MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous embedded links, with a critical heuristic identifying a malicious redirector. The document body, though heavily obfuscated, appears to reference 'Ssc steno syllabus 2020 pdf', suggesting a lure to disguise the malicious intent. The primary malicious URL identified is ttraff.ru, which is likely used to redirect users to a further stage of the attack. The presence of a large number of external PDF links, many hosted on Shopify, indicates a link farm strategy to distribute the malicious content.
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.
-
