Weak passwords are to blame.
About 15 percent of all home routers are unsecure, according to a study recently released by ESET.
ESET took a look at home 12,000 routers and found that 15 percent had weak passwords with the default ‘admin' being the username.
“During the test, common default usernames and passwords, as well as some frequently used combinations, were tested. It's disturbing that more than one in seven of such simple simulated attacks was successful,” wrote Peter Stancik, ESET researcher.
