What is LockerGoga ransomware? And how does it execute its attack?

LockerGoga ransomware is a data-encrypting malware that was found to target several companies in Europe. Its first attack was on the system of Altran Technologies which made the company shut down its IT network and all applications to protect the data of its clients, employees, and partners and since then, it targeted other companies. It uses a “.locked” extension in marking the files it encrypts.

LockerGoga Ransomware

Once it executes its attack on a targeted machine, LockerGoga ransomware will drop its payload file and connect the computer to a remote Command and Control server controlled by the attackers. From this remote server, LockerGoga ransomware will download several malicious components and place them on system folders. They will be used to employ a data gathering module which is the one that collects information from the computer as well as the users. Afterward, it uses the data collected to employ the next module called stealth protection which is the one that scans the system for strings of antivirus programs, a sandbox environment, and security programs that might interfere with the attack. After it finds these programs, it either removes them or disables them.

LockerGoga ransomware also modifies some existing entries in the Windows Registry as well as creates new ones. This allows the crypto-virus to run automatically on every system startup, making its attack a persistent one. After these modifications, it starts encrypting its targeted files using a combination of AES 256 and RSA 4096 encryption algorithms. Following the encryption, it adds the .locked suffix to every affected file and drops a text file named “README-NOW.txt” which contains the following message:

There was a significant flaw in the security system of your company.
