For a long time I've been fascinated with online polls, contests and forms in which one can vote to win something (for either you or your friends). The fun ones, I think are the ones where no captcha or e-mail addresses required, or those in which you can vote multiple times. I used one of these many years ago to vote for the "cutest baby". No we didn't win, because someone beat me to my own game.
Enter http://www.johnstrandvsjohnstrand.com! Now this is a vote I can rock...
So to start, I fired up burp, set the browser proxy and went to the site and voted for my favorite "model". Once I had that captured, I looked to see what I could see.
Now there were no post request for the site, but I did note one for "pollmill.com". A little inspection found that yes, this was the actual vote cast for my favorite "model".
My first instinct was to right click on the request, and "send to repeater". Once there, I used repeater to re-submit my vote; sure enough I was returned a page and it had accepted my vote AGAIN using all os the same tokens. No uniqueness tracking here! This is good.
I clicked on the repeater submit again. And again. And again. Woohoo, 5 votes! This is going to take a long time. Click faster! Then I noticed that some of my responses included the phrase "You are voting too quickly...". Nuts, this is no good, how will I rock the vote?
I started exploring other options. Ooh, how about the "Generate script" option from the original post request?
This looks promising! It needs to have the extender installed, and only works in the Pro version. Hmm, python, ruby, perl and PHP? Yes please! However with all of these options (except for PHP) I could not get them to work for me. I didn't spend a lot of time troubleshooting either.
I posed the question of scripting a POST request to my co-workers. John Sawyer came back with leveraging the "copy to curl command".
Oooh, this could be promising! So, I copied the original post request to the clipboard and wrote a little shell script with a loop, and pasted the request in the loop.
I quickly noted that I was getting responses back that I was voting too quickly. So I implemented a sleep function in the loop. With a little trail and error, found that about one request a minute was good. This is the script I ended up with.
#!/bin/bash COUNTER=0 while [ $COUNTER -lt 1000 ]; do sleep 60 curl -i -s -k -X 'POST' \ -H 'Origin: http://pollmill.com' -H 'X-CSRF-Token: oE8RUleEzT3UCiLD5L0Q0TrrYOZzVG0gMD+Bka0wcZs=' -H 'X-Requested-With: XMLHttpRequest'\ -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36' \ -H 'Content-Type: application/x-www-form-urlencoded' -H 'Referer: http://pollmill.com/f/who-is-the-sexiest-hacker-on-the-planet-ghqn2aw/answers/new.fullpage' \ -b 'respondents_uuid=7177cb1de8dc5844a7e2bb826f99257f; _session_id=ff6e43123a4e62c89faf24438b85c178; __utma=201964816.1687400874.1397497341.1398352538.1399483676.10; \ __utmb=2019648184.108.40.2069483676; __utmc=201964816; __utmz=201964816.1399483676.10.7.utmcsr=johnstrandvsjohnstrand.com|utmccn=(referral)|utmcmd=referral|utmcct=/' \ --data-binary $'utf8=%E2%9C%93&authenticity_token=oE8RUleEzT3UCiLD5L0Q0TrrYOZzVG0gMD%2BBka0wcZs%3D&_format=fullpage&update_entries%5B%5D=207231&answer%5B207231%5D%5Bvalue%5D%5B%5D=1309284&commit=Submit' \ 'http://pollmill.com/f/who-is-the-sexiest-hacker-on-the-planet-ghqn2aw/answers.js' let COUNTER=COUNTER+1 done
It has been formatted to fit your screen try removing "\"'s if it doesn't work...
I let this script run for about 10 hours, pointed the mic skyward and dropped it. Vote rocked.
Now, I know this isn't anything super technical about burp but sometimes the simple elegant solutions wins. It was something I didn't know about and turned out to be lots of fun. I could even imagine how I might be able to use similar request and other loops with a shell script for fun too. Or, there is always burp sequencer...
But that is a story for another day.

- Don't let hackers know Mandiant founder checks his email on an iPad. Oh.
- Deactivated User Accounts Die Hard
- Dropbox finally fixes security vulnerability
- "SHA-2 Takes Off
- Why Threat Intelligence Is Like Teenage Sex
- "Your Android phone viewed illegal porn. To unlock it - Scams such as this one are popular as money-making schemes. Everything from this to sextortion.
- Google acquires restaurant website builder Appetas - Please tell me they can make them not use Flash. It should be banned form all resturant sites. I won't eat there if they use Flash, yea right, then I would have no place to eat.
- "Serious security flaw in OAuth - OAuth is used by many large sites, including the OpenID service. Authentication is great, it should be shared and open and everyone should use the same protocol, except when that protocol has a flaw, then we are screwed.
- McAfee accused of McSlurping Open Source Vulnerability Database - OSVD is a great resource, and if you are using it for commercial purposes, give them some money. Except if you are McAfee, then apparently you can just spider the entire site instead. Tisk tisk.
- Unix ‘find’ Cheat Sheet - I love cheat sheets. Post-exploitation goodness here.
- 300k servers vulnerable to Heartbleed one month later - Fact is there are a billion sites on the Internet, so 300k is still a small percentage, but it depends on how you count. How many are using SSL? In any case, anytime there is a widespread vulnerability, people won't patch. The more widespread, the more sites that will remain vulnerable. What are we doing wrong that people aren't paying attention to security? Or maybe they are and are just accepting the risk.
- New iPhone lock screen flaw gives hackers full access to contact list data - I mean really, who cares? If you lose your phone, or it is stolen, little can be done to protect your information. I think remote wipe is your best bet in terms of personal security. Phones are lost or stolen all the time, though I am guessing here, but usually the theif cares little about your email or pictures. Still, its Apple's responsibility to provide a more secure platform as this is not the first time this problem has come up, and likely not the last. Thought they do make available the fingerprint reader, but as a user, this is more annoying than anything else. In fact, many don't use it because its annoying. Dear Apple, I want a bigger phone, so in the mean time I have a Note III until you can make a phablet.
I'm looking forward to seeing folks at BSides in Boston, San Antonio, and Nashville.
