The FBI is helping the city of Akron and Akron-Canton Airport investigate their computer systems to learn more about recent attacks that made sensitive information available on the Internet.



“We are looking for internal takeaways to make sure that we have strengthened our system to keep this from happening,” said airport spokeswoman Kristie VanAuken.



A Turkish group attacked the airport on Saturday, revealing names and email addresses of people who participated in contests. Other sections of the airport with more sensitive financial information were not compromised.



The airport is telling about 15,000 people who participated in its contests in the last two years to change the passwords on their email accounts.



The same Turkish group hacked into Akron’s city website May 16 in what Mayor Don Plusquellic called a terrorist attack.



The attack on the city revealed tax files that included names, addresses and Social Security numbers that could be used in identity theft.



The city last week sent out thousands of letters to people whose names were hacked, advising them to monitor their financial accounts closely and call the credit reporting agencies to have their credit frozen. Residents can also call the city’s 311 information line.
