Recently, many companies' Kingdee Cloud Xingkong financial account sets were attacked by the locked ransomware virus. Many important data in the financial system were encrypted and could not be opened normally. The emergence of this situation has nothing to do with the enterprise’s network security operation and maintenance and the software itself, because the locked ransomware uses a new form of encryption, uses the network to scan all computers through unique technologies, and after scanning, even inconspicuous vulnerabilities can be used to carry out remote attacks, so as to implant locked ransomware into computers to run encryption programs. This situation is a huge threat to enterprises.
1. Immediate isolation of the source of infection
After discovering that the server database has been attacked by a ransomware virus, the first step is to immediately isolate the source of the infection. Further spread and spread of the virus can be prevented by disconnecting from the network, shutting down the affected server, and notifying those involved to stop using the infected system.
2. Create a data recovery plan
Having a data recovery plan in place is essential when dealing with the event of a ransomware attack. This plan should include strategies for backing up data and restoring data, as well as specific process steps for restoring servers and systems. Backing up data regularly in later work is an important means to prevent data loss.
3. Not negotiating with the attacker
When faced with a ransomware attack, there is absolutely no way to negotiate or pay the ransom. This behavior only encourages attackers to continue similar attacks and does not guarantee that we can actually recover locked data. Instead, we should choose a professional data recovery team to find ways to unlock and recover data. 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 suffix ransomware viruses on the market. The data recovery is highly complete and the data recovery is safe and efficient.
4. Enhanced cyber security measures
The occurrence of ransomware attacks reminds us that it is very necessary to strengthen network security measures. Enterprises should regularly update and upgrade server and system security patches, install and use credible antivirus software and firewalls, and encrypt important data, etc. In addition, employees also need to receive cyber security training to improve their security awareness and skills.
5. Review Security Policies and Processes
The occurrence of ransomware attacks is a wake-up call for businesses to review and improve their security policies and processes. This includes regularly evaluating and updating security policies, strengthening access controls, restricting privileges and access to sensitive information, establishing flexible security backup plans, etc. By continuously improving security policies and processes, an organization's resilience and response capabilities can be enhanced.
When the server database is attacked by ransomware, it is very important to handle and respond correctly. Immediately isolating the source of infection, having a data recovery plan in place without consulting with the attackers, strengthening cybersecurity measures, and reviewing security policies and procedures are critical steps in dealing with this situation. By taking these measures, businesses can minimize losses and effectively resume normal operations of the business. At the same time, it also reminds us to strengthen network security awareness and measures to prevent similar attacks from happening.
