    Teamviewer Possibly Hacked


    TeamViewer denies hack after PCs hijacked, PayPal accounts drained


    Updated TeamViewer users say their computers were hijacked and bank accounts emptied all while the software company's systems mysteriously fell offline. TeamViewer denies it has been hacked.

    In the past 24 hours, we've seen a spike in complaints from people who say their PCs, Macs and servers were taken over via the widely used remote-control tool on their machines. Even users with strong passwords and two-factor authentication enabled on their TeamViewer accounts say they were hit.
    It appears miscreants gained control of victims' TeamViewer web accounts, and used those to connect into computers, where they seized web browsers to empty PayPal accounts, access webmail, and order stuff from Amazon and eBay.

    Time to use the Whitelist feature and 2-factor authentication.

    Unfortunately 2-factor authentication doesn't help, users have reported that they have been a victim of this too with 2-factor enabled.

    My source is the best Dutch tech site called Tweakers:
    Gebruikers klagen over diefstal via TeamViewer-software - IT Pro - Nieuws - Tweakers
    Ook gebruikers met tweetrapsauthenticatie en degelijke wachtwoorden voor hun TeamViewer-account zijn slachtoffer geworden.
    Translation:
    Even users with 2-factor authentication and strong passwords for their TeamViewer-account are victim.

    Not good. Wonder how they get past that?

    It looks like TeamViewer has made changes, they're introducing 2 things for better security. This has come public in an open letter to customers.

    1. Trusted Devices: this function makes that the user must mark a new device as trusted device when someone wants to login for the first time. The user can mark a device as trusted by clicking on an automatic generated link in an e-mail.

    2. Data integrity: this functions looks for unusual behavior. Unusual behavior can occur with for example login attempts from unknown IP's. If the system detects any unusual behavior then the password will be resetted and the user will receive instructions for how to reconfigure their passwords.


    TeamViewer says that the cause of the problem is from databreaches of the hacks from LinkedIn, Tumblr & MySpace wherein credentials have been stolen.

    Thanks axe0. I had added a link for that to the first post, but not described it.

    Interestingly enough, I think that the data breaches coupled with re-use of passwords is probably the real issue, (usually is), and NOT Teamviewer. Still, it's good to see these additional security measures in place. It's unfortunate for them, that now they will have to "clean the tarnish" off from this episode.

    I find that restriction particularly irksome (although I can't think of a better solution). I would have thought that someone who uses TeamViewer would be exactly the type of person who travels a lot and logs in from different IP's as you'd hardly use TeamViewer to connect from your living room PC to the one in your garage.

    It isn't just them of course. I got blocked by one of my gmail accounts recently for forgetting my password in the wrong country. They told me to go home and try logging on from a known IP address again bless them.

    Oh I really am not and it is absolutely true story (although it was my wifes email not mine if I must be 100% accurate and it was my fault I didn't remember the password as I wasn't really listening).

    I felt like they were joking with me though. Go to a different country to log on? Madness.

    Not an impossible situation, someone has/had used the last parts of my first and last name to create a User. No way to find out. He/She must have had access to the site's database to learn the information.
