Security Intelligence
💡 Prototype Pollution Attacks
Prototype pollution manipulates JavaScript object prototypes to inject properties that affect all objects in an application. This can lead to denial of service, property injection, and in some cases remote code execution in Node.js applications.
💡 Zero-Day Vulnerability Markets
Zero-day vulnerabilities command premium prices in both legitimate and criminal markets. Government agencies, defensive security firms, and criminal organizations compete for these undisclosed flaws, creating a complex ecosystem around vulnerability discovery and disclosure.
