This document discusses the dark side of web security, including automated threats from bots and attackers. It notes that traditional security like flossing is difficult to measure effectiveness. It outlines the OWASP top 10 vulnerabilities and automated threats attackers use. While captchas are meant to stop bots, services have made bypassing captchas easier. If a site has value like money, data, or content, there is value in exploiting it. Detection of attacks is difficult as attackers use many proxies and fingerprints to avoid detection. Patching is not enough, and spikes in traffic from many IPs could indicate an attack.

1. The Dark Side of Security

2. Not this dark side…

3. … the darkness that hides the unknown

4. Traditional web security is like flossing.
Deep down we know we should care,
but it's difficult to see if the effort is paying off.

5. OWASP Top 10
A1 – Injection
A2 – Broken Authentication and Session Management
A3 – Cross-Site Scripting (XSS)
A4 – Insecure Direct Object References
A5 – Security Misconfiguration
A6 – Sensitive Data Exposure
A7 – Missing Function Level Access Control
A8 – Cross-Site Request Forgery (CSRF)
A9 – Using Known Vulnerable Components
A10 – Unvalidated Redirects and Forwards

7. Our user-friendly APIs enable our attackers

8. Not just these APIs

9. The APIs we expose unintentionally.

10. The APIs we expose unintentionally.

11. The APIs we expose unintentionally.

15. It's more than just massive breaches
from large companies, too.

16. It's small continuous, streams of exploitable data

17. When you read about breaches, what do you do?

18. Even if you have the most secure site in the world,
we don't protect against legitimate user logins.

19. If your users were robots,
could you tell?

21. What percentage of traffic is from bots?

22. 92%
( Current record for automation against a login page, via Shape Security )
What percentage of traffic is from bots?

23. Why?

24. Do you… For example
Store a type of currency? actual money, point values, gift cards
Sell goods? physical, digital, services
Have unique PII? health care, social networks
Have user generated content? forums, social networks, blogs, comments
Have time sensitive features? tickets, flash sales, reservations
Pay for digitally validated behavior? ad clicks, reviews, "uber for X"

25. If you have value, there is value in exploiting you.

26. But we have captchas!

27. But captchas don't work.

28. Estimated 200 million+ hours spent
every year deciphering squiggly letters.

29. Services have been made making captcha bypass even easier.

30. Services have been made making captcha bypass even easier.

31. Ever wonder where these ads go?

32. There's big money in "Work from Home Data Entry" jobs

33. So we seek alternatives.

34. Some rely on simple behavior analysis

35. Some rely on kittens

36. Some rely on a love for death metal

37. Some are very high profile

38. How?

39. They use a lot of the same tools we already use.

46. Once you detect an attacker, they are easy to block.
Right?

47. One attacker from one machine
can be blocked by IP.

48. Many attackers sound dangerous but
aren't as common as they are made out to be.

49. One attacker using proxies to
look like thousands of users across the globe
is difficult to detect and block.

50. Spikes of traffic across many IPs are normal, except when they aren't

51. The devices themselves leave fingerprints

52. And tools are made to leave no fingerprints

53. Lots of tools.

55. We can't patch our way through this.

56. How would you react if you went from …
Legitimate traffic

57. To this
Automation detected and blocked
Legitimate traffic

58. Automation detected and blocked
Legitimate traffic
To this

59. Automation detected and blocked
Legitimate traffic
