You might know about hacking websites, traffic signboards or radio stations. But now, it’s time to add tornado emergency siren on the target list. Yes, someone hacked every single tornado emergency siren (156 ) in Dallas, TX on Friday night which sounded something like this:

These sirens which are basically used by authorities to warn residents against storm or tornado were caught terrorizing the Dallas city for about an hour and a half picturing the scenario what happens when things go in the wrong hands.

According to Dallas Morning News, the city witnessed three tornadoes a few days back and siren warnings would have been a normal but non-stop sirens on a crystal clear night would have been nothing but an uncertain and terrorizing situation.

While some cracked jokes on Twitter others wondered if the United States was under attack. According to City of Dallas- Office of Emergency Management’s live video session on Facebook “It does appear at this time it was a hack and we do believe it came from the Dallas area.”

“Every time we thought we had turned it off, the sirens would sound again, because whoever was hacking us was continuously hacking us,” Ms. Syed added.
