Arlington city staff foiled a cyber attack that was set up to steal nearly $2 million in city funds.
City spokeswoman Rebecca Rodriguez said sophisticated online attack targeted $1.8 million in city money.
The city's treasury staff recently noticed some irregularities in several city accounts.
"It was almost like any kind of fraudulent credit card transaction that you would notice in your personal account -- it was noticed here in the city," Rodriguez said.
City officials said the city treasury office found that fraudulent accounts had been set up to steal city funds.
"They were able to actually stop it," Rodriguez said. "They contacted the bank and, at that point, the work began immediately to reverse the transactions which had occurred."
Because the attack is still under investigation, the city said it can't go into great detail about the matter.
"The important thing to remember here is that there were no tax dollars actually lost," Rodriguez said.
While an attack was stopped this time, Arlington officials said they are always looking for ways to step up security in this increasingly digital world.
"Every day, there are different risks developing, and you don't know what's on the horizon, and it's a continuing challenge to make sure your systems are where they need to be to meet those challenges that are developing," Rodriguez said.
