T1059.003 Windows Command Shell
T1204.002 Malicious File
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.ru/pify?keyword=yahoo+finance++apk'. Additionally, it exhibits a PDF link farm and a lure for browser extension installation, indicating a social engineering attempt. The presence of a visible LOLBin command execution instruction further suggests malicious intent, likely to download and execute a second-stage payload. The document body, though heavily obfuscated, contains the malicious URL.
Heuristics 5
-
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.
-
