Short-lived and IP address certificates are now generally available from Let’s Encrypt. These certificates are valid for 160 hours, just over six days. In order to get a short-lived certificate subscribers simply need to select the ‘shortlived’ certificate profile in their ACME client. Short-lived certificates improve security by requiring more frequent validation and reducing reliance on unreliable revocation mechanisms. If a certificate’s private key is exposed or compromised, revocation has historically been the way to mitigate damage prior to the certificate’s expiration. Unfortunately, revocation is an unreliable system so many relying parties continue to be vulnerable until the certificate expires, a period as long as 90 days. With short-lived certificates that vulnerability window is greatly reduced.

Introduction Netcat is a tool that reads and writes data across network connections, using TCP or UDP protocol. Netcat has been referred to as the TCP/IP / networking swiss army knife. In this article we’ll look at different applications of netcat and how it can be useful in day to day activities of a pentester, security professional, sysadmin etc… If you would like to test out these commands in a lab environment without the need to install them on your own machine have a look at my scenario on CYBERRANGES using the link below.

Like Heroku, but you own it.

Hello, I did not find a new image for the security release Security/CVE RELEASE.2025-10-15T17-29-55Z, on quay.io nor DockerHub. Is it expected? If it isn’t, can you please push a new release for this installation method? Thank you.

Microsoft is bringing GitHub into its AI engineering team. It’s part of an AI shakeup, following the GitHub CEO resigning.

To prioritize the safety and security of the ecosystem, Kubernetes SIG Network and the Security Response Committee are announcing the upcoming retirement of Ingress NGINX. Best-effort maintenance will continue until March 2026. Afterward, there will be no further releases, no bugfixes, and no updates to resolve any security vulnerabilities that may be discovered. Existing deployments of Ingress NGINX will continue to function and installation artifacts will remain available. We recommend migrating to one of the many alternatives.
