T1204.002 Malicious Link
The PDF contains multiple embedded links, with one identified as a malicious redirector. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' and 'PDF_SEO_LINK_FARM' indicate a pattern of linking to external, potentially harmful content. The presence of a 'SE_LOLBIN_RUN_COMMAND' heuristic suggests that the document may also contain instructions for executing commands, possibly to download or run further payloads. The primary malicious URL identified is https://ttraff.ru/pify?keyword=calendar+format+google+sheets.
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.
-
Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMANDDocument contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
