Linux got wrecked by backdoor attack – by Fireship

If you are terrestrial, you may have heard about the highly sophisticated and meticulously planned attack on the XZ compression tool, which affects various Linux distributions including Debian CI and openSUSE, that has caused alarm in the open-source community. This supply chain attack, considered one of the most well-executed of its kind, allows an attacker to execute code on a machine through a secret back door. The malicious code is not present in the source code but is injected during the build process, making it challenging to detect. Researchers are still investigating the back door’s workings, which involve obfuscations and a requirement for the attacker’s private key to send a payload. The potential impact of this attack is significant, as most servers on the internet are Linux-based. The attacker’s identity remains unknown at this time. So, keep your linux-distro always updated!!!

Our good friend Jeff Delaney discusses the importance of having a seamless payment form experience for validating business ideas. They share their past struggles with implementing payment forms using Authorize.net and how Stripe saw an opportunity to optimize this experience for developers. Jeff shows us how to implement Stripe payments in software-as-a-service products and introduces Stripe Checkout. However, generally, the user is redirected to a third-party website during the checkout process, which can break brand consistency. To solve this issue, the speaker explains how to embed Stripe Checkout directly into a website using a React Server Component in Next.js.
