A few CIBC bank phishing sites are also live at the time of this writing.Ī notable technical aspect of this botnet is its use of SSL certificates for securing traffic.In the past months, this proxy network delivered Teslacrypt payments sites, RockLoader, Quakbot and Ramdo C2 domains, as well as phishing, and carding sites.Ĭurrently, the longest living active domains served by the botnet are carding sites such as: A subset of the entire botnet support this reverse proxy feature. The content of hxxp:/// can be delivered by any bot IP supporting this feature. hxxp:/// is a known carding site that is currently served by the fast flux infrastructure. The network performs reverse proxy functions similar to that of a common CDN, but with an emphasis on hiding the upstream malware content providers.įor example, curl –header ‘Host: ’ hxxp://109.86.110.190 will return the main page of hxxp:/// where 109.86.110.190 is a live bot IP. Content Delivery Network functionalityĪt the moment, this network is leveraging up to 56,000 live bots that consist in compromised home and SOHO routers concentrated in Russia and Ukraine.

We also collaborated with Intel471 to shed light on the underground service and actors behind this botnet. This year at Black Hat 2016, we will be unveiling novel results about this bulletproof fast flux hosting infrastructure. More recently, a few blogs in 2016 touched upon this botnet such as. Even the ephemeral new GameOver Zeus used it to host some of its DGAs in July 2014 before it switched to dedicated hosting then withered away. At the time, the network has added more malware variants served on behalf of its clientele such as Zemot/Rerdom, Necurs, Tinba, and Rovnix.
#Flux hacked client setting keys update#
We discussed the new TTL update at 2015. This infrastructure evolved most likely to evade detection or for other operational reasons.

The botnet also started supporting SSL communication. In Mid 2015, the operators behind the “Zbot” proxy network updated their setup in such a way that the served fast flux domains were now resolving to bot IPs with a random TTL in the range between 129 to 150 seconds and the network remained double flux. We subsequently presented more results about this botnet at Botconf 2014.

At the time, the botnet was used by criminal customers to serve Zeus, Kins, ICE IX and Citadel config, binary and drop zone urls in addition to Asprox and DDoS bot C2s, phishing sites and Pony panels. The name servers of these domains were also fluxing to IPs from the botnet which characterizes this network as double flux. It was easy to recognize because the domains it was hosting had a TTL value of 150 seconds. This hosting network is a botnet that consisted of a couple tens of thousands of infected hosts located mainly in Russia and Ukraine. At Botconf 2013, this proxy network was briefly mentioned and dubbed “fluxxy” by Nick Summerlin and Brad Porter. Īt Black Hat 2014 and Defcon 22, we disclosed research about another fast flux hosting infrastructure we called the “Zbot fast flux proxy network” which we have been tracking since 2013. We covered the Kelihos fast flux network back in 2013 in a few blogs as well as at BSides New Orleans, APWG eCrime, and Botconf. They represent a hosting-as-a-service or reverse proxy platform for various malware and ransomware C2 domains, as well as phishing and carding sites. In the current cybercrime ecosystem, fast flux proxy networks are an efficient form of bulletproof hosting.
