Many websites of the Dutch government were hammered by a distributed denial-of-service (DDoS) attack, the government said on Wednesday. In a statement, the government said the attack targeted the hosting service Prolocation, also knocking out other websites such as that of the satirical publication GeenStijl. It began 10am local time on Tuesday and apparently lasted into the evening. The Dutch National Center for Cyber Security is now coordinating with the government to investigate the attack. Ironically, as GeenStijl pointed out in its own statement, the DDoS took place on Safer Internet Day.
On Thursday, Sweden’s biggest internet service provider, Telia, said that its network had suffered an attack earlier this week from hackers who were apparently trying to target a gaming company. Reports suggest the target was Electronic Arts (EA), which runs some Battlefield services out of the country.
According to Telia, the distributed denial of service (DDoS) attack occurred on Tuesday night and through much of Wednesday, forcing the ISP to toughen up its systems. While it was ongoing, the DDoS made it difficult for thousands of [company]Telia[/company]’s customers to surf the web, watch digital TV and make VoIP calls.
Telia spokesman Marcus Haglund told me Thursday that the attack first hit around 10pm on Tuesday evening, running for around 45 minutes. “Then it calmed down overnight,” he said. “It continued from 10am and was running all through the day and escalated in the night. It ended at 8pm.”
“We have an internal investigation that will run to the bottom of what has happened and what we can do to prevent it in the future,” Haglund continued. “There was a configuration that was a bit lax yesterday that we have corrected. If the same attack was aimed at us or any of our customers, we can say we are not vulnerable in the way we were yesterday.”
Haglund said thousands of customers had been affected. In such attacks, the target’s systems are flooded with data, causing them to stop working. Recent years have seen such attacks grow in severity, with the culprits amplifying them by bouncing the traffic off open servers, notably domain name system (DNS) servers.
The ISP hasn’t named the gaming company that was the target, but the Swedish newspaper Dagens Nyheter reported that it was Electronic Arts (EA), which has offices in Stockholm that develop and run the Battlefield Heroes and Battlefield Play4Free services. The paper quoted F5 Networks security expert Joakim Sundberg as saying the attack used DNS servers for amplification, and that it was perpetrated by the “Lizard Squad” hacker group.
Lizard Squad claimed on Twitter that it had taken down EA’s servers, and has previously claimed responsibility for repeatedly knocking over Sony’s PlayStation Network, Microsoft’s XBox Live and other online gaming services.
TeliaSonera chief Johan Dennelind told ZDNet that the ISP had not “seen an attack on that type of scale before”.
This article was updated at 7.40am PT to change “a few thousand customers” to “thousands of customers” — a correction made at Telia’s request, which may indicate that there were more than a few thousand victims.
The attack took down the PSN on Sunday. It may have been the work of the same person who claimed there was a bomb on a flight carrying a Sony executive, causing the flight to be diverted.
Evernote’s denial of service attack seems to have been going on for at least 10 hours, causing data synchronization problems for users. Feedly’s seems to be connected with an extortion attempt.
The Elance denial-of-service attack has been going on for over a day now, though it is now only sporadic. Elance says it has bought in new defences to try cope. Meanwhile oDesk says it got hit by a briefer, separate attack.
At peak traffic of 300Gbps, the Spamhaus attack is probably unprecedented. But has it really had as big an effect as is suggested in some reports? Here’s what’s going on.
It’s Friday and we know what that means boys and girls. Time for another look at the week in Mobile Tech Manor. This is one of those weeks when I can’t believe it’s almost over already. This week I went from four phone carriers to two.
Heavy users of Microsoft’s OneNote have been left out in the cold unless they also use a Windows Mobile phone. That’s no longer the case due to MobileNoter, an iPhone app that syncs OneNote notebooks on a PC with the iPhone for reference on the run.
Updated: Wow…apparently Twitter has been down for nearly two hours this morning. I was wondering why my Tweetdeck had gone silent for so long. I guess not many people were tweeting. Apparently there is a big denial-of-service attack on Twitter. On the company blog, Twitter co-founder Biz Stone says the company is trying hard to defend against this attack.

AT&T (s t) has finally issued a statement about the company’s unannounced blocking of certain parts of forum site 4Chan. A number of parties blamed AT&T for “censoring” the Internet, presuming that the company had blocked access because of the content on 4Chan, which can range from classless to tasteless to everything in between. In fact, AT&T said it blocked one section of the site to control a distributed-denial-of-service attack that was affecting an unnamed AT&T customer.
