We are seeing a high volume of blocked #DNS queries to the domain linked to the #Mozi botnet and the #React2Shell exploit. This identified malicious domain is provided by our #threatintel partner, ThreatSTOP.

Our proactive DNS filtering is currently preventing these connections to keep your devices secure.

Enjoyed our time this week at Domain pulse 2026, discussing a variety of topics, including the need for more collaboration and mutual support amongst the European infrastructure community in light of the barrage of legal action in recent years which threaten #internetintegrity & #internetfreedom.

In the absence of that, the alternatives are not palatable.

We've written much about this. Let us know what you think - or more importantly, how you can help!
