From the Trenches
The Pawn Storm campaign targeting government and critical infrastructure with PRISMEX is a reminder that nation-state actors don’t take weekends off. APT28 has been running variations of this playbook for years — spearphishing, credential harvesting, lateral movement — and the infrastructure targeting angle means the blast radius when they succeed is significant. If you’re in any sector that touches critical infrastructure, your threat model needs to account for this level of persistence.
Citrix NetScaler flaws are back on the board, and if you’ve been in this industry for more than a few years you already know what that means. Citrix vulnerabilities get exploited fast and hard. Get your patch cadence tightened on NetScaler assets and verify your WAF rules are actually catching exploitation attempts, not just logging them.
🔧 Patch Priority: Citrix NetScaler — repeat offender with a history of rapid exploitation; treat any unpatched instance as actively compromised until proven otherwise.
