Computer Online Forensic Evidence Extractor

Computer Online Forensic Evidence Extractor

Computer Online Forensic Evidence Extractor (COFEE) is a tool kit, developed by Microsoft, to help computer forensic investigators extract evidence from a Windows computer. Installed on a USB flash drive or other external disk drive, it acts as an automated forensic tool during a live analysis. Microsoft provides COFEE devices and online technical support free to law enforcement agencies.

Development and distribution

COFEE was developed by Anthony Fung, a former Hong Kong police officer who now works as a senior investigator on Microsoft's Internet Safety Enforcement Team.[1] Fung conceived the device following discussions he had at a 2006 law enforcement technology conference sponsored by Microsoft.[2] The device is used by more than 2,000 officers in at least 15 countries.[3]

A case cited by Microsoft in April 2008 credits COFEE as being crucial in a New Zealand investigation into the trafficking of child pornography, producing evidence that led to an arrest.[1]

In April 2009 Microsoft and INTERPOL signed an agreement under which INTERPOL would serve as principal international distributor of COFEE. University College Dublin's Center for Cyber Crime Investigations in conjunction with INTERPOL develops programs for training forensic experts in using COFEE.[4] The National White Collar Crime Center has been licensed by Microsoft to be the sole US domestic distributor of COFEE.[5]

Public leak

On November 6, 2009, copies of Microsoft COFEE were leaked onto various BitTorrent websites.[6] Analysis of the leaked tool indicates that it is largely a wrapper around other utilities previously available to investigators.[7] Microsoft confirmed the leak, however a spokesperson for the firm said "We do not anticipate the possible availability of COFEE for cybercriminals to download and find ways to ‘build around' to be a significant concern". [8]

Use

The device is activated by being plugged into a USB port. It contains 150 tools and a graphical user interface to help investigators collect data.[1] The software is reported to be made up of three sections. First COFEE is configured in advance with an investigator selecting the data they wish to export, this is then saved to a USB device for plugging into the target computer. A further interface generates reports from the collected data.[7] Estimates cited by Microsoft state jobs that previously took 3–4 hours can be done with COFEE in as little as 20 minutes.[1][9]

COFEE includes tools for password decryption, Internet history recovery and other data extraction.[2] It also recovers data stored in volatile memory which could be lost if the computer were shut down.[10]

Detect and Eliminate Computer Assisted Forensics (DECAF)

Detect and Eliminate Computer Assisted Forensics (DECAF) is a counter intelligence tool specifically created around obstructing COFEE. DECAF provides real-time monitoring of COFEE signatures on USB devices and in running applications. When a COFEE signature is detected, DECAF performs numerous user-defined processes. These may include COFEE log clearing, ejecting USB devices, and contamination or spoofing of MAC addresses.
