US-based business travel company CWT said last week that it paid cyber criminals $4.5 million as ransomware.
The attackers initially demanded $10 million, claiming that 30,000 CWT computers were infected, and 2 terabytes of files were encrypted. In reality, the number of the infected computers was smaller.
