The important factor that should be noted here is RAT will be a threat to Bitcointalk forum also. It scans for few websites in the browser history where "bitcointalk.org" is one among them.
In the crypto category, it scans "coindesk.com", "coinbase.com", "binance.com" etc.
Actually, if it is a RAT, you are in trouble anyway.
A RAT (
Remote
Administration
Tool) gives the attacker full access (under installed permissions) to your system.
It doesn't really matter what it is searching for upon infection.
An attacker can always simply download additional payload onto your system to do additional stuff (e.g. looking for wallet files, passwords, mnemonic codes in text files, etc..).
The point is.. if you are infected with a RAT-like kind of malware, your system is owned by the attacker. And he can do whatever he wishes.
So, any RAT is extremely dangerous. The one you mentioned would not be different at all.
