- CryPy Ransomware Encrypts Each File Individually with a Special Key
New Ransomware CryPy Can Encrypt Each File Individually with a Special Key — The C&C of this ransomware is hosted on a hacked Israeli server. This ransomware has been written in Python. CryPy stands out is that it encrypts files on a system individually and that too, with a unique key for every file. This obviously makes data decryption very difficult. The team identified that CryPy has two main files namely boot_common.py and encryptor.py. The first one error logs on Windows OS and the second one is the main locker. After the computer has been infected the Registry Tools are the first to be disabled by CryPy and then the focus is shifted to Task Manager, Run and CMD. Afterwards, boot status policy and recovery tools are disabled. When the disabling function has been performed successfully, the malware begins encrypting the files using a different encryption key for each file.
Cyber Security Tips: To prevent from ransomware attack keep backup of your data, use updated antivirus, avoid to use malicious websites, and avoid to click on spam mails.
