Note: Verizon Media is now known as Yahoo.
We’re committed to protecting the security and safety of our users, and we strive to detect and prevent unauthorized access to user accounts by third parties. As part of this effort, Yahoo will now notify you if we strongly suspect that your account may have been targeted by a state-sponsored actor. We’ll provide these specific notifications so that our users can take appropriate measures to protect their accounts and devices in light of these sophisticated attacks.
Our notifications provide targeted users with specific actions they can take to help ensure that their Yahoo accounts are safe and secure. If you receive such a notification from us, here are some of the actions you should take immediately:
We also strongly encourage you to protect yourself outside of your Yahoo account:
It’s important to note that if you receive one of these notifications, it does not necessarily mean that your account has been compromised. Rather, we strongly suspect that you may have been a target of an attack, and want to encourage you to take steps to secure your online presence. In addition, these warnings to our users do not indicate that Yahoo’s internal systems have been compromised in any way.
So how do we know if an attack is state-sponsored? In order to prevent the actors from learning our detection methods, we do not share any details publicly about these attacks. However, rest assured we only send these notifications of suspected attacks by state-sponsored actors when we have a high degree of confidence.
We will continue to refine our detection and notification of state-sponsored threats and remain committed keeping your account safe from unauthorized access.
