To commemorate their 12th anniversary the band released Otras Canciones, a covers album with the Attaque 77 members' favorite songs, signed with Ariola Records.

The 2003 album Antihumano marked the band's biggest mainstream success in Argentina and other countries, led to the alternative rock hit "Arrancacorazones" and melodic hardcore "Ojos de perro" and "Los Buenos Deseos".

In early 2009, Ciro Pertusi left the group for personal reasons, leaving only Martinez, De Cecco and Scaglione as current members.

Pertusi recently formed a new group called "Jauría" in 2010, with Esteban '22' Serniotti on guitar and vocals, Mauro Ambesi on bass and Ray Fajardo (ex-El Otro Yo) on drums.

In March 2015, a documentary movie about the band "Mas de un Millon" was selected to be premiered mid-April at the Buenos Aires International Festival of Independent Cinema.
