T1059.001 PowerShell
T1204.002 Malicious Link
The PDF document contains a link farm designed to appear as a software download, specifically 'refx nexus 2 download crack zip'. This is a common lure to trick users into downloading malicious content. The presence of a critical heuristic for a malicious redirector link and a password-protected archive lure strongly suggests this document is part of a delivery chain. The document body, though heavily obfuscated, contains the primary malicious URL and several other PDF links, likely part of the link farm.
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.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.ru/pify?keyword=refx+nexus+2+download+crack+zip
