Foreword: In recent years, the outbreak of ransomware viruses has caused many users to suffer a lot. Especially some small and medium-sized enterprises, which have almost no network security protection, are easily infected by viruses, causing not only financial losses, but also The important thing is that in terms of business and customer trust, it has caused invisible damage and caused irreversible harm to the enterprise. The suffix babyk ransomware virus is a very active virus recently. Recently, it has received many messages from users asking for help, saying that all files are encrypted and cannot be accessed. This article will explain what to do if the server is infected with the babyk ransomware virus.
Characteristics and propagation method: The babyk ransomware virus is a typical encrypted ransomware virus. This is the most common type of ransomware virus. It encrypts the user's files and locks them. Encrypted ransomware can also selectively encrypt files based on file types, such as only encrypting specific types of files such as documents, pictures, and videos. But it also has the characteristics of a network-based ransomware virus, which can exploit software vulnerabilities or weak passwords to invade computers and then encrypt files or lock the screen. Its propagation methods are also diverse, usually in the form of spam, server intrusion, web page Trojans, bundled software, etc. Once a machine is attacked by a ransomware virus, most of the files will be modified by the encryption algorithm and a special suffix will be added, and the user will be unable to read the original normal files, causing immeasurable losses to the user.
Prevention methods:
1. Efficient data backup: Organizations must adopt a regular data backup and recovery plan for all critical data they store. Backups should be tested and backup data must be stored on a separate device, preferably offline.
2. Regular patch updates: Application patches and operating system patches must be up-to-date and tested to avoid any potential vulnerabilities. Efficient patch management reduces the likelihood of attacks through exploitable weak links.
3. Limit the use of elevated privileges: Organizations should follow a restricted permissions model for user access to reduce the chance of them installing and running unwanted software or applications.
4. Antivirus updates: The system must have the latest antivirus software installed and all downloaded files must be scanned through it.
5. Implement application whitelisting: Organizations must follow an application whitelisting process to prevent systems and networks from being infected by malicious or unauthorized applications.
6. Create user awareness: Users are the weakest link in cybersecurity and it is important to educate them through proper training. Security professionals must be aware of the latest trends in this area and need to educate users about spam and phishing attacks.
7. Email Protection: Organizations must keep a close eye on their emails. They should block emails with attachments from suspicious sources.
8. Endpoint protection: Organizations must protect endpoints by preventing malicious files from running.
9. Develop good security practices: Organizations must maintain good security habits and security practices while browsing the web and must protect data with appropriate controls
Recovery plan:
Currently there are two types:
Decrypt the whole machine: Buy the key from a hacker, please choose carefully, there are risks
Recovery of important files such as databases (data966): Since there are loopholes in the encryption of large files by hackers, we can restore the data completely through technical means. If you only need your important data, try this solution.
