SSH protects the world’s most sensitive networks. It just got a lot weaker | ArsTechnica (arstechnica.com)

"The Terrapin attack is a novel cryptographic attack targeting the integrity of the SSH protocol, the first-ever practical attack of its kind, and one of the very few attacks against SSH at all. The attack exploits weaknesses in the specification of SSH paired with widespread algorithms, namely ChaCha20-Poly1305 and CBC-EtM, to remove an arbitrary number of protected messages at the beginning of the secure channel, thus breaking integrity. In practice, the attack can be used to impede the negotiation of certain security-relevant protocol extensions. Moreover, Terrapin enables more advanced exploitation techniques when combined with particular implementation flaws, leading to a total loss of confidentiality and integrity in the worst case."

“Although we suggest backward-compatible countermeasures to stop our attacks, we note that the security of the SSH protocol would benefit from a redesign from scratch, guided by all findings and insights from both practical and theoretical security analysis, in a similar manner as was done for TLS 1.3.”

Eh, I briefly checked through their comment history (I almost never do that), and I didn't see any kind of trend here. I think they're just having a weird day and thought it would be funny. It's not, it's just annoying, but they don't seem like a toxic person in general.

That said, you giving a grammar lesson gave me a chuckle.

Women dressing like that for cooking wants viewers badly. :)

You want to be treated like a man (if you are a girl)?

I don’t understand why people are surprised there are gender differences. It’s supposed to be. And we are supposed to react to eachother, be different to eachother. It’s natural biologically and physically and this is completely obvious.

You think women don’t explain to men how something works a million times a day? I hear it so often I can’t even count. It’s perfectly natural.

@1984@lemmy.today on mansplaining.

Are they a full-out christofascist out to kill all queers? I highly doubt it. Are they stuck in a rigid, binary, essentialist definition of gender, to the detriment of themselves and any woman or queer person who crosses their path? Yeah, definitely. However, to be fair that's like 80% of cishet guys (which I think we can safely assume is how they identify) so I may have been quick on the harshness in my original comment. Still deserves to be called out, though.

I also just noticed they edited their comment since my reply, it did not say "let's rename it for fun", it used to be something along the lines of "rename it before getting cancelled".
