The PDF file contains a large number of embedded links, many of which point to external websites, indicating a link farm. One critical heuristic firing confirms that the PDF links to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains URLs that are likely part of this redirection scheme. The presence of 'SE_LOLBIN_RUN_COMMAND' suggests that the PDF may also contain instructions or embedded scripts that attempt to execute commands on the user's system, potentially to download further payloads or establish persistence.
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.ru/pify?keyword=jeux+pour+apprendre+l+anglais+en+s+amusant+pdf
