Guidance for WannaCrypt Attack

Many organizations across the globe were victims of a malicious software attack on Friday. “WannaCrypt” is a type of known attack which locks and prevents access to critical systems and information. Both Microsoft and KiZAN have been monitoring the developments closely, and we want to share the information and the resources that are available.

  • Firstly, Microsoft worked aggressively to ensure the attack was understood and took all possible protective actions. Additionally, Microsoft is using the MSRC blog - Customer Guidance for WannaCrypt attacks- to post information and resources in a single location. This up to date information will help our clients respond appropriately to this latest threat.

  • Secondly, if you have not already done so, it is critical that you immediately deploy the security update associated with Microsoft Security Bulletin MS17-010. Customers that have automatic updates enabled or that have deployed this update already are protected from the vulnerability these attacks are trying to exploit.
