The home security systems company ADT Inc. announced Wednesday that unauthorized hackers unlawfully broke into some databases storing customer order information.
The company said the incident happened “recently” but did not provide the date for the intrusion, according to a filing with the Securities and Exchange Commission (SEC).
ADT said that once it learned of the incident, it quickly worked to block the unauthorized access and began investigating the hack with the help of external cybersecurity experts.
Attackers made off with “limited” customer information, including email addresses, phone numbers and home addresses, ADT said.
The company said its probe has turned up no evidence that customers’ home security systems were accessed and that there is no sign the hackers accessed sensitive data such as customer banking information or credit card data.
ADT said it is still investigating the hack and has let the impacted customers know their information was obtained. The company also said the affected customers “comprise a small percentage of the company’s overall subscriber base.”
“While the investigation remains ongoing, as of the date of this filing, the company believes this cybersecurity incident has not materially impacted its operations,” an ADT statement in the SEC filing said.
