If you live in Colorado or California and shop at Safeway, it's time to check your account balances and make sure there's been no fraudulent activity.
Although it's limited to only a handful of Safeway stores, thieves have been able to successfully compromise certain checkout lanes by installing skimmers, which are attached to places people swipe their credit and/or debit cards.
Once in place, skimmers steal the magnetic strip information from your card. Then, thieves use this information to clone your card, and once they have a clone, they can drain your bank account or run up huge bills and trash your credit before you even know it.
Because skimmers often require time and skill to install, most skimmers installed at retailers' checkout lanes signal an inside job.
For now, Safeway isn't releasing the names of the affected stores, but banking sources for security blogger Brian Krebs say they have traced it to Arvada, Conifer, Denver, Englewood and Lakewood in Colorado; and Castro Valley and Menlo Park in California.
What can you do to stay safe and keep your credit information private?
