Reassignment of unique IDs

Hi all,

TeamViewer is constantly working on the best security and service for our customers.

In order to deliver on this pledge, TeamViewer’s team and leading security researchers perform regular threat prevention analysis to identify inconsistent or suspicious behaviour within and beyond our network.

As a result of our continuous prevention analysis, we detected patterns of connection attempts that seem to be at odds with normal TeamViewer usage. As this observation was limited to a small subgroup of endpoints, TeamViewer decided to invalidate and automatically re-assign all TeamViewer IDs within this subgroup.

The precautionary measure has successfully been rolled out to full effect. For a short period of time, some users may experience service degradation, which will be resolved as soon as possible.

Best,
Esther

Re: [Update 2]: Reassignment of unique IDs

Multiple machines in the computer list have (unknown) by their name and can not be connected to....

Is this problem going to fix itself?  Or do I have to reinstall Teamviewer Host on all those remote machines?

Re: [Update 2]: Reassignment of unique IDs

Were a small support company and have been down most of the day, the status page says fixed but i still cant access my clients. This is costing us money and broken SLA's

To check your individual case I recommend to call my colleagues in our Florida office (+1 800 638 0253) or to raise a ticket.

I am sorry for the inconvenience caused.

Re: [Update 2]: Reassignment of unique IDs

Hi @Esther,

There are TONS of people all reporting the same issue as me.  Unable to reach computers with (unknown) by their name in the computer list.  Is Teamviewer aware of this problem and are they working to fix it?  If it is going to require reinstalling Host on the machine, then just say so.  That way your customers can get started on it.  The level of customer support related to this issue has been ATROCIOUS

Re: [Update 2]: Reassignment of unique IDs

Just spoken to American support seems that the client ID's have been or are being changed

Hopefully will just need the end user to read out the new ID will see in the morning. Might have a look at ConnectWise as a backup remote access

Re: TeamViewer ID Keeps Changing

Hej everyone,

I believe I have had this issue before, but was never sure if s/o else had reinstalled TV etc. Today I was DEAD SURE for the first time since I had logged on 3 days ago, and today I couldn't. The ID just jumped from 3xxxxxxxx to 12xxxxxxxx. My customer's server is 2008, and it has 2 physical NIC's, but only one of them is in use. So I don't buy the explanation of the multiple NIC's.

I have read the ENTIRE thread and can agree with everything that you wrote. Especially that a program for remote access should not do this... Have filed a support case and look forward to their response. (as a matter of fact, being a product supporter myself, I am wondering why the TeamViewer guys are not more present here!)

On a side note, I permit myelf some ranting and hope that TV will notice: I have been ben using TV for years and used to be highly satisfied. But that changed with TV13. It seems these guys have forgotten that TV is supposed to be a tool for remote access. Instead, they are trying to pile up new "features" which I don't need. Most notably (or should I say, infamous?) a new UI which techies like me certainly have not requested. Also a nuisance like changed license activation - opposed to what they wrote on the bill, I *had* to to it online and it took me quite some time before I figured that out. So, my advice to the TV guys is to be a bit more conservative when it comes to reliability/stability vs. making money.

Now waiting for the answer from support. Will keep you posted :-)

Re: Reassignment of unique IDs

My organization doesn't have many machines to manage so what we did to retrieve the new Teamviewer IDs was to access the C:\Program Files (x86)\Teamviewer\Version7 path using Windows Explorer. There is a file named "TeamViewer(version #)_Logfile." At the end of the file, look for an entry that states:

"Router Pong Received with following Hops: (IDNumber_1) (IDNumber_2)."

The one on the left, (IDNumber_1), should be the new Teamviewer ID for that computer.

Again, this won't work for everyone. Just wanted to contribute in case it helps anybody. At least for us, it helped for the time being.

I don't know if the ID will revert back to the previous one or not.

Re: TeamViewer ID Keeps Changing

Just happened to me today in the middle of a session. Was connected then became disconnected. When ! went to reconnect it said I was blacklisted and I noticed my ID was completely different and I could not connect to any of our machines. Corporate license Teamviewer 11.

Same, no other solution for me now than to get to each machine in person and get the new ID.

Re: Reassignment of unique IDs

We have some client PCs for which we DO NOT have UNC access, but have physical access.

When we right-clicked and wrote down the ID, it didn't work for us to remote in. Part of me thinks what is being shown might not be the actual ID, or it might be in the process of being changed.

Re: Reassignment of unique IDs- ALL SUPPORT IS DOWN

We discovered that any of our older installs were still offline.  We had to uninstall/reinstall teamviewer in order to get them to show online again.  25+ computers at 5 different locations.  It was the only way we could get it to work again.

