The Bialian Ransomware Gang's Attack on Bunn-O-Matic

The Bialian ransomware gang has attacked Bunn. Bunn-O-Matic is a dispensed beverage equipment manufacturer headquartered in Springfield, Illinois. It was founded in 1957 and offers its products to both commercial and trade customers. Bianlian posted Bunn-O-Matic to its data leak site on July 9th but did not specify the ransom, deadline, or allegedly stolen data. Bunn-O-Matic has neither confirmed nor denied the attack.

Who is 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.

How Does BianLian Operate?

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.

Evolution of BianLian's Tactics

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.
