Names	OCEANMAP
Category	Malware
Type	Backdoor
Description	(BleepingComputer) Another tool used as part of the attack is the 'OCEANMAP,' a C# backdoor used primarily for executing base64-encoded commands via cmd.exe. OCEANMAP establishes persistence on the system by creating a .URL file named 'VMSearch.url' in the Windows Startup folder. OCEANMAP uses the Internet Message Access Protocol (IMAP) as a control channel to receive commands discreetly that are unlikely to raise alarms, storing them as email drafts containing the command, username, and OS version.
