| 01:30 | | * McMartin checks the stats on his network-facing Intel chip |
| 01:30 | <&McMartin> | It appears to not have the dangerous feature in it. |
| 01:30 | <&McMartin> | It's also, apparently, classified by Intel as a Mobile Processor! |
| 01:37 | <&McMartin> | ... and my Windows machine might be so old that the feature didn't exist yet |
| 01:38 | | * Alek snickers. |
| 01:38 | <&ToxicFrog> | What counts as "network facing" here? Is "the ability to send it TCP packets on any port" sufficient? |
| 01:38 | <&McMartin> | It's the same generation, but it's from very early in that generation and the feature was introduced partway through. |
| 01:39 | <&ToxicFrog> | I can't seem to find technical details on the exploit >.< |
| 01:39 | <&McMartin> | This has not been reported in detail, no. |
| 01:39 | <&McMartin> | But in this case, "network facing" means "portscanning my IP will hit this computer at least once" |
| 01:40 | <&ToxicFrog> | based on amt-howto(7), AMT listens on tcp:16992 |
| 01:41 | <&ToxicFrog> | With a serial terminal on 16994 |
| 01:41 | <&McMartin> | Ports I happen to know are closed, anyway, but I'm curious about the local exploit possibility |
| 01:41 | | * ToxicFrog nods |
| 01:42 | <&McMartin> | It seems Xenon's Celeron N2830 isn't vulnerable, and Astatine's a Core i7 with a three-digit product code in the Nehelem era, but I don't recall the exact one offhand - I merely notice that some of the spec sheets don't even include AMT/vPro on their spec sheets because it didn't exist yet |
| 01:42 | <&ToxicFrog> | In my case I take the stance that if someone has local access to these machines I've already lost, because there's nothing stopping them from just walking away with them. |
| 01:42 | <&McMartin> | Yeah, the remaining two systems are laptops~ |
| 01:43 | <&ToxicFrog> | (including the server, which is a laptop with two external drive arrays; you can comfortably fit the whole thing in a backpack if you leave the UPS behind) |
| 01:43 | <&McMartin> | Osmium (and thus Thoth) are BIOS-based and can be checked there; I'm pretty sure the chips are Sandy Bridge Core i7s and probably have the tech present but disabled in BIOS. |
| 01:44 | <&McMartin> | And then there's the MBP, and god only knows what that has enabled |

| 04:13 | <@Alek> | Pentium E5400 here, how do I check? |
| 04:13 | <&McMartin> | Use these search terms: Ark intel Pentium E5400 |
| 04:14 | <&McMartin> | And look for whether it supports "Intel vPro" technology |
| 04:14 | <&McMartin> | If it doesn't then the exploitable system doesn't even exist |
| 04:14 | <&McMartin> | If it does then it exists but (if it's consumer-level) is probably disabled by default |

| 16:27 | <@gnolam> | Handling different aperture sizes in spectrophotometry. |
| 16:33 | <@ErikMesoy> | So not littoral aperture science. |
