Law enforcement officials are investigating a possible cyber attack on the City of Chicago’s website, a source told the Chicago Sun-Times.

The website— — at one point appeared to be down Sunday morning. Parts of the site, however, returned — at least intermittently — shortly afterward.

“We are aware of the potential issue with the city’s website and are working with the appropriate federal authorities to address the situation,” said Pete Scales, a spokesman for the mayor’s office.

Chicago Police Supt. Garry McCarthy, speaking to reporters in Grant Park, said he did not have specifics on the attack.

“There have been some cyber attacks,” he said. “I don’t have a lot of information on that. .... We’ve had some technical difficulties. I’ll have to drill down on that.”

On, a YouTube video was posted that says they have started “an operation toward the Chicago police department and its websites.” The video was later taken from public view.

In a statement on that web site, a groups responsibility and refers to itself as AntiS3curityOPS. It also references the cyber activist band of hackers known as Anonymous.

“We are actively engaged in actions against the Chicago Police Department, and encourage anyone to take up the cause and use the AntiS3curityOPS Anonymous banner. For those able, should be fired upon as much as possible. We are in your harbor Chicago, and you will not forget us.”

Jeff Cramer, who heads the Chicago office for Kroll Advisory Solutions, said his firm has been for months helping companies around the city secure their computer systems as they braced themselves for a cyber attack in and around the NATO Summit.

“What we’re starting to see more of are these cyber attacks because you can do a lot more damage hacking into these companies’ systems than you can by throwing a rock through the window,” Cramer said.

By using the name “Anonymous” in the video, Cramer said the individual appears to be linking himself or herself to the hacking group Anonymous. “It is a fact that private companies are more and more worried about this kind of attack.”
