Multinational tech firm ABB hit by Black Basta ransomware attack
Swiss multinational company ABB, a leading electrification and automation technology provider, has suffered a Black Basta ransomware attack, reportedly impacting business operations.
Headquartered in Zurich, Switzerland, ABB employs approximately 105,000 employees and has $29.4 billion in revenue for 2022. As part of its services, the company develops industrial control systems (ICS) and SCADA systems for manufacturing and energy suppliers.
The company works with a wide range of customers and local governments, including Volvo, Hitachi, DS Smith, the City of Nashville, and the City of Zaragoza.
“ABB operates more than 40 U.S.-based engineering, manufacturing, research and service facilities with a proven track record serving a diversity of federal agencies including the Department of Defense, such as U.S. Army Corps of Engineers, and Federal Civilian agencies such as the Departments of Interior, Transportation, Energy, United States Coast Guard, as well as the U.S. Postal Service,” reads the ABB web site.
On May 7th, the company fell victim to a cyber attack conducted by the Black Basta ransomware gang, a cybercrime group that surfaced in April 2022.
BleepingComputer has learned from multiple employees that the ransomware attack has affected the company’s Windows Active Directory, affecting hundreds of devices.
In response to the attack, ABB terminated VPN connections with its customers to prevent the spread of the ransomware to other networks.
BleepingComputer independently confirmed the attack from a source familiar with the situation and who asked to remain anonymous.
The attack reportedly disrupts the company’s operations, delaying projects and impacting the factories.
After first declining to comment on the cyber attack, ABB sent us the following statement after the publishing of this article.
“ABB recently detected an IT security incident that directly affected certain locations and systems,” says a statement to BleepingComputer.
“To address the situation, ABB has taken, and continues to take, measures to contain the incident. Such containment measures have resulted in some disruptions to its operations which the company is addressing. The vast majority of its systems and factories are now up and running and ABB continues to serve its customers in a secure manner.:
“ABB continues to work diligently with its customers and partners to resolve this situation and minimize its impact.”
Who is Black Basta?
The Black Basta ransomware gang launched its Ransomware-as-a-Service (RaaS) operation in April 2022 and quickly began amassing corporate victims in double-extortion attacks.
By June 2022, Black Basta had partnered with the QBot malware operation (QakBot), which dropped Cobalt Strike on infected devices. Black Basta would then use Cobalt Strike to gain initial access to the corporate network and spread laterally to other devices.
Like other enterprise-targeting ransomware operations, Black Basta created a Linux encryptor to target VMware ESXi virtual machines running on Linux servers.
Researchers have also linked the ransomware gang to the FIN7 hacking group, a financially motivated cybercrime gang also known as Carbanak.
Since its launch, the threat actors have been responsible for a stream of attacks, including those on the American Dental Association, Sobeys, Knauf, and Yellow Pages Canada.
Recently, the ransomware operation attacked Capita, the UK’s largest outsourcing company, and began to leak stolen data.
