Hunt Ransomware ([email protected]) – Decrypt Guide & Removal– Gridinsoft Blog | #hacking | #cybersecurity | #infosec | #comptia | #pentest | #ransomware

Hunt ransomware is a new sample of the Dharma/CrySis ransomware family that appeared on April 5, 2024. This malware aims at encrypting the files and asking a ransom payment for their decryption. It unselectively targets both home users and corporations, correcting the ransom depending on the target. Jakub Kroustek was the first to discover this malware.

Ransomware remains a major threat, attacking both organizations and individuals. GridinSoft Anti-Malware provides excellent protection even against the most modern malware samples. 👉🏼 Get yourself proper ransomware protection

As I’ve said in the introduction, Hunt is a novice sample of the Dharma ransomware family. Being its part, Hunt ransomware follows its behavior patterns. The most noticeable one for the victim is the application of a complex extension, that contains the victim’s ID, the contact email (bughunt@keemail[.]me) and its .hunt extension. The files start looking as below after the encryption:

Encrypted files after the Hunt ransomware attack

Hunt ransomware goes through the entirety of user disks, searching for the files it can encrypt. It is capable of ciphering the vast majority of ones, from images and videos to project files of specific software suites. However, this malware carefully avoids any system files – probably, to prevent system malfunctions that can potentially force the user into reinstalling the system.

Before applying the encryption, this malware disables built-in Windows backup options, such as Restore Points and Shadow Copies. They are rather useful for reverting the system state to pre-encryption, so such action is rather expected. Hunt ransomware uses the command you can see below to accomplish this.

vssadmin delete shadows /all /quiet

After finishing the encryption (i.e. it can’t find more unencrypted files), Hunt ransomware spawns a text file with a ransom note. It also opens an HTA file with the information about with more detailed information about what’s happened and instructions for the ransom payment. You can see the example of this pop-up window below.

How to Decrypt .hunt Files?

There is no dedicated decrypting utility for Hunt ransomware available at the moment. This malware uses strong encryption algorithms, so brute force will take gazillion years to accomplish. However, not everything is lost – tools that exploit flaws in encryption algos may appear, or law enforcement may take the ransomware down and release the decryption keys. During the first quarter of 2024, several decryption tools were released, so chances are not that slim.

For now, I can advise you to seek backups outside of the infected system. Cloud storages can contain the files this malware damaged in the attack. Places like social media, email conversations and messengers may contain the originals of the files, too. Even though they may not contain the latest changes, it is better than nothing.

How to Remove Ransomware?

To get rid of the ransomware, I recommend using GridinSoft Anti-Malware. This step is incredibly important to do before performing any attempts to recover the files. The malware remains active, and will instantly encrypt the fresh files. To prevent this and get rid of the infection, run a Full Scan with GridinSoft program and clean all the detected malicious programs.
