T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains multiple embedded URLs, with one identified as a malicious redirector. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms this, pointing to 'https://ttraff.cc/pify?keyword=mechanism+of+antioxidant+defence+system+pdf'. Additionally, the 'PDF_SEO_LINK_FARM' heuristic indicates a large number of links to other PDFs, likely for SEO manipulation or to obscure the malicious redirector. The presence of 'SE_LOLBIN_RUN_COMMAND' suggests that the document may also contain instructions for executing commands, potentially to download further payloads.
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
-
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.cc/pify?keyword=mechanism+of+antioxidant+defence+system+pdf
