Malware researchers at Trend Micro have analyzed a malware that connects to the home routers and scan the home network then send the gathered information to C&C before deleting it self .

TROJ_VICEPASS.A pretends to be an Adobe Flash update, once its run it will attempt to connect to the home router admin council using a predefined list of user names and passwords. If it’s succeed, the malware will scan the network for connected devices.

The malware scans for devices using HTTP, with a target IP range of 192.168.[0-6].0-192.168.[0-6].11, this IP range is hard-coded

Once the scans is finish it will encode the result using Base64 and encrypt it using a self-made encryption method. The encrypted result will be sent to a C&C server via HTTP protocol.

After sending the results to the Command and Control server (C&C) , it will delete itself from the victim’s computer. It uses the following command to do so:

  • exe /C ping -n 1 -w 3000 > Nul & Del “%s”

Such type of malware infection can be avoided using a very basic security techniques such as downloading updated and software from a trusted sources only and changing the default password of your equipment’s.

Microsoft has announced a new release of the Enhanced Mitigation Experience Toolkit (EMET) 5.2.

The main the main changes and improvements as the following:

  • Control Flow Guard: EMET’s native DLLs have been compiled with Control Flow Guard (CFG). CFG is a new feature introduced in Visual Studio 2015 (and supported by Windows 8.1 and Windows 10) that helps detect and stop attempts of code hijacking. EMET native DLLs (i.e. EMET.DLL) are injected into the application process EMET protects. Since we strongly encourage 3rd party developers to recompile their application to take advantage of this very latest security technology, we have compiled EMET with CFG.
  • Enhanced Protected Mode/Modern IE: EMET now fully supports alerting and reporting from Modern Internet Explorer, or Desktop IE with Enhanced Protected Mode mode enabled.
  • VBScript in Attack Surface Reduction: the configuration for the Attack Surface Reduction (ASR) mitigation has been improved to stop attempts to run the VBScript extension when loaded in the Internet Explorer's Internet Zone. This would mitigate the exploitation technique known as “VBScript God Mode” observed in recent attacks
