Samsung has confirmed that its U.S. data servers were subject to a breach from an “unauthorized third party” in late July, which has left customer data including personal demographic and contact info potentially exposed.

The brand began notifying customers of the data breach on Friday, ensuring that no Social Security numbers or credit and debit card numbers were taken; however, other identification data, including, names, contact and demographic information, date of birth, and product registration information were accessed by the hacker.

Samsung added that consumer devices and accounts not affected were not affected by the breach and customers should not have to change their passwords or take any actions to secure their products or services.

However, Android Central noted it might be a good idea to get a free annual credit report from Equifax, Experian, or TransUnion. Additionally, Samsung has said consumers should keep a closer eye on their accounts for unusual activity and to the cautious of phishing emails

Notably, Samsung claims it became aware of the cyberattack on August 4 but did not make details about the indecent public until September 2. The brand said in a statement that it has been “engaged a leading outside cybersecurity firm and are coordinating with law enforcement.”

Information about the breach can also be found on Samsung’s Security Response Center.
