Bookmakers William Hill under siege from DDoS internet flood

IT admins are having a hell of an evening? You can bet on it! Well, on another website

William Hill is currently on the receiving end of a Distributed Denial of Service attack.

Many of the bookie's sites went down on Tuesday and have remained unable to provide much better than intermittent service into Wednesday due to an ongoing cyberattack.

A spokesman for William Hill confirmed the attack to The Register, stating: "The online services of William Hill were intermittently impacted during the course of yesterday following Distributed Denial of Service (DDoS) activity by third parties."

"This follows a significant increase in DDoS activity experienced by a number of online companies over recent weeks," the spokesperson continued, presumably referring to the Mirai botnet incident.

There are indeed signs that Mirai bots are today throwing at least some traffic at the bookmakers' 141.138.130.0/24 and 141.138.131/24 IP addresses.

"While the attempt at disruption is ongoing our technical teams were able to restore services last night," the spokesperson added, although complaints to The Register continued into this afternoon.

William Hill said it apologised for any inconvenience caused to customers.

Considering the company's H1 revenue of £814m [PDF], the 24-hour outage could have cost the publicly-listed company roughly £4.4m, although the true figure is likely to be less as the outage affected only its online services and did not strike during any notable sports events. ®
