Microsoft Teams voice calls abused to push Matanbuchus malware

The Matanbuchus malware loader has been seen being distributed through social engineering over Microsoft Teams calls impersonating IT helpdesk. Matanbuchus is a malware-as-a-service operation seen promoted on the dark web first in early 2021. It was advertised as a $2,500 Windows loader that executes malicious payloads directly in memory to evade detection.

Socket researchers say that the campaign follows threat activity detected since April. Last month, the same acto

Async Queue – One of my favorite programming interview questions

For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been given by us between 500-1000 times across different companies, and upon googling for "async queue interview", I see tons of results. So, it's probably fine for me to blog about it. My main goal with this blog post is to disc

My Database Is My Application: Rethinking Webhook Logic with DuckDB and SQL

My Database is My Application: Rethinking Webhook Logic with DuckDB and SQL Sat May 10 2025 • duckdbsqlwebhooks Back Imagine you need to build a system for processing incoming webhooks. You're probably picturing a familiar setup: a lightweight web server (FastAPI, Flask, Express.js, etc.), some Python (or Node.js, or Go) handlers to parse JSON, a sprinkle of business logic, and then maybe persisting data to a traditional database like PostgreSQL or MySQL. Perhaps you'd toss events onto a messa

Performance Debugging with LLVM-mca: Simulating the CPU

Some time ago I had a performance problem that wasn’t easy to explain by just looking at the code, since the version I expected to be faster was actually slower. Since the problem is simple yet illustrative, I am using it as a showcase on how to debug performance issues using llvm-mca. According to it’s documentation llvm-mca is a performance analysis tool that uses information available in LLVM (e.g. scheduling models) to statically measure the performance of machine code in a specific CPU.
