US-CERT has received multiple reports of WannaCry ransomware infections in several countries around the 
world.Ransomware [ https://www.us-cert.gov/security-publications/Ransomware ] is a type of malicious software that 
infects a computer and restricts users access to it until a ransom is paid to unlock it. Individuals and organizations 
are discouraged from paying the ransom, as this does not guarantee access will be restored.

Ransomware spreads easily when it encounters unpatched or outdated software. The WannaCry ransomware may be exploiting 
a vulnerability in Server Message Block 1.0 (SMBv1). For information on how to mitigate this vulnerability, review the 
US-CERT article onMicrosoft SMBv1 Vulnerability [ 
https://www.us-cert.gov/ncas/current-activity/2017/03/16/Microsoft-SMBv1-Vulnerability ] and the Microsoft Security 
Bulletin MS17-010 [ https://technet.microsoft.com/library/security/MS17-010 ]. Users and administrators are encouraged 
to review the US-CERT Alert TA16-091A [ https://www.us-cert.gov/ncas/alerts/TA16-091A ] to learn how to best protect 
against ransomware. Please report any ransomware incidents to the Internet Crime Complaint Center (IC3) [ 
https://www.ic3.gov/default.aspx ].
