Original release date: May 12, 2017
US-CERT has received multiple reports of ransomware infections in several countries around the world. 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.
Users and administrators are encouraged to review the US-CERT Alert TA16-091A to learn how to best protect against ransomware. Please report any ransomware incidents to the Internet Crime Complaint Center (IC3).
