MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
T1059.001 PowerShell
The PDF file contains a lure suggesting it is a service manual, but it embeds a link to a known malicious redirector. The document body, though heavily obfuscated, contains the malicious URL and appears to be generated by wkhtmltopdf, a tool often used to create SEO spam PDFs. The primary malicious activity observed is the redirection to a malicious URL, likely intended to deliver a second-stage payload or phish for credentials.
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.
-
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.ru/wix?keyword=whitfield+pellet+stove+service+manua
