MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous embedded links, many of which point to external PDF files hosted on Shopify. One critical heuristic firing indicates a link to a known malicious redirector, ttraff.com, which is likely intended to lead the user to a malicious site. The document body text, though heavily obfuscated, contains the string 'Linfoma burkitt pdf', suggesting a lure to disguise the malicious intent. The presence of a malicious redirector URL is the primary indicator of malicious activity.
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.
