1. Abandoned S3 Buckets as a Supply-Chain Attack Vector – Case Study
INFO: Do you remember the researchers who took over the MOBI domain registry by purchasing an old domain? Or the ones who backdoored existing web backdoors? Well, here’s their third case study. This time, they scanned the internet for abandoned AWS S3 buckets— once in use, later deleted, and now available for re-registration. They then used them to attack applications that were unknowingly still relying on those resources. Surprisingly, this was an easy way to compromise several Fortune 500 companies—a must-read for cybersecurity and pentesting enthusiasts.

3. SQLite vs. PostgreSQL – Performance Comparison & Data Migration
INFO: Twilio built a dashboard to analyze blog traffic using SQLite, but as user numbers grew, they questioned whether it could still meet their needs. Tests showed that PostgreSQL could be a better choice in some scenarios. However, migrating data from one database to another is not always straightforward. There’s no definitive winner between the two—each excels in different use cases. If you're choosing a database, benchmarks should reflect your specific workload. For smaller databases, SQLite remains highly competitive under certain conditions.

11. Running DeepSeek R1 (671B) Locally at 3x Lower Cost – Cost Optimization
INFO: A week ago, an article showed how to run the DeepSeek model on a setup costing around $6,000. However, someone found a way to do it three times cheaper a week ago! This article details how to build and configure a server to run the most advanced version of DeepSeek R1 (671B) locally. The setup uses an AMD EPYC 7702 and 512GB RAM to run the full DeepSeek model. It includes advice on recommended hardware components, current prices, and step-by-step instructions on assembly and BIOS configuration for optimal performance. The guide also covers software installation and setup, enabling local AI inference without needing an expensive GPU.

12. Most Commonly Chosen PIN Codes Compromise Your Security
INFO: If you think people come up with four-digit PINs randomly, this study shows that's not the case. About 10% of the population uses the same simple four-digit PIN codes. Some base their PIN on their birthdate, while others use a geometric pattern. Breaking into resources protected by such a PIN often doesn't require checking all possible combinations, because starting with the most popular patterns can drastically shorten the attack time. More details can be found in the article.
