CloudFlare outage takes down reported 750,000 sites

• CloudFlare is an online WAF (Web Application Firewall) and CDN
• We have talked about outages they have had in the past, but this one is different
• Sites went down on March 3rd at 09:47 UTC (4:47am EST, 1:47am PST), the sites, DNS and other services all returned a ‘no route to host’ error
• Service was restored at 10:49 – a total of just over an hour
• Unlike some previous outages, this took down all 23 of their data centers
• According to CloudFlare, they originally detected a DDoS attack against one or more customers’ DNS servers, and moved to filter that attack
• Their attack profiling software reported that the attack packets were between 99,971 and 99,985 bytes
• This is actually impossible, largest possible IP (Layer 3) packet is 65535 bytes, due to the size of the field that holds the length of the packet in the header (16 bits)
• Also, most layer 2 protocols (like Ethernet) also impose a smaller frame size, the default for Ethernet is 1500 bytes. The CloudFlare network is configured to use ‘jumbo frames’ with a maximum packet size of 4470 bytes
• When they used the Juniper Flowspec protocol to push a rule to all of their routers to block packets of the impossible size, the routers accepted the rules, but then started exhausting all of their ram, probably due to a bug related to the fact that the rule was invalid
• This caused many of the routers to reboot, but then they would load the same rules and just reboot again, in a continuous loop
• Some of the routers also stopped responding on their management interfaces, requiring that the devices be manually power cycled (in the 23 different data centers in 14 countries)
• When the routers were down, the routes would be withdrawn/expired, and it ended up that there were no routes left to allow anyone to reach the CloudFlare network
• CloudFlare is working with Juniper to see if this is a bug in Flowspec, or if it was specific to the rules and traffic of CloudFlare
• CloudFlare is also attempting to find a way to be able to use flowspec to push rules only to a specific subset of their routers (those under attack, or those in a specific region), so that next time it doesn’t take down their entire network at once

Malware doesn’t have to be advanced to be effective

• Researchers have discovered a malware attack that has been ongoing for 10 years using off-the-shelf remote administration software TeamViewer along with proprietary malware
• The attackers managed to exfiltrate encryption keys and ‘secret’ documents from a number of sensitive places, including an unidentified NATO/EU member country’s embassy and an industrial manufacturer in Russia, multiple research and educational institutions in France and Belgium, and a high-profile Hungarian governmental victim
• Kaspersky’s research indicated the threat actors were most likely Russian, because the malware scripts changed the character set to CP1251 and used the Russian localized version of TimeViewer. They also found some possible links to the Red October malware

BBC twitter accounts hacked by Pro-Assad Syrians

• The twitter accounts for BBC Weather, BBC Arabic and BBC Ulster Radio were compromised and posted unauthorized tweets
• “The attacks began in the early afternoon on Thursday. At the same time, BBC staff were alerted to a phishing email that had been sent to some BBC email accounts. It is not yet clear if the two are related”
• The attack was apparently the work of the “Syrian Electronic Army”, a group that has previously shown strong support for Syrian President Bashar-al-Assad
• Humorous tweets were posted, such as:
  • “Saudi weather station down due to head-on collision with camel.”
  • “Chaotic weather forecast for Lebanon as the government decides to distance itself from the Milky Way.”
• The accounts are now back under the control of the BBC
• It is not clear how the accounts were compromised

Google Docs has some powerful features, collaborative editing being chief among them. This week we’ll show you why Etherpad Lite is more than just multiplayer notepad.

Plus why Valve’s Gabe Newell thinks Apple might be a big threat, the major new feature landing in Ubuntu 13.04, and the tasty gift Google gave to some UK schools!

The Open Google Docs Replacement:




Brought to you by: System76

Up front: This is really focused on Google Docs’ collaborative features. As I have found these to be particularly a powerful competitive advantage of Google Docs. If you haven’t tried it, try it during your next meeting, or brainstorming session, or maybe just grocery shop list making from separate rooms. TRY IT!

First launched in November 2008, the software was acquired by Google in December 2009 and released as open source later that month. Several services now use the Etherpad software, including PiratePad, Telecomix Pad, Framapad, Mozilla Pad (MoPad), PrimaryPad, TypeWith.me, Sync.in, TitanPad and iEtherPad.com. Further development is coordinated by the Etherpad Foundation.

Etherpad Lite is an almost complete rewrite of the original Etherpad software, based on different technical foundations and written by different authors. While the original Etherpad is written in Scala and has quite big system requirements, Etherpad Lite is written in server-side JavaScript using node.js. The original realtime synchronization library (called Easysync) remains the same.

Apache License version 2.0 on December 17, 2009.
