Security Intelligence

💡 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.

💡 Bulletproof Hosting Ecosystem

Bulletproof hosting providers deliberately ignore abuse complaints, creating safe havens for malicious operations. These providers often operate in jurisdictions with weak cybercrime enforcement, offering services specifically marketed to criminal organizations.
