Certificate Authority Subordinate MiTMs Their Network

Q: Certificate Authority Subordinate MiTMs Their Network

CNNIC, a certificate authority for the Chinese Government, issued a trusted subordinate (intermediary) certificate to MCS Holdings. This allowed MCS Holding to issue and use a SSL/TLS certificate for any website, but it was expected it would only be used on websites they owned. Instead, it was used internally (and stored in plaintext) to perform a man in the middle attack against all traffic within their company. 

On Friday, March 20th, we became aware of unauthorized digital certificates for several Google domains. The certificates were issued by an intermediate certificate authority apparently held by a company called MCS Holdings. This intermediate certificate was issued by CNNIC. 
CNNIC is included in all major root stores and so the misissued certificates would be trusted by almost all browsers and operating systems. Chrome on Windows, OS X, and Linux, ChromeOS, and Firefox 33 and greater would have rejected these certificates because of public-key pinning, although misissued certificates for other sites likely exist.
We promptly alerted CNNIC and other major browsers about the incident, and we blocked the MCS Holdings certificate in Chrome with a CRLSet push. CNNIC responded on the 22nd to explain that they had contracted with MCS Holdings on the basis that MCS would only issue certificates for domains that they had registered. However, rather than keep the private key in a suitable HSM, MCS installed it in a man-in-the-middle proxy. These devices intercept secure connections by masquerading as the intended destination and are sometimes used by companies to intercept their employees’ secure traffic for monitoring or legal reasons. The employees’ computers normally have to be configured to trust a proxy for it to be able to do this. However, in this case, the presumed proxy was given the full authority of a public CA, which is a serious breach of the CA system. This situation is similar to a failure by ANSSI in 2013.
This explanation is congruent with the facts. However, CNNIC still delegated their substantial authority to an organization that was not fit to hold it. 
Chrome users do not need to take any action to be protected by the CRLSet updates. We have no indication of abuse and we are not suggesting that people change passwords or take other action. At this time we are considering what further actions are appropriate.

Preferred Solution: Certificate Authority Subordinate MiTMs Their Network

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)



I am trying to resolve an issue where multiple client computers in the organisation are using an internally deployed Root CA certificate (before my time and no longer required) to sign the end entity certificate for external websites, google.co.uk
for example. All SSL sites appeared to be affected by this.

However this is not the case as sub domains of sites with issues show the correct cert chain, the below is for mail.google.com

Removing or untrusting this root ca cert breaks access to these sites.

I have reset root certs in various ways, removed machines from the domain, applied no GPOs, manually updated CRL and pulled down updated certs with rootsupd.exe.
It always attempts to use this rouge CA cert to sign the websites cert.

Any assistance would be much appreciated.

I am trying to install CA root certificate on Windows 7, IE 9.
Encounter error: "Untrusted Certificate".  "This certificate cannot be verified up to a trusted certificate authority."
I have tried to install the certificate to Trusted Root Certificate Authorities->local computer and import was successful. BUT on IE->Internet Options->Certificate->Trusted Root Certificate Authorities, I am unable to find this root CA on
the list.
On mmc->Certificates->Trusted Root Certificate Authorities->certificates, I am able to view this root CA.
I then restarted the IE and view the ssl site again but failed too, "Untrusted Certificate".
Anyone, any idea ?

A:Unable to Install Root CA Certificate - Certificate cannot be verified up to a trusted certificate authority.

May the following workarounds work for you:
Workaround 1:
Modify the Windows settings to allow the Update Root Certificate feature to update the root certificates automatically. For details, see the following Microsoft TechNet article:
Certificate Support and Resulting Internet Communication in Windows Server 2008
Workaround 2?
If the Update Root Certificate feature cannot automatically update the root certificates, you may contact the website vender to see if there is a hotfix can fix the issue.

Through the web interface in the browser IE11 is impossible to request user certificate - when you press "submit" button for certificate request, nothing happens.

At another PC with IE9 all works fine - i can submit request and recive certificate from CA

I installed all available updates for Windows and IE11, but its not resolve problem. I tryed to add CA to Trusted Sites, to set IE11 security settings to minimal level - it not helps 

I found article which describes this problem https://support.microsoft.com/en-us/kb/2988411 , but I have all necessary updates are installed on IE11, including those referred to in article.

