Roughly 200,000 Devices still affected by the Heartbleed vulnerability

Pierluigi Paganini January 23, 2017

More than two years after the disclosure of the HeartBleed bug, 200,000 services are still affected.

Systems susceptible to Heartbleed attacks are still too many, despite the flaw was discovered in 2014 nearly 200,000 systems are still affected.
Shodan made a similar search in November 2015 when he found 238,000 results, the number dropped to 237,539 results in March 2016.
The Heartbleed Bug, tracked as CVE-2014-0160, is a serious flaw in the popular OpenSSL library that allows an attacker to reveal up to 64kB of memory to a connected client or server.

Now the Shodan CEO John Matherly revealed that more than two years after its disclosure, about 200,000 services remain affected by the Heartbleed flaw due to the usage of unpatched OpenSSL instances.

Most of the vulnerable installations are located in the United States (42,032), followed by Korea (15,380), China (14,116), and  Germany (14,072).

Heartbleed vulnerability devices

According to Matherly, 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. According to the report published by Shodan, more than 70,000 devices run services with expired SSL certificates.
