💡 XML External Entity (XXE) Attacks

XXE vulnerabilities in XML parsers allow attackers to read local files, perform SSRF, and execute denial of service attacks. Many legacy applications and APIs remain vulnerable to XXE due to insecure default XML parser configurations.

💡 State-Sponsored Cyber Operations

Nation-state actors conduct sophisticated campaigns for espionage, sabotage, and influence operations. Their resources exceed typical criminal organizations, enabling zero-day exploitation, long-term persistent access, and attacks on critical infrastructure.
