RegreSSHion is a family of security bugs in the OpenSSH software that allows for an attacker to remotely execute code and gain potential root access on a machine running the OpenSSH Server. [1] [2] The vulnerability was discovered by the Qualys Threat Research Unit and was disclosed on July 1, 2024.
The malicious code is known to be in 5.6.0 and 5.6.1 releases of the XZ Utils software package. The exploit remains dormant unless a specific third-party patch of the SSH server is used. Under the right circumstances this interference could potentially enable a malicious actor to break sshd authentication and gain unauthorized access to the ...
Shellshock is an arbitrary code execution vulnerability that offers a way for users of a system to execute commands that should be unavailable to them. This happens through Bash's "function export" feature, whereby one Bash process can share command scripts with other Bash processes that it executes. [ 17 ]
This allows the vulnerability scanner to access low-level data, such as specific services and configuration details of the host operating system. It's then able to provide detailed and accurate information about the operating system and installed software, including configuration issues and missing security patches.
The researchers who discovered the attack have also created a vulnerability scanner to determine whether an SSH server or client is vulnerable. [8] The attack has been given the CVE ID CVE-2023-48795. [9] [3] In addition to the main attack, two other vulnerabilities were found in AsyncSSH, and assigned the CVE IDs CVE-2023-46445 and CVE-2023 ...

Security Administrator Tool for Analyzing Networks (SATAN) was a free software vulnerability scanner for analyzing networked computers.SATAN captured the attention of a broad technical audience, appearing in PC Magazine [1] and drawing threats from the United States Department of Justice. [1]
Doug Rickert has experimented with the open-source Cowrie SSH honeypot and wrote about it on Medium. Putting up a simple honeypot isn't difficult, and there are many open-source products besides Cowrie, including the original Honeyd to MongoDB and NoSQL honeypots, to ones that emulate web servers.
