Malware Insights
The PDF contains a heuristic firing for a malicious redirector link pointing to 'ttraff.ru', which is associated with malicious activity. Additionally, it includes a large number of embedded links to PDFs hosted on Shopify, suggesting a link farm for SEO poisoning or distribution. The 'SE_CLIPBOARD_COMMAND_LURE' heuristic indicates the document instructs the user to copy and paste content into a command-line interface, a common tactic for executing downloaded payloads. The document body itself is heavily obfuscated and appears to be junk data, but the presence of the URL and the command lure heuristics strongly suggest a malicious intent to trick the user into executing commands.
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=adobe+premiere+cc+tutorial+pdf
