MITRE ATT&CK
T1204.002 Malicious File T1566.002 Spearphishing Attachment T1190 Exploit Public-Facing Application

The sample is a PDF document that contains an embedded file and triggers the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader related to XFA forms and TIFF image parsing. The embedded file, likely the malicious payload, was detected by ClamAV as Pdf.Exploit.Dropped-90. The attack pattern involves luring the user to open a malicious PDF which then exploits a known vulnerability to compromise the system.
