2021-006: ASD's ACSC Ransomware Profile - Lockbit 2.0 Advisory
Aug 5, 2021 - The LockBit ransomware restricts access to corporate files and systems by encrypting them into a locked and unusable format. Victims receive instructions on how to engage with the offenders after encryption. LockBit affiliates have successfully deployed ransomware on corporate systems in a variety of countries and sectors, including Australia, where the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) is aware of numerous incidents since 2020. LockBit affiliates are known to implement the ‘double extortion’ technique by uploading stolen and sensitive victim information to their dark web site ‘LockBit 2.0’, and threatening to sell and/or release this information if their ransom demands are not met.
