Any user can request this unregistration. DLL unregistration, it's possible to run arbitrary scripts bypassing AppLocker and cause mischief. By embedding some JavaScript in the fetched XML, and triggering its execution by requesting a. Smith found that if you give regsvr32 a URL to parse, it will actually fetch the file over HTTP or HTTPS, even via a configured proxy, and process it. s tells regsvr32 to be silent, /n tells it not to use DllRegisterServer, /i passes an optional parameter (our URL) to DLLinstall, /u means we're trying to unregister an object, and scrobj.dll is Microsoft's Script Component Runtime. regsvr32 is part of the operating system and can be used to register and unregister COM script files with the Windows Registry. The magic here is that if you change cmd.exe for any program outside the AppLocker whitelist, bingo: it will start, in theory. Running this tells Windows to fetch an XML file from the internet, which tells it to run cmd.exe. Here's a sample command demonstrating the technique it even fits neatly in a tweet, and verified using an El Reg Windows Enterprise system: It was introduced in Windows 7, and the idea is to keep users on the straight and narrow: stop them from launching non-work-related programs, stop them from running malicious programs or malware-launching scripts, or stop them from running programs that will involve lots of support calls.Ī security researcher called Casey Smith has found that AppLocker's script defenses can be potentially bypassed with a pretty simple command.

A security researcher says he's found a way to potentially bypass the operating system's software whitelist and launch arbitrary scripts.ĪppLocker lets IT admins managing large networks of machines define which applications and scripts users can and can't run and install. In other words, it enables companies to lay off IT staffers to cut costs? "Unfortunately, that's where a lot of IT managers are at," Schuster said, although she noted that many companies are simply cutting through attrition.Video If you're relying on Microsoft's AppLocker to lock down your office or school Windows PCs, then you should check this out. With Windows, companies will have "a single OS that can do the work of seven or eight vendors and require fewer people and fewer resources when managed through Microsoft System Center," she added. Those third-party apps mean more vendors to work with and more hassle," she said. However, I cannot get AppLocker to succesfully restrict a program. It seems like AppLocker would be perfect for this. I would like to restrict access to just about everything else on the operating system (files, programs, etc). On the other hand, "it depends on how the CIO wants to drive costs out of his or her organization. I am trying to set up a user account that can be used to run Windows Media Center. Schuster acknowledged that there are plenty of third-party applications that replicate those features, and at lower upfront cost.

New features available to Windows 7 Enterprise customers include BitLocker to Go, which protects applications stored on portable media such as USB flash drives, and AppLocker, which, through Group Policy, lets administrators decide what apps can be installed on employees' PCs.

Altogether, out of 10 million devices and peripherals, 75% already have drivers carried by Windows 7, another 20% are available now through Windows Update, with the remaining 5% still being worked on by Microsoft. On drivers, Microsoft has now certified 2.8 million unique devices as plug-and-play for Windows 7, she said. "We don't want to randomly break apps simply because of a versioning issue," she said. With Software Restriction Policies, IT professionals could create rules such as 'Trust all content signed by Microsoft,' 'Trust this single executable file,' or 'Trust the file at this path.

But isn't it more prudent for apps that haven't been explicitly rewritten and certified for Windows 7 to be prevented from installing, in case the software misbehaves down the road? Not at all, Schuster said. Windows 7 includes AppLocker, which is an update to Software Restriction Policies, a feature in earlier versions of Windows.
