Targeted Cryptocurrency Applications represent a mixture of closed and open source wallets, which means that the target is not cryptocurrency wallets, but the operating system.
When they successfully infect your computer, they can collect many types of data and can analyze data they steal from your devices to do further steps. Like stealing your online accounts, your exchange accounts or accessing your cryptocurrency wallets and moving your coins and tokens.
They can do it instantly with your compromised cryptocurrency wallets or they can simply note it down, add it to their real time tracker tools and wait till a day your wallets have a big IN transaction then they will steal that big amount.
Your use of the Linux operating system will reduce these risks a lot.Do not install applications from unknown sources, random clicking on links and similar tips are still good solutions for such viruses, but I think that antivirus services prepare such lists of wallets to give fragmented solutions and thus higher returns for them.
Linux is less targeted by hackers than Windows and it is better to use if you are using cryptocurrency wallet.
