A study conducted by the security firm Rapid7 revealed that millions of devices remain exposed to cyber attacks via SMB, Telnet, RDP, and other types of improper configurations. The researchers scanned the Internet for improperly configured services, such as the recently exploited Server Message Block (SMB) and Telnet that were respectively targeted in the WannaCry attack and attacks based on IoT botnets (i.e. Mirai, Persirai) The study also revealed many services that arent encrypted. The most exposed regions are Zimbabwe, Hong Kong SAR, Samoa, Republic of the Congo, Tajikistan, Ireland, Lithuania, Australia, and Estonia.”]
