After they were leaked online in June 2019, Radiohead released them through the music sharing site Bandcamp for 18 days, with all proceeds going to the environmentalist group Extinction Rebellion. The compilation received positive reviews. Though critics said that its size made it daunting for some listeners, they praised the insight into the making of OK Computer. Content MiniDiscs [Hacked] contains more than 16 hours of demos, rehearsals, outtakes, and live performances recorded while Radiohead were working on their third album, OK Computer (1997).

The recordings are taken from MiniDiscs belonging to the Radiohead singer, Thom Yorke. Though some had been released on the 2017 OK Computer reissue OKNOTOK 1997 2017, most were not intended for release. Release On 5 June 2019, the recordings were leaked online by a collector using the name Zimbra, who claimed to have traded them for unreleased Beatles recordings. They may have been stolen while archived material was being prepared for the OK Computer reissue. The guitarist Ed O'Brien said they had been hacked from Radiohead's cloud archive. According to conflicting reports, Zimbra initially demanded a $150,000 ransom from Radiohead not to release the recordings. However, according to an investigation by Pitchfork, Zimbra had instead hoped to sell them to fans. Zimbra told Pitchfork that "the whole $150k thing and 'ransom' was taken way out of context". A fan who negotiated with Zimbra said he did not believe extortion was his intent: "He never told us anything to suggest he was trying to get money from the band, only from fans." Zimbra released the recordings free after news broke on the discussion site Reddit. On 11 June, Radiohead made the recordings available to stream or purchase from the music distribution site Bandcamp for 18 days. All proceeds went to the environmentalist group Extinction Rebellion, raising approximately £500,000.
