what is ocsp.digicert.com



I recently had a case where both of the browsers on my PC (FF and Edge) kept trying to make an outbound connection to ocsp.digicert.com. Webroot didn’t flag it as a problem, but I also run Malwarebytes, which blocked it. Uninstalling/reinstalling FF didn’t help. I had to restore my PC to a restore point made a week earlier to get rid of the constant outbound connection attempts.

Afterwards, I also found that Malwarebytes wouldn’t scan my computer. I would start a scan and it would stop 1-2 seconds later with a «clean PC» report. I reinstalled MWB and it seems to work ok now.

Just to be on the safe side, I also reinslatted Webroot, but I’m a little disappointed that it didn’t catch any problems — assuming I had a problem.

What is ocsp.digicert.com and is it something bad?

Welcome to the Communitgy Forums.

From what I can see from my research we have a conundrum here as on the one hand OCSP (Online Certificate Status Protocol) is one of two common schemes for maintaining the security of a server and other network resources. The other, older method, which OCSP has superseded in some scenarios, is known as Certificate Revocation List (CRL).

But on the other hand there is apparently a malicious side to all of this as Ocsp.digicert.com is apparently a dangerous domain associated with spam activities, that usually infects Chrome, Firefox and IE with installation of free software & adware.

Now this is what we know in the Community as a PUA or Potentially Unwanted Application. This one apprently constantly pops up when you open your start page or click links on webpage or do searching on Google. In most cases, it opens new tabs to display bogus software update recommendations or spam virus removal warning, and that the the downloads promoted by ocsp.digicert.com are all ad-support software.

Often they are installed intentionally by you the user as browser add-ons for various tasks such as quick search tools. But they also come with the result of added annoying pop-ups and ads. Other times they ‘piggy back’ with other software that you installed, or try to ‘sneak’ onto your system entirely.

The key to avoiding them is to make sure that when downloading apps one does so from the author’s own website or one that they have recommended, and not 3rd party downloading site.

WSA does detect and remove many PUA’s, and more are being added, but WSA does not detect all of them. A simple browser add-on with PUA behaviour that is easy to identify and easy to remove is not likely to be detected and removed by WSA. Those that are intentionally difficult to locate and remove are. Please see THIS LINK for more information regarding Webroot’s stance on these annoying programs.

To make sure that your WSA is checking for PUA’s with the best proficiently, it sometimes helps to reset the PUA detection within WSA’s settings. For PUA’s that had previously been scanned and determined to be OK, but have since been added to detection/removal, you may want to complete the following steps:

• Open Webroot SecureAnywhere
• Click on ‘Advanced Settings’ from the top right
• Select ‘Scan Settings’ from the left side
• Unselect the option “Detect Potentially Unwanted Applications”
• Click on the Save button (you may have to enter in a CAPTCHA)
• Reselect the option to “Detect Potentially Unwanted Applications”
• Click on the Save button
• Run another scan with Webroot and remove any items that get detected.

And if that does not work or you do not feel technically capable then the best thing to do is to Open a Support Ticket & ask Webroot Support to take a look and remove these for you. There is NO CHARGE for this for valid WSA license holder.

Куда и для чего передает данные Windows 10? Конечные точки подключения системы

В 2015 году мы опубликовали статью Конфиденциальность в Windows 10, чтобы подчеркнуть основные проблемы конфиденциальности системы, в частности невозможность отключить сбор телеметрических данных через пользовательский интерфейс.

Из-за проблем с конфиденциальностью Windows 10 Microsoft подверглась жесткой критике со стороны государственных учреждений в различных странах, в частности во Франции и в Нидерландах. С выходом Windows 10 сразу стало появляться множество инструментов защиты приватности, например O&O ShutUp10 и Blackbird, которые обещают ограничить Microsoft доступ к персональным данным.

У пользователей и системных администраторов Windows всегда остается возможность заблокировать конечные точки, чтобы соединения для передачи данных даже не устанавливались. Данный метод требует расширенного тестирования, потому что при блокировке соединения может нарушиться критически важная функциональность.

Если вы блокируете конечные точки службы обновления Windows, тогда не удивляйтесь, что система перестанет автоматически обновляться.

Стандартные системы Windows 10 выполняют огромное число подключения в автоматическом режиме для различных нужд. Windows 10 постоянно проверяет обновления, проверяет файлы в рамках сканирований Защитника Windows или передает телеметрические данные на сервера Microsoft.

В то время, как некоторые подключения требуются для нормальной работы системы, другие соединения можно спокойно отключить без существенного влияния на функциональность. Особенно это актуально, если какая-либо функция не используется в системе.

Microsoft опубликовала контрольный список конечных точек подключения Windows 10. Список конечных точек для потребительских версий доступен для Windows 10 версий 1709 и 1803, а список для Windows 10 Корпоративная доступен для версии 1709.

Конечные точки подключения для выпусков Windows 10 версии 1803

Ниже приведен список конечных точек подключения Windows 10 версии 1803 для выпусков, отличных от Windows 10 Корпоративная:

What is the OCSP signing cert and key? Who should issue it?

OCSP responder: An authoritative source for certificate revocation status (see [RFC3280] section 3.3). The resource guard that validates a certificate chain and contacts an OCSP responder to request certificate status.

