Threat Database Ransomware Nyx Ransomware

Nyx Ransomware

Nyx is a ransomware that encrypts files and appends the victim's ID, an email address ('' or ''), and the '.NYX' extension to filenames. The Nyx Ransomware also drops a 'READ_ME.txt' file containing its ransom note. The ransom note instructs victims to contact threat actors via email with their provided ID if they want to restore their files. Victims can send up to three files for free decryption before paying for data decryption.

The ransom note also warns victims not to try recovering their files using any third-party software, as it may permanently damage the data. The attackers threaten that files will be leaked on various forums if victims refuse to contact them, revealing that they are using double-extortion tactics as part of the threatening operation. The Nyx Ransomware is particularly threatening because it uses strong encryption algorithms, which makes it difficult for victims to recover their data without reaching out to the cybercriminals.

The Nyx Ransomware Exerts Additional Pressure on Victims

Double extortion tactics, such as the ones employed by the threat actors behind Nyx Ransomware, are becoming a common feature of ransomware attacks. This involves the threat actors not only encrypting the victims' data but also exfiltrating sensitive information and threatening to leak it publicly if the impacted organizations or users do not pay the ransom. This creates an additional incentive for victims to pay up, as they risk having their confidential data exposed if they do not comply with the attackers' demands. Double extortion tactics are particularly effective because they increase the pressure on victims to pay up quickly and can be used in combination with other techniques, such as social engineering or phishing attacks.
