(Undated) -- An anonymous hacker claims to be part of a team responsible for publishing nude photos of more than 100 celebrities. In claims posted to a known hacker comment board, the anonymous user says the security breach took months to pull off. The alleged hacker also says more than one person was involved in breaking into iCloud files of celebrities. The compromised files include those of Academy Award winner Jennifer Lawrence. The poster also said he or she was moving to another area, more than likely to avoid being caught. The FBI is investigating and Apple says it's patched up the security flaw that allowed the break-in.
