How to remove 24H Ransomware and decrypt .24H files

What is 24H Ransomware

24H Ransomware is a malicious software designed to stealthily infiltrate computer systems and encrypt user files, making them inaccessible. Once executed, it appends the .24H extension to the filenames of affected files, rendering them unusable until recovery measures are taken. The encryption employed by this ransomware is likely based on complex algorithms, though specific details regarding the cryptographic methods remain undisclosed. Upon successful encryption, 24H Ransomware generates a ransom note named ReadME-24H.txt, which is created and placed in every folder containing encrypted files. This note contains instructions for victims, informing them that their data has been encrypted and demanding a ransom payment, typically in Bitcoin, to receive the necessary decryption tool.

When it comes to recovery, there are currently no known decryption tools available for files locked by 24H Ransomware. The encryption is considered robust, and researchers have found no viable methods to reverse it without directly contacting the cybercriminals behind the attack—an action that is highly discouraged due to the risk of further financial loss and deception. Victims are advised against paying the ransom, as there is no guarantee that they will receive the promised decryption tools or that the hackers will even respond. The best strategy for dealing with ransomware like 24H is to maintain regular and secure backups of important data, allowing for restoration without succumbing to extortion. Restoring files from backup is far more effective than attempting to decrypt the .24H files, especially given the current lack of available decryption solutions.

How 24H Ransomware infects computers

24H Ransomware typically infiltrates computers through a variety of deceptive tactics, capitalizing on user carelessness and poor cybersecurity practices. One common method involves the use of malicious email attachments, often disguised as legitimate documents or invoices, which, when opened, execute scripts that download and install the ransomware. Additionally, cybercriminals exploit unofficial software download sources, such as torrent sites or free software hosting platforms, where they bundle the ransomware with seemingly harmless applications. Trojans may also be employed as a backdoor, allowing 24H to bypass security measures and gain access to the system. Another avenue for infection is through fake software update tools that trick users into unwittingly installing the malware while believing they are getting essential updates. Ultimately, a lack of awareness and vigilance among users significantly increases the risk of falling victim to such ransomware attacks.

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. 24H 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.
