  8. 8. Evolution of Cloudflare Bot Management Next Gen Bot Management Mitigation at Scale Cloudflare released solutions that stopped most malicious automated attacks. Cloudflare launches next gen bot management that leverages machine learning on a curated subset of traffic across our network of 20M+ Internet properties. 8 Stop Bots for Customers Cloudflare developed advanced tools that enable customers to tailor solutions at scale
  9. 9. Common Use Cases Attempts to log into and take-over a user’s account by automatically applying previously stolen account credentials Stealing information from websites with malicious intent Bots click on your ads and register in your marketing analytics. Credential Stuffing Content Scraping/Spam Marketing Ad- click Fraud Fraudulently purchases goods to deprive legitimate customers or resell for a higher price Inventory Hoarding Credit Card Stuffing Tries to validate stolen credit cards to then make fraudulent purchases 9
  10. 10. What have you tried to date? ● Rate Limiting ● WAF ● Multi-Factor Authentication ● Homegrown solutions ● Javascript-based bot detection
  11. 11. Problems with Javascript ● Slow application performance because each request is evaluated at the vendor’s origin ● False negatives — failures to mitigate malicious bots that turn off Javascript ● Poor user experience by interfering with or breaking web applications ● Violation of user privacy and government non-compliance if sensitive data stored by Javascript in the browser is compromised ● Deployment headaches while managing and securing third-party Javascript libraries 11

  14. 14. Why does Cloudflare scale matter? We ran the same machine learning model on the same features but using only 1% of the data set - potentially available to our competitors. Results: - 10% decrease in anomaly detection - 80% decrease in detecting SPAM + 400% increase in captchas shown
  15. 15. Cloudflare Bot Management Methods Machine Learning Cloudflare’s ML trains on a curated subset of 425 billion requests per day across 20M+ Internet properties, to create a reliable “bot score” for every request. Behavioral Analysis Behavioral analysis detects anomalies in site-specific traffic, scoring every request on how different it is from the baseline. Automatic Whitelist Because not all bots are bad, the solution automatically maintains and updates a white list of "good" bots, such as those belonging to search engines. Mobile Our mobile solution prevents attacks against mobile application APIs by impersonation and emulation bots and by hijacked mobile apps. 15 Detection Protection

  17. 17. Mitigation Options All mitigations of Bot management on your website undergo three stages to insure compatibility and effectiveness with your traffic 1. Simulate/Log This mitigation is the least intrusive one and thus allows you to mitigate offline on your own time. You will receive a header to all your requests with our bot score. This is particularly relevant for spammed forums, online forms, or online voting platforms. 2. Captcha* This mitigation is the best first step for rolling out to production as it allows us/you to measure the amount of false positives without impacting the user experience. 3. Block This mitigation is the most effective and should only be used in production after careful trade-off evaluation. * might require integration on your side

Alternative Actions and Punishment: Slow- down and waste bandwidth if (pathnameParts[1] == 'jpg') { var req = new Request('https://d3hv8qdd474bjn.cloudfront .net/nyancat_large.jpg?r=12'); // var req = request; options.cf.resize = {}; options.cf.cacheTtl = 600; options.cf.resize.width = 9999; options.cf.cacheKey = 'nyan'; options.cf.resize.quality = 1; // slowRequest = false; if (clientTrustScore <= 30) { await sleep(1000); var options = { "cf" : { "cacheTtl" : 30 } };
