After a week away recovering from too much turkey and sweet potato casserole, we’re back for more security news!

This week, a US federal court has ruled that NSO Group is no longer allowed to use Pegasus spyware against users of WhatsApp. And for their trouble, NSO was also fined $4 million.

F5 is unintentionally dabbling in releasing the source code behind their BIG-IP networking gear, announcing this week that an unknown threat actor had access to their internal vulnerability and code tracking systems.
