Cyber expert says tracking plane threats should be easy

ATLANTA — The FBI is hunting for the person or group of people who sent threatening tweets about two flights bound for Atlanta's Hartsfield-Jackson International Airport.
 
Fighter jets escorted the planes to the ground on Saturday.
 
One tweet from "King Zortic" read, "I have a bomb on one of your planes, but I forgot which one I left at the airport. Can you help me find it?"
 
Soon federal, state and local law enforcement surrounded two planes and watched as passengers disembarked the Delta Airlines and Southwest Airlines flights on the tarmac.
 
Cyber expert Greg Evans says Twitter can help the FBI find the person or persons behind the tweet.
 
"This is going to be very simple, and this is what people don't understand. Twitter is going to say, 'This is the IP address of the person who sent this tweet out,'" Evans said.
 
He added that from there, the FBI will have to identify the IP address' service provider; then Evans says it just a matter of time. 
 
"They are going to say, 'It belongs to John Doe, and this is his address, this is his phone number.' Within minutes they can have SWAT team members that same day at their home," he said. 
 
Evans went on to say tracking a tweet from a cellphone is easier than a traditional computer.
 
FBI Special Agent Steve Emmett wouldn't go that far.  He told Channel 2 Action News "King Zortic" is not making it easy.
 
"It's going to be a challenge for our cyber agents in particular," Emmett said.
 
Emmett explained the FBI is working with Twitter and takes threats against aircraft very seriously. 
 
The person or persons responsible face several years behind bars.
