Hackers reportedly cracked into the Web sites of more than 49 House members overnight and flooded their pages with anti-Obama attacks.

The breach, which occurred after Obama delivered his first State of the Union address to a joint session of Congress Wednesday night, reportedly targeted both Republicans and Democrats, according to Politico.com.

The home page for the Republicans on the House Oversight Committee reportedly read: "F--- OBAMA!! Red Eye CREW !!!!! O RESTO E HACKER !!! by HADES; m4V3RiCk; T4ph0d4 -- FROM BRASIL."

The House members whose sites were hacked include Reps. Joe Wilson, R-S.C.; Zoe Lofgren, D-Calif.; Duncan Hunter, R-Calif.; Peter Welch, D-Vt.; Phil Roe, R-Tenn., Charlie Wilson, D-Ohio, John Tierney, D-Mass., Charles Gonzales, D-Texas, Mike Coffman, R-Colo., and others.

The Red Eye Crew claimed responsibility for the incident. The group previously claimed credit for other high-profile hacks, including cyber attacks on Virginia's Old Dominion University and a New York advertising firm.

Jeff Ventura, spokesman for the House chief administrative officer, said the sites were managed by a private vendor -- GovTrends of Alexandria, Va.

Most House Web sites are managed totally by House technicians but individual offices are permitted to contract with a third party to manage new features and updates.

Ventura says GovTrends let its guard down while performing an update, allowing the hacker to penetrate sites of individual members and committees overnight.

Ventura said 18 House sites managed by GovTrends were defaced last August. The House is looking into continued use of the company, he said.
