Botnet census finds 1.2m devices with default passwords

A common “script kiddie” technique to find vulnerable online computer systems is to attempt to scan a range of IP addresses for responsive known services, such as Telnet or SSH, and then attempt to log in using the default username and password. A crude physical analogy would be a burglar who walks from house to house in a neighbourhood, checking to see whether anyone has forgotten to put a lock on their door.
