A new bootlocker ransomware was discovered by Malware Blocker called RedBoot. When executed it will encrypt files on the computer, replace the MBR, or Master Boot Record, of the system drive and then modifies the partition table in some manner. As the ransomware does not provide a way to input a key to restore the MBB and partition table, unless the ransomware developer has a bootable decryptor this malware may be a wiper. The developer of RedBoot contacted BleepingComputer and a new version of the malware will be released in October.
