Security company ADT, which provides residential and commercial electronic security, fire protection and other alarm monitoring services, has been hacked. The threat actors obtained limited customer information, including email addresses, phone numbers and postal addresses. The company stated that it has no reason to believe the hackers compromised home security systems or sensitive information. However, this security breach raises serious questions about data security.

What you need to know about the ADT hack

In an SEC filing dated Aug. 3, ADT confirmed that it suffered “a cybersecurity incident” during which hackers gained access to “certain databases containing ADT customer order information.” The company stated that despite taking swift action upon discovering the incident, the hackers managed to steal “limited customer information, including email addresses, phone numbers, and postal addresses.”

The security company, which had 6 million customers as of June 2024, offers its products throughout the United States. ADT didn’t specify the number of customers affected by the hack, and the wording in the SEC filing portrays the incident as a very minor one. This is a trend we’ve seen, where companies first downplay the incident and later reveal the exact damage caused.

For example, insurance giant Prudential initially reported that only 36,545 users were affected, but it later revised the breach notice to state that 2.5 million were affected by the February incident.

Is your home security system compromised?

ADT clarified in its SEC filing that it doesn’t believe that customers’ home security systems or other information, such as credit card data or banking information, have been affected. However, the company did not reveal how it reached that conclusion. The disclosure follows a seller on a cybercrime forum claiming that they had obtained more than 30,000 stolen ADT customer records.

We contacted ADT for comment on this article, and a company spokesperson provided the following statement.

“ADT has determined that an unauthorized individual(s) gained access to certain ADT customer information. The company took immediate action; implemented our cybersecurity protocols, increased our alert levels, and began a forensic review of our systems. We can confirm that none of our customers’ home security systems were compromised and no personally sensitive information credit card data, or banking information was accessed.

“Our customers’ privacy and security is our utmost priority, and we have taken several steps to help keep their information safe, including immediately activating rigorous cybersecurity protocols.

“A dedicated support team is standing by at (866) 437-9016 to assist customers and answer any questions.”

4 ways to protect yourself and your home in the wake of the ADT hack

The ADT hack is concerning, and if you’re a customer, below are some steps you should consider taking to protect your privacy and security.

1) Opt for a reliable home security system: While ADT is one of the largest home security companies in the U.S., the recent breach of customer information highlights potential vulnerabilities despite the company’s assurance that home security systems were not compromised. There are many other options on the market that you can consider, whether you like a professionally installed system or a do-it-yourself one. For reference, you can check out my guide on the best home security systems, where I’ve listed four of my favorite options. You might also want to find out if your home insurance offers a discount for installing robust security protection. 

2) Invest in removal services: The ADT hack exposed a limited amount of customer information, including postal addresses, email addresses and phone numbers, which can be misused by hackers. ADT confirmed that no credit card or banking information was compromised, but the exposed data could still be used for phishing or other malicious activities. You can invest in a removal service to get this data removed from the web. While no service can promise to remove all your data from the internet, having a removal service is beneficial if you want to continuously monitor and automate the process of removing your information from hundreds of sites over a longer period. Check out my top picks for data removal services here.

3) Be wary of mailbox communications: Bad actors may also try to scam you through snail mail. The data leak gives them access to your address. They may impersonate people or brands you know and use themes that require urgent attention, such as missed deliveries, account suspensions and security alerts.

 4) Be cautious of phishing attempts: Be vigilant about emails, phone calls or messages from unknown sources asking for personal information. Avoid clicking on suspicious links or providing sensitive details unless you can verify the legitimacy of the request.

The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

Kurt’s key takeaway

Even though ADT says your home security systems are safe, the fact that hackers got their hands on personal info like emails and addresses is a wake-up call. It’s a reminder that even companies we trust to protect our homes can be vulnerable to cyberattacks. As we wait for more details, it’s important to keep an eye on how ADT handles the situation and stay alert. In today’s connected world, trusting our security providers is crucial, but it’s clear that we need to stay cautious, too.
