Why do companies pay ransoms to ransomware creators after their drives are encrypted, despite having full backups?

In the article on KrebsonSecurity, the author discusses the increasing number of ransomware attacks that force victims to pay a ransom in exchange for regaining access to encrypted data. However, some criminal groups are introducing enticing changes to this scheme—rather than completely locking users out of their data, they test victims' backups. The intent is to push users to invest in better security measures and eliminate weaknesses in their backup procedures. The author points out that this phenomenon might catch many businesses and private individuals off guard, as they may not be fully prepared for the consequences of cyberattacks. Therefore, it is crucial for anyone storing sensitive data to regularly check and update their backup systems, as well as implement appropriate security measures. The article concludes with a call for caution and proactive action in the face of evolving threats from cybercriminals.
