All of us at Tripwire’s Vulnerability Exposure and Research Team (VERT) are constantly reviewing the news for interesting stories and developments in the cybersecurity world. Here’s what stood out to us during the week of September 27, 2021. We’ve also included the comments from a few folks here at Tripwire VERT.   REvil Ransomware Group Goes Offline ...

In this episode, Patrick Miller, Founder of Ampere Industrial Security, discusses what utilities and other industrial companies need to consider when it comes to the goldmines of data they're collecting from their machines and customers. He also explains why security and privacy needs to be incorporated in these operations by design. https://open...

CIS Control 6 merges some aspects of CIS Control 4 (admin privileges) and CIS Control 14 (access based on need to know) into a single access control management group. Access control management is a critical component in maintaining information and system security, restricting access to assets based on role and need. It is important to grant, refuse, and...

Knowing who has credentials, how those credentials are granted, and how they are being used is the foundation of any secure environment. It begins with user accounts and the credentials they use. Maintaining a thorough inventory of all accounts and verifying any changes to those accounts as authorized and intentional vs unintended is paramount to...

Key Takeaways for Control 4 Most fresh installs of operating systems or applications come with pre-configured settings that are usually insecure or not properly configured with security in mind. Use the leverage provided by multiple frameworks such as CIS Benchmarks or NIST NCP to find out if your organization needs to augment or adjust any baselines...

Today’s VERT Alert addresses Microsoft’s September 2021 Security Updates. VERT is actively working on coverage for these vulnerabilities and expects to ship ASPL-964 on Wednesday, September 15th. In-The-Wild & Disclosed CVEs CVE-2021-40444 This CVE describes a publicly exploited vulnerability in MSHTML that provides user level access upon successful...

For many years, there was a wide misunderstanding that encrypting some data is equivalent to protecting that data. If it’s encrypted, so the thinking goes, nobody else could access it, and it is therefore safe. While it is critical to encrypt data at rest as well as in transit, the job of protecting data goes much deeper. Encryption can mitigate risk...

Today, I will be going over CIS Control 2 from version 8 of the top 18 CIS Controls – Inventory and Control of Software Assets. Version 7 of CIS Controls had 10 requirements, but in version 8, it's simplified down to seven safeguards. I will go over those safeguards and offer my thoughts on what I’ve found. Key Takeaways for Control 2 Reusability. The...

Since 2008, the CIS Controls have been through many iterations of refinement and improvement, leading up to what we are presented with today in CIS Controls version 8. CIS Controls reflect the combined knowledge of experts from every part of the ecosystem (companies, governments, and individuals). The controls reflect consideration by people in many...

Throughout this blog series, I have examined real-world ICS cyber-related incidents as a way of looking back to predict what the next attack may look like. The three categories of attacker that I have considered so far are disgruntled insiders, ransomware groups, and APT. Knowing about past events, their impact, and how they unfolded can be critical for...

No discussion on ICS attacks could be complete without talking about what some would call, ‘the elephant in the room.’ Critical infrastructure has always been a target for warfare, and modern ICS are no exception. Several high-profile ICS disruptions have in fact been attributed to malicious hackers working at the behest of a military or intelligence...

OT networks often rely on Windows systems for various ICS applications including HMIs, historians, and data gateways. Beyond that, they also commonly rely on Windows systems to run associated IT-networks. A successful ransomware deployment into either of these networks may prevent engineers from controlling plant operations and lead to an unplanned...

Today’s VERT Alert addresses Microsoft’s August 2021 Security Updates. VERT is actively working on coverage for these vulnerabilities and expects to ship ASPL-959 on Wednesday, August 11th. In-The-Wild & Disclosed CVEs CVE-2021-36948 This privilege escalation vulnerability that affects the Windows Update Medic Service (WaasMedic) has been actively...

Often, the most critical threats come from within an organization itself. This is true for all sectors, but it is especially true for industrial control systems (ICS). Technicians in these environments already have access to plant controls and may have the deep knowledge of industrial processes needed to achieve specific goals. The damage caused by an...

Faced with rows of empty gas pumps, many Americans on the East Coast may be wondering why this happened, whether it will happen again, or if there is anything we can do to avoid future catastrophe. The unpleasant truth of the matter is that this will certainly not be the last time society is disrupted due to attackers targeting critical industrial...

Today’s VERT Alert addresses Microsoft’s July 2021 Security Updates. VERT is actively working on coverage for these vulnerabilities and expects to ship ASPL-954 on Wednesday, July 14th. In-The-Wild & Disclosed CVEs CVE-2021-34527 The vulnerability dubbed PrintNightmare was patched prior to the Tuesday patch drop, but it is still worth including here....

Back in 2018, the State of Security spent a lot of time going over v7 of the Center for Internet Security’s Critical Security Controls (CIS Controls). We noted at the time how the Center for Internet Security shuffled the order of requirements for many of the existing controls in that version. It also cleaned up the language of the CIS Controls,...

Today’s VERT Alert addresses Microsoft’s June 2021 Security Updates. VERT is actively working on coverage for these vulnerabilities and expects to ship ASPL-947 on Wednesday, June 9th. In-The-Wild & Disclosed CVEs CVE-2021-31955 This is one of two vulnerabilities fixed in today’s patch drop which were reported by Kaspersky Lab after detecting...

Given that attacks are only increasing and there needs to be greater efficacy in how companies protect themselves, let us reference how the financial industry has created and relies on a body of standards to address issues in financial accounting as a defined comparison for Information Security. To support this argument, there is a defined contrast...
