Ireland’s National Lottery has become the latest gambling operator to be hit with a distributed denial of service (DDoS) attack.

While nowhere near the recent $1.6b Powerball jackpot in the US, Wednesday’s €12m prize was the biggest the Irish Lottery had offered in 18 months. But unknown hackers knocked the Lottery’s website offline for two hours on the day of the draw.

Interestingly, the attack not only affected the website, but also lottery terminals in retail locations. The attack began at roughly 11:20am on Wednesday but retail systems were back in operation within 90 minutes while the website took about a half hour longer to restore. That night’s draw went ahead as scheduled.

Premier Lotteries Ireland (PLI), which operates the National Lottery, issued a statement saying the attack had been blunted by the company’s anti-DDoS systems, “limiting disruption and restoring all operations within two hours.” PLI stressed that “at no point was the National Lottery gaming system or player data affected.”
