File Type: EXE

Memory Resident: Yes

Initial Samples Received Date: 15 Jan 2016

Arrival Details

This worm arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This worm drops the following copies of itself into the affected system:

%Program Files%\meex.exe

(Note: %Program Files% is the Program Files folder, where it usually is C:\Program Files on all Windows operating system versions; C:\Program Files (x86) for 32-bit applications running on Windows 64-bit operating systems.)

It drops the following copies of itself into the affected system and executes them:

%Program Files%\Common Files\System\hmbduoj.exe

It terminates the execution of the copy it initially executed and executes the copy it drops instead.

Autostart Technique

This worm adds the following Image File Execution Options registry entries to automatically execute itself whenever certain applications are run:
