Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The pitfalls of using SSH-agent, or how to use an agent safely
For Mac users, there is this: https://github.com/TimidRobot/mac-ssh-confirm
Doesn't add 2FA so much as it prompts you for each agent use.
On the remote end, you can enable 2FA for logging into the server with libpam-google-authenticator.

Terrapin Attack for prefix injection in SSH
Unless I'm misunderstanding what this is about RFC5647 merely points out that the sequence number is included as AAD due to RFC4253 requirements. The [email protected] specification is not exactly the most rigorous thing I've ever seen (https://github.com/openssh/openssh-portable/blob/master/PROT...) but reading it, the sequence number is only included in the IV, and not as AAD, which directly runs afoul of the RFC4253 section 6.4 requirement for it to be included in the MAC.

SSH keys stolen by stream of malicious PyPI and NPM packages
The key layout is described in https://github.com/openssh/openssh-portable/blob/master/PROT... and you can view it pretty easily via
cat private_key_here | head -n -1 | tail -n +2 | base64 -d | xxd
One I created in 2016 is using aes256-cbc with bcrypt for the kdf, which isn't awful at all.

Microsoft signing keys were leaked
Interestingly, it looks like ssh-agent disables core dumps[1], but I don't see similar usage for sshd

An Excruciatingly Detailed Guide to SSH (But Only the Things I Find Useful)
There's a current pull request for adding AF_UNIX support, which should make all kinds of exciting forwarding possible, since it will make it easy to proxy ssh connections through an arbitrary local process which can do anything to forward the data to the remote end.

Funds of every Trust Wallet browser extension could have been stolen
It doesn't, at least not for generic/unmodified cryptographic applications.
WebAuthN signatures are of a very specific challenge/response format that applications need to explicitly support. For example, SSH had to add new key and signature formats [1] to support it.
Theoretically, a blockchain/cryptocurrency application could adopt the WebAuthN signature format as its canonical or an alternative signature format, but I'm not aware of any popular one having done so.

We updated our RSA SSH host key
I just tested it and looked at the code briefly; the client fortunately does seem to remove all keys not provided by the server: https://github.com/openssh/openssh-portable/blob/36c6c3eff5e...
It seems like at least a `known_hosts` compromise would be "self-healing" after connecting to the legitimate github.com server once.
