As network security issues become increasingly prominent, enterprise server databases have become one of the important targets of hacker attacks. Recently, we have received requests from many companies for help. The server database of the company has been attacked by a ransomware virus with a 360 suffix. As a result, many important data in the company have been encrypted and cannot be read and used, seriously affecting the normal operation of the company.
The 360 suffix ransomware virus is a virus in the BeijingCrypt ransomware family. It adopts a newly upgraded encryption method, which can quickly identify and encrypt enterprise databases and important files. Once the enterprise is attacked by the 360 suffix ransomware virus, we don’t need to panic. At present, many network security companies have mastered the decryption method of the virus, which can restore the database data for us better and faster. Yuntian Data Recovery Center has a professional data recovery research and development team for many years. It has rich experience in decryption and recovery for various suffixes such as 360 ransomware. The data recovery is highly complete, safe and efficient. Let me share with you some of the ways 360 ransomware attacks encrypted companies, and how to take good network security measures in the later stage.
1. Weak password attack: Many enterprise server databases have weak password problems when setting account passwords, such as using simple passwords and failing to change the default password in time. Hackers can easily find these weak passwords by brute force cracking or using common password dictionaries and log in to the database for attack and encryption.
2. Phishing email attack: Hackers may send emails disguised as legitimate sources to employees or administrators, and contain malicious links or attachments in the emails. If an employee clicks on the link or opens the attachment, malicious programs are silently downloaded to the server and executed, causing the database to be encrypted.
3. Operating system vulnerability attack: The operating system of the enterprise server has vulnerabilities or security patches that have not been patched in time may also become the entry point for hacker attacks. Hackers can exploit these vulnerabilities, enter the server system, and then implement extortion by encrypting the database.
4. Remote desktop (RDP) attack: The remote desktop service is enabled on the enterprise server and a weak password is set. Hackers can use brute force cracking tools or exposed RDP vulnerabilities to obtain administrator privileges and further encrypt the database.
5. Malware intrusion: Hackers may inject malware into enterprise servers through various means, such as implanting Trojan horses and exploiting vulnerabilities. Once the malware executes successfully, it usually searches the database and encrypts the files within it.
6. Social engineering attack: Hackers use social engineering methods to trick system administrators into revealing authentication information or performing malicious operations by disguising themselves as employees, suppliers, or other partners. This allows hackers to log into the server with administrator privileges and encrypt the database.
In order to prevent 360 suffix ransomware from attacking encrypted databases, enterprises can take the following security measures:
1. Keep updated: timely install security patches for the operating system and database software, fix known vulnerabilities, and prevent hackers from exploiting them.
2. Strong Password Policy: Require employees to use strong passwords and change them regularly. Avoid using simple or default passwords.
3. Restrict remote access: Only enable remote desktop services when necessary, and limit access IP ranges and login attempts.
4. Firewall and intrusion detection system: configure and update the firewall, only allow authorized IP addresses to access the server, add an intrusion detection system, and implement real-time monitoring and alarm mechanisms.
5. Employee education and training: Strengthen employees' awareness of network security and educate them on how to identify and respond to common attack methods such as phishing emails and malicious links.
6. Data backup and recovery: Regularly back up the enterprise server database and store it offline and in a safe place. In this way, even if attacked, the data can be recovered quickly without paying ransom fees.
In short, the 360 suffix ransomware attack is a very dangerous network virus with high destructive power and various attack methods. Enterprises should attach importance to database security and take comprehensive security measures to protect enterprise server databases to reduce the risk of being encrypted.
