Bassist Tim Commerford hinted that the metal band could be recording a new album.
When asked if the group have anything new in the works, Commerford told TMZ: "Maybe... maybe."
Rage Against the Machine have not released a new album since they disbanded in 2000.
Following Zack de la Rocha's departure in 2000, the rest of the band formed Audioslave with Soundgarden's Chris Cornell until 2007.
The band have since reformed for several gigs and festivals around the world, including the Coachella Valley Music and Arts Festival in 2007.
They also celebrated their unexpected Christmas number one victory in 2009 with a free gig in Finsbury Park the following year.
