AC/DC's forthcoming new album, "Black Ice", leaked onto file sharing service BitTorrent on October 7 and has been downloaded over 400,000 times.
The album, set for official release on Monday (October 20), will not be available as a legal download.
According to Undercover the band's label, Sony, released fake AC/DC songs online to hamper users attempting to download the album.
However, Torrentfreak claimed that there was no evidence of the fake tracks online.
AC/DC boycott Apple's iTunes download service as well as other similar services, but still enjoy huge sales of their albums. In 2007 they sold 1.3 million albums in the USA.
AC/DC's Angus Young has said that the band's decision to refrain from releasing music digitally was motivated by a desire to ensure their fans enjoy their albums as wholes, not simply a few tracks at a time.
"We don't make singles, we make albums," he told the Telegraph. "We believe the songs on any of our albums belong together."
