Kroll in Action Cyber Incident Response

Containment and Remediation of Cyberattack That Compromised Personally Identifying Information (PII)

Client: Major Company in U.S. Transportation Industry

Client Problem

The client informed Kroll late on a Friday afternoon that it had suffered a cyberattack. At the outset, the company, which served a large national and international clientele, needed to quickly contain and remediate the impact of the incident. It would then need to notify those whose PII had been compromised and report the incident to regulators.

How Kroll Resolved The Problem

  • Within two hours, we deployed a remote response and had personnel onsite at the company’s headquarters by the next morning. By the end of the weekend (48 hours later) the team had scaled up from two investigators to twelve.  
  • After identifying specific indicators of compromise (IOCs), we were able to eradicate the actor and establish containment. We then monitored the containment strategy to ensure it kept working. 
  • Kroll investigators created a disposition matrix, which they used to cross-reference compromised machines with individuals’ compromised data.

Utilizing the many tools at their disposal, our investigators restored the client’s system with minimal disruption to its operations. Additionally, the findings of our disposition matrix allowed the client to refine its notification list with pinpoint accuracy. As a result, the client was able to notify and address the concerns of a much smaller subset of people, avoiding a costly blanket notification, as well as the intense media coverage that typically ensues. On top of dramatically reducing its notification and remediation costs, the client was also able to provide regulators with precise details of the incident’s scope and effects.
