Haker ili iskušavanje đavola is the second album by the Serbian noise-rock band Klopka Za Pionira, released in 2004 (see 2004 in music) on the Ne-ton independent label.

Also, there is no guitar and no vocal input from Mileta Mijatović, the band's singer.

The whole album consists of various machine buzzes and computer generated noises accompanied by a large amount of sampled voices originating from English translations of speeches by Josip Broz Tito, operas in Serbian, children's educational records, Orthodox chanting, the opening speech from a concert entitled "Trumpets of Peace" held in Sarajevo 1977, "The Internationale" sung in Serbian, various commercials, old Yugoslav movies, SpongeBob SquarePants dubbed in Serbian, etc.

Hacker was chosen as album's name because of the heavy use of sampling and lack of non-computer generated sounds, while "tempting the devil" alludes to many religious samples often juxtaposed to give a meaning completely different from the original.

On its official website, the band stated that the album deals with "the clash of past ideologies with present times through unusual combination of samples on the theme of totalitarianism and religion.
