WannaCry Ransomware spreading stopped – Thanks to Microsoft and MalwareTech security firm

As a reminder, WannaCry Ransomware is a ransomware malware created to use some exploits harvested from NSA hack. The infection spread in over 70 countries.

Microsoft has patched this issue, so the users that run supported Windows versions, Windows 7, Windows 8.1 and Windows 10, are safe if they have all the system updates installed and Windows Defender enables.

But despite this, Microsoft has published an emergency update for all the Windows systems (except Vista), in order to block the WannaCry ransomware, flagged by Microsoft Ransom:Win32/WannaCrypt .

Download the update patch matching your operating system and architecture:

All you have to do in order to patch your system is to download the update and install.

On top of Microsoft’s work to update and secure operating systems which reached EOL (end of life), a cybersecurity researcher from MalwareTech handle has managed to stop the WannaCry infection from spreading.

The researcher has studied the code and found a kill switch, hardcoded by the creator of the code in case he wanted to stop it from spreading. The malware was designed to stop if it got response from an internet domain, so the MalwareTech company registered that domain since the attacker did not bother to buy that domain.

According to Bitdefender, the malware spread in 104 countries, infected 180.000 devices, and only 102 victims decided to pay the $300 Bitcoin ransom.

As a piece of advice, as I said in the previous article, you should download the right patch for your operating system, keep Windows Defender active and do not open malicious mails.
