How to remove Biobio (Kasper) Ransomware and decrypt .biobio files

What is Biobio Ransomware

Biobio Ransomware is a variant of a known ransomware threat, specifically identified as a mutation of the Kasper Ransomware. It functions primarily by encrypting data on the victim’s system, subsequently appending its own specific syntax to the filenames, severely complicating file access without the decryption keys. This ransomware appends the extension .biobio to each compromised file, along with the victim’s unique ID and the attackers’ email address, which makes affected data quickly identifiable yet inaccessible. Utilizing robust, modern cryptographic methods, typically an unbreakable encryption algorithm, the malware encrypts files with either symmetric or asymmetric keys, making decryption without the attackers’ decryption key practically unfeasible. After encryption is completed, the ransomware generates a ransom note in a text file named biobio ransmoware.txt, which is strategically placed on the victim’s desktop and in other prominent directories. This note details steps for the victim to contact the attackers via email or Telegram for decryption instructions, discouraging the use of third-party decryption attempts.

Despite the critical nature of the situation, decryption tools specifically for Biobio ransomware are currently unavailable to the public, underscoring the importance of preventative cybersecurity measures. Decrypting .biobio files without the cybercriminals’ cooperation remains impractical due to the complexity and robustness of the encryption methods employed. Victims are advised against paying the ransom as there is no certainty that the attackers will provide the requisite decryption keys upon receipt of payment. Thus, it’s crucial to focus on alternative recovery methods such as restoring corrupted files from available backups, if they exist, or utilizing reputable data recovery tools that might salvage portions of the encrypted data. Security experts also emphasize the importance of immediately isolating infected devices to prevent further data loss and reporting the incident to the appropriate authorities. Regularly backing up data and employing advanced antivirus solutions can mitigate the impact of such ransomware attacks, preserving data integrity in the absence of decryption solutions.

How Biobio Ransomware infects computers

Biobio Ransomware, also known as Kasper Ransomware, infiltrates computers primarily through deceptive methods such as phishing emails and malicious attachments. Cybercriminals often disguise these emails to appear legitimate, encouraging users to open attachments or click on links that trigger the ransomware download. Once executed, Biobio Ransomware begins encrypting files on the infected system, appending them with a new extension and creating a ransom note demanding payment for decryption. The ransomware can also spread through drive-by downloads on compromised websites and via malicious ads, exploiting vulnerabilities in outdated software to gain access. Additionally, Biobio Ransomware might use loader or backdoor-type trojans to enter systems, further complicating its detection and removal. To prevent such infections, users should maintain updated antivirus software, avoid suspicious emails and websites, and regularly back up important data.

There is no purpose to pay the ransom because there is no guarantee you will receive the key, but you will put your bank credentials at risk.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .biobio files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with Biobio Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

How to protect computer from viruses, like Biobio Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

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. Biobio 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.
