This is because social media can give you instructions on how to access other aspects of an online identity of the victim . " Social media and other credentials , including usernames and passwords , can often be used as an entry point for launching an attack on the victim's account in a number of other sites , " said Juniper Networks security expert , Michael Callahan , as reported by the Telegraph , Monday ( 31/3 / 2014 ) .
Callahan explained that a number of people tend to use the user name and password are the same , so if one account hacked then the hacker can gain more valuable information such as online banking account or e - commerce . For example , he said , if someone's account information on a website is stolen , criminals may be able to access information on the victims of 10 other sites .
" Theft of individual account information can be used as a ' weapon ' account outwit friends, family , and co-workers for additional financial gain , " he continued .
