MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
T1059.001 PowerShell
The PDF document employs a social engineering tactic, urging the user to install a browser extension or update to view its content. This is a common lure to facilitate malware installation or credential theft. The document contains a link to a known malicious redirector, https://ttraff.cc/pify?keyword=command+line+linux+pdf, which likely serves as the initial stage for delivering a secondary payload. The PDF also hosts a large number of external links, many pointing to benign Shopify URLs, suggesting a link farm for SEO manipulation or to obscure the malicious redirector.
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.
