A new ransomware threat, Petya, is being reported. Ransomware is a type of malware that encrypts the files on your computer and holds the information hostage in an attempt to extort payment for its release.
Similar to the WannaCry threat, Petya exploits the Microsoft Vulnerability MS17-10: Security Update for Microsoft Windows SMB Server. In addition, once it initially infects a computer, it then installs a tool to acquire usernames and passwords on the infected machine and uses the credentials in an attempt to connect to and infect other computers. For more information about Petya, read the post by Symantec “Petya ransomware outbreak: Here’s what you need to know.”
UITS recommends that you run Windows updates on all Windows computers to ensure your computer is patched. For information on how to check the status of your updates and download, if needed, the latest security patches plus additional tips on how to protect your computer and data from ransonware, view the UITS Ransomware Guide.
