Rotunda launches stealthy agent-first Firefox fork

Rotunda is an open-source Firefox fork engineered to help AI agents bypass aggressive bot detection. It mimics realistic human mouse movements and typing cadences while exposing a standard Playwright API for seamless integration with existing agent stacks.

// ANALYSIS

Web automation is entering a new arms race where agents must actively disguise themselves as human operators to function reliably.

–Swaps Chromium for a patched Firefox build to evade common Chrome DevTools Protocol (CDP) detection signatures
–Employs a trained RNN to simulate realistic, human-paced typing and mouse interactions rather than instantaneous mechanical inputs
–Built for local execution to leverage residential IP addresses, avoiding the immediate red flags of cloud data center traffic
–Offers a drop-in replacement for standard Playwright browsers, allowing developers to upgrade existing scripts without rewrites

TanStack Router hit by massive supply chain attack

The popular TanStack Router framework was the primary target of a sophisticated npm supply chain attack dubbed "Mini Shai-Hulud," which compromised 42 packages across the @tanstack ecosystem and namespaces for Mistral AI and UiPath. By poisoning the GitHub Actions cache to hijack the OIDC-based release pipeline, attackers published 84 malicious versions carrying valid SLSA provenance while harvesting cloud credentials and installing a destructive wiper payload. The TanStack team has issued an "All Clear" as of May 15, 2026, but the incident marks a significant escalation in the complexity of package manager exploits.

Socket uncovers 'Mini Shai-Hulud' worm in TanStack

Socket's AI security engine flagged the "Mini Shai-Hulud" worm targeting the TanStack ecosystem, which hijacked 84 legitimate package versions via a sophisticated GitHub Actions cache poisoning attack. The malware sought to exfiltrate CI/CD secrets and AI tool configurations before being deprecated within an hour.
