1 billion more Yahoo accounts have been hacked

An article in USA Today about third-party forensic evidence that has led Yahoo to believe that someone stole user data from 1 billion Yahoo accounts in 2013 quotes Arun Vishwanath, associate professor of communication, who said the fact that the breach went unnoticed for so long isn’t surprising. “The sobering facts are that almost all such hacks are only accidentally discovered and that hackers usually stay in the system undetected for at least a year if not more," he said. "Yahoo's case is not so unique. Only its scale is troubling.” The article appeared in news outlets around the nation, including WUSA-TV in Washington, D.C., and KHOU-TV in Houston, as well as on MSN outlets in New Zealand, United Arab Emirates, Singapore and Philippines, and in Guam’s Pacific Daily News.

He also was quoted in an article on Buzzfeed, noting that since many people use one password for multiple accounts, the Yahoo hackers are likely attempting to breach other accounts across the internet. “The most likely thing hackers have done is harness the passwords to affect targeted attacks or for conducting widespread DDoS-type attacks using the known password combinations, as we saw with the recent Dyn attack,” he said.
