Unlike recent variants of Mirai and Gafgyt that target vulnerable Linux systems via randomly generated IP addresses, Xbash also scans and trawls through domain names. The C&amp;C scans for specific destinations’ known vulnerabilities in Hadoop, Redis and ActiveMQ (CVE-2016-3088) for self-propagation. Hadoop’s unauthenticated command execution flaw discovered in October 2016, as well as the Redis arbitrary and remote command execution vulnerability disclosed in October 2015, have yet to be assigned CVE numbers. Based on the active C&amp;C traffic, it scans and probes for open TCP or UDP ports such as HTTP, VNC, MySQL/MariaDB, Telnet, FTP, MongoDB, RDP, ElasticSearch, Oracle Database, CouchDB, Rlogin and PostgreSQL. While the malware uses a weak username and password dictionary to brute force itself into the service, it is also able to update its set from the C&amp;C server, delete all the databases, and display the ransom message
