How to remove Kruu Ransomware and decrypt .kruu files

2
Kruu Ransomware is a devastating crypto-virus (variation of STOP Ransomware), that uses the AES-256 asymmetrical encryption algorithm to restrict user access to their files without the key. Malware appends .kruu extensions to files make them unreadable and extort ransom for decryption. Unfortunately, due to technical modifications in the newest version file recovery is impossible without backups. However, there are certain standard Windows features and tools, that may help you restore at least some files. File-recovery software may also be useful in this case. In the text box below, there is text message from _readme.txt file, called "ransom note". In this file, malefactors disclose contact information, the price of the decryption, and ways to pay the ransom. Even if you can afford the price of the decryption, there is no purpose to pay the ransom. Hackers rarely respond to victims and there is no method to track the payment as they use cryptocurrency, TOR-network websites and e-mails, and anonymous electronic wallets. There is a tool called STOP Djvu Decryptor, that was able to retrieve the key for older versions of STOP Ransomware. But according to its developers, it is practically useless against .kruu files.

D3adCrypt encrypts system-stored data (with the .d3ad extension) and demands victims to pay a monetary ransom for its return. For instance, a file like 1.pdf will become 1.pdf.d3ad resetting its original icon as well. There is also a ransom note being created (d3ad_Help.txt) explaining to victims how they can return access to files. It is said victims should write an e-mail with their personal ID to the provided d3add@tutanota.com address. In case nobody responds, there is an extra e-mail victim should contact as well (propersolot@gmail.com). Cybercriminals conclude the ransom message with warnings against renaming files, decrypting files on your own, or trying to involve the help of third-party entities. Note that the price for decryption is kept secret until victims establish further communication with cybercriminals. It is also possible for the price to vary depending on how much informational damage victims suffered during encryption. Usually, cyber experts do not recommend paying the ransom - extensive researches show that many extortionists fool their victims and do not provide them with promised decryption tools. Alas, there are no feasible ways to decrypt your data at the moment of writing this article. It may become possible in the future, but no one can say when. You can try some trusted and globally-used tools from our guide below, but there is no guarantee they will be able to actually help.

How to remove Spark Ransomware and decrypt .Spark files

Discovered by MalwareHunterTeam, Spark is a ransomware virus designed to keep files at lock and blackmail victims into paying money to return them. This is done through the so-called encryption process when infections of such use strong military-grade algorithms to generate ciphers. As a result, data becomes no longer accessible to users. People attacked by Spark Ransomware will see their files change to something like this 1.pdf.Spark and reset their icons. After rendering all targetted files restricted, the virus displays a pop-up window containing ransom instructions. Cybercriminals say decryption is impossible without a special private key. This is why victims are guided to purchase the key by contacting developers via their e-mail address (notvalidemailadress.ransom@gmail.com). Swindlers also warn against doing modifications to files shutting down the PC, which may result in permanent data loss and system damage as well. There is a timer, within which, victims should contact developers and pay for decryption. However, extortionists do not specify what will happen after the time expires. Based on other ransomware analyses, many frauds threaten the collected data to be permanently deleted or leaked to dark web resources, though, it does not prove this is the case with Spart Ransowmare as well. It is unfortunate to acknowledge, but you are less likely to find a 100% working decryption tool for .Spark files.
