Earlier this yr we held a stay broadcast, that includes cybersecurity menace analysts from throughout Cisco Safe.
We mentioned essentially the most vital cyber threats of 2021, what we’re seeing now, and the way defenders can greatest defend their organizations within the yr forward.
Within the first of this three-part sequence, we’ve compiled some temporary highlights from the published. Make sure to watch the movies for extra in-depth evaluation.
Colonial Pipeline, and The New World of Infrastructure Safety
From all of the threats you may have chosen to speak about, why did you select Colonial Pipeline?
Matt Olney, Director of Cisco Talos Risk Intelligence and Response: There’s two issues that I discovered attention-grabbing about Colonial Pipeline…
One is the real-world affect of the assault, i.e what occurred to fuel provides on the East Coast of the US. The assault impressed political strain, and that subsequently led to a rise in response pace from the US authorities on ransomware actions.
On the flip facet, the response from the dangerous actors was additionally attention-grabbing. It was very a lot an ‘Icarus’ scenario. They knew that that they had overstepped. And there was an instantaneous and profound response from that setting.
What do we all know in regards to the dangerous actor facet of this assault?
MO: Instantly, there was chatter on underground boards and the darkish internet about the truth that this was a mistake.
Actually, varied ransomware teams rolled out a proper coverage. It mentioned, “This group doesn’t assault crucial infrastructure or hospitals.”
We additionally noticed varied underground boards instigate sure new guidelines, which advised folks that they might not promote ransomware providers right here. This was doubtless as a result of they needed to evade the eye of regulation enforcement, and the form of consideration that being related to ransomware brings. This hasn’t gone away within the months since.
The dangerous actors have understood that this occasion modified the calculus, by way of how international locations deal with ransomware actors.
You gave a quote in an article simply after the assault – “It’s time to maneuver past ransomware ideas and prayers.” Why did you say that?
MO: Up till this level, numerous authorities response up had been about info sharing; getting the message out. Then they might depend on conventional regulation enforcement methodologies to go after these teams.
Sadly, it’s been clear for some time that this wasn’t viable. The arrest document was extremely poor, in distinction with the catastrophic affect that ransomware could cause.
The ransomware menace continues to be at a crucial degree for sure actors and, due to this fact, you must deal with these actors as Nationwide Safety threats. Meaning you must convey within the full scope of presidency response.
Moreover, with ransomware, we’ve all the time been involved in regards to the breadth {that a} provide chain assault might convey. In 2017, we noticed what a ransomware-like occasion might appear like when delivered by provide chain, with NotPetya. That assault induced over $10 billion in damages globally.
To be clear, that was a purely damaging state-sponsored assault, not ransomware, nevertheless it was meant to appear like ransomware.
Provide chain is the toughest drawback in safety proper now. I can’t consider the rest that’s that’s as flummoxing.

Safety Debt: An Growing Goal of Alternative
What’s safety debt and why is it changing into more and more crucial?
Dave Lewis, Advisory CISO, Cisco Safe: Safety debt is when organizations use methods which have depreciated or aren’t being correctly maintained. In consequence, this introduces all types of targets of alternative for an attacker.
I characterize it as technological debt, that has manifested as a safety concern.
From an attacker standpoint, how might they exploit safety debt inside a company?
DL: The attacker can have a look at it from some ways. They may use Shodan or scanning or do one thing so simple as open-source intelligence, like going by LinkedIn and seeing what individuals put of their resumes i.e they work on a selected product.
They’ll then distil down the merchandise that have been probably utilized in that setting, after which examine towards vulnerabilities which can be both printed or they’ll discover on the darkish internet. They’ll then construct up a profile of that group, and goal it primarily based on what intelligence they’ve gathered.
What’s your recommendation to group’s listening who may need safety debt and wish that debt to be addressed?
- DL: Discover out what are the belongings inside your setting, who’re the customers in your setting, and what are the functions and the {hardware}? Make these inventories out there so you understand what it’s that you just’re making an attempt to guard.
- Have a threat register to have the ability to observe points as they’re recognized. You can too use this for auditors. Your threat register can inform them that you just’ve recognized points, and the roadmap you’ve in place for these points.
- The largest piece of the puzzle — outline repeatable processes. I’ve labored in organizations up to now the place when one thing went incorrect, all people would run round with their hair on fireplace, making an attempt to determine who needed to do. Just be sure you have a course of in place which might establish the individuals inside your name chain you need to name when one thing goes incorrect, and who has which duties to care for. Importantly, don’t tag it to a person by identify. Tag it to a task, and that may assist remedy the issue of when individuals come and go all through the group.

Probably the most crucial vulnerabilities (you may not be desirous about…)
Jerry, what are you able to inform us in regards to the world of vulnerabilities?
Jerry Gamblin, Director of Safety Analysis, Kenna Safety (now a part of Cisco): Final yr, we noticed over 20,000 CVEs (Frequent Vulnerabilities and Exposures) for the primary time ever. That’s 55 CVEs a day.
I don’t know many safety groups which can be staffed to the extent of with the ability to have a look at 55 CVEs a day and might perceive which of them vital and which of them aren’t.
We run a mannequin each evening, and it seems like there’s going to be over 23,000 CVEs this yr. So, we all know that it is a drawback that’s rising larger.
The reality is that whereas we speak so much about vulnerabilities which can be common (all people is aware of about Log4j and the Microsoft Alternate vulnerability that got here out early 2021), we’re seeing extra vulnerabilities come by on Chrome and Edge in enormous waves.
PrintNightmare was probably the most impactful vulnerabilities of 2021. It was so widespread that ultimately, Microsoft set an instruction to return to needing an admin to put in printers. It actually modified the dynamic of how safety groups work on this enviornment.
What occupied your crew’s time throughout 2021? Are you able to spotlight among the high vulnerabilities?
JG: We spent numerous time on the Chrome V8 engine. Microsoft additionally made a considerable change this yr once they moved from Web Explorer. Now it’s primarily based off Chromium, so we’re ensuring our prospects perceive the change from an open-source browser from a closed supply browser.
We’re additionally seeing numerous virtualization vulnerabilities changing into more and more frequent. We noticed numerous VMware vulnerabilities this yr that we’ve hadn’t seen up to now.
And we’re beginning to see the emergence of what we internally name “Pile-on CVEs.” (We don’t have a superb time period for it but…).
For instance, a base CVE would possibly come out, after which over the subsequent couple of weeks, you would possibly say, “I seemed on the code as a result of it was attention-grabbing. And I discovered this CVE, and this CVE, and this CVE…”
What do these findings and actions that occurred in 2021 let you know about what defenders may need to face this yr? Are there any vulnerability traits which you can level to?
JG: We all know that CVSS isn’t a terrific predictor of exploitability – and we’re not saying something right here that CVSS themselves don’t say themselves. After we launched our newest Precedence to Prediction report, we made the information as a result of we mentioned Twitter is a greater indicator of exploitability. What you need to search for usually isn’t within the CVSS rating.
Organizations really want to maneuver to a risk-based vulnerability administration system, the place you’re taking a look at potential distant code executions. Or if there’s a launched exploit code for it (that’s the most important factor that you are able to do). And what are you able to do to guarantee that the vulnerabilities in your community are being addressed correctly?
That can assist you keep updated, our weblog, weblog.Kennasecurity.com has the Prioritization to Predication report which discusses how one can cut back threat with vulnerability prioritization primarily based on threat and real-world exploitation knowledge. And I’ve a private challenge that runs a pocket book day by day at CVE.ICU that does open-source knowledge evaluation on the CVE knowledge set.