Hi guys,

I'm having a problem connecting my windows phone to an enterprise wifi network. The network uses peap protocol. As windows phones don't bypass certificate validation, I'm not able to connect to that network. The only solution for me is to get the certificate that the server uses and install it on my phone.

My question is : How to find the certificate which my college network uses by connecting it to my laptop? Some said that ticking mark beside 'Validate server certificate' gives success but unfortunately my laptop is not connecting if I'm removing the tick mark.

So is there any way to find the certificate which my college wifi network uses?

PS : I can't contact the IT department for this for some reasons so, any answers other than this are greatly appreciated.

Hint: start first by reading post #7 in that thread, and you might be able to lookup things like protocols, e.g. TCP in Wikipedia here - Note: the other protocols in the right-hand panel, particularly to which layer each protocol belongs.

Note: The link in post #7 is not stale. It requires you to visit the homepage of SANS:

I received the following error message: "Windows unable to find a certificate to log you onto the network <NetworkName>

I am attempting to get an aunt's laptop connected to my network to troubleshoot a few problems with it and when attempting to connect to my home network I received the above error. In the network list I see my network just fine but its saying "Validating identity" next to the network name.

Her laptop:

I have already updated the wireless driver for the laptop, at first thinking that was the problem. My router (Netgear WNR 3500) does have encryption on (WPA2-PSK) and I'm seeing that the only option for encryption in the Windows Network setup is WPA-PSK. Could this be the issue?

If not, any thoughts on what the issue is and how to resolve?

A:Unable to find certificate to log onto network?

Since I have to guess, I think you are attempting to attempt to a LAN through a wireless access point. Sounds more like you have it set to use a RADIUS server for authentication, rather than Pre Shared Key.

If your only encryption option availiable is WPA-PSK, then that is what you should use. Not WPA2, but WPA.

If this does not help, you will need to disclose the physical setup of your network.

I currently connect to our office server by way of an installed certificate onto my PC and then using a VPN which is first established before I can map a shared drive and work with the files stores there.

Is there a easier way of doing this ? ideally looking for a way of keeping the shortcut on my desktop and having the ability to drop and drag files between the two without having to connect and then disconnect a VPN.

This possible at all?


A:Mapping a network drive using certificate but not a VPN - possible?

The only way to use a certificate, is if you are using a Domain. VPN is for remote file servers, not in house. If this is an issue with a remote share, then the troubleshooting needs to be done there, not at the other end.

your wireless router is not setup for certificate security.


That's caused by improperly setting the encryption on the Router to WPA-RADIUS instead of WPA-PSK on the client. The router and the client are both trying to find a RADIUS server with which to authenticate. Since you
don't have one, it complains using Microsoft technobabble. Change the
encryption to WPA-PSK (pre-shared key) on both ends.

I recently bought two Belkin F5D7320 (v8000, latest firmware) Wireless G routers, and I'm having a very strange problem. I set one up to use WPA-PSK. Using my laptop (running XP Pro SP2), I find the SSID (using the Windows wireless utility), then I double-click on the network. I enter in my WPA key, just like I always would, and it goes through the process of acquiring a network address and all of that, but as it's doing that, I get a bubble alert in the system tray which says "Windows was unable to find a certificate to log you on to the network (SSID)."

The connection seems to still work, though; just I get this message. I have tried a few different laptops, and they get the same message. I have other wireless routers secured with WPA, and I have never gotten that message before using the new Belkin. Out of curiosity, I opened up the second identical Belkin router, applied the same WPA settings, and it seemed to do the exact same thing.

I seriously doubt it's a laptop issue, as I have used the same procedure that I have used countless times to connect to WPA-secured networks, and I have also tried this on a few different laptops, with the same result.

