Have a Ubisoft game with UPlay installed on your PC? You are at risk

A major MAJOR security compromise has been found in Ubisofts uplay software which can enable a malicious programmer a back door into your PC. It's a pretty serious security concern and would advise all those with any Ubisoft game installed to remove the plugin in your browser and uninstall any ubisoft product just to be on the safe side.

Essentially, as described here, with the right piece of code any website can call up a Uplay window and from that might be able to slip a program install or launch of their choice onto your PC. Were someone with malevolent intent to inject the code onto a commonly-visited website, they might be able to gain control over any number of PCs – or install keyloggers, viruses and the like, or just plain old wipe your hard drive. The web security expert we chatted to says this could even occur via an email link, making this exploit a phisher’s dream if it’s as a bad as it sounds.

Says the expert we spoke to, “you could click on a weblink, thinking you were visiting the BBC News Website from a friendly list of bookmarks. Except it’d also install a program via UBISoft’s DRM plugin which wiped your hard drive. It is a genuine threat. All it would take is an exploited wordpress, say.”

But I come here not to sensationalise, but to warn. With news of this backdoor spreading like wildfire and proof of concept code already out there, there’s a very real chance that someone will try to achieve something unpleasant with it before Ubisoft can shut it down. That’s presuming it is what it appears to be, of course – this may turn out to be an exaggeration, especially as the internet does so love to mock Ubi’s notorious DRM, but so far the evidence very much points to this being as dangerous as it sounds. I’ve contacted Ubisoft for comment and will update as and when we know more. There’s been no response as yet, and other sites are reporting similar silence.

The fault does appear to specifically lie with a browser plugin Uplay installs rather than Uplay itself, so remove that from your Firefox/Chrome/IE/etc extensions as a priority, but I’m erring on the side of extreme caution and advocating the removal of anything associated with Uplay until this apparent threat is dealt with. Here’s how to locate and disable the errant plugin:


Firefox:
Tools – Add-ons – Plugins – Disable the Uplay and Uplay PC Hub plugins

Chrome:
Visit about:plugins and disable

Opera:
Settings – Preferences – Advanced – Downloads – Search “Uplay”, delete

(Via Revisor on our forums).

Contrary to what some parts of the web are currently screaming, this is not a rookit – it’s an exploit in a browser extension. Alas, the vast majority of folk with said browser extension will have been hitherto unaware that Uplay had installed it.

You can find the games which apparently include the exploit listed below. If you have any of them on PC, I would urge you to uninstall them and any Uplay applications as soon possible as a precautionary measure. If you have any of these games on your PC, you can also see the apparent exploit harmlessly in action with the link here.

We’ve tested with a PC that has never had Uplay installed on it. The exploit didn’t work at all. After installing Uplay alone, immediately the test link did indeed work, calling up the Uplay window, and then with that, booting the Windows Calculator. After uninstalling Uplay, the exploit once again didn’t work.

Calculator’s hardly scary of course, but if someone could use the exploit to slip another program onto your PC or run command lines, anything could happen. Frightening – even if there is still something of a question mark over exactly what level of access a nasty soul could go on to achieve. Additionally, this software would appear to allow Ubisoft to monitor PCs running Uplay, but again let’s wait for more details before any hammers of judgement are wielded.

It appears versions of some of these games are Uplay-free and thus in theory safe, but again it may be better to be paranoid than sorry. You can always reinstall later, right? I’d also urge you to check your list of installed programs in Windows, just in case an old install of the Uplay launcher/plugin is hanging around despite your having previously uninstalled any games that used it.

Here’s the list of titles known to be affected:

Assassin’s Creed II
Assassin’s Creed: Brotherhood
Assassin’s Creed: Project Legacy
Assassin’s Creed Revelations
Assassin’s Creed III
Beowulf: The Game
Brothers in Arms: Furious 4
Call of Juarez: The Cartel
Driver: San Francisco
Heroes of Might and Magic VI
Just Dance 3
Prince of Persia: The Forgotten Sands
Pure Football
R.U.S.E.
Shaun White Skateboarding
Silent Hunter 5: Battle of the Atlantic
The Settlers 7: Paths to a Kingdom
Tom Clancy’s H.A.W.X. 2
Tom Clancy’s Ghost Recon: Future Soldier
Tom Clancy’s Splinter Cell: Conviction
Your Shape: Fitness Evolved

I’m not at all certain that list is complete, given other games are known to use Uplay – From Dust, for instance. Check your program installs and browser extensions/plugins for any trace of it regardless – it might be there from an older install even though the game that carried it is no longer on your PC.

Again, more news as we have it.

Ahh Ubisoft, you've gotta love their anti piracy methods which screw over everyone except the pirates.

Thanks for the heads up though.

Yeah, thanks OP for the heads up. Thankfully, the only Ubisoft game I have is unaffected (Anno 2070).

I noticed. I played some driver just now and it was updating itself. Fair play for fast response.

I never buy PC Ubisoft games anyway. Shame for actual customers but at least it will show some of Ubisofts incompetence when it comes to the PC market at this point. All this DRM for games you can pirate anyway is ridiculous.

It is not really drm problem... It was a security hole in its software. It could happen to any company. Thought I guess everything goes if you want throw a rock at them.
