MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a 'Pdf.Phishing.Trojan' signature. It contains multiple embedded URLs, one of which, 'https://pelibifir.ru/award?keyword=borg+rate+of+perceived+exertion+scale+pdf', is flagged as an external URI. The document body is heavily obfuscated, but the presence of these URLs suggests an attempt to redirect the user to malicious content, likely for phishing or to download further payloads. No scripts were extracted from this sample.
