Critical RCE flaw in Windows IKE Extension now actively exploited
- Engineer — Act: CISA confirmed active exploitation of this critical Windows IKE RCE — patch all Windows systems running IPsec/VPN services immediately; treat as emergency patch given KEV-level signal from CISA warning.
- SOC/IR — Act: Active exploitation confirmed by CISA — hunt for anomalous IKE/IPsec traffic and suspicious activity originating from VPN-adjacent or edge Windows systems since the campaign began; assume-breach sweep warranted for internet-exposed IKE endpoints.
- Leader — Plan: Confirm with infrastructure teams that Windows IPsec/VPN systems are prioritized in the current patch cycle; active exploitation elevates this above routine cadence but it falls short of board-level disclosure unless a breach is discovered.
