FBI: Christina Aguilera, Scarlett Johansson, Mila Kunis, victims of "celebrity hacker"

Chaney hacked Google, Apple and Yahoo email accounts beginning last November and December, then hijacked the forwarding feature so that a copy of every email received was sent, "virtually instantaneously," to an email account he controlled, according to an indictment handed up Tuesday by a federal grand jury in Los Angeles. 

There were more than 50 victims, including actress Renee Olstead, according to the indictment.

Chaney offered some material, including photographs, to celebrity blog sites and some of the files and photographs ultimately were posted, according to an FBI statement.

Chaney allegedly used the hacker names "trainreqsuckswhat," "anonygrrl" and "jaxjaguars911." He is charged with 26 counts of identity theft, unauthorized access to a protected computer and wiretapping.

If convicted, he faces up to 121 years in prison.

The FBI announced wednesday that it had made an out-of-state arrest in a year-long investigation of celebrity hacking that was dubbed Operation Hackerazzi.

Nude shots of Johansson appeared on an Internet site earlier this year and TMZ.com reported that hackers stole them from her cellphone.
