How to remove Bitenc Ransomware and decrypt .bitenc files

0
Bitenc is a new file encryptor originating from the Mallox ransomware family. Malware of this type is designed to encrypt victims' files and demand payment in exchange for the decryption key. Once Bitenc Ransomware infects a system, it will scan the system for potentially important file types (e.g., documents, images, videos, etc.) and write secure ciphers over the targeted data. In addition, the virus also appends its custom .bitenc extension. For instance, a file originally named 1.pdf will change to 1.pdf.bitenc and become no longer accessible. The appendance of new extensions is usually done to simply highlight the blocked data and make victims spot the effects of encryption. Following successful encryption, developers behind Bitenc Ransomware present their ransom demands within the FILE RECOVERY.txt text note which is created on the victim's desktop.

How to fix “System UI isn’t responding” error in Android

0
System UI not responding, "System UI isn't responding", "Unfortunately, System UI has stopped", and other similar UI-related error messages can unexpectedly appear on your Android device and prevent further interaction with it. UI stands for User Interface, and it is everything that involves interaction with device apps, features, content, and various functions. The issue when System UI stopped responding often appears in a pop-up window and prevents users from further display usage. As a result, your device will likely attempt to restart the System UI app itself in order to get your phone back to working properly. Unfortunately, while for some users this error appears only once due to a rare system glitch and does not come back, in other cases it may ring its presence again and interrupt users' experience continuously. This problem is regularly defined to be caused by corrupted cache or temporary files, lack of device memory, uninstalled updates, and even problematic third-party apps that create incompatibility issues. You can follow our guide with 5 potential solutions that will fix the "System UI isn't responding" error. Please note that the steps outlined in our instructions can look slightly different depending on your Android device.

How to remove Buddyransome Ransomware and decrypt .buddyransome files

0
Buddyransome is a ransomware virus that functions by encrypting access to data. Cybercriminals use its capabilities to restrict potentially important files and blackmail victims into paying money for full decryption. Victims can see the malicious change once targeted files get altered with the new .buddyransome extension – for instance, a file like 1.pdf will change to 1.pdf.buddyransome and reset its original icon after successful encryption. After this, a text note containing decryption instructions (HOW_TO_RECOVERY_FILES.txt) will be created. Victims are said all the significant data has been encrypted and is now at risk of being published to online resources. To prevent this and decrypt the blocked data, cybercriminals instruct to write an e-mail message to buddyransome@aol.com and include their personal ID by copy-pasting it from the generated note. After this, threat actors should respond with the price for decryption/non-disclosure of data and provide instructions on how to perform the payment.

How to remove DeathOfShadow Ransomware and decrypt .Death_Of_Shadow files

0
DeathOfShadow is a ransomware virus that encodes access to system-stored files (using AES+RSA algorithms) and demands victims to pay money for decryption. During encryption, it also assigns its own .Death_Of_Shadow extension to highlight the blocked data. For instance, a file like 1.pdf will change to 1.pdf.Death_Of_Shadow and become inaccessible. After all targeted files end up restricted, the virus creates a text note called (Malakot@protonmail.com).txt or (malakot@tutanota.com).txt depending on what ransomware version attacked the system. The text note is where cybercriminals outline decryption instructions for their victims. Overall, it is said victims have to contact extortionists through their e-mail address. Following this, victims will supposedly be given further guidelines on how to pay money and return the files. As a rule, most cybercriminals make demands to pay ransoms in crypto as it is an untraceable and safe way to receive fraudulent earnings. In addition, threat actors offer to test their decryption abilities implying that victims can send a file (non-valuable and up to 10 MB) and get it decrypted for free. The text in the ransom note also warns that unless victims establish contact with cybercriminals within 48 hours, the decryption of files will no longer be possible.

How to remove Mzqw Ransomware and decrypt .mzqw files

0
Mzqw Ransomware (aliases: Djvu Ransomware, STOP Ransomware) is an extremely dangerous file-encrypting virus, that extorts money in exchange for decrypter. Ransomware utilizes a strong AES-256 encryption algorithm and makes files unusable without decryption master key. Particular malware in this review appeared in the end of January 2023 and appends .mzqw extensions to files. As a result, file example.jpg converts to example.jpg.mzqw. Mzqw Ransomware creates a special text file, that is called _readme.txt, where hackers give contact details, overall information about encryption, and options for decryption.

How to remove SecureAgent Ransomware and decrypt .secured files

0
SecureAgent is a ransomware virus that encrypts system-stored data and blackmails victims into paying money for its decryption. Along with encrypting access to data, the ransomware also assigns the .secured extension to highlight the blocked files. For instance, a file originally named 1.pdf will change to 1.pdf.secured and reset its icon as well. After encryption is done, the virus changes the desktop wallpapers and displays a pop-up window containing decryption guidelines. Overall, the window features a deadline timer for transferring $120 (in Bitcoin) to the cybercriminals' crypto address. After the given time expires, the decryption key for unlocking the data will supposedly be deleted making files permanently inaccessible. Developers behind SecureAgent do not provide any contact information, which makes it unclear how they will send a decryption key after the payment.
