Remember, even one insecure extension can bring down your whole site.

Often times, exploits are specific to a particular version of an extension. That's why it's a good idea to remove the version number from any installed extension. Removing the version number can thwart an attack before it happens.

You can edit your extensions to show only the name by using a tool like Dreamweaver. Perform a global search and replace in the respective extension folder. You can then remove any version numbers from your code.
