My ETH funds were stolen and I am sure I didn't give out or handled carelessly the Mnemonic phrase, JSON file, private key nor the key store. Please I want to know ways by which a cryptocurrency wallet could be hacked.
This maybe because you are wrong entered a private key on a phishing website, Go clear your cookies and bookmark the real one (myetherwallet.com - remember it's with "com", other than this is obviously phising)
