I might move the Dutch Public Prosecution Service (OM) Citrix Netscaler incident out to a different thread, but the latest update an hour ago from local media is that they are still without internet and remote access, and they're working on several alternatives to continue criminal trials.
I expect we're going to see a wave of Netscaler incidents over the coming months, although how many will publicly disclose is another issue - the Dutch are culturally transparent.

The Canadian government cyber centre are this weekend recommending all orgs review historic logs for #CitrixBleed2 compromise, and reset all user sessions https://www.cyber.gc.ca/en/alerts-advisories/vulnerabilities-impacting-citrix-netscaler-adc-netscaler-gateway-cve-2025-5349-cve-2025-5777-cve-2025-6543
The Dutch Public Prosecution Service (OM), which took their systems offline due to #CitrixBleed2 on Friday, are saying they will be offline for weeks. https://nos.nl/artikel/2575857 HT @moartn@tacobelllabs.net
There’s a bit more in situation at the OM on Netscaler here: https://www.volkskrant.nl/binnenland/openbaar-ministerie-mogelijk-nog-weken-afgesloten-van-internet-probeert-impact-op-rechtszaken-te-beperken~b6e19434/
The OM say they patched quickly (and my scan data backs this up - they patched around June 24th) however it appears somebody got in (or took a session cookie) before patching took place and now they’re trying to contain the situation.
The NCSC are strongly advising orgs to follow the advice on my blog re #CitrixBleed2, in hindsight I probably shouldn’t have drawn the logo in MSPaint and titled a section “China goes brrrr”.
I think this thread exposes something about the cybersecurity industry and org posture btw - it almost all runs on Windows and EDR telemetry, hence why there’s little info on this from vendors (Netscaler is closed box appliance - they’re flying blind) and why orgs aren’t seeing anything, they don’t know how without vendors.
I keep contacting orgs and they have no idea they are compromised or how to investigate.

The Dutch Public Prosecution Service #CitrixBleed2 incident rolls on - NRC report on an email from the Director of their IT service, where they say “It is clear that it’s a massive and dramatic incident”.
