By Dan Kobialka – The FBI recently warned U.S. organizations about LockerGaga and MegaCortex ransomware attacks, according to BleepingComputer. It also provided tips to help organizations guard against LockerGaga and MegaCortex.

LockerGaga and MegaCortex control an organization’s network via exploits, phishing attacks, SQL injections and stolen login credentials, FBI noted. They then attempt to encrypt all network devices.

In addition, LockerGaga and MegaCortex use the Cobalt Strike penetration testing tool to deploy “beacons” on a compromised device, FBI stated. This allows the ransomware to perform various activities on a victim’s device.

Cybercriminals typically infect a victim’s device with LockerGaga or MegaCortex but wait several months before they deploy the ransomware, FBI indicated. Once cybercriminals execute a LockerGaga or MegaCortex cyberattack, they stop an infected device’s security program processes and services and disable Windows Defender scanning features and any security-related services.
