How to remove Allarich Ransomware and decrypt .allarich files

What is Allarich

Allarich Ransomware is a sophisticated form of ransomware designed to encrypt files on infected systems, rendering them unusable until a ransom is paid. This malware appends the .allarich extension to the filenames of encrypted files, making it easy to identify but challenging to recover without the decryption key. For instance, a file named photo.jpg would be renamed to photo.jpg.allarich once encrypted. Upon successful encryption, the ransomware generates a ransom note named README.txt, typically placed in directories containing encrypted files. This note usually instructs the victim to contact the cybercriminals via a provided email address and warns against using third-party decryption services, albeit without mentioning the exact decryption method or ransom amount, emphasizing that the cost depends on the promptness of the victim’s response.

Despite the severity of the attack, no publicly available decryption tools can currently decrypt .allarich files without involving the attackers. The encryption employed by Allarich is notably robust, using advanced cryptographic algorithms that are not easily broken without a corresponding decryption key, typically held exclusively by the ransomware operators. As of now, victims of Allarich Ransomware have limited options for recovering their files, underscoring the importance of having reliable data backups and up-to-date antivirus software. Efforts such as the “No More Ransom” project may offer broader decryption support for some ransomware variants, but they do not currently cover Allarich, further illustrating the necessity of preventive measures rather than relying on post-infection solutions.

How Allarich Ransomware infects computers

Allarich Ransomware primarily infects computers through phishing and social engineering tactics, where malicious files are disguised as or bundled with legitimate-looking content. These files often come in various formats such as RAR, ZIP archives, executables, Microsoft Office documents, PDFs, and JavaScript files. Once a user opens these infected files, the ransomware payload is executed, initiating the encryption process. Additionally, Allarich can spread via drive-by downloads from dubious websites, malicious email attachments, deceptive online ads, and even through compromised network shares and removable storage devices like USB flash drives. This multifaceted approach makes it critical for users to exercise caution when interacting with unsolicited emails and downloads, and to regularly update their security software to mitigate the risk of such infections.

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. Allarich 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.
