Memcached – Not secure, Not Patched Fast Enough
Recently high profile vulnerabilities in systems were used to unleash several global ransomware attacks that greatly impacted organizations. These types of vulnerabilities were previously patched and could have been addressed by organizations before the attacks commenced. This is just the latest example in a long line of threats that are successful in large part because of the inability for patches to be applied in a timely and effective manner. In late 2016 Talos disclosed a series of vulnerabilities in a software platform called Memcached. After releasing the vulnerabilities Talos has been monitoring the amount of systems that were vulnerable as well as the rate at which they have been patched. This blog will give a quick overview of the vulnerabilities and discuss the unfortunate findings of the Internet wide scans that we have been conducting over the last six months.
