Yeah, I'm not certain what it means about the fees being later maliciously adjusted.
Seems strange.
Does it mean.
A. If you had 10 bitcoins in your wallet someone could charge the entire 10btc in fees
Even though only want to send 0.01btc to the recipient and want to spend 0.0002 in fees.
I have never heard of such an attack or read about someone suffering from it. I remember seeing mentions of maliciously altered fees, but that's all. I don't know how it's possible to modify a transaction that was already signed by a private key that only you have access to. Wouldn't such a modification require access to the signing keys because it's different transaction data @nc50lc? In that case, you would need to ask yourself who has got your private keys?
