There is a piece of bad news for anyone using Hadoop for data analytics. According to Radware Research team (25 Oct 2018), they have found a new botnet out targeting Hadoop clusters seeking to perform DDoS attacks.
(NOTE: Hadoop, which is an open source distributed processing framework, allows for the distributed processing of massive amounts of data and computation across clusters of computers using simple programming models).
Security teams should also look to invest in mitigation tools and services that specialize in defending against a DDoS attack. Also, it is important to consider whether the Hadoop is necessary to connect to the Internet to reduce the chance of exposure for attack.
