The online world can be full of fraud opportunities.
Hackers breached a third party marketer and may have had access to client e-mail addresses held by many well–known companies.
Several dozen companies were affected, including tech retailers like Best Buy, TiVo and Target.
Credit–card companies like Chase, Citi and Capital One were on the list, too.
The marketing company, Epsilon, says if you’ve done business with one of the companies on that list, there’s a good chance your email address was affected.
One suggestion they have — creating a dummy e-mail address that you use only for e–commerce and company correspondence.
