Let’s take a look at a brief overview of data leaks from last week. In the spotlight: TSMC, Parks Victoria, Huobi, Nickelodeon, Anonymous Sudan, Microsoft, Pepsi Bottling Ventures, California retirees, Advanced Medical Management.

TSMC, the globe’s leading semiconductor manufacturer, has verified a data breach after being identified as a victim by the LockBit ransomware group. The cybercriminal gang named TSMC on its leak site in the dark web last Thursday.

A system crash in Parks Victoria’s online booking platform has left users worried about a possible data breach. James Newbury, the shadow minister for environment and climate change, has expressed his support for the shift to a digital system.

The cryptocurrency exchange Huobi has addressed a major data breach, revealing the contact details of nearly 5,000 users. The incident, attributed to inappropriate operations in Huobi’s Japanese AWS testing environment, took place on June 22, 2021. It was first brought to Huobi’s attention by a white-hat hacker in June 2022, but the rectification process was delayed.

The popular American TV channel Nickelodeon has disclosed a data breach that occurred earlier this year. Reports of a significant leak from Nickelodeon’s animation department began surfacing online late last month, with claims on social media that about 500GB of documents and media files were stolen.

Despite hacking group Anonymous Sudan alleging that they are selling data purportedly belonging to Microsoft, the tech giant has vehemently denied any data breach. Microsoft acknowledged last month that service disruptions to its OneDrive web portals, Azure, and Outlook apps were due to Layer 7 DDoS attacks.

A data breach at independent bottling firm Pepsi Bottling Ventures has impacted more than 28,000 people. The breach, discovered on January 10, took place between December 23, 2022, and January 19, 2023, leading to unauthorized access to employees’ personal, financial, and health data.

A group of California State Retirees is suing a vendor over a data breach. The legal action seeks class-action status for Californian residents affected by the data theft, claiming that the companies involved failed to uphold adequate security measures or protect Californian residents’ privacy effectively.

Advanced Medical Management, LLC reported a data breach to the Montana Attorney General that resulted in the leakage of PHI and SSNs. The company found that portions of its IT network, managed by third-party vendors, were open to unauthorized access.
