• Noticing command and control channels by reviewing DNS protocols

  Malicious software pieces installed in computers call home. Some of them can be noticed because they perform DNS lookup and some of them initiates connection without DNS lookup. For this last option, this is abnormal and can be noticed by any Network Detection and Response (NDR) tool that reviews the network traffic by at least two weeks.

  Most companies do not have money to afford a NDR, so I'm going to show you today an interesting tip that have worked for me to notice APT calling home when they perform DNS lookup.

• Stop deploying web application firewalls

  In addition to slowing down every request, you also need significant additional RAM for buffering requests. Since not a single byte in the buffer can be flushed to the backend server until the WAF completes its analysis, you need several gigabytes of RAM to store request bodies. Servers like nginx buffer requests by default, but enough large concurrent requests (like pushing a container image) can make a buffering web server run out of RAM. When using a WAF, every server becomes a buffering web server, which is simply incompatible with many types of applications.

  I know computers are fast and hardware is cheap, but we shouldn't be spending that kind of CPU and RAM on WAFs unless they're a really effective security tool. But they aren't, as you'll see next.

• Frameworks Cover Up Skill Issues, And That's a Good Thing

  Here’s the quote that sticks with me:

  " My prior experience hurt me in this case. I was thinking about the program, and how I could write something that was concise and clean. The guy who wrote the skull demo wasn’t worried about any of that. He didn’t care about what the program looked like or how maintainable it was. He just wanted a way to present his vision. "

• HTML Web Components

  This feature of web components encourages a design of composability. Rather than an empty “shell component” that takes data and (using JavaScript exclusively) renders the entirety of its contents, web components encourage an approach of composing core content with HTML and then wrapping it in a custom element that enhances its contents with additional functionality.

• Use of HTTPS Resource Records

  Good news, everybody -- we have new DNS resource records! Well, not new new, but, you know, newish. You've probably heard of them, or even seen them actively in use, even though they moved from internet draft to formal RFC9460 adoption literally while I was working on this blog post during the last few weeks: the SVCB and HTTPS resource records.
