Varian, a subsidiary of Siemens Healthineeres, provides software for the oncology department's applications and specializes in offering therapeutic and diagnostic oncology services. The California-based corporation has more than 10,000 employees as of 2021 and had an annual profit of £269 million.
While it is still unclear how LockBit got access to Varian's systems or how much data was stolen, the ransomware gang warned readers of its "victim blog" that if the company did not meet their demands within two weeks, soon, its private databases and patient medical data would be made public. Apparently, Varian has until 17 August to meet the negotiation demands in order to restore their stolen data, if they wish to avoid ‘all databases and patient data’ from being exposed in LockBit’s blog.
The attack is most likely to be a part of ‘triple extortion,’ a strategy usually used by ransomware actors. The strategy involves a three-part attack on an organization that starts with the theft of data that appears to be sensitive before it is encrypted. The corporate victim of the breach can only get their data back and keep it private if they pay a ransom, following which they will receive – in theory – a decryption key from the hackers.
In regards to the breach, Siemens Healthineers – Varian’s parent company confirmed that an internal investigation is ongoing. However, they did not provide any further details of the breach.
“Siemens Healthineers is aware that a segment of our business is allegedly affected by the Lockbit ransomware group[…]Cybersecurity is of utmost importance to Siemens Healthineers, and we are making every effort to continually improve our security and data privacy,” said a spokesperson.
Growing Cases of LockBit
Recent months have witnessed a good many cyberattacks conducted by LockBit against some major companies. According to a report by the US Cybersecurity and Infrastructure Security Agency, in the first quarter of 2023, the ransomware gang has already targeted 1,653 companies. They frequently repurposed freeware and open-source tools for use in network reconnaissance, remote access, tunnelling, credential dumping, and file exfiltration.
Some examples of the LockBit hit companies would be their recent campaign against the port of Nagoya, which ossified supply chains for Japanese automobile company Toyota, and SpaceX in which the ransomware gang claims to have led to a haul of 3,000 proprietary schematics, and an attempt to extort $70 million from Taiwanese chip maker TSMC.
