Analysis OSSProxy MarketScore OpinionSpy Adware/PUP/Trojan/Malware comScore vs Nielsen

A few days back one of our Virus/Malware file submission sites received close to a hundred executables from two IP addresses over an hour period for comScore, Inc related samples running AV detection scans against each file. This activity flagged some interest at first because the binary files were for various Operating Systems such as Linux ELF and MAC OSX and various Windows exectuables with different creation dates going all the way back to 2010. Was this comScore submitting its own files for analysis or security researchers?

The scan results for all the Windows variants conclusively pointing to Adware or clean with virtually no detection for the OSX or ELF binaries with the exception of a few clean and a few trojan/backdoor results. Macs and Linux users are usually not the targets of malware writers as their targets are usually just of the masses for monetary gain. A quick Internet search revealed that a few Mac security sites were linking the OSX files as an OpinionSpy trojan backdoor which meant it was time to fire up some VMs!

Immediately it was apparent what was happening, Mac users aren’t used to dealing with Adware and when they install a program there usually isn’t usually much of a user agreement they have to read and accept. The Mac community may think it is rather progressive but to a lot of PC users they come off as unjustifiably snobby and self righteous with a Virus and malware free Operating System hubris, they may have a case. Point of fact, Trojan.Spyware.OpinionSpy which PC users know as annoying Adware and gradually learned over time it isn’t a good idea to install suspect applications.

Upon loading one of the Mac binaries a user agreement was presented which detailed that this software will track your Internet behavior and send it back to its’ makers. This is essentially the same type of agreement that TV watchers enter into when chosen to be part of the Nielsen Ratings programs. Nielsen would be seen as more prestigious as they select only a limited amount of users to send their custom TV watching and tracking box to. The obvious difference being that if you decide you don’t want your watching habits going to Nielsen you can disconnect the box and walk away, uninstalling software on the other hand must be a tasking endeavor for someone.


After installation there is a toolbar on the browser and there is network traffic with a custom OSSProxy UA string sending and receiving data from and The software uninstalled rather easily and the network traffic stopped, this was the same for the Windows executables which had some annoying surveys and pop ups but nothing even remotely malicious in nature. This software strongly falls into the realm of adware/behavior tracking, the benefit of installing this software is that you may earn a few dollars or prizes for completely surveys.

The references to it being classified as spyware or a backdoor/trojan are false legally and Internet security wise. By accepting the user agreement you are allowing the software to update itself which can lead to more adware on your system. The company that pushes the various marketing and survey taking out is an A+ BBB rated billion dollar publicly traded corporation. They are not spawning reverse shells and taking over your Macs and PCs, one Mac site even claimed they found the hidden site publishing the size of their “botnet” which one can only find amusing. Wonder if the FBI knows how to work the Google, “largest malware botnets in the world.” Go get them! lol

There is something else that is rather amusing, Symantec did a write up in 2007 claiming that MarketScore (a Windows version of the software) was a type of Spyware and left it published apparently forgetting that they now support and scan the companies sites.

Maybe they should of pulled this before taking their money:

Money changes everything:


Commercial Infrastructure

comScore owns thousands of IP addresses that are rotated through the resolution for and which they have owned and used for over ten years now. If comScore’s software was even remotely malicious or illegal you’d see something similar to this on their website overnight. The FBI can seize any commercial domain name pretty much at will now if there is any proof of illegal activity or warranting of an investigation.
