Today, with the rapid development of network technology, more and more enterprises are beginning to realize the importance of enterprise data security. Many enterprises rely on digital office system software and use system software to store important enterprise data in databases, providing services for enterprises. Production operations have provided great convenience, but network threats have always existed. Recently, Yuntian Data Recovery Center has received requests for help from many companies. The company's computer servers have been attacked by the halo ransomware virus, causing the company's important data to be encrypted, seriously affecting It affects the data security of enterprises and brings great difficulties to the production and operation of enterprises. After Yuntian Data Recovery Center decrypted the halo ransomware virus, we specially compiled the following information about the virus for everyone.
- Halo ransomware characteristics
- Performance after poisoning: After the computer server is infected by the halo ransomware virus, the computer is almost paralyzed, all office software cannot operate normally, and the suffix names of all files in the computer server become halo, such as jiemihuifu.mdf files. It will become jiemihuifu.mdf.halo, and a ransom note named !_INFO will be left on the computer desktop.
- Attack encryption upgrade, halo ransomware is a ransomware virus under the Beijingcrypt ransomware family. This virus has a strong form of attack encryption. It uses remote desktop weak passwords and email attachments or bundled software to attack computers. It combines RSA and The upgraded encryption algorithm of AES encrypts computer files. Once the computer server is attacked by the virus, it will be difficult to decrypt it by itself.
- After being poisoned, the halo ransomware virus will bring serious economic losses to the enterprise, and will also cause the leakage of important enterprise data and personal privacy data in the computer, seriously affecting the enterprise's data security and bringing a negative impact on the enterprise's reputation and reputation. damage and affect the normal work and business development of the enterprise.
- Halo ransomware decryption
- Whole machine decryption. The halo ransomware virus has a strong encryption form, which is difficult for non-professional technicians to crack on their own. If the office data file format required by the enterprise to be decrypted contains images or videos, the whole machine needs to be decrypted. The whole machine decrypted data can be restored to integrity. High speed, data recovery is safe and efficient.
- Backup and recovery, generally enterprises have the habit of backing up. Enterprises can use uninfected backup files to restore the system to the state before the backup. This operation is simple and brings less risk and loss. It only requires a full scan and format. System, after cleaning the system viruses, reinstall the system deployment application software and import the backup file to complete.
- Database decryption, after so many years of decryption experience, most enterprise data will be stored in the database. Generally, enterprises recover more data files. We can contact professional data recovery agencies. They have rich experience in data decryption and recovery. Through Analyze and detect to develop a reasonable data recovery and decryption plan.
- Halo ransomware protection
- Reduce port mapping and sharing operations to avoid computer port leaks.
- Install reliable protection software, regularly scan and kill computer systems, and patch vulnerabilities.
- Regularly maintain the password of the computer server. The passwords of different computer servers should be different and as complex as possible.
- Back up system files regularly to prevent special situations from occurring.
- Improve the network security awareness of all employees.
