Earlier this yr we held a stay broadcast, that includes cybersecurity menace analysts from throughout Cisco Safe. We mentioned essentially the most important cyber threats of 2021, what we’re seeing now, and the way defenders can greatest shield their organizations within the yr forward. Within the first of this three-part collection, we’ve compiled some transient 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 possibly can have chosen to speak about, why did you select Colonial Pipeline?
Matt Olney, Director of Cisco Talos Menace Intelligence and Response: There’s two issues that I discovered fascinating about Colonial Pipeline…
One is the real-world affect of the assault, i.e what occurred to gasoline provides on the East Coast of the US. The assault impressed political stress, and that subsequently led to a rise in response velocity from the US authorities on ransomware actions.
On the flip aspect, the response from the unhealthy actors was additionally fascinating. It was very a lot an ‘Icarus’ state of affairs. They knew that they’d overstepped. And there was an instantaneous and profound response from that atmosphere.
What do we all know in regards to the unhealthy actor aspect of this assault?
MO: Instantly, there was chatter on underground boards and the darkish internet about the truth that this was a mistake.
Actually, numerous ransomware teams rolled out a proper coverage. It stated, “This group doesn’t assault important infrastructure or hospitals.”
We additionally noticed numerous underground boards instigate sure new guidelines, which informed folks that they might not promote ransomware companies right here. This was probably as a result of they wished to evade the eye of legislation enforcement, and the form of consideration that being related to ransomware brings. This hasn’t gone away within the months since.
The unhealthy actors have understood that this occasion modified the calculus, by way of how nations 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, loads of authorities response up had been about info sharing; getting the message out. Then they might depend on conventional legislation 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 may cause.
The ransomware menace continues to be at a important stage for sure actors and, subsequently, you could deal with these actors as Nationwide Safety threats. Which means you could deliver within the full scope of presidency response.
Moreover, with ransomware, we’ve at all times been involved in regards to the breadth {that a} provide chain assault may deliver. In 2017, we noticed what a ransomware-like occasion may appear like when delivered by way of provide chain, with NotPetya. That assault triggered over $10 billion in damages globally.
To be clear, that was a purely damaging state-sponsored assault, not ransomware, however 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 Rising Goal of Alternative
What’s safety debt and why is it turning into more and more important?
Dave Lewis, Advisory CISO, Cisco Safe: Safety debt is when organizations use techniques which have depreciated or aren’t being correctly maintained. Consequently, this introduces all kinds 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 may they exploit safety debt inside a company?
DL: The attacker can take 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 way of LinkedIn and seeing what folks put of their resumes i.e they work on a specific product.
They will then distil down the merchandise that had been presumably utilized in that atmosphere, after which evaluate towards vulnerabilities which can be both revealed or they’ll discover on the darkish internet. They will then construct up a profile of that group, and goal it based mostly 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 atmosphere, who’re the customers in your atmosphere, and what are the functions and the {hardware}? Make these inventories out there so you already know what it’s that you simply’re making an attempt to guard.
- Have a threat register to have the ability to monitor points as they’re recognized. It’s also possible to use this for auditors. Your threat register can inform them that you simply’ve recognized points, and the roadmap you’ve gotten in place for these points.
- The largest piece of the puzzle — outline repeatable processes. I’ve labored in organizations previously the place when one thing went fallacious, 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 determine the folks inside your name chain you need to name when one thing goes fallacious, and who has which duties to care for. Importantly, don’t tag it to a person by identify. Tag it to a job, and that may assist remedy the issue of when folks come and go all through the group.

Essentially the most important vulnerabilities (you may not be serious 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 take a look at 55 CVEs a day and may perceive which of them necessary and which of them will not be.
We run a mannequin each night time, and it appears to be like like there’s going to be over 23,000 CVEs this yr. So, we all know that this can be a drawback that’s rising larger.
The reality is that whereas we discuss lots about vulnerabilities which can be common (all people is aware of about Log4j and the Microsoft Trade vulnerability that got here out early 2021), we’re seeing extra vulnerabilities come by way of on Chrome and Edge in big waves.
PrintNightmare was one of the crucial impactful vulnerabilities of 2021. It was so widespread that in the long run, 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 group’s time throughout 2021? Are you able to spotlight a few of the prime vulnerabilities?
JG: We spent loads of time on the Chrome V8 engine. Microsoft additionally made a considerable change this yr after they moved from Web Explorer. Now it’s based mostly 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 loads of virtualization vulnerabilities turning into more and more frequent. We noticed loads of VMware vulnerabilities this yr that we’ve got hadn’t seen previously.
And we’re beginning to see the emergence of what we internally name “Pile-on CVEs.” (We don’t have time period for it but…).
For instance, a base CVE may come out, after which over the following couple of weeks, you may say, “I appeared on the code as a result of it was fascinating. 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 tendencies you could level to?
JG: We all know that CVSS isn’t an ideal 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 stated Twitter is a greater indicator of exploitability. What you need to search for typically isn’t within the CVSS rating.
Organizations actually need to maneuver to a risk-based vulnerability administration system, the place you’re potential distant code executions. Or if there’s a launched exploit code for it (that’s the largest factor that you are able to do). And what are you able to do to make it possible for the vulnerabilities in your community are being addressed correctly?
That will help you keep updated, our weblog, weblog.Kennasecurity.com has the Prioritization to Predication report which discusses how one can scale back threat with vulnerability prioritization based mostly on threat and real-world exploitation information. And I’ve a private undertaking that runs a pocket book every single day at CVE.ICU that does open-source information evaluation on the CVE information set.
