Judging by the fact that the cryptocurrency was stolen from two different wallets, it means that it is not a matter of cracking the secret keys to these wallets. An attacker has entered your device's desktop. This often happens when a goodle account is hacked or a special virus has entered the device that sends data from your device. Secret keys should not be stored on the device. The wallet login must have a password, which also must not be on the device.
