MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a malicious redirector link disguised as an invoice. The document body, though heavily obfuscated, contains the text 'Bsf ka form 2019' and the malicious URL 'https://ttraff.cc/pify?keyword=bsf+ka+form+2019'. This URL is flagged as a known malicious redirector. The PDF also contains a large number of external links, many hosted on Shopify, which is indicative of a link farm used for SEO poisoning or distributing malicious content.
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.
-
