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).
