Kroll in Action

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

Client: Major Company in U.S. Transportation Industry

Client Problem

The client contacted Kroll late on a Friday afternoon that it had suffered a cyberattack. The organization, which served a large national and international clientele, needed to contain and remediate the incident. It also would need to notify persons whose PII had been compromised and report the incident to regulators. 

How Kroll Resolved The Problem

  • Kroll deployed a response within two hours and had personnel onsite at the client’s headquarters by the next morning. The team eventually scaled from two investigators to 12 within 48 hours over the weekend. 
  • Upon identifying specific indicators of compromise (IOCs), we were able to eradicate the actor and establish containment; we also provided ongoing monitoring of the containment strategy to help assure effectiveness.
  • We created a disposition matrix, whereby we cross-referenced compromised machines with compromised individuals’ data.

Our investigators were able to restore the client’s system with minimal disruption to its operations. Additionally, the findings of our disposition matrix enabled the client to refine its notification list with pinpoint accuracy.

Consequently, instead of implementing costly blanket notification (which also often generates intense media coverage), the client was able to notify and address the concerns of a much smaller subset of affected persons. The client ultimately not only dramatically reduced its notification and remediation costs, but also was able to provide regulators with precise details of the incident’s scope and effects.
