Security researchers identified a new OpenSSL vulnerability, called DROWN( Decrypting RSA with Obsolete and Weakened Encryption ) on March 2016. This attack was focused on servers that use the more secure TLS protocol, which also supports the obsolete SSLv2.This vulnerability allows an attacker to decrypt the highly secured TLS encrypted communication if the server houses SSLv2 cipher support. DROWN was assigned the CVE-2016-0800 id by the us-nert on the march (https://www.us-cert.gov/ncas/bulletins/SB16-067 ). More than 11 million websites that use TLS were vulnerable to DROWN attack.
