No I am the true Runescape noob here. I didn't have 2FA, nor did i have a bank pin. No gold generators, or programs other than Runelite, WoW and Valorant. I also thought in my head like maybe somehow it dropped my gear. But the set i had on during this was the Graceful set. When i got back to my bank only my gear sets were taken, and the cash stack. I have now updated all that good stuff, and reset all my passwords.
Go to

There is NO way RuneMate would hack you for your gold/items. We would not risk our entire reputation over the small amount of gold/items any user would have.
Furthermore, from the moment you enter your username/password combination in to the client, the information is immediately encrypted and impossible for anyone to read and use.
Bot Authors do not have access to your username or password. The only person who does is YOU.
There have been many accusations of this over the years and almost every single time without fail the user has later determined the fault occurred elsewhere.
Individual bots do not have access to credentials of any sort. In addition, every line of every version of every bot is reviewed by a proprietary scanner for malicious code
and manually by a Staff member.
Regarding your computer, I suggest running a scan using Windows Defender and Malware Bytes and taking any recommended actions.
To summarise and make it extremely clear, RuneMate did not hack you and steal your items.
