And how do you establish the connection to deploy your remote privilege escalation exploit against the Intel Management Engine?
- belter 3y agoHey I am not ChatGPT :-) But the answer has three parts: 1- "...The Intel Management Engine always runs as long as the motherboard is receiving power, even when the computer is turned off..." 2- The Intel Management Engine is the remote privilege escalation.(Read on the known and unpublished vulnerabilities). 3- Over-the-Air Firmware Updates... If I say more we both will end on a secure facility.
- FirmwareBurner 3y ago>3- Over-the-Air Firmware Updates... Mate I feel like you're getting your security know-how from watching Mission Impossible. "Over-the-Air" doesn't actually mean you can magically beam SW updates wirelessly through the air to the Intel chip like in the hacker/spy movies, as airgapped networks, as per name, don't have wireless cards. Intel ME still requires a network connection to the internet/network from which you want to apply the update. If you're on an airgapped network this becomes impossible to do without first breaching the airgapped network physicality, but this is not what happened according to the article, they just compromised some employee Microsoft/O365 account which is on the less secure network anyway and probably stole whatever IP they could find shared through the e-mail accounts and on Sharepoint.

- FirmwareBurner 3y agoDon't know what you saw in there but all that material disproves your claims.
- soganess 3y agoWait, I swear I'm not being intentionally daft, but in this scenario my air-gapped system has a (intel) wireless card? And we are certain the ME can manage this wireless card? And is actively listening for a wireless update while 'off'? From an unauthenticated connection?
- FirmwareBurner 3y ago>in this scenario my air-gapped system has a (intel) wireless card? If you have a wireless card then your system was never airgapped to begin with. Parent makes some wild confusions.
- belter 3y agoSee page 5 on how the CPU has now just become another peripheral. Notice the Out-of-Band Wireless into the Motherboard - https://recon.cx/2014/slides/Recon%202014%20Skochinsky.pdf https://recon.cx/2014/slides/Recon%202014%20Skochinsky.pdf Is dismounting your Motherboard what you mean by not having a card?
- FirmwareBurner 3y ago>Notice the Out-of-Band Wireless That's just the wireless controller on the chip but its not enough to have wireless communication actually work. You still need a wireless PHY which modulates the digital signal into radio waves, and an antennae attached to actually have wifi. On it's on it does nothing, it's just a piece of silicon that can't achieve radio communication.

"AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers" - https://arxiv.org/abs/2012.06884 https://arxiv.org/abs/2012.06884 "In this paper, we show that attackers can exfiltrate data from air-gapped computers via Wi-Fi signals. Malware in a compromised air-gapped computer can generate signals in the Wi-Fi frequency bands. The signals are generated through the memory buses - no special hardware is required."
