Physical Security Firm ADT Confirms Hack and Data Breach

ADT has confirmed that hackers have stolen information after 30,000 customer records were leaked recently.

ADT, a provider of alarm and other physical security systems for homes and small businesses, has confirmed that hackers have stolen customer information from its systems.

In a filing with the SEC, ADT said hackers recently accessed certain databases containing customer order information. 

The company’s investigation to date shows that the attackers obtained “limited customer information” such as email addresses, phone numbers, and postal addresses. 

“Based on its investigation to date, the Company has no reason to believe that customers’ home security systems were compromised during this incident. Additionally, the Company has no reason to believe the attackers obtained other personally sensitive information such as credit card data or banking information,” ADT said.

“The Company is continuing its investigation into this cybersecurity incident and has notified the customers it believes to have been affected, who comprise a small percentage of the Company’s overall subscriber base,” it added.

ADT believes the cyberattack will likely not have a material impact.

The confirmation from ADT comes roughly one week after a threat actor claimed on a popular hacking forum that they had obtained over 30,000 ADT customer records, including emails and physical addresses. 

The hacker made available a sample of the data to demonstrate the claims.