I searched for this message, and people almost immediately suggest that it means either the router or computer are configured to use a Radius server. Well, neither are, as far as I can tell. In fact, here are the settings for my router:

I tried to change my network settings from WPA2 to WEP last night and like an ***** I screwed it up. I only wanted to change it over temporarily so I could access the wireless network with another device that isn't compatible with WPA2. I ended up having to restore the Linksys router to its default settings. I then tried to recreate the settings it had before with WPA2 before I messed it up. It was on WPA2-Personal, AES, and I changed the network SSID and passwords back from default. Very basic. I didn't set the router up myself originally, though, so there must be something I'm missing.

I am able to connect via Ethernet cable, but when I try going wireless (on both Windows laptops, one XP and one Vista) I get a message saying "Windows was unable to find a certificate to log you on to the network [my SSID]". Most of the searches I ran on Google had people suggesting that I uncheck "Enable IEEE 802.1x authentication" in the laptop's wireless Authentication settings, but that is already unchecked.

Besides, shouldn't the fix have to do with something in the router settings since the wireless was working before I mucked around with the router? The laptop settings remain unchanged from the when wireless used to work so they should be okay, right?

2) They use POP 995 w/ SSL & SMTP 465 w/ SSL to pop.secureserver.net & smtpout.secureserver.net repsectively

I have some Windows 7 systems which have not run Windows Updates for many years, and cannot due to regulatory reasons.   We rely upon Windows to automatically update the Trusted Root Certificate store whenever we browse to a web site/web service
that uses a certificate the system doesn't recognize. 
Sometime recently, the Trusted Root Certificate Store no longer updates automatically.  The Windows Event Log shows an error stating that the certificates cannot be downloaded from:
http : // ctldl.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab
If we browse to this location manually, the cab file contains an invalid Microsoft certificate. 

This was also an issue in Sept 2018.  At that time, the certificate had expired, and Microsoft eventually updated the certificate to resolve the issue.   This time, the certificate does not appear to have expired.  Why is the certificate
invalid this time, and can Microsoft fix it again?

Really confusing one here. Since this weekend (16/17 July) we have started getting Certificate errors on some sites and applications. This seems to be due to the structure of the URL compared to the "advertised" name IIS is presenting. I'll try
to explain.
I have a site, Website. This is in my domain, domain.com. Therefore the FQDN is website.domain.com. IIS is running and I can access this site through FQDN,NetBIOS or IP address. Good news.
I create a certificate for the server using the FQDN as the subject, I add the Netbios and IP addresses in the Subject Alternate Names and Bind this to port 443 on the server.
I browse to https://website and all is good. I browse to https://website.domain.com I get a certificate error. Checking the certificate, everything is fine, no errors, chain is trusted. open Chrome and do the same, I get that the certificate website.domain.com
is being presented by Website and may not be the site I want.
Using either URL has never been a problem until this weekend, but it seems that IE/Windows/IIS is not liking any URL that is not EXACTLY what IIS is presenting. so my questions are:-
Is anyone else finding this?
Can we issue a certificate that covers all possible DNS resolutions for a site?
How do I control WHAT IIS advertises itself as?
SO far this has affected two major systems on our network and I can see that more will arise, so any help would be appreciated.

for a normal-user way to do it.  I think it used to be possible in Internet Explorer, but this might have been 6.x or even earlier.  Or even

We have a problem where we encrypted files using EFS, however we can't access or decrypt these files now.

We have the certificate in the certmgr.msc but we do see that the key is missing.

I have reproduced this on another computer and was able to run certutil -repairstore -user MY "Serial Number" which worked in repairing the store and files was decryptable again.

However on the machine that encrypted the files that we need to access this is not the case as there is a popup asking for your Smart Card.

We are not using Smart Cards at all, and have had a look at the following article regarding this issue, but the hotfix didn't work: https://support.microsoft.com/en-us/kb/2955631

I have software that can remove the encryption but will require the .pfx file, which can't be exported as the certstore doesn't show that it still has this.

It is a self signed certificate generated by Windows, so I can't request a new one using the CA.

Thanks for your help in advance.

