MITRE ATT&CK
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF file contains a fake CAPTCHA prompt, a common social engineering tactic to trick users into interacting with malicious content. It also includes numerous links, with one pointing to a known malicious redirector at 'ttraff.ru'. This redirector is likely used to funnel victims to further malicious sites or downloads. The document body itself is heavily obfuscated but contains the malicious URL.
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.
-
