The hacker group Lulz Security has opened a telephone request line so its fans can suggest potential targets.
It claims to have launched denial of service attacks on several websites as a result, although it did not detail which ones.
The unspecified hacks formed part of a wave of security breaches that the group called Titanic Takeover Tuesday.
LulzSec has risen to prominence in recent months by attacking Sony, Nintendo and several US broadcasters.
The group publicised the telephone hotline on its Twitter feed.
