T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link, directing users to 'https://ttraff.cc/wix?keyword=berliner+platz+einstiegskurs+pdf'. This URL is likely used for phishing or to serve further malicious content. The document body, though heavily garbled, contains the same URL and text suggesting a lure related to a language course PDF. The presence of a large number of external PDF links, while many are benign, indicates a link farm strategy, potentially to improve SEO for malicious content or to obscure the primary malicious 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.
