Security Intelligence

💡 Cross-Site Scripting (XSS) Attacks

XSS attacks inject malicious scripts into web pages viewed by other users. Reflected XSS uses crafted URLs, while stored XSS persists in databases. Both types can steal session cookies, redirect users, or deface websites.

💡 Subdomain Takeover Vulnerabilities

Subdomain takeover occurs when DNS records point to decommissioned services. Attackers claim the abandoned resource and serve content under the trusted domain, enabling cookie theft, phishing, and reputation damage.
