Conduent Ransomware Attack: Maze Posts Stolen Information
The corporation did not identify the ransomware style or intrusion vector, but the Maze ransomware team has posted stolen Conduent facts including apparent consumer audits to its Dark Web site.
Stability researchers at Lousy Packets say Conduent, which employs sixty seven,000 globally, was working unpatched Citrix VPNs for “at least” 8 weeks. (An arbitrary code execution vulnerability in Citrix VPN appliances, known as CVE-2019-19781, has been greatly exploited in the wild by ransomware gangs.)
In early January Lousy Packets identified practically ten,000 susceptible hosts working the unpatched VPN were recognized in the US and in excess of two,000 in the United kingdom. Citrix pushed out firmware updates on January 24.

They generally sit in a network collecting facts to steal and use to blackmail their victims right before really triggering the malware that locks down finish-details.
The attack follows incredibly hot on the heels of a further effective Maze breach of fellow IT solutions organization Cognizant in April.
Regulation enforcement and protection gurus go on to urge companies to strengthen essential cyber hygiene, from introducing multi-aspect authentication (MFA), to making sure common method patching.
