Taiwan Semiconductor Manufacturer Hit by Lockbit Ransomware Gang

February 28, 2024


One of Taiwan's biggest semiconductor manufacturers has fallen victim to a cyberattack, supposedly carried out by the notorious LockBit ransomware gang. The hackers posted a threatening message on Foxsemicon’s website, stating that they had stolen its customers' personal data and would publish it on their darknet website if the company refused to pay. The company’s website, however, could not be accessed as of Wednesday afternoon Eastern U.S. time, while Google search results still display the hackers’ message

The tactic used in the attack on Foxsemicon is atypical for LockBit: Usually, they post the names of the victims on their extortion website rather than deface the company’s web page.
