Thus, it is important and would be interesting to know how they enter into our system.

The secret way: How WinLock Virus enters the computer?

Most of the computer viruses including WinLock enters into your computer from these ways.

  1. A very common way of entry is CD/DVD or U.S.B. Drives.
  2. Viruses spread through LAN (Local Area Network). If an infected system is connected to a healthy network, then the whole network gets infected.
  3. If you download software from free websites, then you might sacrifice your privacy and system to virus infections.
  4. Infected email attachments
  5. Fake updates that trick you installing them
  6. Infected documents circulating on peer-to-peer (P2P) file-sharing networks, torrent sites, and IRC channels.

WinLock prevents users from accessing files on their computer and demand the payment fee in order to regain access. The virus infection display messages on the victim's desktop which a user can’t bypass as their computer is effectively locked up through a complex encryption mechanism.

The virus even claims that the user broke the law by viewing some illegal content. In addition to this fake message, there is a set deadline with instructions on how to pay the virus for getting complete access to your computer.

Moreover, the infection is capable of hitting all private and corporate computers whereas the amount of payment fee required depends on the type of user and its geographic location.

“WinLock reports show that the hackers rarely live up to their promise even after getting paid. In most cases, victims are left without data on trusting the criminals instead of removing WinLock virus.”

Therefore, victims of a WinLock infection should remove the virus by using Malware Crusher, rather than paying the virus developers.

How does a WinLock virus work?

Upon successful infiltration, the virus creates its files and modify system files and registry entries. WinLock is the first cyber infection which uses  C&C panels.

Some panels verify the payment to the hackers and authorize the unlocking of the infected machines; a few other manages the administrative operations such as sending the unlock commands.

Even more, hackers now use such Control Panel platform, created a crimeware service and a WinLock Affiliate Program to sell the service to cyber hackers and attackers.

The WinLock virus uses a complicated 3-layered rootkit ring which executes the malicious operations. This rootkit further uses API hooking that modifies the process and behavior of the Windows operating system.

As the result, WinLock virus bypasses the User Account Control and the Data Execution Prevention services to lock the entire operating system.

WinLock installs as an ''.exe'' file with a fake name in the ''C:\PROGRAMFILES\system'' folder. The ''.exe'' file relates to a ''key.txt'' file containing system configuration information used to restore the system.

WinLock virus also uses Windows Active Template Library to communicate with the victim on the one side and sends data back to the hacker’s C&C panel on the other.

The user-specific information request sent by WinLock is like this;

WinLock modifies and deletes the Windows registry, few related to safe mode and system restore are given below;

HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal

HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network

Furthermore, WinLock disable the registry keys by adding “DiableConfig” and “DisableSR” in;

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\SystemRestore HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\SystemRestore

This prevents the user from using the system recovery option and infects the Windows operating system.
