MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was identified as malicious due to a critical heuristic firing for a PDF redirector link, which points to `https://ttraff.ru/pify?keyword=aayiram+kannumai+lyrics`. Additionally, another critical heuristic detected a PDF link farm, with numerous links pointing to Shopify domains, likely as a means to distribute malicious content or host phishing pages. The document body contains the text 'Aayiram kannumai lyrics' and references wkhtmltopdf, suggesting a lure document possibly related to song lyrics to mask the malicious redirection. No scripts were extracted from this sample.
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.
-
