CHARLOTTE, N.C. — As Charlotte leaders were trying to control September's violent protests, an international hacking group was trying to prevent them from having access to online resources.
The attack was uncovered after the group anonymously called Eyewitness News reporter Joe Bruno.
Cyber attackers successfully took down Charlotte's website during one of the most chaotic nights in the city's recent history.
"It is not easy. It requires a lot of resources," UNC Charlotte professor Muhammad Shehab said of the attacks.
According to Shehab, Charlotte fell victim to what's known as a "denial of service" attack.
A hacking group used bots to excessively request the city's website.
On the second night of the protests, the city said its site, charlottenc.gov, received around 20,000 clicks per second.
Normal traffic is 1 percent of that.
"They flood the server with requests, when the flood the server with requests, the service runs out of resources," Shehab said.
According to Homeland Security, during a denial-of-service attack, attackers may be able to prevent access to email, online accounts and other restricted information.
Security expert Walter Kimble said cyber-attacks are becoming more common across the nation.
"We need to keep our guard up," Kimble said. "They are very unnerving when they occur because they undermine the portion of our availability our government to function."
An international hacking group called New World Hacking took responsibility for the attack on Charlotte's site.
New World Hacking has taken credit for taking down major websites in the past including ESPN, Twitter and Netflix.
The group claimed to have access to personal information of city employees, but a spokesperson for the city said there was no data breach.
City of Charlotte responds
In response to questions from Channel 9, the city of Charlotte released a lengthy statement detailed its encounters with New World Hacking.
"The City of Charlotte’s website,
, was unavailable to users during the early morning hours of Sept. 22, 2016," city spokesperson Jordan-Ashely Walker, said. "At no time during the event was the City’s website hacked, nor was any private information compromised."
Walker acknowledges Charlottenc.gov experienced a denial-of-service attack.
"This resulted in an error message or a slow response when users attempted to access the site," she said.
According to Walker, the city has enhanced its security systems to prevent similar attacks. Walker also denies the hacking group's claims that it obtained personal information and emails of city employees.
IT staffers were forced to work around the clock because the attack disrupted city services.
And as the world was watching havoc on Charlotte's streets the city's main source of information wasn't functioning.
"I think it has the potential to get worse," Kimble said. "We are at the point now where our local governments need to respond to the threat now so it doesn't get worse
While the attack last fall, wasn't crippling city leaders said they recognize the threat and have enhanced security systems to prevent another denial of service attack.
They aren't discussing the new system so hackers can't figure out a way around it.
An interview request with New World Hacking wasn't returned. A tweet posted by the group claims the group is no longer functioning.
