Qoqa Ransomware (that is a part of a large family of STOP/Djvu Ransomware) is an obnoxious virus, that encrypts files on computers using the AES encryption algorithm, makes them unavailable, and demands money in exchange for so-called "decryptor". Files processed by the latest version of STOP Ransomware, in particular, can be distinguished by .qoqa extensions. The analysis showed that the cryptographic installer loaded with the "crack" or adware is installed under an arbitrary name in the %LocalAppData%\ folder. When executed, it loads four executable files there: 1.exe, 2.exe, 3.exe and updatewin.exe. The first of them is responsible for neutralizing Windows Defender, the second is for blocking access to information security sites. After the malware is launched, a fake message appears on the screen that says about installing the update for Windows. In fact, at this moment, almost all user files on the computer are encrypted. In each folder containing encrypted documents, a text file (_readme.txt) appears, in which attackers explain the operation of the virus. They offer to pay them a ransom for decryption, urging them not to use third-party programs, as this can lead to the deletion of all documents.

A number of users raised concerns towards the 0xc190011f error, which appears when trying to download and install new Windows updates. This issue has mostly been evident in affecting Windows 10 users. As a rule, the error is accompanied by the following message: "There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: [update name] – error 0xc190011f". The most common reasons for its appearance are usually rare system update glitches, corrupted integral file elements, faulty Windows update components, incorrect regional settings, or third-party software conflicts. If you are facing the 0xc190011f issue, it is likely that you will fix it by the end of this guide. Simply try each solution in the sequence below until the issue becomes resolved eventually.

Roghe is a ransomware virus targeting personal data of victims. After the malware infects a targeted system, it starts encryption of potentially important files making them inaccessible until a decryption key is retrieved. During the encryption process, Roghe Ransomware assigns the .enc extension to infected files. For instance, a file like 1.pdf will turn to 1.pdf.enc and so forth with other affected files. Once all files become enciphered, the virus changes the desktop wallpapers and force-opens a pop-up window that features decryption guidelines. The text featured on newly-assigned wallpapers lets users know they have been infected and encourages them to follow instructions from the opened pop-up window. In addition, it also features a QR code leading to more information about the malware. The "Roghe Decryptor" window says victims have 15 minutes to retrieve the key and paste it for unlocking access to files - otherwise, the encrypted files will be deleted forever. It also says that within 20 minutes operating system will be inaccessible, essentially becoming locked.

New wave of STOP Ransomware infection continues with Qowd Ransomware, that appends .qowd extensions. STOP Ransomware was first detected in 2018 and has since evolved into one of the most prevalent types of ransomware. Those ".qowd" extensions are added to encrypted files in the end of February 2023. This tricky virus uses the AES encryption algorithm to encode users' important information. As a rule, Qowd Ransomware attacks photos, videos, and documents - data, that people value. The malware developers extort ransom and promise to provide a decryption key in return. Full decryption of lost data is possible in a minority of cases, if an offline encryption key was used, otherwise, use instructions on the page to recover enciphered files. The ransomware also creates a ransom note (_readme.txt) that informs the victim about the attack and demands payment in Bitcoin or other cryptocurrencies in exchange for the decryption key.

Such redirection schemes are designed to help cybercriminals generate fake traffic and earn commissioned money on it.
