PORTLAND On Monday, Target continued its efforts to win back customers, as news of more major retail security breaches continued to spread around the globe.

While Target acknowledged 110 million accounts have been affected by the hackers who stole card information, pin numbers and now email and home addresses during the holidays, Reuters reported Monday that eastern European hackers are likely responsible for the attacks on Target, Niemen Marcus and at least three other national retail chains that have yet to come forward.

The high-end department store Neiman Marcus confirmed Sunday that was a victim of a hack similar to the one experienced by Target. The number of affected accounts hasn't been released yet.

The slow revelation of these incidents has local experts worried that the public still doesn t know the scale of the crisis.

Tech and consumer experts like Ken Westin, of Portland, are worried the slow rollout of just how bad Target s breach was, could mean even more information was stolen from its database, called GuestID.

He says that system could include information like your marital status, salary, products you buy, or even if you have kids.

Portland State University business marketing professor Dr. Lauren Beitelspacher was a Target victim herself. Her bank contacted her, saying her account was one of those hacked, but luckily there hadn't been any fraudulent charges. She's using it as a lesson in her classes.

It's very bad for Target because it makes people less trustful of them. However, probably right now Target is the safest place to shop because Target is going to do everything they possibly can so something like that doesn't happen again, Beitelspacher said.

In the wake of the breach Target has started what experts are calling an expensive and bold move to provide a year of free credit monitoring to its U.S. customers. However, it might make nervous shoppers even more frazzled. The offer means you'd have to provide even more private information about yourself, including your social security number to Experian, the company that's handling the monitoring.
