A quarter of British teens try to access their pals' Facebook accounts, a new survey has found.
The poll of 1150 under-19s showed that the most common way of access was by "cracking" each other,s passwords.
It was seen that about 50 percent of youngsters who accessed other accounts used their personal computers or those at school.
Teens said they mainly did it for fun while 21 percent confessed they wanted to cause trouble.
Twenty percent of those who admitted to hacking believed they could make money from it with 5 percent describing it as a career option.
The respondents taking part in the survey, commissioned by Tufin Technologies, maintained anonymity.
Seventy-eight percent knew hacking was not right.
"Playing around with computers and trying to understand the system can be leveraged for good and bad purposes," the BBC quoted Reuven Harrison, co-founder of Tufin Technologies, as saying.
Harrison added: "There's a fine line at which point it becomes something bad. Children don't always understand where that line is."
