After being contacted by a couple of customers regarding the updates sent out by NCSC (NL) regarding CVE-2025-5777 and CVE-2025-6543 for #NetScaler, I've decided to bundle a set of tests for indicators of compromise into one #shell script.

It wasn't a joke after all.

The popular Go YAML library "gopkg.in/yaml.v3" is officially archived since the first of April 2025.

It's affecting many tools written in Golang that manipulate YAML files, so what's the plan now?

If you hook up a #Fortigate with a Fortinet-encoded (SFP+) DAC-cable to a #Mikrotik CRS, make sure to disable auto-negotiation at the Mikrotik-end and specify the speed manually!

@robbeekmans.bsky.social also published a more generic EUC list I believe.

Jan Tytgat @jantytgat.com · Jan 13

If you're concerned with CTP's, I'm trying to keep up with a list I created.

It won't encrypt a complete file for you and currently only supports "string" and "int" datatypes. Moreover, there are easier ways to encrypt/decrypt files for a ransomware toolkit. 😉

But thanks for seeing the potential! 😅
