Threat actors with ties to North Korea have likely become the latest to exploit the recently disclosed critical security React2Shell flaw in React Server Components (RSC) to deliver a previously undocumented remote access trojan dubbed EtherRAT. “EtherRAT leverages Ethereum smart contracts for command-and-control (C2) resolution, deploys five independent Linux persistence mechanisms, and Read More
Shanya is the latest in an emerging field of packing malware, selling obfuscation functionality in order to help ransomware actors reach their target. Read More
Four distinct threat activity clusters have been observed leveraging a malware loader known as CastleLoader, strengthening the previous assessment that the tool is offered to other threat actors under a malware-as-a-service (MaaS) model. The threat actor behind CastleLoader has been assigned the name GrayBravo by Recorded Future’s Insikt Group, which was previously tracking it as […]
Real-world reasoning: How Amazon Nova Lite 2.0 handles complex customer support scenariosArtificial Intelligence This post evaluates the reasoning capabilities of our latest offering in the Nova family, Amazon Nova Lite 2.0, using practical scenarios that test these critical dimensions. We compare its performance against other models in the Nova family—Lite 1.0, Micro, Pro 1.0, and Premier—to elucidate how the latest version advances reasoning quality and consistency.

The Machine Learning “Advent Calendar” Day 9: LOF in ExcelTowards Data Science In this article, we explore LOF through three simple steps: distances and neighbors, reachability distances, and the final LOF score. Using tiny datasets, we see how two anomalies can look obvious to us but completely different to different algorithms. This reveals the key idea of unsupervised learning: there is no single “true” outlier, only definitions. Understanding these definitions is the real skill.
