This paper describes three projects that are part of a research agenda in support of digital forensic inves- tigations. The R&D activities involve developing new technologies and forensic tools to address real-world problems related to electronic/digital crime. The three projects are the DNA project, dedicated to cryptanaly- sis of passwords; the UnMask project, which ad- dresses the issue of automated support for investiga- tion of phishing attacks; and the PAPA project, which was designed to capture interactions with cyberstalk- ers and perform sting operations. The DNA and Un- Mask tools are operational and undergoing testing. The testing of the PAPA tool suggested several alter- nate uses of the system.
