A hacker who illegally accessed cloud-based accounts of 89 artists — including Ed Sheeran and Lil Uzi Vert — and sold their unreleased music on the dark web in exchange for cryptocurrency was sentenced to 18 months in jail.

Adrian Kwiatkowski of Hampton Road, Ipswich, was found guilty of obtaining unreleased and unfinished material from the said accounts and made £131,000 ($148,000), according to the City of London Police on Friday (October 21).

The 23-year-old hacker pleaded guilty to 14 copyright offenses, three counts of computer misuse and three offences under the Proceeds of Crime Act at the Ipswich Magistrates Court on August 27.

Most recently, he was sentenced to 18 months in jail at Ipswich Crown Court.

The sentence marks the culmination of a yearslong investigation into Kwiatkowski, which began when the management companies of several musicians reported that the hacker, known online as Spirdark, gained access to a series of accounts and sold unreleased music online.

The Manhattan District Attorney’s Office launched the investigation in 2019. The probe managed to track Spirdark’s cryptocurrency account, as well as the IP address of the device used to hack one of the accounts as his home address.

Kwiatkowski was then arrested on September 12, 2019 following further investigation and seven of his devices including a hard drive containing 1,263 unreleased songs by 89 artists were uncovered. About £64,000 worth of Bitcoin was also…
