The file was detected by ClamAV as Pdf.Phishing.Trojan. The PDF contains an embedded URI pointing to 'irlanc.ru', which is likely used to redirect the user to a malicious site. The presence of multiple external URLs further supports the phishing or malware distribution intent. No scripts were extracted, but the PDF structure and embedded URI are strong indicators of malicious activity.
