GitHub Quickly Replaces Compromised RSA SSH Key to Safeguard Git Operations.
On March 24, 2023, Ravie Lakshmanan wrote a blog post about cloud security and programming.
GitHub, a service that hosts repositories in the cloud, replaced its RSA SSH host key used for securing Git operations as a precautionary measure. This decision was made after the key was briefly exposed in a public repository.
On March 24, 2023 at 05:00 UTC, there was an action taken to stop anyone from impersonating the service or listening in on users' activities over SSH. This was considered a precautionary measure to ensure maximum security.
According to a blog entry by GitHub's Chief Security Officer and Engineering SVP, Mike Hanley, this particular key will not provide entry into customer data or GitHub's infrastructure. Rather, it will only influence Git actions through SSH with the use of RSA.
The motion won't affect the movement of Web traffic to GitHub.com and Git actions carried out through HTTPS. Users of ECDSA or Ed25519 do not need to make any modifications.
According to the company owned by Microsoft, there is no indication that any enemies were able to access the SSH private key that was exposed. The duration for which the secret was exposed was not revealed.
The statement reiterated that the problem did not stem from any security breach of GitHub's systems or client data. Instead, it was attributed to an accidental disclosure of confidential information.
The report additionally stated that individuals who use GitHub Actions might encounter unsuccessful runs for their workflows if they are utilizing actions/checkout with an ssh-key option. It further mentioned that the action is currently being improved for all tags.
