The New York Stock Exchange withstood an attack Monday by hacker group Anonymous, with its website appearing to have been only briefly affected.

NYSE.com appeared to slow down and perhaps go offline briefly between 3:35 p.m. and 3:37 p.m., media reports said, but there was no interruption to trading on the stock exchange and the public website immediately returned to normal.

Anonymous had warned earlier that its attack would come at 3:30 p.m. on October 10.

The exchange’s online security boss E.J. Hilbert told Bloomberg the attempt was “like four nine-pound weaklings running into a Sumo wrestler.”

Anonymous had boasted that it would “erase” the stock exchange from the Internet, The Wall Street Journal reported.
