Assuming this isn't a web or outward facing server, you shouldn't need to worry about it catching a virus as it's only you and other IT staff accessing it directly (if even at all).

The best free AV for a server is none at all. enable passwordless authentication methods.Jun 25th, 2019 at 5:05 PM.enforce MFA on various accounts and strictly require MFA from all devices.prioritize the deployment of Active Directory updates.Avoiding these newer Hive ransomware variants can be possible with the use of included IOCs to investigate whether they exist in the particular environment and assess for potential intrusion. There are things that researchers recommend customers to do. However, malware like this needs to evolve since there are various mitigation methods that allow researchers to keep networks secure and not vulnerable to ransomware. These people are financially motivated, so ransom demands grow out of control with double and triple extortion methods that many of them adopt. There are other groups affecting organizations and users across the world. This ransomware-as-a-service is only one of the most dangerous ones. key extension What can be done to mitigate attacks? Instead of embedding an encrypted key in each file that it encrypts, it generates two sets of keys in memory, uses them to encrypt files, and then encrypts and writes the sets to the root of the drive it encrypts, both with. Ransomware gets some additional features that help stop services and processes related to security solutions that stop these attacks.Ĭhanges to the variants that are Rust-based now mean that ransomware not only deletes backups to prevent easy file recovery, but the threat also goes for the file encryption differently: Ransomware now can be resistant to reverse engineering, so the threat is more evasive and cannot be easily detected by threat fighting tools or researchers, so campaigns are more widespread and can be more successful. New malware versions now use a wide range of cryptographic libraries. Malware gains additional benefits from this because memory safety gets improved and deeper control over low-level resources helps to evolve the infection. The change from GoLang to Rust makes this ransomware second threat family after the BlackCat that is written in this programming language. Shift to a different and not common programming language Actors manage to achieve their goals in less than a few days to encrypt company environments. Various samples show that attacks carried out by the affiliate involve the exploitation of ProxyShell flaws in the Microsoft Exchange Server too. These Hive ransomware attacks are focused on organizations, so these infection campaigns need to be targeted. It is compared to major strains like Black Basta and Conti. The threat had at least 17 victims in the month of May this year. This virus was first observed in June 2021 and has emerged as one of the most dangerous RaaS groups since then. It is the continuously changing ransomware ecosystem, as the threat research team from Microsoft reports. Hive ransomware is one of the fastest evolving threat families, and these additions prove that.

The ransomware-as-a-service upgrades the full code migration to another programming language, so the infection uses a more complex encryption method.

Developers of the virus overhauled their file-encrypting software and migrated fully to Rust. One of the most prevalent ransomware viruses out there received upgrades to the latest variants that change the encryption and other features. New upgrades make the ransomware persistent to reverse engineering and using more advanced encryption After a year since the discovery Hive ransomware virus latest versions carry major upgrades
