The business did not identify the ransomware type or intrusion vector, but the Maze ransomware team has posted stolen Conduent details including apparent shopper audits to its Darkish World wide web website page.
Safety researchers at Poor Packets say Conduent, which employs sixty seven,000 globally, was running unpatched Citrix VPNs for “at least” 8 months. (An arbitrary code execution vulnerability in Citrix VPN appliances, acknowledged as CVE-2019-19781, has been widely exploited in the wild by ransomware gangs.)
In early January Poor Packets observed practically 10,000 susceptible hosts running the unpatched VPN had been determined in the US and about 2,000 in the United kingdom. Citrix pushed out firmware updates on January 24.
