Threat Update – WannaCry Ransomware
| As of this writing, the WannaCry ransomware outbreak infected 350,000 victims in more than 150 countries. As a customer, we want to keep you up-to-date on the latest information about the threat and our response. |
| What makes WannaCry unique? WannaCry is a unique ransomware strain that exploits a critical Microsoft Windows Server Message Block (SMB) vulnerability to spread like a worm, lending to its rapid propagation after just a few hours of initial detection. The SMB exploit spreads across network shares, so the effect of the attack was minimal to consumers.The unique trifecta of a broadly available vulnerability with a working exploit and the ability for execution without human intervention created the perfect environment for a “wormable” ransomware attack. Since the WannaCry attack, another attack called Adylkuzz has surfaced that takes advantage of the same Windows vulnerability, emphasizing the need for action. |
| What was McAfee’s response? Over the course of Friday, May 12, McAfee received multiple reports of the attack. By Friday afternoon, the McAfee® Global Threat Intelligence system was updated to identify all known WannaCry samples, and McAfee had delivered DAT signature updates to all its customers.Our enterprise endpoint products provide zero-day protection against the attack as outlined below. As new variants of this ransomware arise, we will continuously update our software to keep our users protected. |
