Unknown User Agent fragments

 

The main web browser detection work is done based on the User Agent provided by web browsers.

For the most part, between common sense and a Google search or two it's possible to figure out what 90% of the various User Agent fragments mean (and thus what should be displayed for users when they come along).

But every now and again I encounter User Agent fragments that I can't figure out, nor does it seem anyone else on the internet can figure out.

So since I'm regularly looking at them and I want to share the knowledge, I figured this would be a good place to post all the ones that I can't figure out and perhaps someone out there in Internet Land knows what it means or can figure it out.

So, if you're trying to figure out "what does this user agent fragment mean"... then you've come to the right spot. If you can tell me what any of these mean, I'll happily give you credit for it.


Operating Platform/Vendor Fragments

Update: March 2013 - Confirmed that these are Operating Platform/Vendor fragments.

Update 2013/2014: We are continually updating these with new ones.

I have finally satisfied my strict burden of proof regarding these fragments. I now understand and can prove that these are "vendor id" or "OEM id" strings.

Recently, a helpful user contacted me to suggest that the MATBJS string may be related to the GreenBrowser browser, as he had noticed it in his own user agent when using GreenBrowser. I investigated, including installing a copy of it on a virtual machine, but my copy of GreenBrowser didn't come up with the MATBJS string. Since I'd finally gotten in touch with someone who actually had one of these strings in their user agent, I pressed on and asked the helpful soul to search their registry for the string (if they were comfortable doing that!). He did, and found it appeared in a special place in the registry dealing with common OS information.

He sent me a screenshot, here is the relevant part:

Screenshot of Windows Registry showing MATBJS is an OEMID string

You can see "MATBJS" in the "OEMID" key (OEM meaning "Original Equipment Manufacturer"). To me, this confirms that MATBJS and most if not all of the similar strings are also Manufacturer IDs. I had found one or two posts from years ago on online forums which suggested this, but I aim to have the detection on this site be as authoritive as possible, so I wasn't just going to take a guess on it based on one person's opinion on a forum, especially on such a popular fragment. 

Since I hadn't looked at this question in a while, reinvigorated with this bit of information, I then took to searching the web for more hints about the other strings. This is what I have come up with. Note that the strings that end in JS are almost certainly related to the ones that don't and so I have grouped them together.

A big thanks to "Dr. Omni" for contacting me about MATBJS and re-sparking the hunt!

Thanks to Andrew for the "MATP" fragment

This first appeared in February 2012. 

The name implies "Microsoft Store"; I wonder what DMC stands for, perhaps Download Manager?

There is something called Dell Management Console, does it have anything to do with that or is it just a red herring?

Do you know what MS STORE DMC 2.6 means in a User agent string? Contact me.

The obvious guess would be that it's iPhone; but note that they're all on Windows NT with MSIE 8, so it's not that. My guess is that it's either some kind of iPhone add on utility or more likely some kind of IP Phone/handset addition. But which one?!

SRC 2.7.1 E1

This is seen in User Agent strings like:

All the instances of this that I've seen have been for MSIE 7 on Windows XP. I also notice that they're always grouped right next to MS-RTC S which is a part of Microsoft Live Meeting. Perhaps it's something that gets installed at the same time as Live Meeting.

This appears without a version number, typically right at the end of the user agent. For example:

  • Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E; .NET CLR 1.1.4322; Hemit)
  • Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB7.4; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E; .NET CLR 1.1.4322; .NET CLR 2.0.50727; Hemit)
