ClientProtection is a Minecraft Forge modification that notifies you when a mod uses a suspected malicious method call. This mod does this when booted up:
Index loaded mods.
Detect mod JARs.
Detect classes inside of the mod JARs.
Scan the classes to see if they call a possibly dangerous method to the client's computer.
ClientProtection will be updated very often to improve it's malicious definitions. In the future, I intend to put a custom XML definition system to make ClientProtection independent from updating malicious definitions.
ClientProtection requires these libraries:
ASM Tree (already included in Minecraft Forge, you do not need to install anything else)
Here is a screenshot of me, testing out the Iron Chest mod:
