(Undated) -- A security expert says the breach of information on four and-a-half million hospital patients is the first known large-scale use of the "Heartbleed" Internet bug. David Kennedy of TrustedSec said today that hackers who broke into Community Health Systems' computer system used stolen credentials and posed as employees to log into the network. Kennedy says hackers then stole millions of Social Security numbers and other records. Community Health Systems said earlier this week that the attack originated in China.
