Scripting #SWAG
RISE OF
THE
HYPEBOTS
Duct
Couldn’t buy anything due to bots
Decided to enter the game in 2012
Unfortunately still in the game.
Looks good tho?
About Me
Why Bots?
We Built the Internet
For Them.
The Bots We Loved
1988
1994
1999
2007
First Internet Bot spotted on IRC
AOL Releases WebCrawler
IRC’s first Malicious Botnet
First “large scale” HTTP botnet
Our (best) Internet
[SEO] Google is not the only bot anymore.
[HTML]“Readable” and Clean HTML is easy to
parse
[APIs] Speedy and Reliable
[Capitalism] Purchasing should be easy.
Test Driven Development
1. If you’re writing tests, you’re one evil
genius moment away from becoming a bot
reseller
2. If your site is using unit tests, you’re
making sure that your site will be easy to
bot.
CAPITALISM
ENCOURAGES
BAD BEHAVIOR
Why We Bot
Restricted supply increases demand for a heavily
marketed product
Speed run checkout system creates a problem that
requires an optimal solution
Optimal Solution: Computers using computers.
Why “They” Bot
Restricted supply increases demand for a heavily
marketed product
Buyers market allows for space for a “grey market”
to emerge to resell product.
Need a vast amount of restricted product for more
profit
Optimal Solution: Many computers using computers
How Bots?
Complex Systems
Simple Answers
Types of Bots
Browser Based Bot
‣ Mimics a user by loading a
browser
‣ Easier to script, and
harder to detect
‣ More expensive to scale
Low Level Bot
‣ Uses API calls to post
directly.
‣ Takes more initial
upfront investment
‣ Scale to thousands
easily.

BOT BOTS

Future Bot
And why we need to get
L0L totally rand0m
We Care about (your) money.
Resellers are not good consumers, often make more profit
than the company does.
Resellers crowding drops means that real consumers stop
purchasing.
Human’s perceive “fairness” and if a company isn’t fair, then
why give them money?
Blacklisting?
Bot Traffic Mimicks human traffic, so you’ll end up
blacklisting consumers
Accounts are purchased and dumped regularly
Since bots are deployed in clusters and behind proxies, IPs
will change each purchase (or each request)
Blacklisting means creating a useless database.
MAKE IT WORSE
MAKE IT WORSE
MAKE IT WORSE
MAKE IT WORSE
MAKE IT WORSEFalse Listings confuse bots and
consumers
In person sales just mean in person
resellers
Lottery based means bots buy lotto
tickets instead
Making the Web
Unpredictable Again
‣ Adding entropy into your system does not mean introducing
unreliability
‣ Measured unpredictability can make many tasks more
difficult
‣ Let’s encrypt our process, not just our passwords.
THIS AIN’T
A SCENE
IT’S AN
ARMS RACE
