You can do this on Windows by opening TeamViewer, moving to Extras and selecting Open Log Files. Go through the connection log to ensure that all remote sessions were started by you from the past week. Make sure that all logins on your local computer are different otherwise, any breach of your TeamViewer information could result in a breach of your other account information as well. If fraudulent activity is found, begin steps to deny charges and protect your account information. Change your TeamViewer password, and monitor the credit card activity of any card that you have used within the TeamViewer system.

If you are a TeamViewer client and your managed service provider has not reached out to you about the recent DoS attack, contact them directly to see if they have knowingly been breached. With information gleaned from the DNS servers, hackers could legitimately gain access to all of the customer information stored within a local account, including full credit card numbers, banking information and saved passwords of TeamViewer clients. A few of the symptoms included starting remote sessions from unknown remote users, unverified and unknown PayPal purchases and client passwords changing for no reason. Hackers were allegedly able to break into many user installs after finding their way into the central servers of the program. The attack was a denial of service attack on the company DNS servers. On June 1st, 2016, TeamViewer was attacked, resulting in a three-hour service outage. The TeamViewer software package is used by many managed service providers to provide remote support to clients. The industry of managed service has recently been attacked through one of these convenient standards. The convenience that comes with standardization also helps the bad guys – they can easily conduct large scale attacks by attacking a single source. Denial of Service (DoS) attacks are becoming more common across all platforms as hackers begin to learn mobile operating systems and industry standard software programs.
