Preventing The Capital One Breach
> Every indication is that the attacker exploited a type of vulnerability known as Server Side Request Forgery (SSRF) in order to perform the attack. SSRF has become the most serious vulnerability facing organizations that use public clouds. SSRF is not an unknown vulnerability, but it doesn’t receive enough attention and was absent from the OWASP Top 10.
> SSRF is a bug hunters dream because it is an easy to perform attack and regularly yields critical findings, like this bug bounty report to Shopify. The problem is common and well-known, but hard to prevent and does not have any mitigations built in to the AWS platform.
