News of the Flame attack has spread faster than wildfire. While the attack effected only a small number of Endpoints, Flame signifies a new level of cyber threat that all IT security professionals need to understand in-depth.

View these presentation slides by IT Security expert, Randy Franklin Smith, as he walks you through the fascinating nuts and bolts of Flame and explains the technical details about how it worked and what lessons can be learned.

• Learn the technical details about how Flame worked
• How Flame was more than just sophisticated encryption exploits
• Take away lessons on how to defend against APTs

Take an in-depth look into the entire attack which featured more than just encryption exploits. Randy explores social engineering, removable devices and more.

    • Preview of Key Points How it worked Lessons learned© 2012 Monterey Technology Group Inc.
    • How Flame Worked 24 Command & Control Servers 84 Domain Names traffic-spot.bz trafffic-spot.com quick-net.info smart-access.net chchengingine.com chchengine.net flasp.webhop.net Internal Network© 2012 Monterey Technology Group Inc.
    • How Flame Worked Internal Network© 2012 Monterey Technology Group Inc.
    • How Flame Worked Flame’s 20MB of Capabilities • Bluetooth • Audio • USB • Backdoor accounts • Proxy server • Windows Update • Extendable modular architecture • File system search • Text summaries of interesting files • Logging • Trickle uploader • Anti-Malware aware Internal Network • Compression • SSL fallback to SSH© 2012 Monterey Technology Group Inc.
    • How Flame Worked Internal Network© 2012 Monterey Technology Group Inc.
    • How Flame Spread via WU 1. Flame activates on first computer (X) 2. Another computer (Y) wants to check for Windows Updates 3. Y defaults to automatic proxy server and broadcasts an NBNS request for WPAD (Web Proxy Auto-Discovery) 4. X answers back and spoofs itself as a proxy server 5. Y attempts to connect through X to Microsoft’s Windows update site and retrieve updates 6. X pretends to be Windows Update and sends back a bogus patch which contains Flame 7. But why does Y’s Windows Update validation logic trust the bogus patch?© 2012 Monterey Technology Group Inc.
    • How Flame Spread via WU 8. Flame signs the patch with a certificate that appears to be from Microsoft 9. The certificate was created from a Terminal Services Licensing Service CAL certificate 10. Then used to sign the patch 11. Why was it possible to do this?© 2012 Monterey Technology Group Inc.
    • The Incredible Part All possible because the bad guys pulled off a highly advanced cryptography trick Chosen prefix attack on the MD5 hash of certificate signature Real Fake TS Licensing Windows Update Certificate Certificate Signature from MS Certificate Authority© 2012 Monterey Technology Group Inc.
    • What Microsoft Did Wrong TS Licensing certs included code signing in the intended uses TS Licensing certs were ultimately signed by Microsoft’s Root CA Windows Update was looking for cert’s signed by Microsoft TS Licensing certs used MD5 This allowed the attackers to create a bogus certificate and forge signatures on bogus patches© 2012 Monterey Technology Group Inc.
    • Lessons learned MD5 was broken a long, long time ago Stop using technologies theoretically broken (intersection w/o stoplight syndrome) PKI is tricky Who do you trust and for what purposes? Good security still rules© 2012 Monterey Technology Group Inc.
    • Lessons learned  Good security still rules  Website categorization  Egress traffic analysis  Anti-malware  Whitelisting  Reduce attack surface • Turn off unneeded features like WPAD • Turn off bluetooth  Device control  Internally controlled patch management  Security log monitoring • New account reconciliation • New authentication packages© 2012 Monterey Technology Group Inc.
    • Bottom Line Endpoint security technologies really work Whitelisting Antimalware Device control Removable media Configuration management Internally controlled patch management© 2012 Monterey Technology Group Inc.
