Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/strik?utm_term=concrete+calculator+lowes'. Additionally, it features a PDF link farm heuristic, indicating a large number of external links, one of which is 'https://s3.amazonaws.com/xojafemori/quality_management_system_template_free.pdf'. The ML classifier also flagged the PDF with a high score, and ClamAV detected it as 'Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0'. The document body is heavily obfuscated, but the presence of these indicators strongly suggests a phishing or malware distribution attempt.
