DHS Statement on Ongoing Ransomware Attacks

"The Department of Homeland Security is aware of reports of ransomware known as WannaCry affecting multiple global entities.  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.  Microsoft released a patch in March that addresses this specific vulnerability, and installing this patch will help secure your systems from the threat. Individual users are often the first line of defense against this and other threats, and we encourage all Americans to update your operating systems and implement vigorous cybersecurity practices at home, work, and school.  These practices include:

• Update your systems to include the latest patches and software updates.
• Do not click on or download unfamiliar links or files in emails.
• Back up your data to prevent possible loss, whether you are at a home, work, or school computer..."
