Attribution could be a difficult course of. Within the case of a DDoS assault, menace actors usually 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 caused allegedly by a DDoS attack, loads of folks requested who was accountable. Elon Musk cast blame on Ukraine, Politico studies. Cybersecurity specialists pushed back 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 mostly 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 troublesome to determine root trigger,” explains Vishal Grover, CIO at apexanalytix, a provider onboarding, danger administration, and restoration options firm.
How ought to CIOs and CISOs be eager about attribution and their very own strategy when they’re confronted with navigating the aftermath of a cyberattack?

The Significance of Attribution
Attribution is vital. However it isn’t essentially the primary precedence throughout incident response.
“The … concern that I in all probability 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 Security, an API and bot administration firm.
As soon as an incident response crew 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 might help safety groups mitigate the chance of future assaults from the identical group or different teams that leverage related ways.
After all the bigger the corporate and the extra widespread the disruption, the louder the requires attribution are usually. “When you might have a big group like X, there’s going to be lots of people asking questions. When people 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.
The best way to Deal with Attribution
In some circumstances, attribution could also be fairly easy. For instance, a ransomware gang is prone to be forthright about their id and their monetary motivations.
However menace actors that step into the limelight aren’t at all times the true culprits. “Generally folks declare publicly that they did it, however you may’t actually essentially affirm that they really did it. They simply 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 finished internally or with the assistance of out of doors specialists, the attribution course of sometimes 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 foundation trigger,” says Grover.
Attribution and Info Sharing
Attribution might help a person enterprise shore up its safety posture and incident response plan, but it surely additionally has worth to the broader safety group.
“That is one of many main causes that you just go and attend a safety convention or safety assembly. You undoubtedly 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 also 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 will belief one another to say, ‘Hey, if our identify comes up, please tell us,’” says Barr.
Not all firms have a tradition that services that sort of data sharing. Cyberattacks include a variety of baggage. There’s legal responsibility to fret about. Model harm. Misplaced income. And simply plain embarrassment. Any a type of components, or a mixture 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 might permit for us to have that dialog with different safety professionals and never fear about exposing the enterprise,” says Barr.
