Here's excellent news for sysadmins. You can now use a physical security key as hardware-based two-factor authentication to securely log into a remote system via SSH protocol. OpenSSH, one of the most widely used open-source implementations of the Secure Shell (SSH) Protocol, yesterday announced the 8.2 version of the software that primarily includes two new significant security enhancements. First, OpenSSH 8.2 added support for FIDO/U2F hardware authenticators , and the second, it has deprecated SSH-RSA public key signature algorithm and planned to disable it by default in the future versions of the software. FIDO (Fast Identity Online) protocol based hardware security devices are stronger and fool-proof mechanisms for authentication because it enables public-key cryptography to protect against advanced malware, phishing, and man-in-the-middle attacks. "In OpenSSH, FIDO devices are supported by new public key types' ecdsa-sk' and 'ed25519-sk', along

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

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

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,

Are millions of enterprise users, who rely on the next-generation firewalls for protection, actually protected from hackers? Probably Not. Just less than a month after an unauthorized backdoor found in Juniper Networks firewalls, an anonymous security researcher has discovered highly suspicious code in FortiOS firewalls from enterprise security vendor Fortinet. According to the leaked information, FortiOS operating system, deployed on Fortinet's FortiGate firewall networking equipment, includes an SSH backdoor that can be used to access its firewall equipment. Anyone can Access FortiOS SSH Backdoor Anyone with " Fortimanager_Access " username and a hashed version of the " FGTAbc11*xy+Qqz27 " password string, which is hard coded into the firewall, can login into Fortinet's FortiGate firewall networking equipment. However, according to the company's product details, this SSH user is created for challenge-and-response authenti

A simple but highly critical vulnerability recently disclosed in the most widely used OpenSSH software allows attackers to try thousands of password login attempts per connection in a short period. OpenSSH is the most popular software widely used for secure remote access to Linux-based systems. Generally, the software allows 3 to 6 Password login attempts before closing a connection, but a new vulnerability lets attackers perform thousands of authentication requests remotely . OpenSSH servers with keyboard-interactive authentication enabled , including FreeBSD Linux, can be exploited to carry out the brute force attack on OpenSSH protocol, a security researcher with online alias KingCope explained in a blog post . Exploit for the Vulnerability RELEASED  Hackers could widely exploit the vulnerability because the keyboard-interactive authentication is by default enabled on most of the systems. Researcher has also released a proof-of-concept exploit code, which i
