T1204.001 Malicious Link
T1204.002 User Execution: Malicious File
The PDF document contains a heuristic firing for a malicious redirector link pointing to 'ttraff.com'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, many hosted on Shopify. The document body, though partially corrupted, contains text suggesting it is a 'Linux command line cheat sheet pdf', which serves as a lure. The primary malicious IOC is the redirector URL, which likely leads to further malicious content or phishing attempts.
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.
-
Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LUREDocument tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context
-
