Cybersecurity digerati spends an inordinate amount of time focusing on the concept of “biggest” when it comes to cybersecurity threats. While there is some merit to such quantification, the concept itself can be difficult to generalize, since every organization has some set of unique characteristics that cause each of them to have fairly unique threat profiles, risk tolerances, and exposures.
We can, however, break down some of the broader themes from Black Hat and DEF CON 2023 and pull out some recurring themes across each that would cause some consternation for CISOs, CIOs, CEOs, and board members (since many of them are now on the hook when cyber things go south).
Recurring - Theme 1: Insecure By Default CPUs
Meltdown, Spectre, and L1 Terminal Fault (Foreshadow) may be behind us, but modern processor architectures seem to be in a permanent state of vulnerability. Downfall is yet another one in this line of low-level flaws that require significant effort to mitigate, as said mitigations usually require some downtime and also some inherent risk in the patch processes themselves.
Fixing these vulnerabilities also may cause significant performance degradation, which may force organizations to incur extra spend to meet pre-projected capacity requirements.
C-suite folks are left with a gnarly, tangled risk assessment process that has to consider the likelihood and frequency of projected attacks and also the potential impact on various compliance requirements if they choose not to patch/mitigate.
This is a major distraction from delivering on core business functions, and we’re likely to see more of these types of vulnerabilities in the future, especially with the scramble to acquire GPUs. CVE-2022-31606, CVE-2021-1074, and CVE-2021-1118 are already known vulnerabilities in GPUs, and the rush to meet AI headfirst may see a parallel set of headaches on the horizon in any systems that are performing advanced ML/AI processing.
Recurring - Theme 2: Trouble In The Cloud
It’s no secret that an ever-increasing number of organizations are moving some or many workflows to cloud environments, joining the ranks who have blazed the trail before them. There was supposed to be some inherent level of trust in cloud providers to take security seriously, so all an organization had to do was ensure they didn’t mess up their configs or expose vulnerable services. Sadly, that has not been the case for some time now.
The specifics of what were presented at or before Hacker Summer Camp in this space really aren’t as important as the theme itself: you can no longer even remotely have any baseline level of assurance that the cloud environments you are adopting are taking security measures seriously.
This puts C-suite folks in a precarious position. While some cloud plans end up going over budget, there are many cloud use cases that do help organizations save time, money, and people resources. Yet, when you are put at serious risk due to negligence on the part of a cloud provider you have the potential of incurring significant costs for triage, incident response, and potentially data breach penalties.
2023 has made it pretty clear that “In Cloud, We Trust” is unlikely to ever be a motto again (if it ever was). Organizations now have extra complexity both up-front (as they bake in extra security measures and potential incident costs into new endeavors) and also as they handle the distraction of retrofitting a more defensive security posture onto systems that were likely more secure when they were hosted back in the “owned data center” days.
Recurring - Theme 3: AI Insecurity
There has been enough discussion about “AI insecurity” ever since just around this time last year, so I can keep this relatively brief.
The large language/generative models (LLM/GPTs) we seem to be stuck working with were all trained with no thought for safety — either in the results one gets when using them, or for how easy it is to cause them to reveal information they shouldn’t.
They also come with an equivalent to the “cloud” problem mentioned above, since most organizations lack the skill and resources necessary to bring AI fully in-house.
This is a big topic of discussion when I talk to CISOs in my lectures at CMU. The AI gold rush is causing organizations to incur significant, real risk, and there are almost no tools, processes, guides, or bulk expertise to help teams figure out ways to keep their data, systems, and humans safe from AI exposures.
This is yet one more distraction, and focus grabber that makes it very difficult to just get “normal” cybersecurity practices done. Unless the bottom falls out of generative AI as it has with the web3/crypto fad that came before it, the C-suite will have to dedicate what little time and resources they have to corralling and shaping AI use across the organization.
Missing - Theme 4: The Vulns Start Coming And They Don’t Stop Coming
There were many talks about vulnerabilities in general at both Hacker Summer Camp and RSA this year. But, I don’t think any talk made the brutal reality of what it is like to perform the thankless task of vulnerability management within even a moderately sized organization.
That calendar view has a colored square every time there’s been a CISA Known Exploited Vulnerability release since CISA began curating their catalog. Apart from the regular mega “Patch Tuesday” organizations have to deal with, they also have to contend with nigh immediate response to each new update, even if that’s only a triage event. There is little time in-between updates, and very common technologies/products make their way to the list on-the-regular.
Six weeks before Black Hat, there was at least one, major vulnerability in a core component of most enterprise IT stacks every week, with rapid and devastating malicious attacks following close behind each release.
This is an untenable situation for most organizations, even “resource rich” ones.
Hundreds (one estimate, today, said “thousands”) of organizations have been devastatingly hurt by MOVEit exploits, Citrix admins likely cannot sleep at night anymore, and even security teams have had to face an onslaught of patches for technology they’re supposed to be using to keep their organizations safe.
We rarely talk about this because it’s a hard problem to solve and causes real, lasting damage. It’s far “cooler” to talk about that “EPIC vulnerability” some clever researcher found in isolation. But, when they’re disclosed back-to-back, as a few security vendors did before Black Hat, it quickly moves from “cool” to a cold, hard annoyance.
More work needs to be done at and outside Summer Camp to help figure out ways to enable defenders to keep their own shops safe without dealing with the IT equivalent of a weekly hurricane sweeping across their asset landscapes.
Getting Off The Hamster Wheel Of Pain
“Recurring theme” is just a fancy way of saying we’re repeating the same negative patterns of the past and making little to no headway, or — to put it another way — we’re in a “two steps forward; three steps back” operational model as we work to overcome each new challenge.
However, all is not doom and gloom, and there are ways to strive for more positive outcomes.
Fundamentally, organizations must take a proactive and pragmatic approach to enhance their security posture.
For CPU vulnerabilities, investigate tools that can help detect and mitigate risks, and have a plan to rapidly patch and potentially downgrade performance if needed. Cloud providers should be evaluated closely, with redundancy and controls to limit damage from potential exposure. AI and generative models require robust testing, monitoring, and human oversight to prevent harmful outcomes.
Most crucially, vulnerability management programs require sufficient staffing, automation, and executive buy-in. Prioritization aligned to business risk can help focus limited resources. Communication and collaboration with vendors, regulators, and peer organizations could also move the needle on systemic issues.
While hacker conventions highlight scary scenarios, security leaders who take balanced action can still fulfill their mission to protect their organizations. With vision, realism, and tenacity, progress is possible even in the face of ongoing challenges.
