bsqlbf is a tool for Blind SQL Injection attacks, a pretty nifty one too!
The author says there are similar tools about, but he’s tried to combine all the techniques into one compact but complete tool.
# -get now support resume (with -start option)
# -get to fetch files (thank you ilo AGAIN)

# + -rtime option added (IDS bypass)
# + -rproxy option added (IDS bypass)

There is a decent GUI front end in Perl-Tk made by Gandalfj, a Windows version is available for download too.
