Due to the reported data breach, we are currently enforcing a password reset process for all TeamViewer users with an email address from Yahoo.
Why has my TeamViewer account been blocked?
A TeamViewer account will be blocked whenever no password has been set. This may happen if an error occurs during the account generation process. This may also happen if you add too many devices to your TeamViewer account without confirming them as trusted first. Another possibility is that we have reason to believe your security may be impacted and thus enforced a password reset to protect your digital integrity.
Are there any external data spills that may represent a risk for the use of my TeamViewer account?
Online account credentials are traded on the Dark Web (Yahoo is the latest example). External data spills may represent a risk for you if you reused your account credentials.
What are potential threat scenarios that may arise from a data spill elsewhere?
If cybercriminals manage to get their hands on your email account credentials, they may certainly gain access to your email account. Subsequently, they may run a variety of different malignant scenarios, which are not restricted to the affected email account.
It’s important to be aware that a third party password spill could impact TeamViewer users. A hacker may, for instance, use an email address to set up a TeamViewer account in order to abuse it for criminal intent. In this instance, a confirmation message including an activation link is sent to that particular email account.
If the criminal has access to your email account it means that they can activate the TeamViewer account and use it in your name. It is possible for hackers to do this without your knowledge as they sometimes apply very intricate tactics to veil their doings.
Has TeamViewer been compromised in any way?
Can I do more to add security to my TeamViewer account?
To protect against unauthorized access, we recommend to activate two factor authentication. Additionally, you might want to consider to set up whitelist on your device: The TeamViewer whitelists are a very effective means to determine who can access your machine. In other words: you set up a list and only the parties on that list can access your device. We also recommend to never reuse or share passwords, change passwords regularly, and use password managers.
Are there any supplementary steps I should take?
Email accounts are a common vector to inflict breaches upon you and your cyber integrity. Therefore, we encourage you to quickly change the password to your email account, and make sure it will not be controlled by an unauthorized party. If you use the same password across other services, we recommend that you also change those passwords immediately. Here are some practical suggestions on how to come up with an adequate password.
What should I do if I believe my TeamViewer account has been abused?
If you have questions, please don’t hesitate to contact our support team and submit a ticket. Due to data security regulations any inquiry regarding accounts must be sent from the e-mail address the account is linked to. TeamViewer is subject to extremely strict data privacy laws and regulations. So if you have reason to believe you were the victim of a crime we encourage you to report your case to your local police department.
