I fucking love #Resolver by #VerucaSalt. Comes out of the gate strong and doesn't fade, IMO.

On the other hand, we have #Resolver!

Advanced and mature package that offers a somewhat heavier scope. It lacks type safety, and often, missing registrations are only discovered through runtime crashes. 😬

However, it can be wrapped with an abstraction.

A supply chain attacks where the vector relies on #dns spoofing and #dnnsec is of no use:

I suppose the whole idea of "trusting" some random #resolver (from your ISP or not) was never a good idea.

PlushDaemon compromises network devices for adversary-in-the-middle attacks

ESET researchers have discovered a network implant used by the China-aligned PlushDaemon APT group to perform adversary-in-the-middle attacks.

Anyone have a tool/recipe/howto on (continuously) measuring #DNS server #performance (my local #resolver)? My local network has weird connection setup delays that I want to look at.

Preferably not something that needs a full #Grafana setup that I don’t have, but if needs must, it’s ok.

This week we will be at #NetworkX in #Paris! We are bringing our brand #new #opensource #secure #wifi #router - #OmniaNG! If you couldn't make it to #LinuxDays last week, here is another chance to see it IRL! You can also visit our #stand to talk to us about other #CZNIC projects like #Bird and #Knot #Resolver - #routing and #dns. See you in Paris!