Having some fun with a windows 7 setup of DirectAccess, have it configured to use ECC certificates on the client for the IPSec authentication, which was working brilliantly, we even have it loaded up behind a Citrix Netscaler to do SSL offloading of the
HTTPS tunnel encryption. But when trying to get Client Preauthentication working, we hit a snag, it seems that the NetScalers dont support ECC certificates, which is a pain, but something we thought we could work around by using an RSA certificate on the client
to performed the pre-authentication (as shown here https://directaccess.richardhicks.com/2016/05/10/directaccess-ip-https-preauthentication-using-citrix-netscaler/).
So we have three CA's, CA1/2 issue RSA certs and CA3 is setup to do the ECC ones, so nice separation of the chains.
So we have our Cert chain for RSA loaded into the load balancer and a new cert issued to the client from CA1... But, every time the client connects to the server (LB) we see the handshake taking place, the server sends a list of its DNs (CA1/2) (https://blogs.msdn.microsoft.com/kaushal/2015/05/27/client-certificate-authentication/)
to the client, but then the client looks in its store, picks out the ECC certificate (issued from CA3) and fails to authenticate saying no suitable certificate can be found, its like its not even looking at the RSA one at all.
So, thinking something was wrong with the way the LB was asking for client authentication, I tried deleting the ECC cert a... Read more

Every time I installed the certificate, it is working and allow me access to the website with relevance ID. However, the installed certificate will be missing if I continue to install with another certificate. The way I install the certificate is just double click on the PKF certificate that provided by the website admin, then kept click on the next button until its finish the installation steps. All the certificates will install to "Personal" certificate store folder, but the problem is only one certificate will remain.

I ever try to import all the certificate with using windows certificate manager, is allow me to import all the certificates and able to let me access to the website with select different certificate to login with selected account ID.

The motioned problem PC is running on Windows XP SP3 with latest update. And the using internet explorer is version 8 with latest update as well.

I had try to reset the Internet Explorer to default, but is not working so, appreciate is anyone can guide me to solve this problem

A:PKF certificate missing after new certificate was installed

Under "Content" in Internet Options, are all your certificates there? Mine are. Either your Admin. or the issuer should have your answer. Some PKFs are not compatible with all OSs or Browsers. Try downloading certificates to Firefox or Chrome and see if that works.

Running Windows XP Service Pack 3.

I set this up last night on my own wireless network and it worked fine. I have brought it to another location and I'm getting this error when attempting to log on wirelessly. Both routers are running the same type encryption with the same key.

"windows is unable to find a certificate to log you on to the network"

When the above error disappears, I see the list of available networks with the network I just attempted to connect saying "Validating Identity". That message stays there continuously and I have no throughput.

I have verified the time and date on the computer is correct. Other Windows 7 laptops at this location are working fine wirelessly.

I have tried the advice at this location with no luck.

Can anyone tell me what NT Authority\Local Service and NT Authority\Network Service are?

They have both shown up as logins on my Belarc system report and I haven't got a clue as to what they are.


A:What is NT Authority?

From Microsoft.com

"Local Service Account
The Local Service account is a built-in account that has the same level of access to resources and objects as members of the Users group. This limited access helps safeguard the system if individual services or processes are compromised. Services that run as the Local Service account access network resources as a null session without credentials. Be aware that the Local Service account is not supported for the SQL Server or SQL Server Agent services. The actual name of the account is "NT AUTHORITY\Local Service account"."

The Network Service is essentially the same thing but for networking aspects of your machine. The way I understand it, they are local accounts that run background processes but keep your machine more safe should something be compromised.

Hope that helps.

So, there is this computer is having issues with the NT Authority thing with the shutting down along with other various trojans.. This computer also has no anti virus and can't boot up without safe mode because it will auto shutdown. It has AVG but its broken and uh.. won't work. I've ran Ad-Aware, SmitFraudFix for the reappearing annoyances of Brave Sentry and installed a windows patch for the NT authority vulnerability. But now, I still get problems. And I can't find the firewall on it.

...stop it from rebooting my computer when I start disabling svchost?

I have NT service pack one and never upgraded to any others because the first one is giving me enough hassles. It's created docs and hidden folders on C: that Windows can't access and I have to diddle around in DOS to find them.

Which also leads me too - what is the DOS command to reveal hidden files/folders and remove the Read Only property from them?
