New ShrinkLocker ransomware uses BitLocker to encrypt your files

ShrinkLocker is a VBScript ransomware that abuses native Windows features—shrinking non-boot partitions to create new boot volumes, reinstalling boot files with BCDEdit, and enabling BitLocker while deleting recovery protectors—to lock systems and deny recovery; it has been observed against a government entity and organizations in the steel and vaccine manufacturing sectors across multiple countries, uses contact emails embedded as boot volume labels instead of a visible ransom note, and leverages legitimate services (TryCloudflare) to exfiltrate encryption keys.
