INFO: WannaCrypt Ransomware Attacks

imageToday, many of our customers around the world and the critical systems they depend on were victims of malicious “WannaCrypt” software. Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful. Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers.

We are using the MSRC blog – Customer Guidance for WannaCrypt attacks to post information and resources in one place, to help customers respond to this latest threat.

The first and most important piece of guidance is to immediately deploy the security update associated with Microsoft Security Bulletin MS17-010, if you have not done so already. Customers that have automatic updates enabled or have deployed this update are already protected from the vulnerability these attacks are trying to exploit.
