About BianLian

BianLian is an infamous cybercriminal organization involved in the development and deployment of ransomware. Since June 2022, they have targeted various critical infrastructure sectors in the United States. Additionally, they have extended their attacks to include Australian critical infrastructure sectors, professional services, and property development domains.

The group exploits valid Remote Desktop Protocol (RDP) credentials to gain unauthorized access to their victims' systems. They employ open-source tools and command-line scripts to carry out reconnaissance and gather credentials. Victim data is then extracted using File Transfer Protocol (FTP), Rclone, or Mega. Subsequently, the BianLian group proceeds to extort money from their victims by threatening to expose the obtained data unless a payment is made.

Initially, the group utilized a double-extortion approach, which involved encrypting victims' systems after data exfiltration. However, starting around January 2023, they primarily focused on data exfiltration-based extortion.
