🚀 Glad to present the new release zDNS v0.1.3! 🎉

Following Zero Trust practices, I recently wrote and am slowly beginning to introduce new “blackhole” functionality into the OpenBLD.net DNS ecosystem

zDNS is a DNS server that puts security and control over DNS queries at the center. With new functionality, zDNS now supports regular expressions in hosts.txt files, allowing more flexibility in configuring allowed queries. Now you can use the power of regular expressions to precisely control permissions, including subdomains and patterns.

Main features:

🛑 Denies all DNS queries by default.
✅ Allows you to configure allowed requests through the hosts.txt file.
🔄 Uses balancing strategies to ensure reliable operation with DNS servers.
🛠Easily customizable via YAML configuration.
🔜 Prometheus metrics coming soon

Additional protection of your infrastructure or testing requests with zDNS is possible and may be useful to you! Download the latest version here and start using a DNS server with powerful customization options:

/ Prevent credential exposure with OIDC for GitHub Actions

Many different CI/CD patterns that cause us to raise our eyebrows. One situation in particular that we encounter relatively often is the unsafe use of AWS credentials.

OpenID Connect is an authentication standard, which when coupled with GitHub Actions, offers a more secure alternative for authentication when compared to utilizing traditional access keys..:

/ Info Stealing Packages Hidden in PyPI

The identified packages—nigpal, figflix, telerer, seGMM, fbdebug, sGMM, myGens, NewGends, and TestLibs111—exhibit attack methodologies similar to those outlined in a Checkmarx blog post published four months ago...

The packages released before December 2023 are very similar to those discussed in earlier blog posts. Specifically, they deploy Whitesnake PE malware if the victim’s device runs on Windows, or they can deliver a Python script designed to steal information from Linux devices..:
