AdamX: Cosine similarity meets gradient descent
Researchers propose AdamX, a cosine-similarity-based first-order optimizer with variance rectification that matches Adam-class convergence across benchmark datasets and architectures.
The paper introduces AdamX, a first-order optimizer that uses cosine similarity as an adaptive mechanism for controlling update magnitudes, plus a variance rectification scheme for smoother optimization early in training. The method is described as scalable, model-agnostic, and straightforward to integrate into existing pipelines. Empirically, AdamX shows competitive convergence rates measured by epochs to reach performance thresholds under a fixed hyperparameter budget, with code and experiments released on GitHub.
ClickFix Campaign Compromises 31 Orgs, Abuses Polygon Blockchain
A ClickFix social engineering campaign compromised 31 organizations, abusing the Polygon blockchain via EtherHiding for dynamically updated command-and-control.
The campaign uses ClickFix-style social engineering to compromise victims, with 31 organizations affected. It employs EtherHiding to dynamically update its command-and-control server, abusing the Polygon blockchain as an attacker-controlled address book. This blockchain-based C2 approach makes the infrastructure more resilient and harder to take down.
