The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
Additional information can be found at:
- OpenSSL 1.0.1 through 1.0.1f
- OpenSSL 1.0.2-beta
This flaw allows a remote attacker to retrieve private memory of an application that uses the vulnerable OpenSSL library in chunks of 64k at a time.

While the number of services affected by the OpenSSL flaw known as Heartbleed has decreased, the Shodan search engine has still found nearly 200,000 vulnerable devices.

According to the report published by Shodan , the list of top affected organizations includes IT giants like Amazon, Verizon Wireless, German ISP Strato, OVH, 1&1 Internet, and Comcast.The most affected product is Apache HTTP Server (httpd), in particular versions 2.2.22 and 2.2.15. Top operating system is Linux 3.x, followed by Linux 2.6.x and Windows 7/8. More than 70,000 devices run services with expired SSL certificates.
I don’t see these current findings as a ‘we haven’t patched Heartbleed’ issue, it’s another example of what happens without regulation and standardization, without user education and best practices, coupled with the ‘security as an afterthought’ mentality.
