Malware Insights
The PDF file contains a deceptive document body referencing 'Chamsys show file' to trick users into clicking embedded links. Analysis reveals a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating that one of the embedded URLs, specifically 'https://ttraff.com/pify?keyword=chamsys+show+file', leads to known malicious redirector infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic indicates a large number of embedded links, with 'https://cdn.shopify.com/s/files/1/0432/8144/9126/files/xolotatokekunerenufum.pdf' being the first identified in this farm. The file's purpose is to drive traffic to malicious sites through social engineering.
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.
