Geth does not ship with RPC support. By default Geth enables modules
["net", "web3", "eth", "shh"]. In case the RPC get compromised, what kind of bad things could happens?
Money lost will definitely be the first place
Assuming you have a wallet managed by Geth, people can freely sent any balance inside away.
Apart from money lost, is there any other things that may potential happens?
For example, if I just run the node as a block tracker and monitor if any money sent into my address. Does RPC has the ability to affect them as well?