Why is FF in Kali making requests to ocsp.digicert.com?

Warning -> n00b here!

For some time now I am learning the tools for pen-testing but I am still complete n00b. I have installed Metasplitable2 in another computer on local network and I am running Kali as VM on my computer. So I have started BurpSuite to capture traffic to :8180/admin/ on Metaspoitable2. But to my surprise I saw (apart from the expected traffic) POST requests to ocsp.digicert.com. My Kali installation is default (no new SW installed). So my question is: why is kali browser making POST requests to ocsp.digicert.com. Is this normal?

Solution:

This is perfectly normal. ocsp.digicert.com is the server used to verify if an SSL certificate issued by DigiCert got revoked. This is done using the OCSP protocol.

For example the certificates for mozilla.org or addons.mozilla.org are currently issued by DigiCert. This means it will likely check at startup for extension updates and/or browser updates by using HTTPS and will in this context check that the certificates for these domains were not revoked.

What is the OCSP signing cert and key? Who should issue it?

What is the OCSP signing cert and key? Who should issue it?

So, if I have this:

• Example Root Certificate Authority
• Example Intermediate Certificate Authority
• *.example.com (any domain)

I have setup the OCSP for the domain cert only, so the OCSP url is http://ocsp.example.com.

Now, I learnt to run an OCSP server with openssl :

127.0.0.5 points to ocsp.example.com

Now in that command, I learnt that those two are ocsp signing certs and keys:

Now, the next question is what is the OCSP signing certificate and key? Who should issue it?

Finally, these are the questions, I have setup OCSP for the domain cert only, so let me get appropriate instructions for it:

• What should be the -CA option? Should it be the ROOT or the INTERMEDIATE?
• What is the OCSP signing certificate and key, and who should issue it? (And if you can help me, please also let me know how to issue it using OpenSSL)

Solution:

Single OCSP server can provide OCSP services for multiple CAs. To distinguish the target CA the incoming request is for, OCSP implements a revocation profile (or configuration) where CA name ID or key ID (later is preferred) is used as profile identifier. And for each profile you need a Signing certificate issued by same CA as referenced by profile identifier.

In your example, you have two CAs for which you may want to create OCSP revocation profiles:

• Root CA:

where ocsp_sig_root.crt is the OCSP signing certificate signed by root CA (AKI extension in signing cert MUST match SKI in root.crt file). ocsp_sig_root.key is a key associated with ocsp_sig_root.crt .

• Intermediate CA:

where ocsp_sig_subca.crt is the OCSP signing certificate signed by intermediate CA (AKI extension in signing cert MUST match SKI in subca.crt file). ocsp_sig_subca.key is a key associated with ocsp_sig_subca.crt . You most likely will want only this. There is very little value in implementing OCSP for root CAs since their cert issuance/revocation is extremely low and CRL is more efficient.

That is, OCSP will have separate signing certificate for each CA the OCSP serves.

Recording Controller shows ocsp digicert and jibberish in body data

Can anyone please help me, I see ocsp.digicert.com in IP name and jibberish in Body data when I record script from HTTP Test Script Recorder Can someone please guide me? enter image description here

Solution:

It's an endpoint for Online Certificate Status Protocol, I don't think you should be including it into your recording or test execution scope

If you create a test plan from the Recording Template the HTTP(S) Test Script Recorder comes with some pre-populated URL filters to exclude from recording:



the stuff like Windows Update, Google Analytics, and so on should be excluded because it will create extra requests which don't have anything in common with the application under test.

So I would recommend adding an entry to exclude this URL from recording, the relevant regular expression would be something like:

if you have some recorded HTTP Request samplers and you're unwilling to re-record — just delete them from the test plan.

1.3 Overview

The Online Certificate Status Protocol (OCSP), defined in [RFC2560] , provides a mechanism, in lieu of or as a supplement to checking against a periodic certificate revocation list (CRL) , to obtain timely information regarding the revocation status of a certificate (see [RFC3280] section 3.3). OCSP enables applications to determine the (revocation) state of an identified X.509 certificate (see [X509] ). The Lightweight Online Certificate Status Protocol (OCSP) Profile for High-Volume Environments ( [RFC5019] ) provides a profile of OCSP that specifies a subset of the functionality of the complete OCSP defined in [RFC2560]. This protocol specifies the data that needs to be exchanged between an application that checks the status of a certificate and the responder that provides the status.

OCSP is a component of a public key infrastructure (PKI) . A PKI consists of a system of digital certificates, certification authorities (CAs) , and other registration authorities (RAs) that verify and authenticate the validity of each party involved in an electronic transaction through the use of public key cryptography.

The certificate status received as a result of using OCSP is known as a response from an OCSP responder. The OCSP request /response process involves a number of different machines (or functions that might be hosted on the same machine), as indicated in Figure 1.



Figure 1: Response from an OCSP

In the preceding figure, the principal components are as follows:

CA: The CA that provides certificate status information to the OCSP responder through the use of CRLs.

Relying party (RP) : The resource guard that validates a certificate chain and contacts an OCSP responder to request certificate status.

OCSP responder: An authoritative source for certificate revocation status (see [RFC3280] section 3.3). The protocols and data structures used for OCSP are defined in section 2.2 . The connection over which OCSP is conducted is shown in the preceding figure as a solid bold horizontal line.
