Attribution is usually a tough course of. Within the case of a DDoS assault, risk actors typically make use of botnets to direct a excessive quantity of site visitors to a goal, overwhelming that community and disrupting its service.
After outages at X precipitated allegedly by a DDoS assault, loads of folks requested who was accountable. Elon Musk forged blame on Ukraine, Politico reviews. Cybersecurity specialists pushed again towards that assertion. In the meantime, Darkish Storm, a pro-Palestinian group, claimed accountability, 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 totally different IP addresses, totally different methods. So, you actually cannot really 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 necessary. However 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 risk actors aren’t lingering in any methods, they will dig into attribution. Who executed the assault? What was the motivation? Getting the solutions to these questions can assist safety groups mitigate the danger of future assaults from the identical group or different teams that leverage related techniques.
In fact 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 other people get entangled, then attribution turns into necessary,” says Barr.
For smaller organizations, attribution could also be a decrease precedence as they leverage extra restricted assets to work by remediation first.
How one can Deal with Attribution
In some instances, 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 risk actors that step into the limelight aren’t all the time the true culprits. “Generally folks declare publicly that they did it, however you possibly can’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 assets: each technical instruments and risk intelligence. Whether or not accomplished internally or with the assistance of outdoor specialists, 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 once you will not be capable to decide the basis trigger,” says Grover.
Attribution and Data Sharing
Attribution can assist a person enterprise shore up its safety posture and incident response plan, but it surely additionally has worth to the broader safety neighborhood.
“That is one of many major causes that you simply go and attend a safety convention or safety assembly. You positively need to share your experiences, study from their experiences, and perceive all people’s perspective,” says Grover.
Risk intelligence and safety groups can collaborate with each other and share details about the teams that concentrate on their organizations. Risk intel groups may additionally choose up details about deliberate assaults on the darkish internet. Sharing that data with potential targets is effective.
“We construct these relationships in order that we all know that we are able to belief one another to say, ‘Hey, if our title comes up, please tell us,’” says Barr.
Not all firms have a tradition that services that type of data sharing. Cyberattacks include a whole lot of baggage. There’s legal responsibility to fret about. Model harm. Misplaced income. And simply plain embarrassment. Any a kind of elements, or a mixture thereof, might push enterprises to err on the aspect of silence.
“We’re nonetheless attempting to determine, as safety professionals, what’s it that might permit for us to have that dialog with different safety professionals and never fear about exposing the enterprise,” says Barr.
