What is LockBit 4.0 Ransomware

LockBit 4.0 represents the latest iteration in the LockBit ransomware family, known for its highly automated and fast encryption processes. This ransomware operates as part of a Ransomware-as-a-Service (RaaS) model, allowing affiliates to deploy the malware against targets in exchange for a share of the ransom payments. LockBit 4.0 Ransomware is notorious for its efficiency and for incorporating evasion techniques that enable it to bypass security measures and encrypt files undetected. Upon successful infection, LockBit 4.0 appends a unique file extension to encrypted files, which has been observed to vary with each campaign. An example of such an extension is .xa1Xx3AXs. This makes the encrypted files easily identifiable but inaccessible without decryption keys. The ransomware uses a combination of RSA and AES encryption algorithms. AES is used to encrypt the files themselves, while RSA encrypts the AES keys, ensuring that only the attacker can provide the decryption key. LockBit 4.0 generates a ransom note named xa1Xx3AXs.README.txt or a similarly named file, which is placed in each folder containing encrypted files. This note contains instructions for contacting the attackers via a Tor website and the amount of ransom demanded, often in cryptocurrencies. The note may also include threats of leaking stolen data if the ransom is not paid, a tactic known as double extortion. This article provides an in-depth analysis of LockBit 4.0 Ransomware, covering its infection methods, the file extensions it uses, the encryption standards it employs, the ransom note details, the availability of decryption tools, and guidance on how to approach the decryption of files with the extension “.xa1Xx3AXs”.

As of the last update, there are no universally available, free decryption tools capable of decrypting files encrypted by LockBit 4.0, especially those with the .xa1Xx3AXs extension. The complexity of the encryption method used makes it virtually impossible to decrypt the files without the unique key held by the attackers. Given the absence of reliable decryption tools for LockBit 4.0, victims are faced with limited options:

Contacting law enforcement and cybersecurity professionals: They may provide advice or assistance and are crucial for investigating the attack.
Backups: Restoring files from backups is the most reliable method to regain access to encrypted data, assuming the backups were not compromised.
Negotiation: While not recommended due to ethical and security reasons, some organizations choose to negotiate with the attackers. However, this does not guarantee the return of data and can fund further criminal activity.
