How to remove Hudson Ransomware and decrypt .{victim’s_ID}.hudson files

What is Hudson Ransomware

Discovered by our team of researchers, Hudson Ransomware is a malicious software that encrypts files on infected systems and demands a ransom for their decryption. This ransomware appends filenames with the extension .{victim’s_ID}.hudson, rendering files inaccessible without the decryption key provided only upon payment. Victims will typically notice their files, once named something like example.docx, appearing as example.docx.{victim's_ID}.hudson. The encryption methods employed by Hudson Ransomware are highly sophisticated, likely utilizing a combination of asymmetric and symmetric algorithms to ensure that decryption is impossible without the unique private key. Following encryption, Hudson Ransomware leaves a ransom note named README.TXT on the infected device. This file contains instructions on how to recover the encrypted data, typically warning users not to rename files or attempt third-party decryption, as these actions could result in permanent data loss.

Currently, there are no known decryption tools available for Hudson Ransomware. The complexity of its encryption techniques means that recovery of the encrypted files is near impossible without the attackers’ cooperation, which generally involves paying the ransom—a move we strongly advise against, as it not only funds criminal activities but also offers no guarantee of data recovery. Instead, the best course of action for those affected is to remove the ransomware from their system using a reputable anti-malware tool and then recover data from unaffected backups, if available. Victims are also encouraged to report the incident to local cybercrime authorities. Recovery through third-party decryption tools is often a scam or intermediary service between the victim and the attacker, likely resulting in additional expense with no guarantee of recovery. Regular data backups and stringent cybersecurity practices remain the most effective strategies for mitigating losses from ransomware attacks.

How Hudson Ransomware infects computers

Hudson Ransomware typically infiltrates computers through deceptive methods that exploit user behavior. This malicious software is often delivered via phishing emails, which may contain infected attachments or links designed to trick recipients into downloading the malware. Additionally, Hudson can spread through compromised websites hosting malicious ads or drive-by downloads that automatically install the ransomware without user consent. Cybercriminals also package Hudson with pirated software or use fake software updates to disguise its installation. Once executed, the ransomware quickly encrypts files on the victim’s system, appending a unique extension and leaving a ransom note demanding payment for decryption. To prevent such infections, users should exercise caution with email attachments, verify download sources, and maintain robust security software.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Hudson Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
