parallel+circuit+calculations+worksheet, which is likely used to direct users to a malicious site. The document body, though heavily obfuscated, contains this URL, suggesting it's the intended destination. The presence of numerous PDF links indicates a link farm strategy, likely for SEO poisoning or to obscure the final malicious destination.
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.
