PROMISES FROM THE GROUND UP

Promises in JavaScript aren't always intuitive to use, but they're required to be productive with JavaScript. Promises are needed because JavaScript is single-threaded, which can cause issues when blocking operations like window.prompt() are used. This post dives into the mechanics of Promises, their states (pending, fulfilled, and rejected), and how to work with them using the .then() and .catch() methods. It also covers creating custom Promises, chaining them together, passing data between them, and the modern async/await syntax for a more synchronous-like experience.

SILVER FOX APT EXPLOITS SIGNED WINDOWS DRIVER TO DELIVER VALLEYRAT

Silver Fox APT exploits a Microsoft-signed but vulnerable WatchDog Antimalware driver (amsdk.sys v1.0.600) to disable security processes on Windows 10/11 and deploy ValleyRAT malware, with the driver never being flagged by Microsoft's Vulnerable Driver Blocklist or LOLDrivers database. The attackers bypassed hash-based blocklists even after a patch by changing a byte in the driver's timestamp while keeping its valid Microsoft signature, showing how trusted signed drivers can be weaponized. The campaign exposes gaps in Microsoft's driver blocklist and the need for security teams to use additional verification beyond signature validation, as the malware terminated nearly 200 security processes targeting mainly Asian organizations.

IN A FIRST, SCIENTISTS MAP COMPLETE BRAIN ACTIVITY DURING DECISION-MAKING

Researchers have mapped decision-making at a single-cell resolution across an entire mouse brain. The effort by the International Brain Laboratory, a global consortium of 22 labs, was coordinated by three Princeton labs. The experimental setup involved making mice move tiny steering wheels to control shapes on a screen while recording neural activity using high-density electrodes. The work showed that decision-making is very broadly distributed throughout the brain, including in regions previously thought not to be involved. The coordination of 22 labs worldwide demonstrates the power of large-scale neuroscience.

SEEING LIKE A SOFTWARE COMPANY

Thinking in terms of legibility and illegibility explains many of the things that are confusing about large software companies. It explains why companies do many things that seem obviously counter-productive, why the rules in practice are so often out of sync with the rules as written, and why companies are surprisingly willing to tolerate rule-breaking in some contexts. Increasing legibility often lowers efficiency, but its benefits are high enough that organizations are typically willing to do so regardless. Both the legible and illegible are important - the legible allows organizations to do things that would otherwise be impossible, while the illegible allows for high-efficiency work.
