Dutch cable operator Ziggo has experienced network problems for a second time in a week, following a DDoS attack. Service disruptions were experienced throughout the country, and Ziggo said around 60 percent of its customers were affected, NU.nl reports. A Ziggo spokesman said the latest attack was worse than the first. The attack targeted Ziggo’s DNS servers, leaving many customers without internet access. At around 04.00 hours 20 August the company brought the attack under control. The company said it’s started an investigation into the attack and measures it can take to prevent future incidents. In a notice to customers, the company said it was doing everything it could to put an end to the problems and it would be implementing changes to its network as a result of the attack. This will result in a restart of customer modems, which may be without service for several minutes while the changes are implemented. The company said in a statement that it was also working with the National Cybersecurity Centre and Ministry of Justice after several videos with threats against Ziggo’s office were placed on social media. Ziggo said it was taking the threats very seriously and had filed a complaint with the police. Meanwhile the Dutch mobile operators KPN, Vodafone and T-Mobile reported a sharp increase in data traffic during both Ziggo attacks. A spokesman for Vodafone said data traffic doubled both times on its network. Source: http://www.telecompaper.com/news/ziggo-suffers-new-ddos-attack–1098223
