Introduction In the dynamic landscape of cybersecurity, vigilance is critical. A recent study has highlighted a vulnerability known as “Passive SSH Key Compromise,” which poses risks to SSH connections through certain RSA key signature generation flaws. At Jadaptive, we prioritize your security and have conducted a comprehensive analysis of our products in light of this […]
Introduction Secure Shell (SSH) is an essential protocol for secure communication over unsecured networks. Developed in the 1990s, and designed as a replacement for insecure remote shell protocols like telnet and rsh, providing encrypted channel communication and strong authentication. With two iterations, SSH-1 and SSH-2, SSH-2 is the most widely used version today due to […]
After upgrading your OpenSSH client or your OS distribution, you may encounter this error when connecting to your SSH servers. What does “no matching host key type found” mean? When establishing an SSH connection, the client uses the host key of the SSH server to verify the information the server has provided, which it does […]
In 2019, I answered a question on StackOverflow on converting an OpenSSH Private Key to an RSA Private Key. Recently, I had an inquiry about this, so I thought it would be helpful to document for others the exact steps required to perform the conversion in Java using the Maverick Synergy Java SSH API. https://stackoverflow.com/questions/56900615/how-to-convert-openssh-private-key-to-rsa-private-key-in-java […]
I put together this simple application to demonstrate the Log4Shell vulnerability to my colleagues. To exploit the vulnerability, we need an exploit string and a Java Main class that logs that string using Log4J. First, we need to set up the application. The easiest way is through Maven to set up the Log4J dependency. I’m […]
