How to remove PixBankBot malware (Android)

0
PixBankBot is an Android banking Trojan that specifically targets Brazilian banks and takes advantage of the Pix instant payment platform. This malicious software utilizes an Automated Transfer System (ATS) framework to carry out its operations. It is crucial to remove PixBankBot from infected devices promptly to prevent potential harm. One of the methods employed by PixBankBot involves utilizing the Accessibility Service to detect and monitor User Interface (UI) components within specific banking applications. By leveraging this service, PixBankBot gains the ability to execute fraudulent transactions on the victim's device through the implementation of ATS functionality. Furthermore, PixBankBot exploits the Accessibility service to conduct keylogging operations. It records the user's interactions with UI elements, capturing sensitive information such as account balances, money transfer details, and the targeted bank. When the victim interacts with certain applications like Banco Itaú, C6 Bank, Mercado Pago, Nubank, PicPay, or PagBank Banco (and potentially other targeted apps), PixBankBot triggers keylogging and activates the ATS. It is important to note that the list of targeted apps may expand over time.

Neqp is a ransomware infection belonging to the Djvu/STOP Ransomware family, that appeared in June 2023. This family has released a number of file encryptors that target various users worldwide. Once the system is penetrated by ransomware, the virus begins scouting for potentially valuable file formats and running data encryption. After the cryptographic encryption occurs, users will no longer be able to access and use their data as before. You may immediately spot the change by looking at the altered names of the files. This specific ransomware assigns the .neqp extension, making a file like 1.pdf change to 1.pdf.neqp and reset its original icon. Usually, Neqp Ransomware and other modern Djvu/STOP versions generate "online" keys, which means full decryption of data is likely impossible without the help of cybercriminals.

How to remove Nerz Ransomware and decrypt .nerz files

0
Just like many previous versions of this virus, Nerz Ransomware is a malicious program recently developed by the STOP (Djvu) ransomware family, which runs data encryption. Once it gets on your computer, the virus covers all personal data with strong encryption algorithms, so that you could no longer be able to get access to them. Unfortunately, preventing ransomware from blocking your data is impossible unless you have special anti-malware software installed on your PC. In case of its absence, the files stored on your disks will be restricted and no longer accessible. After the encryption process is done, you will see all the files change to 1.pdf.nerz and similarly with other file names. This version of STOP ransomware uses .nerz extension to highlight the encrypted data. Then, as soon as ransomware has stormed through your system and put all the sensitive data under a lock, it goes further creating a ransom note (_readme.txt).

How to remove Hidden Ransomware and decrypt .hidden files

0
Hidden Ransomware, a variant of the Voidcrypt ransomware family, is a malicious program that carries out its nefarious activities by encrypting data and then demanding ransoms in exchange for decryption tools.

The new filenames include the original file name, the email address of the cyber criminals, a unique ID assigned to the victims, and the .hidden extension. For example, a file named 1.pdf would be transformed into something like 1.pdf.[Wannadecryption@gmail.com][random-sequence].Hidden after encryption. In addition to the file renaming, the ransomware drops ransom messages in !INFO.HTA files within compromised folders.
