A 45-year-old woman has been sentenced to two and a half years in prison for participating in what the U.S. Attorney's office said was a sophisticated computer hacking and ATM cash out scheme.

U.S. District Judge Steve Jones sentenced Sonya Martin for conspiracy to commit wire fraud. Authorities said she was from Nigeria and Chicago.

U.S. Attorney Sally Quillian Yates said the charges stemmed from a scheme where hackers obtained access into the computer network of a payment processor located in Atlanta.

After compromising the system, the hackers managed to withdraw more than $9 million from more than 2,100 ATMs in at least 280 cities around the world, Yates said.

Yates said Martin was charged with working with a crew that withdrew approximately $80,000 from various Chicago area ATMs.
