FBI urges victims to report the incident to the local FBI field office and to ic3
“Regardless of whether you or your organization have decided to pay the ransom, the FBI urges you to report ransomware incidents to law enforcement.” continues the announcement. “Doing so provides investigators with the critical information they need to track ransomware attackers, hold them accountable under U.S.
Reporting the ransomware attacks to the FBI will help law enforcement to track the crooks behind the campaign and to collect the indicators of compromise associated with the threat.
Below the cyber defense best practices shared by the FBI:
• Regularly back up data and verify its integrity
• Focus on awareness and training
• Patch the operating system, software, and firmware on devices
• Enable anti-malware auto-update and perform regular scans
• Implement the least privilege for file, directory, and network share permissions
• Disable macro scripts from Office files transmitted via email
• Implement software restriction policies and controls
• Employ best practices for use of RDP
• Implement application whitelisting
• Implement physical and logical separation of networks and data for different org units
