Taiwanese computer giant Acer has admitted it was hacked after a threat actor put up for sale on a popular hacking forum what they claim is 160GB of data stolen from the manufacturer in mid-February 2023.

The offered dataset allegedly contains confidential slides, staff manuals, confidential product documentation for phones, tablets, and laptops, binary files, information on backend infrastructure, disk images, replacement digital product keys, and BIOS-related information.

As proof of the theft the seller provided screenshots of technical schematics for the Acer V206HQL display, documents, BIOS definitions, and confidential documents.

In a statement to the tech news site BleepingComputer Acer’s spokesperson has confirmed that one of the company’s document servers for repair technicians was compromised. The electronics maker said that the investigation into the incident is still ongoing, but at this time there’s no indication that customer data was affected in the hack.

Acer has suffered several cyberattacks over the past few years, including a $50 million REvil ransomware compromise in March 2021.
