Critical vulnerabilities in MikroTik RouterOS are being actively exploited. Immediate update recommended
The CERT Polska team has identified and coordinated the disclosure of six vulnerabilities in MikroTik RouterOS. Combining two of them allows an attacker to take full control of the device without authentication if the device supports remote access using the SSH protocol. To make this chain easier to identify, we have given it a common name, MikroTrick:

| 5 | Building Linux eBPF/XDP apps on macOS (Apple Silicon)
I spend a lot of time building high-performance DNS filters and network tools in Go. My primary development machine is an Apple Silicon Mac, but all the production deployments target Linux/AMD64 servers.
Recently, I started heavily integrating eBPF and XDP to drop abusive traffic (like random subdomain attacks) before it even hits the Go networking stack. However, compiling C eBPF code locally on macOS has always been a pain due to the missing Linux headers and the architectural differences...
I wrote down the exact step-by-step process, including a workaround for the notorious Debian multiarch header issue (asm/types.h) and a neat little smoke test using bpftool inside the container..:

| 9 |  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. 🚀
