  OVERVIEW


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.

It drops an AUTORUN.INF file to automatically execute the copies it drops when a user accesses the drives of an affected system.

It deletes itself after execution.

  TECHNICAL DETAILS

File Size:

36,219 bytes

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

(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 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:

Propagation

This worm drops copies of itself in the following shared folders:

  • %Program Files%\Common Files\Microsoft Shared\tygxhqb.exe <- executed afterwards

(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 copy(ies) of itself in all removable drives:

  • {Removable Drive Letter}:\pfcexkt.exe

It drops an AUTORUN.INF file to automatically execute the copies it drops when a user accesses the drives of an affected system.

Dropping Routine

This worm drops the following files:

  • %Program Files%\1.hiv
  • %Program Files%\2.hiv
  • %Program Files%\3.hiv
  • %Program Files%\4.hiv
  • %Program Files%\Common Files\Microsoft Shared\gvdetru.inf
  • %Program Files%\Common Files\System\gvdetru.inf

(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.)

Other Details

This worm connects to the following possibly malicious URL:

  • http://xx.{BLOCKED}e.cn/yj/1009.exe
  • http://xx.{BLOCKED}e.cn/yj/yj.txt

It deletes itself after execution.
