Introduction to KimcilWare Ransomware
KimcilWare Ransomware is a dangerous and destructive form of malware that specifically targets websites which use the Magento e-commerce platform. Its method of attack involves encrypting all files in the targeted servers and adding a .kimcilware extension to each of these compromised files.
How KimcilWare Ransomware Operates
After encrypting the files, the ransomware creates an index.html file containing a ransom-demanding message. The message explicitly states that all the files stored within the server have been decrypted. Victims of this cybercrime are instructed to pay a ransom amounting to 1 BTC to BTC Address: 1859TUJQ4QkdCTexMTUQYu52YEJC49uLV4. The hackers also provide for contact the email: tuyuljahat@hotmail.com.
Distribution Methods
KimcilWare ransomware is primarily distributed via a plethora of methods which include trojans, fake software updates, malicious email attachments, and peer-to-peer (P2P) networks. Insight into these methods can help in exercising caution and mitigating any potential threats.
The Variants of KimcilWare Ransomware
Research has uncovered the existence of another variant of KimcilWare Ransomware. This successor uses a different script to accomplish its destructive encryption. Instead of using the .kimcilware extension, the new variant uses a .locked file extension on the encrypted files. Another significant difference is seen in the mode of communication. As opposed to meddling with the index.html file, it creates a new file, README_FOR_UNLOCK.txt, for its ransom message.
Lack of A Remedy for KimcilWare Ransomware
Despite the potential severity of finding oneself a victim of KimcilWare Ransomware, there currently exists no tool capable of restoring compromised data. As a result, the victims' only remedy lies in restoring their server files and data from a trustworthy backup.
Variants of KimcilWare Ransomware
Research has revealed the existence of another variant of KimcilWare ransomware which uses a different method to encrypt files. Unlike the original version, this variant does not change the index.html file, it rather creates a new file.
Different Encryption Script and Extension
The second variant of KimcilWare ransomware uses a different script to encrypt the server's files. Apart from the change in script, there is a noticeable difference in the file extension added after encryption. This variant does not add the .kimcilware extension seen in the original version; instead, it adds a .locked extension to the encrypted files.
Similarity with Other Ransomware
KimcilWare, like many of its counterparts, aims to infiltrate systems, encrypt stored files, and then demand a ransom from the victims. This modus operandi is shared amongst many ransomware-type viruses including Locky, CTB-Locker, Xorist, Vault, and Cerber.
Notable Differences
Despite these similarities, there exist some notable differences between KimcilWare and the rest. For one, most of the ransomware infections, including those listed herein, are typically designed to target the Windows operating system. On the contrary, KimcilWare targets websites using the Magento e-commerce platform. Also, disparities can be seen in the type of encryption used and the size of the ransom demanded.
Uncertainty following Ransom Payment
Another crucial point to note is that paying the ransom does not guarantee that the files will be decrypted. In fact, there are numerous cases where the cybercriminals do not respond to the victims even after the ransom payment is made. It is thereby advisable not to engage in paying the ransom or contacting the cybercriminals as there remains a high level of uncertainty surrounding the successful retrieval of the compromised files.
Prevention and Protection Against KimcilWare Ransomware
In order to increase safety and lessen the chances of becoming a victim to ransomware like KimcilWare, it's crucial to understand its methods of distribution, the importance of software updating, and exercising caution while handling files and emails from unknown sources. Being extremely cautious when opening files from unrecognizable emails or downloading applications from third-party sources can significantly reduce the risk of a ransomware infection. As malicious email attachments and shady third-party sources are common mediums for ransomware distribution, a strong understanding of these precautions can help deter the threat that these cyber attacks pose.
