JVerify is a Java application that enables you to monitor for changes to any file on your Unix system, but most notably executable binaries, thus alerting you to a possibly backdoored binary. The minimum requirements are JDK1.5.

A new configuration file option was added (runmode) which when selected, will store the binary itself in the database when the application first populates the database. If a binary is infected and the appplicaton is running in "replace" runmode, it will replace the infected binary with the (assumed) clean copy from the database, as well as send notification via email.
A new commandline option was added (-refresh) which allows the user to update the database sums of any binaries that were changed/updated on the system.
