03STRATEGIES & TACTICS

SUPABASE MCP CAN LEAK YOUR ENTIRE SQL DATABASE

Attackers can exploit Supabase's Model Context Protocol (MCP) to leak SQL databases by embedding malicious commands in support messages. Developers using AI assistants like Cursor to review tickets can unintentionally execute SQL queries with elevated privileges, bypassing security. LLMs can't distinguish between user data and instructions, enabling crafted messages to trigger unauthorized database access and data exfiltration through the support interface.

ADVANCING PROTECTION IN CHROME ON ANDROID

Google's Android Advanced Protection now integrates with Chrome to enhance security for high-risk users, such as journalists and officials. It provides three key features: enforcing HTTPS everywhere, full site isolation on devices with 4GB+ RAM to prevent data leaks, and disabling JavaScript optimizations that are often exploited in V8 security bugs. These options, which have performance trade-offs, can be enabled by enterprises and users through Chrome's privacy settings and policies outside of Advanced Protection.

OPENAI TIGHTENS THE SCREWS ON SECURITY TO KEEP AWAY PRYING EYES

OpenAI has implemented stricter security measures to prevent information leaks and poaching. The new measures include “information tenting” policies that limit access to sensitive algorithms and new products, isolating proprietary technology in offline computers, implementing biometric access controls for office areas, and a “deny-by-default” internet policy where explicit approval is required for external connections. OpenAI reportedly also increased physical security at data centers and expanded its cybersecurity personnel.
