MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file was flagged by ClamAV with 'Heuristics.PDF.ObfuscatedNameObject', indicating a suspicious structure. Furthermore, a PDF_EMBEDDED heuristic indicates the presence of an embedded file, 'embedded_file_obj0001.bin', which is a common technique for delivering malicious payloads. The document body content is heavily obfuscated and unreadable, providing no further clues about the specific lure.