Getting this as well. I have certain IDs that are whitelisted to access certain PCs and they all stopped working. Had to whitelist the new IDs. No idea if these new IDs are permanent tho or a bug..

Re: TeamViewer ID Keeps Changing

My ID has just changed by its own yesterday, I had to drive to my office 20KM to check what the heck was going. As much ridiculous as embarassing. I hope you fix this soon. I'm gonna have to install other software because apparently Teamviewer has stopped being reliable.

Man ... this kind of stuff just can't happen on production.

One of my PCs is still offline after outage on July 24th 2018

Hi there

All my machines came back online after yesterday's outage except for one. Is there still a problem somewhere in the system?

Thanks

Hi Max,

I moved your post here as it is related to this issue.

It is likely this is one of the ID's that switched. Can you check the remote side and look for the new ID?

Scotty

Re: One of my PCs is still offline after outage on July 24th 2018

Just had an email from one of the client companys affected, they are asking if this was a security breech and if so do they have to report it to the ICO under GDPR rules....

Gulp now now very worried. Ester do you know if it was a security breech?

Changed ID numbes after crash 24 juli @teamviewer

I'n not able to submit a ticket in your website. My licencekey is being rejected at the automated system, but im a commercial customer since 2014.

I support a group of customers in the agricultural world with it systems and support and also some elderly people. Since yesterday a few systems have a black status unknown in my account computerlist.

Now i sometimes use from my iphone 7+ to enable some features on site by conencting to my own system at my workshop. this one is also unknown. But i found out whats causing this.

In my adress book my teamviewer id for my own system is a 9 digit number beginning with 9. My own computer now had a new id in a 10 digit format beginnin with one. This has happend to more customers of mine.

So i now have to travel to my customers to open up the feeding computers, connect monitor keyboard and mouse to see the new ID numbers. Some are an hour drive from my shop. 

Teamviewer; changeback the id's to the old ones or atleast upgrade my account's numbers from your site. You should have a list from what youve altered.

If im going to take a tour from one day to get from customer to customer, who is going to pay for that?

Re: ID suddenly changed on my computer from 9digit to 10digit and all my contacts and computers (remote) seem to be lost

So the IDs on two of my PCs (on the same ISP and router) were changed.

YOU SHOULD update the IDs in your WAKE ON LAN lists.  I just did.

I've got the same problem. TV is my mail work tool and I couldn't use it yesterday. Some of my client PCs are half across the country. Is this what I'm paying for?

Hello,

the problem is not resolved. All my clients (all connected/assigned to my account and with "simple/direct access") are shown as offline. It seems all of them got new IDs !?!?!?!?!?!

This is a huge problem that needs to be solved!

Re: Reassignment of unique IDs

It's great you're thinking about security but this took our newest remote computer offline and I had to have our attorney drive out to its location and Skype me from it so I could figure out the issue. How about some sort of warning or heads up next time?

Re: Reassignment of unique IDs

Hi Esther,

You've got to be joking?  Reassigned ID's without any forewarning leaving us users with no way of remotely connecting to find out what on earth is going on.  In my working days this kind of action would have resulted in someone being shown the door.  I'm not surprised that your customer base is extremely unhappy.

Dreadful service.

ID Change

Hi

I have a server that is running Server 2012 RE2 and Teamviewer version 13. I need to connect to that server on a daily basis but yesterday the ID changed to a different 9 digit ID and after a restart it changed to a different 10 digit ID. Is the ID going to keep on changing? This is really critical that I need quick and easy access to this server.

unknown clients - cannot use old version or reinstall and update it

Hi. In our company we use an old version of TV, 6.0 After the problem of past days we have a lot of clients with a question mark (?) on it and statu "unknown" (like other users). If I try to reinstall or client than to reconnect it on our account the system says (as usual) than I must update it to the latest version that is 6.0.17222  but tv says that ther was an error and it could not be updated - CTVUpdate failed - CInetDownload::ThreadRun - ErrorSendRequest 12031, Errorcode=12031
Did TV cut-out old version to force to buy new one?

Re: Reassignment of unique IDs

Our company uses TeamViewer to remote into over 300 computers.  We appreciate the need to change the ID for security reasons, but this is causing major issues. We have five different employees that have to remote into these computers for different reasons.  

I personally took the time to enter all the TVIDs into my console, but the other employees hadn't.  Is there a way I could export my list to share with them?

Connection not established

Following the issues Teamviewer has earlier this week, I have found one of my clients impossible to connect to. All of their computers are blue-lit in my list of contacts, and after conversations with the clients themselves they have the app running with the same original ID number (some changed due to TV security) However I get a connection not established messsage whenever i try to connect. I have got them to restart the Teamviewer service, restart their PC's, re-install Teamviewer, all to no avail. Since the outage i have managed to re-establish contact with all but this client. Can anyone help?
