MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
T1059.003 Command and Scripting Interpreter: Windows Command Shell
The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/pify?keyword=internet++manager+firefox+56'. The document body and heuristics indicate a social engineering lure, instructing the user to install a browser update or extension, which is a common method for malware delivery. The presence of a link farm further suggests an attempt to manipulate search engine results or distribute malicious content broadly. The file's purpose appears to be directing users to malicious infrastructure via a deceptive link.
Heuristics 5
-
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
-
Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
-
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.cc/pify?keyword=internet++manager+firefox+56
