Kaenlupuf virus Removal Guide

What is Kaenlupuf ransomware virus?

What do we know about Kaenlupuf ransomware virus so far?

Today we are going to present a Malaysian ransomware[1] called Kaenlupuf virus. This suspicious and malicious program seems to be in the development process at the moment, but there’s no doubt that it is going to be improved and distributed on a much larger scale shortly[2]. The ransomware name stands for KAsi ENkrip LU PUnya File. The ransomware claims to be using a RSA-2048 encryption algorithm to corrupt files on the target computer, and this cryptography method[3] is known to be one of the most secure ones. Once files are encrypted, there are barely any chances to restore them without having a decryption key. The ransomware authors have it, so they ask the victim to pay a ransom of 1 BTC to their Bitcoin wallet. The ransom note that the virus creates after the encryption procedure says that the computer user “was chosen to be among the ones who got their files protected from external threats.” The criminals ramble about a special package available for an affordable price of 1 BTC[4] that the victim needs to purchase, while in reality, these crooks are just asking for a ransom of approximately 1170 USD. Below, you can see the ransom note (written in Malaysian language):

It goes without saying that you shouldn’t pay ransomware crooks the money they don’t deserve. Instead, we suggest removing the virus using anti-malware tools, for instance, FortectIntego, and recovering your files from a backup. Besides, malware analysts might successfully reverse this piece of malware and create a free decryption tool anytime soon, so we suggest you stay patient. You should start Kaenlupuf removal by rebooting your PC into Safe Mode with Networking. You can find full and comprehensive instructions on how to remove Kaenlupuf ransomware right below the article.

How can you get infected with ransomware virus?

Ransomware viruses are mostly distributed via deceptive email messages, but you can also become a victim of a ransomware attack due to RDP attack[5] or in case you have some outdated software on your PC, and you like to browse through shady Internet websites without having a decent anti-malware or antivirus software on your computer system. This way, your security vulnerabilities in the software you have can be easily exploited by attackers. We suggest you to protect your files in advance by creating a data backup, installing a good security software, and staying away from suspicious content online. Of course, you should also make sure that software you have is up-to-date (especially Flash or Java).

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
