Cloud-based repository hosting service GitHub said it took the step of replacing its RSA SSH host key used to secure Git operations "Out of an abundance of caution" after it was briefly exposed in a public repository. The activity, which was carried out at 05:00 UTC on March 24, 2023, is said to have been undertaken as a measure to prevent any bad actor from impersonating the service or eavesdropping on users' operations over SSH. "This key does not grant access to GitHub's infrastructure or customer data," Mike Hanley, chief security officer and SVP of engineering at GitHub, said in a post.
Recently, Chinese researchers have claimed that an existing algorithm can be used with today's quantum computers to break the RSA algorithm, which is the fundamental basis of secure internet communication. The basic claim of the paper, published last Christmas by 24 Chinese researchers, is that they have found an algorithm that enables 2,048-bit RSA keys to be broken even with the relatively low-power quantum computers available today.
Without meeting up first to agree on a secret encryption key. Very simply put, RSA has not one key, like a traditional door lock, but two different keys, one for locking the door and the other for unlocking it.
We have long known from Shor's algorithm that factoring with a quantum computer is easy. What the researchers have done is combine classical lattice reduction factoring techniques with a quantum approximate optimization algorithm.

Tracked as CVE-2022-20866, this security flaw is due to a weakness in handling RSA keys on ASA and FTD devices. If successfully exploited, it can let unauthenticated attackers retrieve an RSA private key remotely, which they can use to decrypt the device traffic or impersonate Cisco ASA/FTD devices.
