When completinThe At-Risk Timeframe refers to the period of time data elements, such as account data, were at risk for this Entity Under Investig the spreadsheet referencedation during the incident under investigation. A data element is considered at risk if evidence indicates the data element withinas exposed (i.e. per the Final PFI Report under Appendix C: Impactedtemplate v3.3, Section 3.4 “a data element was accessible to the Entitiesy under investigation or any unauthorized entity, an account is considered ?at risk? if evidence indicates the account number was exposed (iprocess, source, etc.e. accessible to any unauthorized entity, process, source, etc.”) during the incident under investigation. The ?At-Risk Timeframe? refers to the period of time the account numbers for this breached entity were at risk during the incident under investigation.

The "At-Risk Timeframe" as identified in the Final PFI Report template, Appendix C refers to the period of time during the incident under investigation when data was vulnerable. For example, consider a scenario where evidence (e.g., system/access logs) indicates that an unauthorized entity breached the cardholder data environment?'s security controls on 2024-04-14T18:30:00 and was discovered by the breached entity (who subsequently took the system offline to limit the exposure) 2024-04-17T07:15:00.

The at-risk timeframe is considered to have been from 6:30PM on April 14th when the breach occurred, through 7:15AM on April 17th when the breached system was taken offline (approximately 60 hours).

Further considering the scenario above, suppose the breached entity had several years?' worth of account numdata elements stored in the environment. In this case, regardless of how many data elements were exposed or how long they were stored, the at-risk timeframe:

would not date bers stored in the environment; the ?at-risack timeframe? would not date back to the oldest account numbero the oldest data element stored, as the at-risk timeframe only refers to the timeframe itself ? the period of time the account numbernd
only refers to the timeframe itself — the period of time the data elements were at risk (approximately 60 hours in this scenario) ? regardless of how many numbers were exposed or how long they were stored. Details about the data exposed/at risk are co
