What is Koxic Ransomware

Discovered by Tomas Meskauskas, Koxic is determined to be a ransomware infection that operates by encrypting PC-stored data. In other words, the majority of files like photos, videos, music, and documents will be blocked by the virus to prevent users from accessing them. All files encrypted also get new .KOXIC or .KOXIC_PLCAW extensions. This means encrypted files like 1.pdf will change to 1.pdf.KOXIC or 1.pdf.KOXIC_PLCAW. The same pattern will be applied to residual data encrypted by ransomware. After getting things done with encryption, the virus creates a text note that explains ransom instructions (WANNA_RECOVER_KOXIC_FILEZ_PLCAW.txt).

WANNA_RECOVER_KOXIC_FILEZ_PLCAW.txt

Hello, all your important files are encrypted and sensitive data leaked.
To decrypt your files and avoid other unpleasant things you need to buy special decryption tool.
Contact us via koxic@cock.li or koxic@protonmail.com and tell your UserID.
This is the only way to decrypt your files and avoid publi? disclosure of data .
Do not try to use third party software (it may corrupt your files).
We respect black market rules. We can confirm the ability to decrypt your files (and of course the evidence of the leak ),
Send us several unimportant files (do not try to deceive us).
Your UserID (send it to us for decryption):
{redacted}

These instructions state victims should contact developers via koxic@cock.li or koxic@protonmail.com e-mails with their personal ID. This ID can be found attached to the ransom note. If there is no such being visible, there is a chance some version of Koxic Ransomware that infiltrated your system is still under development and being tested. After establishing successful contact with cybercriminals, you will be given further instructions to buy the decryption tool for unlocking your data. In addition to that, Koxic developers say they can publish your data on black markets in case you refuse to follow their requests. Depending on whether you are an individual or business user, Koxic developers may set different amounts for buying decryption. Usually, this sum can vary from hundreds to thousands of dollars making most victims break a sweat. Whatever the case, trusting fraudulent victims is always a risk as they can fool you and not send any decryption tools even after paying the ransom. For now, the best way to recover your data is by using backup copies if such were created and stored on external devices prior to the infection. Trying some decryption tools by third-party vendors is also an option, but nobody can guarantee your files will be eventually decrypted and safe. Encryption ciphers assigned by ransomware infections may be very sophisticated, which makes their decryption an arduous challenge. Despite this, Koxic Ransomware has to be removed from your system to prevent further encryptions and spreads onto neighboring networks. Follow our guide below to do this and learn about potential recovery methods that can restore your data.

How Koxic Ransomware infected your computer

Before moving on to distribution techniques, it is worth mentioning that ransomware researchers have found that Koxic Ransomware may bring the Azorult Spyware, which is a trojan running collection of passwords, credentials, and other important data. Koxic itself and other infections of similar type are usually spread through a variety of channels like fake software cracking tools and updates, e-mail spam messages with malicious attachments or links, backdoors, keyloggers, unreliable software, and many other suspicious vectors as well. Statistically, most ransomware infections happen when users open fake e-mail messages that contain attached files of .docx, .pdf, .exe, .zip, .rar, or .js formats. Downloading and accessing these files may be a huge risk because they may be scripted for the installation of malware. This is why e-mail services have filtering algorithms that sort unwanted stuff putting it into the “Spam” folder. In most cases, successful installations of malware capitalize on inexperienced and uncareful users that download whatever they see on the web. This is why it is advised to raise your awareness whilst downloading or surfing through content around the Internet. Below, we have prepared a full-fledged guide to help you with the removal as well as protection against threats like Koxic Ransomware in the future.

Koxic 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
