(An arbitrary code execution vulnerability in Citrix VPN appliances, regarded as CVE-2019-19781, has been commonly exploited in the wild by ransomware gangs.)
In early January Poor Packets identified practically ten,000 vulnerable hosts working the unpatched VPN were being identified in the US and above 2,000 in the British isles. Citrix pushed out firmware updates on January 24.
