Life would not be the same without new popping up that one state level threat actor or another was attacking and compromising US defense contractors or other businesses linked to US national security and defense. The counties of origin for these actors become a blur over time, although you do see some highlighted depending on current political trends. The two most often bandied about are Russia and China with North Korea getting an honorable mention.

Apache and their open-source tools have gotten a lot of press lately. After the Lgo4Shell vulnerability in their Log4J tool, and the massive response from vendors and security organizations we are now learning that researchers have discovered a remote code execution flaw in the NoSQL database management tool Cassandra. This time, unlike Log4J flaw the disclosure comes with a patch already available for installation.

The Threat Landscape is an interesting topic of discussion. It is a constantly changing thing and even the best predictions can often fall short of the actual threat. This is because in most cases, the attackers are a step ahead of the defenders. They have the advantage, to coin a D&D phrase, they won the initiative roll. Defenders are always waiting to see what might happen, they plan without really knowing what the attackers are going to do which means they have to be secure everywhere (not really a possibility). To help them put their resources in the right places, most security teams rely on threat intelligence feeds and an understanding of the Threat Landscape.

A vulnerability disclosed and patched in January is rearing its ugly head. Identified as CVE-2022-21882, this vulnerability affects Windows 10, 11 and Windows Server. On its own it is a significant threat since is allows for a privilege escalation that can turn into a complete compromise of the targeted device. Not exactly what you want to leave open. The good news is that Microsoft released a patch for it in January.

We first talked about the using the UEFI firmware as an attack vector (At Def Con 22 in 2014). Since that time there have been three identified and disclosed versions of malware that directly targeted this critical subsystem. That would seem to be a relatively small percentage given the time since it was first uncovered, the number of devices that operate using the UEFI firmware subsystem, and the time between then and now. However, this is only ones identified and in most of the identified cases were found because of the method of delivery for the OS payload. This begs the question, are there more out there that just have not been found?

Samba has released several updates that patch critical flaws in their popular Sever Message Block (SMB) freeware implementation. SMB is a protocol that allows for simple sharing of network resources and has had its share of critical vulnerabilities in the past. The sharing of network resources is a common target for attackers as it can be a quick an easy way to compromise a system. One of the vulnerabilities includes all versions of Samba before 4.13.17 (CVE-2021-44142).

Yesterday Apple released several patches for their different operating systems. One that we have talked about before is a core bug in Apple’s WebKit based Safari. This bug could potentially leak personal information regardless of the privacy settings you had enabled. In macOS you could always change to another browser that was not WebKit based. On iOS, iPadOS, watchOS and other app store locked devices there was no option as Apple requires every browser to use WebKit for its render engine.

It is a common belief that vulnerability management is nothing more than scanning and patching. However, as we have seen in many breaches and attacks, this is far from true. Vulnerability management is about understanding your organization and the risks it faces. Risks that an organization faces can include insider threats, public exposure, data leakage, improper configurations or safeguards, data integrity models, and quite a bit more. It is not enough to simply scan with a specific flavor of vulnerability scanner, it is a much larger effort and requires buy-in from every team and person in an organization.

We had the chance to sit down with Chris Carlson, vice president of product management for Qualys and talk a little about what Qualys is up to and where they are moving to in the security market. For many Qualys is a name that brings vulnerability management and reporting   to mind. This is due to the fact that this has been their bread and butter for a number of years. Now they are moving into new verticals in the market to expand on their knowledge in this arena. One of the highlights of the talk was in coving their Cloud Agent which brings a whole new set of features to the Qualys product line.
