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.
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 employ an information gathering module. During this process, the malware collects information about the infected system and user and send the gathered data to a remote server. From there, a couple of malicious files will then be added into 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 in 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:
“Hello, dear friend.
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]”
How is the malicious payload of WALAN ransomware spread online?
WALAN ransomware, just like a typical ransomware, proliferate using malicious spam email campaigns that contain the malicious payload. Once the infected attached file is downloaded and opened, it will connect to its remote Command and Control (C&C) server which is the one responsible for downloading and attaching the crypto virus. This is why you need to be cautious about the files you download over the web and make sure that these files came from legitimate and reliable sources.
