Enterprise search engine Elasticsearch is under threat of being turned into a sophisticated cryptocurrency mining botnet to be used in distributed denial of service (DDoS) attacks. Cybersecurity firm Trend Micro describes a new malware strain that launches multi-stage attacks on publicly accessible databases and servers that run old versions of Elasticsearch software. “[…] Many of the malicious traffic or attacks that we see targeting Elasticsearch are relatively straightforward, and more often than not, profit-driven,” wrote Trend Micro.
