Attribution is usually a difficult course of. Within the case of a DDoS assault, menace actors usually make use of botnets to direct a excessive quantity of visitors to a goal, overwhelming that community and disrupting its service.
After outages at X brought on allegedly by a DDoS assault, loads of folks requested who was accountable. Elon Musk solid blame on Ukraine, Politico studies. Cybersecurity consultants pushed again in opposition to that assertion. In the meantime, Darkish Storm, a pro-Palestinian group, claimed duty, additional muddling makes an attempt at attribution.
“A botnet is usually a community of compromised computer systems. In essence, they [a victim] are being hit from completely different IP addresses, completely different techniques. So, you actually cannot truly pinpoint that it got here from this particular location, which makes it tough to establish root trigger,” explains Vishal Grover, CIO at apexanalytix, a provider onboarding, threat administration, and restoration options firm.
How ought to CIOs and CISOs be occupied with attribution and their very own method when they’re confronted with navigating the aftermath of a cyberattack?

The Significance of Attribution
Attribution is vital. Nevertheless it isn’t essentially the primary precedence throughout incident response.
“The … concern that I most likely would have as a CISO is addressing the vulnerability that allowed them within the door within the first place,” says Randolph Barr, CISO at Cequence Safety, an API and bot administration firm.
As soon as an incident response group addresses the vulnerability and ensures menace actors aren’t lingering in any techniques, they’ll dig into attribution. Who executed the assault? What was the motivation? Getting the solutions to these questions may also help safety groups mitigate the chance of future assaults from the identical group or different teams that leverage related techniques.
After all the bigger the corporate and the extra widespread the disruption, the louder the requires attribution are typically. “When you’ve got a big group like X, there’s going to be lots of people asking questions. When folks become involved, then attribution turns into vital,” says Barr.
For smaller organizations, attribution could also be a decrease precedence as they leverage extra restricted sources to work by way of remediation first.
How one can Deal with Attribution
In some circumstances, attribution could also be fairly easy. For instance, a ransomware gang is more likely to be forthright about their id and their monetary motivations.
However menace actors that step into the limelight aren’t all the time the true culprits. “Generally folks declare publicly that they did it, however you’ll be able to’t actually essentially verify that they really did it. They only might want the eyes on them,” Barr factors out.
Attribution tends to be a sophisticated course of that takes a major period of time and sources: each technical instruments and menace intelligence. Whether or not performed internally or with the assistance of outdoor consultants, the attribution course of usually culminates in a report that particulars the assault and names the accountable social gathering, with various levels of confidence.
Generally you may not get a definitive reply. “There are occasions whenever you will not be capable of decide the foundation trigger,” says Grover.
Attribution and Data Sharing
Attribution may also help a person enterprise shore up its safety posture and incident response plan, however it additionally has worth to the broader safety neighborhood.
“That is one of many major causes that you just go and attend a safety convention or safety assembly. You undoubtedly wish to share your experiences, study from their experiences, and perceive everyone’s perspective,” says Grover.
Risk intelligence and safety groups can collaborate with each other and share details about the teams that focus on their organizations. Risk intel groups may additionally decide up details about deliberate assaults on the darkish net. Sharing that info with potential targets is efficacious.
“We construct these relationships in order that we all know that we will belief one another to say, ‘Hey, if our title comes up, please tell us,’” says Barr.
Not all corporations have a tradition that services that type of info sharing. Cyberattacks include quite a lot of baggage. There’s legal responsibility to fret about. Model injury. Misplaced income. And simply plain embarrassment. Any a kind of components, or a mix thereof, may push enterprises to err on the facet of silence.
“We’re nonetheless making an attempt to determine, as safety professionals, what’s it that may enable for us to have that dialog with different safety professionals and never fear about exposing the enterprise,” says Barr.
