The Dark Side of Security
- 1. The Dark Side of Security Jarrod Overson - @jsoverson - Shape 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
- 6. OWASP Automated Threats OAT-020 Account Aggregation OAT-006 Expediting OAT-019 Account Creation OAT-004 Fingerprinting OAT-003 Ad Fraud OAT-018 Footprinting OAT-009 CAPTCHA Bypass OAT-005 Scalping OAT-010 Card Cracking OAT-011 Scraping OAT-001 Carding OAT-016 Skewing OAT-012 Cashing Out OAT-013 Sniping OAT-007 Credential Cracking OAT-017 Spamming OAT-008 Credential Stuffing OAT-002 Token Cracking OAT-015 Denial of Service OAT-014 Vulnerability Scanning
- 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. Luis Von Ahn, creator of captcha * *
- 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 To this
- 60. To get an idea, search for : • <your company, service, or CMS> fullz • <your company, service, or CMS> sentrymba • <your company, service, or CMS> carding • <your company, service, or CMS> <tool> tutorial Not sure if you have a problem?
