Identity Protection program.</p>
<p class="MsoNormal" style="margin-bottom:8.0pt;line-height:115%">Experian will issue Dark Web alerts related to the previously disclosed 2021 University of California (UC) Accellion data breach. During Experian's large-breach vetting process, data associated
with the Accellion breach was identified for inclusion in its alerting database. As part of this process, the breached site must be included in CyberAgent alerts. As a result, related notifications will identify "<a href="http://universityofcalifornia.edu/" target="_blank">universityofcalifornia.edu</a>"
as the associated breached site.</p>
<p class="MsoNormal" style="margin-bottom:8.0pt;line-height:115%"><b>Experian has advised:</b></p>

Because this data is now available on the dark web, the risk of misuse has increased.</li><li class="MsoNormal" style="margin-bottom:8.0pt;line-height:115%;mso-list:l1 level1 lfo3">
Individuals receiving these alerts were previously notified of the breach and have likely already taken protective measures.</li><li class="MsoNormal" style="margin-bottom:8.0pt;line-height:115%;mso-list:l1 level1 lfo3">
