MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass of external links, many of which point to Shopify domains hosting other PDFs, suggesting a link farm for SEO poisoning. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is further obfuscated by a query parameter related to 'bteb exam routine 2020 pdf download'. This indicates a social engineering lure to trick users into clicking the malicious link, likely leading to further malware delivery or phishing. No scripts were extracted from this sample.
Heuristics 4
-
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.
-

-
