BianLian ransomware gang has been noted by a joint advisory from the FBI, Cybersecurity and Infrastructure Security Agency, and Australia's Cyber Security Centre to have changed up its operations to leverage exfiltration-based extortion rather than ransomware encryption it initially used since its emergence two years ago, SiliconAngle reports.
Various critical infrastructure entities and other organizations in the U.S., UK, and Australia have been compromised by BianLian last year through the use of valid Remote Desktop Protocol credentials and open-source tools, which facilitated data exfiltration efforts.
Organizations have been urged by the joint advisory to adopt security measures to better protect themselves from the threat of BianLian ransomware, including the implementation of remote access tool audits and remote access detection software.
Meanwhile, Halcyon Tech CEO Jon Miller noted that BianLian's transition indicates the high level of success for double extortion.
"It works so well that we will likely see more groups follow suit and forego the hassle of developing and managing the encryption and decryption process in favor of a less complicated attack," Miller added.
SiliconAngle reports that ransomware attacks against the educational sector have significantly increased from 2018 to 2022 and are expected to reach a record high this year, with 85 attacks recorded during the first half of 2023 being almost two times higher than the same period in 2022.
Air Canada has confirmed being impacted by a data breach that compromised some of its employees' limited personal data and other records, reports The Record, a news site by cybersecurity firm Recorded Future.
