The popular SSH client program PuTTY has released the latest version of its software that includes security patches for 8 high-severity security vulnerabilities. PuTTY is one of the most popular and widely used open-source client-side programs that allows users to remotely access computers over SSH, Telnet, and Rlogin network protocols. Almost 20 months after releasing the last version of its software, the developers of PuTTY earlier this week released the latest version 0.71 for Windows and Unix operating systems. According to an advisory available on its website, all previous versions of the PuTTY software have been found vulnerable to multiple security vulnerabilities that could allow a malicious server or a compromised server to hijack client's system in different ways. Here below I have listed all 8 vulnerabilities with brief information that PuTTY 0.71 has patched: 1) Authentication Prompt Spoofing — Since PuTTY doesn't have a way to indicate whether a piec...

WikiLeaks has today published the 15th batch of its ongoing Vault 7 leak , this time detailing two alleged CIA implants that allowed the agency to intercept and exfiltrate SSH (Secure Shell) credentials from targeted Windows and Linux operating systems using different attack vectors. Secure Shell or SSH is a cryptographic network protocol used for remote login to machines and servers securely over an unsecured network. Dubbed BothanSpy — implant for Microsoft Windows Xshell client, and Gyrfalcon — targets the OpenSSH client on various distributions of Linux OS, including CentOS, Debian, RHEL (Red Hat), openSUSE and Ubuntu. Both implants steal user credentials for all active SSH sessions and then sends them to a CIA-controlled server. BothanSpy — Implant for Windows OS BothanSpy is installed as a Shellterm 3.x extension on the target machine and only works if Xshell is running on it with active sessions. Xshell is a powerful terminal emulator that supports SSH, SFTP, ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
