Multiple Ransomware Infections Reported

Original release date: October 24, 2017

US-CERT has received multiple reports of ransomware infections, known as Bad Rabbit, in many countries around the world. A suspected variant of Petya, Bad Rabbit is ransomware—malicious software that infects a computer and restricts user access to the infected machine until a ransom is paid to unlock it. US-CERT discourages individuals and organizations from paying the ransom, as this does not guarantee that access will be restored. Using unpatched and unsupported software may increase the risk of proliferation of cybersecurity threats, such as ransomware.

US-CERT encourages users and administrators to review US-CERT Alerts TA17-181A and TA17-132A that describe recent ransomware events. Please report ransomware incidents to the Internet Crime Complaint Center (IC3). US-CERT will provide updated information as it becomes available.
