How to remove BlackHatUP Ransomware and decrypt .BlackHatUP files

What is BlackHatUP Ransomware

BlackHatUP is a variant of ransomware based on the Chaos ransomware. It encrypts data, appends its extension (.BlackHatUP) to filenames, generates a ransom note (read_it.txt), and changes the desktop wallpaper. For instance, it changes 1.jpg to 1.jpg.BlackHatUP, 2.png to 2.png.BlackHatUP, and so forth. BlackHatUP ransomware encrypts files using the AES algorithm. The AES key is then encrypted using the RSA public key contained in the configuration. The ransom note informs the victim that their attempt to execute an unauthorized .exe file has resulted in the permanent loss of their files. It offers a potential solution by suggesting that the files can be recovered if the victim pays a sum of 500 Indian Rupees (INR). The victim is directed to contact “BlackHatUP” on Telegram. To prevent future ransomware infections, it’s crucial to maintain good cybersecurity practices. This includes regularly updating and patching software, using reliable security solutions, avoiding suspicious emails or websites, and regularly backing up important data.

Unfortunately, due to the complex nature of the encryption used by BlackHatUP ransomware, decrypting .BlackHatUP files without the specific decryption key is currently not possible. The AES encryption used is secure and cannot be broken without the corresponding RSA private key, which is only known to the attackers. However, victims are strongly advised not to pay the ransom, as this does not guarantee the recovery of the encrypted files and only encourages the attackers to continue their illicit activities. Instead, victims should report the incident to their local authorities and seek professional advice.

In the event of a ransomware infection, it’s recommended to remove the ransomware from the system using a reliable antivirus or antimalware tool, and then restore the affected files from a recent backup. If a backup is not available, victims may choose to keep the encrypted files in the hope that a free decryptor will become available in the future. It’s also worth noting that some cybersecurity companies and organizations offer services to identify the type of ransomware infection and provide information about it, such as the ID Ransomware website. This can be helpful in keeping track of potential decryption tools or solutions that may be developed in the future.

How BlackHatUP Ransomware infects computers

BlackHatUP ransomware is distributed through various means. Cybercriminals use phishing emails, where malicious attachments or links are delivered to unsuspecting recipients, or malicious ads on compromised websites that automatically download ransomware onto visitors’ computers. They also exploit software vulnerabilities, employ social engineering to trick users into downloading malicious files, and carry out remote desktop protocol (RDP) attacks to gain unauthorized access and deploy ransomware. Additionally, threat actors use P2P networks, torrents, pirated software, cracking tools, and similar channels to distribute malware.

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

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

ZoneAlarm Anti-Ransomware Dashboard

ZoneAlarm Anti-Ransomware Alert

ZoneAlarm Anti-Ransomware Blocked

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. BlackHatUP 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.
