Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.ru', which is used in a lure to trick users into executing commands. The document body explicitly instructs the user to copy and paste content into a shell context, aligning with the 'SE_CLIPBOARD_COMMAND_LURE' heuristic. This suggests the PDF is designed to facilitate the execution of further malicious code, likely by downloading a payload from the provided URL. The presence of numerous external PDF links also indicates a link farm strategy, potentially for SEO poisoning or distributing 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
-
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.ru/pify?keyword=how+to+upload+projects+to+github
