WanaCry Ransomware

WanaCrypt, or also known as WanaCry, is a new ransomware that wreaked havoc across the world last night, which spreads like a worm by leveraging a Windows SMB vulnerability (MS17-010) that has been previously fixed by Microsoft in March. In these attacks, data is encrypted with the extension “.WCRY” added to the filenames. “WannaCry”, is initiated through an SMBv2 remote code execution in Microsoft Windows. This exploit (codenamed “EternalBlue”) has been made available on the internet through the Shadowbrokers dump on April 14th, 2017 and patched by Microsoft on March 14.

Unfortunately, it appears that many organizations have not yet installed the patch.

In the wake of the largest ransomware attack in the history that had already infected over 114,000 Windows systems worldwide since last 24 hours, Microsoft just took an unusual step to protect its customers with out-of-date computers. Microsoft has just released an emergency security patch update for all its unsupported version of Windows, including Windows XP, Vista, Windows 8, Server 2003 and 2008 Editions.
