What is BlackPink ransomware? And how does it implement its attack?
BlackPink ransomware is a file-encrypting virus designed to lock important data in a targeted computer. This newly discovered crypto-malware uses a “.BlackPink” extension in marking the files it encrypts. It seems to be targeting Korean-speaking users as its ransom note is written in the Korean language. At the time of writing, it isn’t clear yet if this new ransomware belongs to any ransomware group.
Once the payload file of BlackPink ransomware is executed, it will start to implement its attack by performing a series of modification in the system. It also establishes a connection to a remote server controlled by cyber crooks behind this crypto-virus. This is where BlackPink ransomware downloads its malicious components which are placed on several system folders allowing BlackPink ransomware to repress or launch system processes. It generates a victim’s ID by collecting data from the infected system using a data gathering module. It also scans the computer for certain programs like firewall, sandbox environments, virtual hosts and antivirus programs that might interfere with the attack and if it finds them, it either removes or disables them.
Moreover, BlackPink also modifies some registry keys and sub-keys in the Windows Registry allowing it to run automatically in every system boot, making it a persistent attack. Once it completes modifying system settings, BlackPink ransomware will start to encrypt its targeted files using AES 256 encryption algorithm. After the encryption, it opens a text file named “how_to_recover_files.txt” which contains the following message:
