2023-11-27 13:18

A new study has demonstrated that it's possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational...

Researchers extract RSA keys from SSH server signing errors
2023-11-19 15:01

A team of academic researchers from universities in California and Massachusetts demonstrated that it's possible under certain conditions for passive network attackers to retrieve secret RSA keys from naturally occurring errors leading to failed SSH connection attempts. A paper published by university researchers Keegan Ryan, Kaiwen He, Nadia Heninger, and George Arnold Sullivan, shows that it's possible for a passive network attacker to obtain a private RSA key from SSH servers experiencing faults during signature computation.

New SSH Vulnerability
2023-11-15 17:51

For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally occurring computational errors occur while the connection is being established. The vulnerability occurs when there are errors during the signature generation that takes place when a client and server are establishing a connection.

How to Mount Remote Directories with SSH (+Video Tutorial)
2023-10-11 10:05

How to Mount Remote Directories with SSH Learn how to easily mount remote directories with the help of a more secure SSH tool. Do you have remote directories you need to mount on your local desktop so you can work on code, configurations, documentation or just about any kind of file? If those remote files are on a server and you don't want to share them via the less secure Samba, Secure Shell has you covered.

SSH keys stolen by stream of malicious PyPI and npm packages
2023-09-27 21:48

A stream of malicious npm and PyPi packages have been found stealing a wide range of sensitive data from software developers on the platforms. The campaign started on September 12, 2023, and was first discovered by Sonatype, whose analysts unearthed 14 malicious packages on npm.

How to Compare the Contents of Local & Remote Files With the Help of SSH
2023-09-25 19:05

Have you ever needed to compare the contents of a local and remote file without having to copy the remote file to the local machine and then run the diff command on both? Sure, it's not exactly a challenging task, but it's not exactly the most efficient way to compare those files. Let's say you have a file named test on both local and remote machines, and you want to compare the contents.
