The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.ru'. The document body, though heavily corrupted, contains text fragments related to 'Avd manager not available in android studio' and the URL itself, suggesting a social engineering lure. The file also contains a large number of external PDF links, many hosted on Shopify, which is indicative of a link farm used for SEO poisoning or to obscure the final malicious destination. The primary IOC is the redirector URL.
Heuristics 3
-
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.
-
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=avd+manager+not+available+in+android+studio
