Protection researchers at Negative Packets say Conduent, which employs 67,000 globally, was jogging unpatched Citrix VPNs for “at least” eight weeks. (An arbitrary code execution vulnerability in Citrix VPN appliances, recognized as CVE-2019-19781, has been commonly exploited in the wild by ransomware gangs.)
In early January Negative Packets observed practically ten,000 vulnerable hosts jogging the unpatched VPN were being recognized in the US and about two,000 in the Uk. Citrix pushed out firmware updates on January 24.

They usually sit in a network accumulating data to steal and use to blackmail their victims right before really triggering the malware that locks down close-details.
The assault follows very hot on the heels of a different effective Maze breach of fellow IT products and services company Cognizant in April.
Regulation enforcement and stability specialists go on to urge corporations to increase primary cyber hygiene, from introducing multi-variable authentication (MFA), to making certain frequent procedure patching.
