A Framework for Enhanced Security: Continuous Threat Exposure Management (CTEM)

A Framework for Enhanced Security: Continuous Threat Exposure Management (CTEM)

May 29, 2023 Cloud Security / Exposure Management
If you're a cybersecurity professional, you're likely familiar with the sea of acronyms our industry is obsessed with. From CNAPP, to CWPP, to CIEM and all of the myriad others, there seems to be a new initialism born each day. In this article, we'll look at another trending acronym – CTEM, which stands for Continuous Threat Exposure Management – and the often-surprising challenges that come along with seeing a CTEM program through to maturity. While the concept of CTEM isn't brand spanking new, having made its in-print debut in July of 2022, we are now at the point where many organizations are starting to try to operationalize the programs that they've been setting into motion over the last few months. And as organizations start to execute their carefully designed plans, they may find themselves bumping up against some unexpected challenges which can lead to setbacks.  What is Continuous Threat Exposure Management (CTEM)? But first, to backtrack, let's just

Critical OAuth Vulnerability in Expo Framework Allows Account Hijacking

May 27, 2023 API Security / Vulnerability
A critical security vulnerability has been disclosed in the Open Authorization (OAuth) implementation of the application development framework Expo.io. The shortcoming, assigned the CVE identifier  CVE-2023-28131 , has a severity rating of 9.6 on the CVSS scoring system. API security firm Salt Labs  said  the issue rendered services using the framework susceptible to credential leakage, which could then be used to hijack accounts and siphon sensitive data. Under certain circumstances, a threat actor could have taken advantage of the flaw to perform arbitrary actions on behalf of a compromised user on various platforms such as Facebook, Google, or Twitter. Expo, similar to Electron, is an open source platform for developing universal native apps that run on Android, iOS, and the web. It's worth noting that for the attack to be successful, sites and applications using Expo should have configured the AuthSession Proxy setting for single sign-on (SSO) using a third-party provider
Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Barracuda Warns of Zero-Day Exploited to Breach Email Security Gateway Appliances

May 26, 2023 Email Security / Zero-Day
Email protection and network security services provider Barracuda is warning users about a zero-day flaw that it said has been exploited to breach the company's Email Security Gateway (ESG) appliances. The zero-day is being tracked as  CVE-2023-2868  and has been described as a remote code injection vulnerability affecting versions 5.1.3.001 through 9.2.0.006. The California-headquartered firm  said  the issue is rooted in a component that screens the attachments of incoming emails. "The vulnerability arises out of a failure to comprehensively sanitize the processing of .tar file (tape archives)," according to an  advisory  from the NIST's national vulnerability database. "The vulnerability stems from incomplete input validation of a user-supplied .tar file as it pertains to the names of the files contained within the archive. As a consequence, a remote attacker can specifically format these file names in a particular manner that will result in remotely exe

Zyxel Issues Critical Security Patches for Firewall and VPN Products

Zyxel Issues Critical Security Patches for Firewall and VPN Products

May 25, 2023 Network Security / Vulnerability
Zyxel has released software updates to address two critical security flaws affecting select firewall and VPN products that could be abused by remote attackers to achieve code execution. Both the flaws –  CVE-2023-33009 and CVE-2023-33010  – are  buffer overflow vulnerabilities  and are rated 9.8 out of 10 on the CVSS scoring system. A brief description of the two issues is below - CVE-2023-33009  - A buffer overflow vulnerability in the notification function that could enable an unauthenticated attacker to cause a denial-of-service (DoS) condition and remote code execution. CVE-2023-33010  - A buffer overflow vulnerability in the ID processing function that could enable an unauthenticated attacker to cause a denial-of-service (DoS) condition and remote code execution. The following devices are impacted - ATP (versions ZLD V4.32 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2) USG FLEX (versions ZLD V4.50 to V5.36 Patch 1, patched in ZLD V5.36 Patch 2) USG FLEX50(W) / USG20(W
GUAC 0.1 Beta: Google's Breakthrough Framework for Secure Software Supply Chains

GUAC 0.1 Beta: Google's Breakthrough Framework for Secure Software Supply Chains

May 25, 2023 Software Security / Supply Chain
Google on Wednesday announced the  0.1 Beta version  of  GUAC  (short for Graph for Understanding Artifact Composition) for organizations to secure their software supply chains. To that end, the search giant is  making available  the open source framework as an API for developers to integrate their own tools and policy engines. GUAC  aims to aggregate software security metadata from different sources into a graph database that maps out relationships between software, helping organizations determine how one piece of software affects another. "Graph for Understanding Artifact Composition ( GUAC ) gives you organized and actionable insights into your software supply chain security position," Google  says  in its documentation. "GUAC ingests software security metadata, like SBOMs, and maps out the relationship between software so that you can fully understand your software security position." In other words, it's designed to bring together Software Bill of M
