Ransomware groups are cybercriminal organizations specialized in deploying malware that encrypts victims’ data, making this information inaccessible. Once the data has been encrypted, these groups typically demand a ransom, often paid in cryptocurrency, in exchange for the decryption key enabling victims to recover their data. These attacks can target individuals, businesses, government institutions or critical infrastructures, causing major disruption and considerable financial loss.
Over the years, several ransomware groups have emerged and gained notoriety for their large-scale attacks and exorbitant ransom demands. These groups use sophisticated techniques, exploit vulnerabilities and constantly adapt their methods to evade detection and maximize their profits. In addition to encrypting data, some also threaten to divulge sensitive information if they don’t receive payment, adding an extra dimension of blackmail to their operations.
