By Akamai SIRT Two quarters ago, we introduced Sankey diagrams to the State of the Internet: Security Report. Sankey graphs help visualize energy, material, or cost transfers between processes. The Sankey graph below shows how DDoS reflection attacks have trended during the past five quarters. We tracked ten infrastructure-layer DDoS-reflection vectors. The most used vectors seem to correlate with the number of Internet devices that use these specific service protocols
Akamai SIRT is investigating a new DDoS reflection and amplification method that abuses TFTP. This is yet another UDP-based protocol that has been added to the list of DDoS amplification scripts available for malicious use.

By Mike Kun, Manager, Akamai SIRT Extortion attacks have risen since DD4BC kicked things off last year. DD4BC peaked in July and the Armada Collective took over after that, sending out emails threatening attacks unless the victim(s) made ransom payments in bitcoins. The most recent round involved many ransom demand letters, but, as far as many observers can tell, very little follow through. Now we have Lizard Squad, or at
Akamai Security Researcher Or Katz was recently published at InfoSecurity talking about how to defend against web application account takeovers with cloud security intelligence.
One of the most common complaints on the Akamai Community is from people who are browsing the web from IP addresses that Akamai has seen performing malicious activity. Depending on the severity and number of these malicious activities, Akamai assigns the IP address a rating that predicts the likelihood that the IP will perform a malicious act in the future. These ratings come from our Client Reputation module, a module
