MITRE ATT&CK
T1204.002 Malicious File T1559.001 Component Object Model Hijacking

The PDF file contains an embedded object and triggers a critical heuristic for CVE-2010-0188, indicating it exploits a vulnerability in Adobe Reader's LibTIFF component. This exploit is designed to download and execute a secondary payload, as suggested by the 'Pdf.Exploit.Dropped-90' ClamAV detection and the presence of an embedded binary artifact. The attack pattern is consistent with a malicious document designed for initial compromise.

Heuristics 5

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
