A critical vulnerability in Kubernetes could allow unauthorized SSH access to a virtual machine running an image created with the Kubernetes Image Builder project. [...]
Cybersecurity researchers have discovered a new variant of the Gafgyt botnet that's targeting machines with weak SSH passwords to ultimately mine cryptocurrency on compromised instances using their GPU computational power. The infected devices are corralled into a botnet capable of launching distributed denial-of-service attacks against targets of interest.
This tool helps security teams validate SSH implementations by testing for uncommon but dangerous misconfigurations and software bugs. Activities intended to aid in responding to the incident led runZero's research team to discover weaknesses across SSH implementations and applications that impact critical network security devices and software.
Secretive is an open-source, user-friendly app designed to store and manage SSH keys within the Secure Enclave. Typically, SSH keys are stored on disk with appropriate permissions, which is usually sufficient.
SSH-snake is an open-source worm that steals SSH private keys on compromised servers and uses them to move laterally to other servers while dropping additional payloads on breached systems. Previously, Sysdig identified roughly 100 CRYSTALRAY victims impacted by the SSH-Snake attacks and highlighted the network mapping tool's capabilities to steal private keys and facilitate stealthy lateral network movement.
The vulnerability, which is a signal handler race condition in OpenSSH's server, allows unauthenticated remote code execution as root on glibc-based Linux systems; that presents a significant security risk. This vulnerability, if exploited, could lead to full system compromise where an attacker can execute arbitrary code with the highest privileges, resulting in a complete system takeover, installation of malware, data manipulation, and the creation of backdoors for persistent access.
Citrix notified customers this week to manually mitigate a PuTTY SSH client vulnerability that could allow attackers to steal a XenCenter admin's private SSH key. The security flaw impacts multiple versions of XenCenter for Citrix Hypervisor 8.2 CU1 LTSR, which bundle and use PuTTY to make SSH connections from XenCenter to guest VMs when clicking the "Open SSH Console" button.
Cisco is warning about a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH...
A vulnerability tracked as CVE-2024-31497 in PuTTY 0.68 through 0.80 could potentially allow attackers with access to 60 cryptographic signatures to recover the private key used for their generation. PuTTY is a popular open-source terminal emulator, serial console, and network file transfer application that supports SSH, Telnet, SCP, and SFTP. System administrators and developers predominantly use the software to remotely access and manage servers and other networked devices over SSH from a Windows-based client.
