What is Basilisque ransomware? And how does it carry out its attack?
Basilisque ransomware is a file-encrypting malware designed to lock important data in a targeted computer. It uses random strings and a “[email protected]_com” extension in marking the files it encodes. This new threat is the same as other typical ransomware infection which means that it carries out its attack in the usual way other ransomware threats does.
Once it carry out its attack, Basilisque ransomware will drop its malicious payload in the system. Upon the execution of the payload file, Basilisque ransomware will connect the infected computer to a remote server controlled by the attackers. After establishing connection, it makes modifications in the Windows Registry so that it can run on every system boot. It also downloads additional malicious files in the system folders. These files along with the data gathered about the system and the user are then used for stealth protection which allows the crypto-malware to execute its attack without any interruption from any security programs.
After the system modifications, Basilisque ransomware, will start encrypting its targeted files using the AES 128 encryption algorithm. Following data encryption, it adds .Basilisque suffix to each one of the encrypted files and releases its ransom note, HOW_TO_DECRYPT.txt, which contains a quite lengthy message. Here are some parts of its ransom note:
“What happened to your files ?
