I am concerned about identify theft, what action do I need to take?
At this time, you do not need to take any action. As a precaution, we encourage customers to remain alert for phishing emails, phone calls, or text messages from individuals claiming to represent ADT and to avoid clicking links or sharing personal information unless the source has been verified.
What is ADT doing to assist customers that have been impacted?
We will offer complimentary identity protection services, as appropriate. Those who had private information exposed, such as the last four digits of their Social Security number or Tax ID, will receive mailed notification regarding identity monitoring through Cyberscout with details on how to sign up.
Who is Cyberscout?
Cyberscout is a TransUnion company that specializes in fraud assistance and remediation services.
What will happen if I find out my identity has been stolen?
In the unlikely event that your information is misused, a personal advocate will work with you from the first call you make to report the problem until the crisis is resolved. Cyberscout will notify the appropriate agencies, businesses, institutions, and create a comprehensive case file.
Why did I hear about this from my credit reporting agency instead of ADT?
We understand how concerning it can be to learn about something like this from another source, and we're sorry for any confusion or worry this may have caused. In some cases, credit reporting agencies notify individuals proactively based on their own monitoring services or contractual obligations. Their notifications are not always based on the specific level of exposure involved and often include alerts related to the sharing of publicly available information. As a result, those notifications can occur independently and before a company's direct outreach. ADT is following all applicable legal and regulatory requirements and is committed to communicating directly and transparently with impacted individuals as quickly as possible.
