Can you give me a few hints on what to look for on the topic?
Bitcoin itself? Not at all. The blockchain has never been hacked, exploited or abused in any way. Centralized entities that own Bitcoin like regular users, centralized cryptocurrency exchanges on the other hand, yes, those points are vulnerable to security threats.
Do some research on the wallet software you plan to use. Has it been vetted by the Bitcointalk community? Is it open source? Is it non-custodial?
Devices that contain important data pertaining to your wallet (like your seed phrase, for example) should be disconnected from the internet and other devices. Don't share your seed phrase and don't connect your wallet to anything fishy. Be wary of strange currencies or strange transactions. When in doubt, best get a new wallet and transfer the coin to the new wallet.
