Authorities in Taiwan say they are looking into a ransomware cyber-attack on a major technology firm there.
Quanta Computer is a manufacturer of many flagship Apple products, including its MacBook line.
The hackers, known as Revil, have published stolen blueprints for unreleased products, and are threatening to release more.
Taiwanese officials said they are "taking an initial step to look into and understand" the incident.
It is being handled by the Ministry of Justice's investigation bureau.
On their darknet website, the anonymous hackers are attempting to extort a ransom from Apple directly, writing: "We recommended that Apple buy back available data by 1 May."
It is understood they are asking for tens of millions of pounds.
How close the alleged blueprints will be to any actual future products is not clear. Bloomberg reports that the leaked materials include the schematics for a future MacBook laptop. The Guardian reports that a new Apple Watch is also among them.

Apple has not responded, but Quanta confirmed a cyber-attack had taken place.
In a press release, the company said: "Quanta Computer's information security team has worked with external IT experts in response to cyber-attacks on a small number of Quanta servers.
"We've reported to, and kept seamless communications with, the relevant law enforcement and data protection authorities concerning recent abnormal activities observed. There's no material impact on the company's business operation."
