New DemonBot Discovered
Are you using Hadoop for data analytics? If so, know that a new bot is targeting Hadoop clusters with the intention of performing DDoS attacks powered by the strength of cloud infrastructure servers. Hadoop is an open source distributed processing framework that manages storage and data processing for big data applications running in clustered systems.
Radware Threat Research Center is monitoring and tracking a malicious agent that is leveraging a Hadoop YARN unauthenticated remote command execution in order to infect Hadoop clusters with an unsophisticated new bot that identifies itself as DemonBot.
DemonBot spreads only via central servers and does not expose worm-like behavior exhibited by Mirai based bots. As of today, Radware is tracking over 70 active exploit servers that are actively spreading DemonBot and are exploiting servers at an aggregated rate of over 1 Million exploits per day. Note that though we did not find any evidence that DemonBot is actively targeting IoT devices at this time, Demonbot is not limited to x86 Hadoop servers and is binary compatible with most known IoT devices, following the Mirai build principles.
It is not the first time that cloud infrastructure servers have been targeted. Earlier this month Security Researcher Ankit Anubhav discovered a hacker leveraging the same Hadoop Yarn bug in a Sora botnet variant. Hadoop clusters typically are very capable and stable platforms and can individually account for much larger volumes of DDoS traffic compared to IoT devices. The DDoS attack vectors supported by DemonBot are UDP and TCP floods.
