T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating a link to known malicious infrastructure. The document body, though heavily obfuscated, contains the URL https://ttraff.ru/wix?keyword=the+skeletal+system+worksheet+answer+key, which is presented as an answer key. This suggests a social engineering attack aiming to redirect users to a malicious site.
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.
-
