Hacker Leaks Credentials Of 515,000 Servers, Routers & IoT Devices

A large trove of data containing Telnet credentials has been posted by a hacker this week. The credentials belonged to various servers, IoT (Internet of Things) smart devices and home routers. The list contains data of more than 515,000 devices including IP addresses of each device, user ID and password for Telnet.

Previously in August 2017, a list containing 33,000 Telnet credentials of home routers was leaked by a hacker.

The hacker on being asked the reason for publishing the list said that he updated his DDoS service to a new model instead of working on IoT botnets. The new model is based on using high output servers by renting them from cloud service providers.

The list published by the hacker contains the dates of October and November which raises the speculations that some of the devices in the list must have changed their passwords and may be running on different IP addresses now.

The credential will be of no use for basic level hackers. However, experts have clearly stated that the leaked ..
