T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a large number of embedded links, many of which point to a redirector service at 'ttraff.ru'. The document body text, though heavily obfuscated, contains the string "Spring boot tutorial point pdf", likely intended as a lure. The primary malicious URL identified is https://ttraff.ru/pify?keyword=spring+boot+tutorial+point+pdf, which is flagged as a malicious redirector. The document also contains a mass external PDF link farm, with many links pointing to benign Shopify-hosted PDFs, likely to improve SEO and disguise malicious intent.
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.
