This was an ISACA presentation by Nsale Ronnie a top hacker in Africa working with Ernst and Young. He demonstrated how other governments are leading by far in the nature of their espionage through hardware.

Cyber criminal advantageDefault usernames and passwordsUnsecured Debugging portsUnencrypted Trojans and Back doors 22. Introduction to Plasnito 23. DEMO 24. RealityThis is not a vulnerability :It is sheer bad design due to legacy.Don't expect a patch.Fixing those issues will probably require breaking backward compatibility with most standards (PCI, PCIe, TPM). 25. Why crypto won't save youWe can fake the bootking/password prompt by booting a remote OS (Truecrypt/Bitlocker)Once we know the password, the BIOS backdoor can emulate keyboard typing in 16bit real mode by programming the keyboard/motherboard PIC microcontrollersIf necessary, patch back original BIOS/firmwaresremotely. 26. Why crypto won't save youTPM + full disk encryption won't save you either :It's a passive chip : if the backdoor doesn't want explicit access to data on the HD, it can simply ignore TPM.Your HD is never encrypted when delivered to you. You seal the TPM when you encrypt your HD only. So TPM doesn't prevent backdooringfrom anyone in the supply chain. 27. How about Antivirus?????Putting an AV on a server to protect against unknown threats is purely cosmetic.You may as well put lipstick on your servers... 28. Example: 3 year old bootkit 29. Example: 3 year old bootkit 30. RemediationFlash any firmware upon reception of new hardware with open source software you can verifyPerform checksums of all firmwaresby physically extracting them (FPGA..) : costly !Verify the integrity of all firmwaresfrom time to timeUpdate forensics best practices :1) Include firmwaresin SoW2) Throw away your computer in case of intrusionEven then... not entirely satisfying : the backdoor can flash the original firmwaresback remotely. 31.
