Librem13v2 TPM upgrade

I have upgraded my TPM firmware on my Librem13v2. Its keys are now safe. \o/

Back in 2017 we had the Infineon disaster (aka ROCA). I’ve written about it before about how bad it is and how to check if you’re affected with a simple tool.

I TAKE NO RESPONSIBILITY IF YOU BRICK YOUR DEVICE OR FOR ANYTHING ELSE BAD HAPPENING FROM YOU FOLLOWING MY NOTES.

Before the upgrade

$ tpm_version | grep Chip
Chip Version:        1.2.4.40    <--- Example vulnerable version
$ cbmem -c | grep Purism         # I upgraded coreboot/SeaBIOS just before doing this.
coreboot-4.9-10-g123a4c6101-4.9-Purism-2 Wed Nov 13 19:54:43 UTC 2019 […]

The Future of Hidden Features

You may have noticed last week that Ubiquiti added a new “feature” to their devices in a firmware updated. According to this YouTube video from @TomLawrenceTech, Ubiquiti built an new service that contacts a URL to “phone home” and check in with their servers. It got some heavy discussion going, especially on Reddit.

The consensus is that Ubiquiti screwed up here by not informing people they were adding the feature up front and also not allowing users to opt-out initially. The support people at Ubiquiti even posted a quick workaround of blocking the URL at a perimeter firewall to prevent the communications until they could patch in the option to opt-out. If this was an isolated incident I could see some manner of outcry about it, but the fact of the matter is that companies are adding these hidden features more and more every day.

The first issue comes from the fact that most release notes for apps any more are nothing aside from platitudes. “Hey, we fixed some bugs and stuff so turn on automatic updates so you get the best version of our stuff!” is somewhat common now when it comes to a list of Continue reading

SEC 2. Data plane and control plane protection in the networking (Nokia, Cisco and Mellanox/Cumulus) for IPv6.

Hello my friend,

After the release of the previous article outlining the data and control plane security for IPv4 in Cisco, Nokia and Mellanox/Cumulus (link) I’ve got several requests about the security in IPv6. The requests were fair enough and with this article we close this gap.
