A cracked version of Uranium Backup can be modified to include backdoors. This allows hackers to monitor your sensitive data as it is being backed up, effectively giving them a roadmap to your most valuable information.

Crack files are one of the most common delivery methods for ransomware. Instead of getting a free backup tool, you may inadvertently install software that encrypts your files and demands payment to get them back.
