An Adobe security researcher has released an open-source analyzer tool that can determine whether a Win32 binary file contains malware. Karthik Raman, who announced the tool Thursday in a blog post, said it uses "machine learning algorithms" to classify the file in question, either .exe or .dll, as clean, malicious or unknown. The offering is designed for use by "first responders" at organizations, such as IT administrators and anti-virus analysts, so they can develop faster signatures. The tool is available for download here.
