According to research from Venafi, a vast majority of the world's top businesses are still vulnerable to Heartbleed, which was disclosed a year ago this month. The OpenSSL flaw impacted organizations both large and small, but the latest figures show that 74-percent of the Global 2000 remain vulnerable.
Heartbleed (CVE-2014-0160) was fully disclosed on April 7, 2014. The problematic code was originally introduced to the OpenSSL platform in 2012, but remained undetected until researchers performed an audit.
