Cracking the Code: Could SSH Server Connections Be Vulnerable?
RSA Host Keys Plundered
• A recent study has highlighted the possibility for passive network attackers to access private RSA host keys.
• This vulnerability arises during the establishment of a connection to an SSH server, when naturally occurring computational faults occur.
Paraphrasing these main points, “RAIDing” the SSH servers might be more efficient than CoD fans think, with researchers demonstrating that the embedded RSA host keys are ripe for the picking. So, at the end of the day, you can’t have security without ‘SSH’ — but can you still have ‘SSH’ without security?
The Secure Shell Protocol
• The Secure Shell (SSH) protocol is a secure way of transmitting commands and logins over unsecured networks.
This might make you think of a tech turtle, secure and slow inside its shell, or maybe your teenage kids hiding out in their rooms when you want to talk about network security. Well, that’s basically what the SSH protocol does. It prowls unsecured networks like your teen to his reported homework, hoping that no prying eyes will catch sight of what they’re intending to transmit.
To summarize all of this tech-talk, it’s like preparing your secret grandma’s cookie recipe in a see-through kitchen. The SSH protocol, your fail-safe oven mitts, may have a weak point that make queuing up for the ‘bake-off’ a risky venture. This potential vulnerability could allow lurking network adversaries to snag those sweet, sweet private RSA host keys right from under your nose. A bit like swiping the last cookie from the cookie jar, don’t you think?
In essence, you might have more guests for tea than you planned for if you’re not careful about securing your SSH server connections.Original Article: https://thehackernews.com/2023/11/experts-uncover-passive-method-to.html
