Was there ever a case have been Bitcoin or Bitcoin-Core itself was compromised? For instance, did it ever occur {that a} malware hacker might insert code that compromised Bitcoin on the protocol stage? For instance, a committer to Bitcoin hypothetically compromises the protocol in order that some transactions are stolen? I see loads of studies that pockets suppliers and cryptoexchanges have been hacked, however little or no about Bitcoin itself has ever been compromised. In a single case, an adversary appears to have compromised the server that hosted the Bitcoin.org web site. However that’s not a compromise of the protocol.
