WannaCry still a concern for millions of computers

Two years after NSA tools wreaked havoc on global computer systems with a threat to WannaCry ransomware, millions of computer systems continue to be at risk.

Data generated by Shodan reveals that there are as many as 1.7 million Internet-connected endpoints that are still vulnerable to the exploits, Engadget reports.

The most vulnerable devices, more than 420,000, are recorded to be in the US. However, there could be potentially millions of other devices connected to those infected servers.
