MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was detected by ClamAV as Pdf.Exploit.Agent-19993, indicating it contains known exploit code. A hidden HTML iframe was also found, which is a common technique for redirecting users to malicious sites. The embedded URLs point to suspicious domains, likely serving as landing pages for further exploitation or malware delivery. No scripts were extracted from this sample, but the combination of exploit detection and embedded URLs strongly suggests a malicious intent to compromise the user's system.

  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
