Indeed, the thing wasthat ransomware threat actors are actively exploiting CVE-2024-1086, giving federal agencies until November 20 to apply the necessary fix or “discontinue use of the product.” But this isn’t a warning just for those federal agencies, it’s one that all businesses need to take note of.
