Btcware is a popular ransomware family counting a number of versions since 2017. The ransomware developed by this group of cybercriminals has evolved into using stronger and more secure algorithms. Since there are many versions of Btcware, the world has seen many types of encryption throughout its span of existence. For example, older versions used to apply old RC4 algorithms, until the rise of AES-192 and AES-256 in later samples. The same story goes with extensions. Each version of Btcware involves a brand new extension different from others. Traditionally, once the encryption is done, ransomware programs create a text note file containing instructions to recover your data. The name of a note also depends on which version pounced your system, but usually, it is #_HOW_TO_FIX_!.hta or READ ME.txt. Inside of this note, cybercriminals use clumsy introductions ostensibly meant to explain what happened. Then, they ask to contact them via attached e-mails to get in further touch. Once done, users will receive a set of instructions to buy the decryption software. Some versions of Btcware require 0.5 BTC for data encryption. If you do not have this money to pay, there is a chance that extortionists will threaten you with permanent loss or inappropriate data abuse. In most cases, files encrypted with AES algorithms are hard to decrypt unless you purchase the private key held by cybercriminals themselves.

The 0xc00000e9 code is a BSOD (Blue Screen of Death) error frequently-seen on Windows 10. The issue results in an unexpected shutdown with a recovery screen displaying: "There was a problem with a device connected to your PC. An unexpected I/O error has occurred. Error code: 0xc00000e9". The window also says the possible reason for the error appearance lies in the wrong connection of external devices. This is the truth, especially when it was abruptly removed from the input port. Whenever Windows 10 suspects a risk of damage, it shuts down your PC to prevent unhealthy conditions. However, if you keep running into the same problem multiple times, this may cause future damage to your devices. If you are sure there are no accidental manipulations done from your side, more likely there are some independent problems like wrong configuration, hard drive problems, lack of drivers, an unstable connection of plugged devices, missing or corrupted files. Below, we have gathered a list of the most popular and effective solutions to stop the 0xc00000e9 error.

The 0x80080008 error code is related to windows updates. A number of people reported the problem appears after trying to check for updates. Some users managed to find a temporary solution using Windows Troubleshooter, however, the problem continued to press the line after a simple reboot stating the "Service registration is missing or corrupt" message. As a result of error inspection, experts found the reason behind 0x80080008 appearance is in Wups2.dll (the file included in the latest version of Windows Update) that was incorrectly installed. Apart from the prime reason we mentioned, there are grounds to believe that 0x80080008 may be related to the scarcity of files, wrong service configuration, and so forth. Below, we will show how to get rid of this annoying problem and continue receiving Windows Updates as usual.

Ziggy is a new ransomware-infection recorded in December 2020. The virus sneaks into your system disabling all protectionary layers on your PC. Then, it gets the job done by running data encryption with AES256-GCM and RSA-4096 algorithms. These ensure strong encryption, which is hard to decipher. Before going deeper into details, it is important to say that there are two versions of Ziggy Ransomware. The first uses the .ziggy extension along with victims' ID and cybercriminals' e-mail to configure the data. The later version of Ziggy Ransomware detected recently started involving the same string of information but changed the extension at the end to .optimus. For example, a file like 1.docx would change to 1.docx.id=[88F54427].email=[khomeyni@yahooweb.co].ziggy or 1.docx.id[B68A285D].[sikbeker@tuta.io].optimus depending on which version affected your PC. Following successful encryption, the malicious program creates a text file containing decryption instructions. The name of the files can vary from version to version, so there is no commonly-used, but initially, it was called ## HOW TO DECRYPT ##.exe.

Matroska Ransomware is a malicious piece aimed at data encryption. Matroska used to show its activity a couple of years ago until it went dormant. Within some time, it started a series of new infections on users' PCs. Whilst older examples of Matroska applied the .HUSTONWEHAVEAPROBLEM@KEEMAIL.ME, .happyness, .encrypted[Payfordecrypt@protonmail.com], .nefartanulo@protonmail.com extensions to encrypted files, recent attacks of this ransomware showed the new .siliconegun@tutanota.com extension being involved. Depending on which version impacted your system, a file like 1.mp4 will change to 1.mp4.happyness or 1.mp4.siliconegun@tutanota.com at the end of encryption. Once this process is finished, the virus goes further and creates a text file (HOW_TO_RECOVER_ENCRYPTED_FILES) with decryption instructions. Alike other ransomware infections, Matroska asks victims to pay a fee. The amount may vary from person to person, however, we do not recommend buying their software. Luckily, experts found that Dr.Web (leading antimalware software) is able to decrypt your data legitimately and risk-free. Before doing so, you've got to make sure you deleted Matroska Ransomware from your computer. Only then you can use third-party tools to recover the data. For more information on both removal and data decryption, follow the article down below.

DearCry Ransomware is a dangerous virus, which targets the encryption of personal data. Such malware makes everything sure that there is no way to decrypt the locked files. Knowing that, cybercriminals offer their own solution - to buy the decryption key stored on their servers. Because most users can find no way out of the trap, they agree on paying the ransom to recover the data. Unfortunately, this is a serious risk proven by multiple victims who did not receive the promised decryption. This is why it is better to delete DearCry Ransomware and reclaim your files via backup or data-recovery tools. If you are the one having files changed with the .crypt extension, which was then accompanied by the ransom note creation (readme.txt), chances are you are infected with DearCry Ransomware.

Developed on Node.js, JoJoCrypter is a malicious program that functions as a data-encryptor. A thorough investigation conducted recently shows there is a .jojocrypt extension assigned to each of the files. To illustrate, a non-encrypted 1.mp4 will turn into 1.mp4.jojocrypt as a result of infection. Along with this, it is also known that JojoCrypter uses RSA-2048 and AES-192 algorithms to cipher innocent files. It also creates a short ransom note how to recover your files.txt with following content. Unfortunately, the decryption with third-party tools appears to be an impossible task. The encryption chains are too strong and flawless to crack. This is why the only option (apart from paying the ransom) is to recover your files using backup or data-recovery tools. Otherwise, you will be forced to pay for the keys proposed by cybercriminals, which is mentioned in the ransom note dropped on your PC after encryption. Swindlers are not using too many words for describing what happened, instead, they attach their e-mail address to be contacted for further instructions.

Parasite is one of the newest ransomware samples detected by cyber experts in recent days. Alike other malware of this type, Parasite encrypts personal data and demands money for the decryption. However, it was found that Parasite has a significant flaw - it encrypts data with the wrong cipher and overwrites data with 256 bytes. This means that all data encrypted by Parasite loses its value completely, simply because it gets replaced with empty space. For example, a word file, which weighs megabytes of data will decrease and start weighing mere 256 bytes. Such a bug instantly shows that Parasite is not able to decrypt your files, simply because they become damaged. Of course, they claim to decrypt them in HOW_CAN_GET_FILES_BACK.txt ransom note (alternatively @READ_ME_FILE_ENCRYPTED@.html or info.hta), which is created after encryption, but it does not make any sense due to the above-mentioned.
