> The fact that this key was apparently not stored in an HSM, and that GH employees had access to this private key (allowing them to accidentally push it) means that effectively all communication with GH since the founding of the company has to be considered compromised. I think this suggests we need more information from github. For instance GH employees may not always have had live access to this key, this could have happened as part of an operation that gave temporary access to an employee only recently. Or it could have been stored plaintext on multiple employees' home computers since creation. When was the leaked key created anyway?
