LOGAN SQUARE — A web site by a company that books musical acts into some area venues was hacked by a pair of Brazian groups, causing potential problems for music fans seeking concert information.

MPShows was taken over by Brazilian hackers who call themselves TheCrashers and LulzBrazil.

An image of a blinking jester in a black field has replaced the MPShows site and when parts of the image are clicked, the user is directed to two Twitter accounts — @TeamCrashers and @TeamP0isoN.

"You can have peace. Or you can have freedom. You won't find both in the same place," reads @TeamP0isoN's profile as translated from Portuguese.

@TeamCrashers' mission seems more straightforward. Its profile, translated from Portuguese, describes it as "a group formed to demonstrate that servers in Brazil are very vulnerable."

It is unclear why they chose to hack the MPShows site, which gives a comprehensive listing of all the firm's concerts.

MPShows books Logan Square musical acts at Township and Ultra Lounge but the Township Tumblr page and the Ultra Lounge website were unaffected.

An MPShows representative declined comment Monday morning.
