T1059.001 PowerShell
T1204.002 Malicious Link
The PDF document contains a lure related to 'Atmega328p programming pdf' and embeds multiple links. One of these links, 'https://ttraff.ru/wix?keyword=atmega328p+programming+pdf', is identified as a malicious redirector. The document also instructs the user to install a browser extension or update, which is a common social-engineering tactic for credential theft or malware installation. No scripts were extracted, but the combination of social engineering and malicious links points to a phishing or malware delivery attempt.
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.
-
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
