EP01: We used ChatGPT to Create Ransomware


Hornetsecurity VM Backup

Immutability refers to the quality of being unchanging or unable to be modified. In the context of data backups, immutable backups are copies of data that cannot be altered or deleted by anyone, including the individuals who created them. This feature makes them highly resistant to manipulation or tampering.

Now, why do ransomware gangs harbor such disdain for immutable backups? The answer lies in their malicious intent and the disruptive nature of ransomware attacks. Ransomware is malicious software that infiltrates computer systems and encrypts valuable data, holding it hostage until a ransom is paid. It thrives on the ability to control and manipulate data, leaving victims with few options.

Immutable backups, however, pose a significant obstacle to these cyber criminals. By preserving data in a state that cannot be changed, even by the most sophisticated ransomware, immutable backups provide a failsafe against data loss. When a system is compromised, organizations can restore their data from these secure, unalterable backups, rendering the ransomware attack futile.

We strongly advise utilizing Hornetsecurity’s VM backup service, especially now with the introduction of the V9 feature. Employing VM Backup V9 significantly enhances data security, effectively shielding your data from deletion and unauthorized alterations.
