Microsoft Digital Forensics Tool Leaks Online

A secretive Microsoft utility called Computer Online Forensic Evidence Extractor (COFEE) has leaked online. An automated digital forensics tool for law-enforcement agencies, COFEE isn't available legally to individuals.

"COFEE brings together a number of common digital forensics capabilities into a fast, easy-to-use, automated tool for first responders. And COFEE is being provided—at no charge—to law enforcement around the world," a description of the tool reads.

"With COFEE, law-enforcement agencies without on-the-scene computer-forensics capabilities can now more easily, reliably, and cost-effectively collect volatile live evidence," the description continues. "An officer with even minimal computer experience can be tutored—in less than 10 minutes—to use a preconfigured COFEE device. This enables the officer to take advantage of the same common digital-forensics tools used by experts to gather important volatile evidence, while doing little more than simply inserting a USB device into the computer."

Microsoft ships COFEE on a tiny USB device to law-enforcement agencies in almost 190 countries worldwide. The company has been working with Florida State University and University College Dublin to develop future versions of COFEE that can adapt to the evolving needs of digital forensics.

Security researchers point out that COFEE provides no useful tools for individuals, though of course it's possible that criminals might investigate how the code works to find ways around its capabilities.

The most important aspect of this story, of course, is that I avoided obvious headline puns such as "Microsoft COFEE Leaks Online," "Microsoft COFEE: HOT!" or "CSI: Redmond." You're welcome.

What does it look for? Kiddie ****?

"What does it look for? Kiddie ****?"

More than likely it's a search tool that can search for text in files that are present and/or searches for deleted files and traces of files that have been overwritten using data recovery techniques. Some data forensics tools can also scan images for specific faces or content too. I wonder how this would stack up against DoD-level data wipe tools.

I'd also imagine that there are brute-force password cracking tools in there, and/or a scan for insecure login accounts. It's always possible that it may take advantage of some kind of backdoor in Windows, or in the encryption standards that it uses (if one even exists - that's only speculation). If Microsoft developed this, then there's always a possibility that they developed some kind of mechanism where approved law officials would have easier access to user-encrypted data on Windows.

COFEE isn't a stand-alone tool itself. It's a set of scripts that run other tools (almost all of which are publicly available already) to gather forensic data. The goal of COFEE was to provide an easy-to-use way for untrained LEOs to gather forensic data without tainting it.

One other note: I don't think it's true that "COFEE isn't available legally to individuals". Microsoft hasn't released it, but there aren't any legal restrictions on possessing or using it, at least in the US.

Uh oh. Looks like Steve Gibson won't be needed on Security Now anymore then. ;)

Despite not knowing anything about this tool, I disagree with Microsoft's statement about it. Heck, just plugging a USB device in is going to create disk activity, RAM activity, etc...possibly enough to compromise anything found on the PC.

Looks like it's perfect for identifying the victims of this nasty little Windows-only virus.

Another reason NOT to buy a PC.

Ah, sweeps month. A story put together by someone who doesn't understand technology, doesn't site statistics, or bother to indicate where the person actually got the virus.

infinitetroll - did you write it yourself?

Where to start....

First - it never says "Windows only".

Second - it never says how the person got infected. While it may have been a self-reproducing virus (what virus actually means), more than likely it was a trojan horse that the user launched without paying attention - something that can infect Windows, Linux or Mac.

Third - It never mentions what version of the OS, or if any AV or anti-malware software was installed. It also fails to mention if any patches were actually applied or if there was a firewall - again something that impacts any system.

Fourth - The FUD factor of "This could happen to you!!!" is about on par with "They stole my organs!" They don't site any number of users this has happened to. The only numbers they do site is the number of infected computers connected to the internet (20M) and total computers connected (1B). Looking at the number 20 million is classic FUD. Quick math shows it's 2%.

There's more, but frankly I've already spent more time on this than I care to.

wtf can I get the Hot Coffee Mod, I've been drivin around for hours and I can't even find a paint booth!

"Heck, just plugging a USB device in is going to create disk activity, RAM activity, etc.."

I would imagine it would be a streamlined environment (knowing Microsoft, probably a customized, bootable WinPE USB stick) to get around that exact problem.

@sx4sport: +1

Does Microsoft have a DONUT app to go along with that? (or if you're in Canada, a TIMBIT app?)
