What is Egrego Ransomware?

Egrego ransomware is a type of malware that encrypts all the files in a computer until the user pays a ransom. The files encrypted by Egrego will have a Random extension (e.g., ".JhWeA") extension appended at the end of the file name. Egrego is delivered through a Win32 DLL file and has been spotted inside the following files and processes: ['260828.dll', 'b.dll']

What is ransomware?

Ransomware is a type of malware that encrypts a user’s files, making them inaccessible, and demands a ransom payment to restore access. The most common type of ransomware is known as “crypto-ransomware,” which encrypts files and demands a ransom payment to decrypt files.

How Does ransomware Spread?

Ransomware can come from a variety of sources. These include but are not limited to phishing emails, malicious links, social engineering tricks, and other social engineering attacks. Once ransomware is installed on a device, it can spread to other devices on the same network. This is done by either sharing the ransomware with other devices on the same network or by spreading it to other devices on the internet. Once ransomware is in place and running, it can start encrypting files on the machine, blocking the legitimate user from accessing their own data.

Egrego ransomware Capabilities:

Egrego ransomware may use process injection techniques to evade process-based defenses as well as to elevate privileges. By injecting code into other processes, Egrego may access those processes' memory, system/network resources, and possibly elevated privileges. This may also help to evade detection from security products. Additionally, Egrego ransomware may use redirected/tunneled protocols such as Serial over LAN to communicate with infected hosts. Egrego ransomware may use System Information Discovery techniques to gather detailed information about the target system, including operating system version, patches, and architecture.

Mitigations Against Egrego ransomware:

Egrego ransomware can be mitigated by some endpoint security solutions that can be configured to block process injection. Endpoint security solutions that include behavior-based detection can detect and block Egrego ransomware.Egrego ransomware can also be blocked through the use of application whitelisting. Regular backups can help protect against data loss in the event of an Egrego ransomware attack. You can also filter network traffic to prevent the use of unnecessary protocols.
