What is WALAN ransomware? And how does it implement its attack?

WALAN ransomware is one of the latest crypto-viruses discovered recently. It uses an extension of “.WALAN” in marking its encrypted files. Like other crypto-virus, it is created to lock valuable files in a targeted computer, leaving them unusable and inaccessible to users. It urges users to recover files by contacting the given email address at [email protected]. However, doing so is definitely not advised as you could only end up losing money for nothing.

WALAN Ransomware

Once the WALAN ransomware attack takes place, a series of malicious activities will be implemented on the targeted computer. It starts by placing its malicious payload into a system folder which is the one to employs an information-gathering module. During this process, the malware collects information about the infected system and user and sends the gathered data to a remote server. From there, a couple of malicious files will then be added to the computer which helps in keeping the crypto-virus from getting detected by any program in the computer like antivirus programs. Some of these malicious files are also responsible for modifying the Windows Registry that keeps the malware running on every system boot.

Following these changes, WALAN ransomware will look for files to encrypt and locks them using a strong encryption algorithm and adds the .WALAN extension to the encrypted files. Moreover, it will drop a file named “DECRYPT_INFO.txt” which contains the following message:

All your files are encrypted with a unique key.
Are you sure you want to recover all your files?
Write us an email: [email protected]
Enter your unique ID in the message: [redacted 10 lowercase hex]”
