What is Kashima Ransomware

Kashima (KashimaWare) is a ransomware program – the type of malicious software designed to encrypt data and demand money for its return. Unlike other infections of this kind, the virus targets specific and quite unusual file formats – .config, .cfg, .js, .NOOB, .lua, .lw, and .tryme as well. It therefore modifies them with the .KASHIMA extension. For instance, a file like 1.js will change to 1.js.KASHIMA, 1.cfg to 1.cfg.KASHIMA and so forth with other affected data. As soon as this process gets done, Kashima displays a pop-up message (KashimaWare WARNING!) accross the whole screen.

KashimaWare WARNING!

KashimaWare WARNING!
WARNING!
Your cfgs have been encrypted by Kashima!
What the HELL is it?
Practice cruiser "Kashima" encrypted your f**king cfg and js. it can't be recovered without this application because they are encrypted with highly strong encryption algorithm, using random key.
How can I recover my cfg
That's easy. You just have to running Nixware loader. this application will detect the process automatically. DO NOT TRY USING FAKE EXE OR TEMRINATE THIS APPLICATION IF YOU DON'T WANT TO BLOW UP THE ENCRYPTION KEY!
Status
Loader Process Status : Not Found
Decryption :Not Approved!

The pop-up message design is similar to the one used by another popular and devastating ransomware virus called Rensenware. Unfortunately, it is unclear what developers want from their victims. There are neither contact nor payment details that victims could use to purchase a special decryptor. This means decrypting data with the help of cybercriminals is completely impossible. Such an absence of payment information most likely says this ransomware is was spread as somebody’s joke or experiment to test how it works before releasing the full version. As a rule, decrypting data without swindlers themselves is quite an undoable task with most file-encryptors. However, since Kashima is supposedly under development, there can be some flaws allowing to decipher the data. You can give it a try using our instructions below or recover your data through backup copies instead. Note that it is a must to delete the infection first and only then attempt to restore or decrypt your files. Follow our tutorial below to get more details on this.

How Kashima Ransomware infected your computer

Ransomware developers use a variety of channels to spread their malware – trojans, unprotected RDP configuration, phishing techniques, fake software installers/updates, backdoors, keyloggers, and dozens of other malicious vectors. Despite such an abundance of methods, many crooks are e-mail spam proponents. They send a buttload of spam messages disguised as legitimate letters. Usually, these letters contain malicious attachments or links designed to install a virus. After interacting with them as said in such letters, the virus will be unleashed and infect a system. You can avoid it by ignoring such messages and deleting them from your inbox. To be more protected against threats like Kashima Ransomware in the future, it is a general rule to be more careful and less naive towards suspicious content you see on the web. Explore our guide below for broader advice and working tools to secure yourself and data as well.

Kashima 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.
