File MD5: 0x9981E9BC98A69A949D1D6F22A3770BB2
File SHA-1: 0x8AA720533EC74537EEDA80E72552E210FB4A69DD
Filesize: 626,688 bytes
Alias: Trojan.Win32.Pakes [Ikarus]

Summary of the findings:

What's been found	Severity Level
Is protected with Themida in order to prevent the sample from being reverse-engineered. Themida protection can potentially be used by a threat to complicate the manual threat analysis (e.g. the sample would not run under the Virtual Machine).
Registers a 32-bit in-process server DLL.
