Russian hackers have stolen 1.2 billion user names and passwords in a series of Internet heists affecting 420,000 websites, according to a report.
The thievery was described in a New York Times story based on the findings of Hold Security, a Milwaukee firm that has a history of uncovering online security breaches.
The identities of the websites that were broken into were not identified by the newspaper, which cited non-disclosure agreements that required Hold Security to keep some information confidential.
The reported break-ins are the latest incidents to raise doubts about the security measures that both big and small companies use to protect people’s information online. Security experts believe hackers will continue breaking into computer networks unless companies become more vigilant.
