What is CSP ransomware? And how does it implement its attack?

CSP ransomware is a new crypto-virus that can lock important files in an infected machine. This new crypto-virus uses a “_csp” extension in marking its encrypted files. It supposedly gives its victims 48 hours to pay for the decryption key used to recover the encrypted files. The instant it invades a targeted computer, it will launch its attack by connecting the system to a remote Command and Control server. This remote server is controlled by the creators of CSP ransomware.

CSP Ransomware

After its infiltration, CSP ransomware will start a quick system scan to check if the system is already encrypted or not.  Once it determines that the system hasn’t been encrypted yet, it will download its malicious components and puts them into several folders. These components are used to either launch or repress system processes, thus, allowing the crypto-malware to manipulate various processes.

CSP ransomware also utilizes an information-gathering module used to obtain data from the infected computer and use them for the stealth protection module. This second module is used to scan the system for strings of programs like Firewall, virtual hosts, a sandbox environment, and antivirus programs. Once it finds these programs, it either disables them or completely removes them from the computer to prevent them from interrupting the attack.

In addition, CSP ransomware also alters some registry keys so that it can run automatically in every system boot, making it a persistent attack and even harder to remove. Following all the system modifications, it starts to encrypt files with specific formats using the AES encryption algorithm. After the encryption, it adds the “_csp” extension to every affected file and opens a text file named “HOW TO DECRYPT[1T0t0].txt” which contains the following message:
