The FBI urges transparency to law enforcement agencies when ransomware incidents occur. When it comes to Conti specifically, the FBI has requested boundary network device logs and security event logs showing links to IP addresses, cryptocurrency wallet information, any decryptor files available, as well as encrypted file samples. To protect against ransomware attacks, organizations should regularly back up data, air gap or properly segment Operational Technology (OT) networks from Internet-connected networks, and password protect backup copies offline. Ensure copies of critical data are not accessible for modification or deletion from the system where the data resides. Implement network segmentation. Implement a recovery plan to maintain and retain multiple copies of sensitive or proprietary data and servers in a physically separate, segmented, secure location (i.e., hard drive, storage device, the cloud). Install updates/patch operating systems, software, and firmware as soon as they are released. Use multi-factor authentication where possible. Use strong passwords and regularly change passwords to network systems and accounts, implementing the shortest acceptable timeframe for password changes. Avoid reusing passwords for multiple accounts. Focus on cyber security awareness and training. Regularly provide users with training on information security principles and techniques as well as overall emerging cybersecurity risks and vulnerabilities.
