How to remove Krypt Ransomware and decrypt .helpo files

What is Krypt Ransomware

Krypt Ransomware is a malicious program that operates as a file-locking Trojan, demanding a ransom from its victims in exchange for the decryption of their compromised data. Once it infiltrates a system, it utilizes sophisticated encryption algorithms to lock files and render them inaccessible. A distinctive characteristic of this ransomware is its renaming mechanism; it alters the original file names to a random character string and appends them with the .helpo extension. For instance, a file initially named photo.jpg might be transformed into Gs2Rt9e.helpo after encryption. The encryption deployed by Krypt Ransomware is typically complex, often involving robust algorithms that significantly limit the chances of decryption unless the attackers’ private decryption key is procured. This level of encryption ensures that files remain securely locked, amplifying the pressure on victims to comply with the ransom demands. After encrypting the files on a victim’s machine, Krypt Ransomware creates a ransom note in a text file named HowToRecover.txt, placed conspicuously on the desktop and potentially other locations to maximize visibility.

This note informs victims that their files have been encrypted and provides instructions on how to contact the attackers, commonly through anonymous communication channels. It further warns against seeking help from data recovery companies or using third-party decryption tools, implying that such actions could damage the files permanently. Unfortunately, as of now, there are no publicly available decryption tools capable of recovering files affected by this ransomware without the attackers’ original decryption key. Consequently, victims often find themselves at a crossroads, balancing ethical dilemmas and the potential financial loss against the desperate need to recover invaluable personal or business data. It’s crucial to note that the decryption of .helpo files remains reliant on either obtaining the attackers’ cooperation, which is highly discouraged, or restoring data from previously established safe backups.

How Krypt Ransomware infects computers

Krypt Ransomware primarily infiltrates computers through a combination of deceptive tactics and vulnerabilities in user behavior. The malware often masquerades as legitimate files or is bundled with seemingly innocuous downloads from untrustworthy sources like unofficial file-hosting sites and P2P networks. Phishing emails also serve as a common vector, where malicious attachments or links, disguised as urgent communications, trick users into executing the ransomware. Once activated, the ransomware rapidly encrypts files, leaving victims with files bearing the “.helpo” extension and a ransom note demanding payment for decryption. Additionally, Krypt can spread through compromised networks and removable storage devices, further emphasizing the importance of maintaining robust cybersecurity practices, such as updated antivirus software and cautious internet usage. The pervasive nature of Krypt underscores the critical need for user vigilance and comprehensive security measures to mitigate the risk of infection.

How to decrypt and restore .helpo files

Use automated decryptors

Download Kaspersky RakhniDecryptor

Use the following tool from Kaspersky called Rakhni Decryptor, that can decrypt .helpo files. Download it here:

Download RakhniDecryptor

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 .helpo 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 Krypt 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 Krypt 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. Krypt 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.
