We start with the most recent case, Poodle, and move on to Shellshock and Heartbleed. A full list of resources for all of these incidents can be found here.
We also look ahead to potential security trends in 2015.
Akamai's Prolexic Security Engineering & Research Team (PLXsert) issued a new advisory Monday that provides a full analysis of the Poodle vulnerability, including actions companies can take to blunt the impact.
It's the latest in a series of postings Akamai has done to keep the public informed of its Poodle response. In addition to reviewing this new advisory, please refer to the following posts as well:
This is the latest in a string of severe vulnerabilities this year, including Shellshock and Heartbleed. A full list of resources for all of these incidents can be found here.
CAMBRIDGE, Mass. - October 23, 2014 - Akamai Technologies, Inc. (NASDAQ: AKAM), the leading provider of cloud services for delivering, optimizing and securing online content and business applications, today announced availability of the Q3 2014 State of the Internet - Security Report. Akamai's Prolexic Security Engineering and Research Team (PLXsert) is a recognized leader in Distributed Denial of Service (DDoS) protection services and strategies. This quarter's report, which provides analysis and insight into the global attack threat landscape including DDoS attacks, can be downloaded at www.stateoftheinternet.com/security-report.
"DDoS attack size and volume have gone through the roof this year," said John Summers, vice president, Security Business Unit at Akamai Technologies. "In the third quarter alone, Akamai mitigated 17 attacks greater than 100 gigabits-per-second, with the largest at 321 Gbps. Interestingly, we witnessed none of that size in the same quarter a year ago and only six last quarter. These mega-attacks each used multiple DDoS vectors to deliver large bandwidth-consuming packets at an extremely high rate of speed."
Today we've launched the first all-security edition of the State of the Internet report. State of the Internet also has its own website now, where readers can delve into Akamai's threat intelligence, threat advisories, data visualizations and more.
Highlights of the security edition for Q3 2014 include a four-fold year-over-year increase in DDoS attack size and volume; new attacks targeting hand-held devices and the proliferation of easy-to-use attack tools.
In the latest episode of the Akamai Security Podcast, I talk to CSIRT Manager Mike Kun about what he calls an "interesting new attack vector" where bad actors forgo direct attacks against websites in favor of targeting third-party services the site is using.
"Rather than go against a target directly, bad actors are looking at what other services that website is using," Kun explains. "A simple one is DNS. If the attacker can compromise the registrar a site is hosted with, they can easily change the IP address mapping and point that at some other site."
Those who go for such attacks include hactivist groups looking to deface sites, or someone looking to steal information or drop malware for myriad purposes.
Widget providers are among the targeted. Kun notes that the chat function now available on many e-commerce sites is usually supplied by third parties.
"Sites are linking to code from third-party sites instead of running local code," Kun says. "So if an attacker can compromise that widget, they can attack your site."

It's been a year of major security vulnerabilities. Last week we worked to mitigate the Poodle vulnerability. Two weeks before that was Shellshock and in April we had Heartbleed. All have shaken the security industry to the core, and Akamai staff have spent countless hours working to protect customers against these threats.
To get a wider perspective of our actions in the face of such incidents, here's a collection of resources -- essentially everything we've had to say about Poodle, Shellshock and Heartbleed.
May you find it useful and insightful.
The Boston Application Security Conference (BASC) was this past weekend, and Patrick Laverty from Akamai InfoSec's CSIRT team gave a talk called "How Hackers View Your Web Site."
Patrick recorded the talk and posted it on his YouTube channel. Like everything he does, it's quite good. So I'm sharing it here.
Laverty described his talk this way:
"As defenders, we have to be right 100% of the time where an attacker only needs to be right once. The attack surface of a modern web site is incredibly large and we need to be aware of all of it. Additionally, individual attacks may not always be effective but sometimes using them together can gain the desired effect. In this talk, we'll take a look at the whole attack surface for a typical web site and the various ways that an attacker will use to compromise a site."
The Poodle attack (CVE-2014-3566) raised many questions from our customers, peers, auditors, and prospects. This post addresses some of the most frequently asked questions, and provides an update on how Akamai is handling its operations during this industry-wide event. For a basic background on Poodle, please read Akamai CSO Andy Ellis's overview blog post, or Akamai Security Researcher Daniel Franke's in-depth analysis.
Attackers are using Universal Plug and Play (UPnP) devices to launch massive DDoS assaults, Akamai's Prolexic Security Engineering & Research Team (PLXsert) warned this morning in an advisory.
PLXsert estimates that 4.1 million UPnP devices are potentially vulnerable to exploits used for reflection DDoS attacks. That's about 38 percent of the 11 million devices in use around the world. PLXsert plans to share the list of potentially exploitable devices to members of the security community in an effort to collaborate with cleanup and mitigation efforts.
