Third teenager charged with second-degree murder | SaltWire #newsupdate #news #halifax #policeSAN FRANCISCO - Hackers broke into UnitedHealth's tech unit on Feb. 12 by exploiting a security vulnerability in software from private IT company Citrix that allows employees remote access to their desktop computers, the largest U.S. health insurer will testify before a House panel this week.
"Not knowing the entry point of the attack at the time, we immediately severed connectivity with Change’s data centers to eliminate the potential for further infection," the testimony says. A Citrix spokesman didn't immediately respond to a request for comment. It's unclear which specific security flaw at Citrix was exploited by AlphV, but U.S. officials issued multiple warnings about security loopholes in Citrix tools late last year, some of which were being used to breach healthcare groups.
UnitedHealth has been working with the FBI and prominent cybersecurity firms to investigate the hack. Security experts from Google , Microsoft , Cisco and Amazon worked with teams from Mandiant and Palo Alto Networks to secure Change Healthcare's systems after the breach, according to the testimony.
