VPN provider Pulse Secure on Monday urged customers to apply a security patch if they have not yet done so. The company issued the patch last April to address a critical, remotely executable flaw in some versions of its products. Among those believed affected in the ongoing campaign is Travelex, which experienced a massive service disruption this week following a reported ransomware attack on its systems on New Year’s Eve. At least 3,825 Pulse Secure VPN servers remain unpatched and vulnerable to attack as of January 3, 2020.”]
