Lockbit Demands $70M of TSMC Chipmaking Giant

July 3, 2023


Chipmaking giant TSMC denied being hacked after the LockBit ransomware gang demanded $70 million not to release stolen data.

On Wednesday, a threat actor known as Bassterlord, who is affiliated with LockBit, began to live tweet what appeared to be a ransomware attack on TSMC, sharing screenshots with information related to the company. While this Twitter thread has since been deleted, the LockBit ransomware gang created a new entry for TSMC yesterday on their data leak site, demanding $70 million or they would leak stolen data, including credentials for their systems.

A TSMC spokesperson told BleepingComputer that they were not breached, but rather the systems of one of their IT hardware suppliers, Kinmax Technology, were hacked. "Upon review, this incident has not affected TSMC's business operations, nor did it compromise any TSMC's customer information."

Apart from validating that its systems had not been impacted in any way, TSMC states that it also stopped working with the breached supplier until the situation cleared up.
