DNS is not just about domains. It is about Trust.

Recent supply chain incidents are a strong reminder that modern attacks often start through tools and workflows developers already trust:

• npm packages and dependency updates
• compromised maintainer accounts
• VSCode extensions
• GitHub Actions workflows
• fake installers and update mechanisms

Several recent cases highlight this trend:

• Axios compromised on npm - malicious versions dropped a Remote Access Trojan >
• Compromised VSCode Nx Console >
• OpenAI TanStack npm supply chain attack >
• OpenAI Axios developer tool compromise >
• GitHub unauthorized access to internal repositories >

The key takeaway: supply chain attacks are becoming more relevant to every developer, engineering team, and company.

DNS security should not be treated as an optional layer.

It can provide visibility and control when malicious code attempts to:

• connect to C2 infrastructure
• reach phishing domains
• communicate with fake update servers
• exfiltrate data through suspicious endpoints

If malicious code has already entered the environment, visibility becomes critical...

At this point, the key questions are simple:

• Can you see where it is trying to connect?
• Can you understand whether that connection is expected?
• Can you react before the incident becomes bigger?

OpenBLD.net - Security starts earlier than incident response.

Watch yourself, your emails, your extensions, and your DNS. Peace ✌️

Vishing actors target Entra passkey enrollment (mimics the Microsoft passkey enrollment)

The threat actor registers domains that incorporate the word passkey as part of a voice-enabled phishing (“vishing”) scheme. The threat actor then calls targeted users on the phone in an attempt to persuade them that they need to register a new passkey.:

3 BILLION DNS queries.

Almost +1 billion in one week.

OpenBLD started in 2019 as a homegrown project handling around 35K DNS queries a day.

Today:

→ ~15M queries/hour
→ 4K+ queries/second
→ servers distributed around the world
→ billions of DNS queries processed

And it still runs mostly on regular VPS infrastructure - with plenty of performance headroom left.

Getting here required years of optimizing the entire stack: networking, DNS processing, caching, filtering, load balancing, observability, and the Go code itself.

Now the growth is public too:

Real-time OpenBLD network statistics are live on OpenBLD.net.

From 35K/day to 3 billion.

Still building. 🚀

Fast. Private. Open.
