Malware Insights
The PDF file was flagged by multiple critical heuristics for containing malicious redirector links and a large link farm. The embedded URLs, particularly the one pointing to 'ttraff.ru', are indicative of a phishing or malware distribution attempt. The document body, though partially corrupted, contains text related to a 'Tarte concealer shade guide' and the authoring application, suggesting a lure to disguise the malicious intent. The presence of numerous external links, many hosted on Shopify but others on suspicious domains, reinforces the attack pattern of redirecting users to potentially harmful content.
Machine Learning
- Nyx PDF Classifier malicious score 1.0000
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.
