Title: CISA and Partners Release Update to BianLian Ransomware Cybersecurity Advisory
Feedly Summary: Today, CISA, the Federal Bureau of Investigation (FBI), and the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) released updates to #StopRansomware: BianLian Ransomware Group on observed tactics, techniques, and procedures (TTPs) and indicators of compromise attributed to data extortion group, BianLian.
The advisory, originally published May 2023, has been updated with additional TTPs obtained through FBI and ASD’s ACSC investigations and industry threat intelligence as of June 2024.
