How to remove Novalock Ransomware and decrypt .novalock files

What is Novalock Ransomware

Novalock Ransomware is a malevolent strain of ransomware belonging to the notorious GlobeImposter family. Typically targeting business networks, this malware encrypts files on compromised systems and appends them with the .novalock file extension, effectively rendering the files unusable without the decryption key. For example, photo.jpg would be altered to photo.jpg.novalock, instantly indicating a breach. Under the hood, Novalock employs a hybrid encryption scheme, utilizing both RSA and AES algorithms. This combination ensures a highly secure encryption process, significantly complicating efforts to decrypt without the proper key. Once the encryption is complete, a ransom note titled how_to_back_files.html is generated on the affected system. This note is strategically placed in folders containing encrypted files, warning victims that the attacker has accessed their network, encrypted critical data, and stolen information that may be leaked publicly if the ransom is not paid.

Currently, there are no universally available decryption tools specifically for Novalock, primarily due to the robust nature of the encryption methods it uses. Although free decryption tools exist for other ransomware families, the complexity of Novalock’s encryption poses a significant challenge for security experts. This means that victims are often left with limited options for recovering their files without contacting the attackers. It is crucial to emphasize that paying the ransom does not guarantee the retrieval of decryption keys, as cybercriminals may choose not to uphold their end of the deal. Users must instead focus on preventative measures, such as maintaining regular data backups on offline or cloud services. For those without backups, exploring reputable data recovery tools might offer some recourse, although success rates vary. Until an official decryption tool is developed, restoring systems from backups remains the safest and most effective strategy against Novalock’s crippling impact.

How Novalock Ransomware infects computers

Novalock Ransomware, part of the GlobeImposter family, primarily infects computers through deceptive social engineering tactics and malicious distribution channels. Cybercriminals often employ phishing emails that contain infected attachments or links, masquerading as legitimate communications to trick users into downloading the malware. Once the attachment is opened or the link is clicked, the ransomware is executed, encrypting files and appending the “.novalock” extension to them. Additionally, Novalock can spread through compromised websites, malvertising, and file-sharing networks where infected files are disguised as genuine software or media content. The ransomware can also propagate through network vulnerabilities and removable storage devices, making it crucial for users to maintain robust security practices and avoid downloading software from unofficial sources. The attackers behind Novalock further exploit victims by threatening data leaks, compelling them to pay the ransom for decryption tools, although payment does not guarantee data recovery.
