How EmoCheck detects Emotet

Emotet generates their process name from a specific word dictionary and C drive serial number. EmoCheck scans the running process on the host, and find Emotet process from their process name.

(added in v0.0.2)
Emotet keeps their encoded process name in a specific registry key. EmoCheck looks up and decode the registry value, and find it from the process list.

Sample Report

Text stlye:

[Emotet Process]

     Process ID    : 716
     Image Path    : C:\Users\[username]\AppData\Local\mstask.exe

Please remove or isolate the suspicious execution file.
