T1204.002 Malicious Link
T1059.003 Windows Command Shell
The PDF contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/pify?keyword=chapter+18+endocrine+system+worksheet'. Additionally, the document body contains text that appears to be a worksheet lure, instructing the user to interact with URLs. The heuristic 'SE_CLIPBOARD_COMMAND_LURE' suggests the document may also attempt to trick users into executing commands. The presence of numerous PDF links, many hosted on Shopify, indicates a link farm strategy to distribute malicious content.
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
-
