Looking for employment, Sarah Bailey applied for a customer service position through an online ad.

"It's a shopping, mystery shopper position and you'll be issued packets, assignments with instructions and basically reviews for shops to be going to," Bailey said.

Bailey's first job was with Secret Shop MoneyGram. "I was to deposit it and then withdraw it and then I was to wire it to another representative who was in state or not in state, in country and they were reviewing the pickup process," Bailey said.

Bailey went to her bank to cash the check and drove off with $2,950.

As per the instructions, Bailey said she kept $295 dollars as her fee and wired more than $2,600.

A few days later she was notified the check she had cashed was fraudulent.

The bank promptly debited her account and instructed her to file a police report.

"Unless there is some other type of fraud to your account, the account holder for the most part is gonna be held responsible and they'll suffer the losses," said KSAT Crime Analyst Eddie Gonzales.

A bank representative explained checks are usually cashed based on the payee's account balance, status and relationship with the bank, adding the customer is always responsible for checks presented, fraudulent or not.

Gonzales warns job applicants against using unprotected websites.

"No legitimate company is gonna send you an overage amount and then because you're such a good person we trust you, send us this much of it back, but you can keep this much," Gonzales said.
