Running an I2P Svartkast on the Raspberry Pi: Even more cheap hardware to leave on someone else's network
This is sort of a sequel to a previous article I wrote titled "Running an I2P Svartkast on the Raspberry Pi: Even more cheap hardware to leave on someone else's network". In that article I answer the obvious question of what the hell a Svartkast is, as well as show how to make one out of a Raspberry Pi.

Economics of Information Security Paper Reviews and Notes
These are my write-ups and notes for the papers I've been reading in the "Economics of Information Security" class I'm enrolled in. I'm guessing most of my readers won't get much out of them unless they have read, or plan to read, the same papers.

Identifying the true IP/Network identity of I2P service hosts
This is my project proposal for the "Advanced Topics in Privacy" class I'm in. Please share with me your thoughts and ideas. Or at the very least, try out I2P and see how you can use it alongside Tor.

Counter WMF Exploit with the WMF Exploit
I used H D Moore's "Windows XP/2003/Vista Metafile Escape() SetAbortProc Code Execution" revision 1.12 Metasploit module to create a WMF file that automatically runs "regsvr32 -u shimgvw.dll" to counter the exploit. Clicking the link may run code on your computer or crash your browser if you are using IE so click with caution. More of a fun experiment than anything.
