The U.S. has charged a suspected Russian hacker with breaking into computers at LinkedIn, Dropbox and Formspring. The 29-year-old Yevgeniy Aleksandrovich Nikulin was arrested by Czech police in Prague on Oct. 5. LinkedIn and Dropbox were involved in major data breaches in 2012. Nikulin remains in custody in the Czech Republic, but local courts there could choose to extradite him to the United States. He could face up to 32 years in prison.”]
