Red Hat has become aware of an active ransomware threat affecting unpatched or unsecured servers running JBoss Application Server and products based on it. The attack utilizeshttps://github.com/joaomatosf/jexbossJexBoss to find vulnerable JBoss systems. These attacks have leveraged out-of-date, and unsecured systems to pivot attacks to other systems on the network.
The ransomware attack affects users of JBoss Application Server who have not correctly secured their JMX consoles as well as users of older, unpatched versions of JBoss enterprise products. An update to JBoss enterprise products was produced in April 2010 to correct the flaw, CVE-2010-0738
Instructions for securing the JMX console are available here: http://community.jboss.org/wiki/SecureTheJmxConsole.
