The Library of Congress computer systems have returned to normal after facing a four-day long cyber attack. 

Library Director of Communications Gayle Osterberg would not comment about the origin of the attack, but praised the IT department’s efforts to keep the agency afloat. The attack began Sunday and caused intermittent outages of service for websites and agencies under the Library’s umbrella, including the U.S. Copyright Office. 

{mosads}In what is known as a distributed denial of service attack, a vast network of computers contacts a target at the same time, overwhelming it with traffic. 

It is a favorite tactic of activists, including Anonymous; pranksters, including the group Lizard Squad that has used it to take down video game networks; and even a few governments, including China, which has in the past tricked the computers of people visiting China’s most popular websites to flood foreign sites seen as threats. 

But a blog post announcing the return to normalcy emphasized that this was a complex attack. 

“This was a massive and sophisticated … assault, employing multiple forms of attack, adapting and changing on the fly. We’ve turned over key evidence to the appropriate authorities who will investigate and hopefully bring the instigators of this assault to justice,” it read.

The blog post noted there may be some “residual issues” from the attack and asked users to submit them to the agency through a web form.
