Nifr Ransomware, being a part of STOP Ransomware (DjVu Ransomware) family, is an elaborate encryptor virus, that encrypts user's files and makes them inaccessible. Malware uses an unbreakable AES (Salsa20) encryption algorithm, and decryption is only possible in 2-3% of cases. It first generates a unique AES-256 encryption key for each file it encrypts, which is used to encrypt the file's contents. This process is known as symmetric encryption, as the same key is used to encrypt and decrypt the file. After encrypting the file with the AES-256 key, Nifr Ransomware then encrypts the AES-256 key with an RSA-1024 public key, which is included in the ransomware's code. This process is known as asymmetric encryption, as it uses different keys for encryption and decryption.Recent version of STOP Ransomware adds following suffix or extension: .nifr. Corresponding virus variation received names: Nifr Ransomware. After encrypting, the ransomware creates _readme.txt file, that specialists call "ransom note", and below you can get acquainted with the contents of this file. The note contains instructions on how to contact the ransomware operators and pay the ransom in order to receive the decryption key. The ransomware is typically distributed through spam emails, fake software updates, and software cracks/keygens. It is important to note that paying the ransom is not recommended, as it encourages the criminals and there is no guarantee that the decryption key will be provided.

Bigcaptchahere.top is a malicious website that uses push notifications to bombard users with unwanted ads, pop-ups, and notifications. Bigcaptchahere.top exploits push notifications to deliver unwanted ads and pop-ups to users even when they are not browsing the web. Once the user enables push notifications on their device, the site sends a steady stream of notifications containing ads, links, and other spam content. This technique allows the site's creators to monetize their traffic by generating revenue from ad clicks and by redirecting users to affiliate websites. The notifications can be highly intrusive and difficult to disable, leading to a frustrating and disruptive user experience. In some cases, Bigcaptchahere.top may also install malware on the user's device, leading to further damage and potentially compromising sensitive information. The website is usually promoted through various deceptive tactics such as fake software updates, free downloads, or by using social engineering tactics to trick users into visiting the site. Once the user visits the site, they are prompted to enable push notifications to access the site's content. Once the user accepts, the site starts displaying unwanted push notifications on their desktop, mobile phone or tablet. Follow our guide below to remove Bigcaptchahere.top ads and notifications from Google Chrome, Safari, Firefox, Edge on Windows, Mac, Android, iOS.

D7k is the name of a recently-discovered ransomware infection. Alike other infections within this category it is designed to encrypt system-stored data and extort money for its decryption from victims. During encryption, all targeted files will get .D7k extension and reset their icons to blank. As a result, users will no longer be able to access their files, even after manually removing the newly assigned extension. Once successful encryption gets to its finish, the virus creates a text file called note.txt, which contains decryption guidelines. The note contains a short text demanding 500$ dollars for file decryption. This amount is to be sent to the bitcoin wallet attached by cybercriminals. The message does not include any communication channels, which makes the decryption process ambiguous. Paying the ransom is not recommended because many cybercriminals fool their victims and do not send promised decryption means in return. However, in this case, it appears to be even riskier due to the lack of any communication channels to contact the extortionists. Despite this, cybercriminals are usually the only figures able to unlock access to data completely and safely. The moment this article was written, no public third-party tools are known to bypass the ciphers assigned by D7k Ransomware. Decryption using third-party tools or windows shadow copies using is possible only in rare cases when the ransomware is flawed or accidentally faulted during its operation for whatever reason. Otherwise, the only ways to recover your data are either by collaborating with ransomware developers or retrieving data from existing backup copies. Backups are copies of data stored on external devices such as USB drives, external hard drives, or SSDs.

Jycx Ransomware (in other classification STOP Ransomware or Djvu Ransomware) is harmful malware, that blocks access to user's files by encrypting them and requires a buyout. It was released in the last days of March 2023 and hit tens of thousands computers. The virus uses an unbreakable encryption algorithm (AES-256 with RSA-1024 key) and demands a ransom to be paid in Bitcoins. However, due to some programming mistakes, there are cases when your files can be decrypted. A version of STOP Ransomware, that we are considering today, adds .jycx extensions to encrypted files, and therefore got the name Jycx Ransomware. After the encryption, it presents file _readme.txt to the victim. This text file contains information about the infection, contact details, and false statements about decryption guarantees. The following e-mails are used by malefactors for communication: support@freshmail.top and datarestorehelp@airmail.cc.

Hairysquid is a newly-discovered variant of the Mimic ransomware. After penetration, it modifies the Windows GroupPolicy, deactivates protection by Windows Defender, and disables other Windows features to exclude any deterrence of its malicious activity. The goal of this infection is to encrypt access to system-stored data and demand money for its decryption. During the encryption processes, the virus attaches the .Hairysquid extension to all affected files. Once done, a file like 1.pdf will turn to 1.pdf.Hairysquid and change its icon eventually. Instructions on how to decrypt the blocked data are presented within the READ_ME_DECRYPTION_HAIRYSQUID.txt note, which gets created alongside successful encryption. Overall, it is said victims have been attacked by ransomware, which encrypted their data. In order to reverse the damage and get back the files, victims have to contact the swindlers via one of the provided communication channels (TOX messenger, ICQ messenger, Skype, and email) and pay for decryption in Bitcoins. The price for decryption is said to be calculated based on the number and potential value of encrypted data. In addition, it is also allowed to test decryption for free by sending 3 locked files to cybercriminals. Alas, it is usually impossible to decrypt blocked data without the involvement of cybercriminals themselves.

New.copperforged.top is a rogue website that employs social engineering techniques to promote potentially unwanted content. The website has been observed to demand clicking on the "Allow" button (in the pop-up box) in order to confirm that you are not a robot. Depending on certain factors (e.g., geolocations, previous browsing activity, etc.) users can also be told to allow this action in order to access a certain webpage, download a file, watch a video, or something similar. In the majority of cases such messages are fake and simply meant to deceive inexperienced users into enabling push notifications. Note that push notifications are a legitimate and useful feature allowing websites to send notifications about new updates in a convenient way right to the desktop. However, websites like New.copperforged.top exploit this functionality to supply users with compromised content. Such content is likely to display fake/click-bait information and lead to explicit or malicious resources. If you accidentally became a victim of New.copperforged.top or similar page, follow our guide below to abort the assigned modifications. In addition, if your browser repeatedly displays this (or other random pages) without your consent, it is possible that your system is currently infected with adware. Whatever your case, you will be able to remove the unwanted changes using our step-by-step guidelines down below.

Jyos Ransomware (a.k.a Djvu Ransomware or STOP Ransomware) encrypts victim's files with Salsa20 (stream encryption system) and appends one of the hundreds of possible extensions, including the latest discovered .jyos. This one appeared in the very end of March 2023 and infected thousand computers worldwide. STOP is one of the most active ransomware today, but they hardly talk about it. The prevalence of STOP is also confirmed by the extremely active forum thread on Bleeping Computer, where victims seek help. The fact is that this malware attacks mainly fans of pirated content, visitors to suspicious sites, and is distributed as part of advertising bundles. There is a possibility for successful decryption, however, to date, there are more than two hundred STOP Ransomware variants that are known to researchers, and such a variety significantly complicates the situation.
