A massive data breach has affected hundreds of Miami-Dade County employees, according to two independent NBC 6 sources.
NBC 6 has confirmed county employees' personal information is being used to file fraudulent unemployment claims and commit credit card fraud.
It is still unclear if the data breach, which could date back to the last year, was internal or external, but Miami-Dade County's human resources department is busy contacting all the employees who were targeted.
"I would not wish this on anyone," siad Farren Oglesby, who has worked in the Miami-Dade grants department for 14 years.
Oglesby's boss told her someone had filed an unemployment claim in her name, stating she was let go in October and now she is worried it will keep her from getting real unemployment benefits in the future if need be.
"I was shocked, I was just shocked," she said.
And it wasn't just the unemployment claim: a debit card was opened in her name at the same time, writing out checks for more than $13,000.
"It's exacerbating trying to clear your name for something you didn't do -- my good name and my good credit," Oglesby said.
NBC 6 has learned federal officials at the U.S. Inspector General's Office are taking the lead on the investigation because it deals with fake unemployment claims. The Miami-Dade Police Department has confirmed they have been assisting the U.S. Department of Labor with the investigation for several weeks.
It is still unknown if the data breach has extended outside of Miami-Dade County.
