ShrinkLocker is a recent ransomware strain that leverages a legitimate Windows encryption feature, BitLocker, to lock victims out of their devices. It shrinks the partition, increasing the impact of the attack. 

Casio now confirms it suffered a ransomware attack earlier this month, warning that the personal and confidential data of employees, job candidates, and some customers was also stolen.
