Reminder: WLUG Meeting Tomorrow Jan 18th, 2018 Topic: Spectre and Meltdown!
by Tim Keller Jan. 18, 2018

Jan. 18, 2018

We've got a meeting this week! Short Topic: Spectre and Meltdown. What it is, what it does, etc. I figure this is pretty topical as many of us are starting to wrap our heads around the performance implications as well as the tackling the task of patching many systems. Location: Campus Center, Mid Century Rm 331 Time: 7pm Snacks and Refreshments will be provided.

Hi everybody, I've noticed that the Ubuntu 16.04 ISO is bootable on systems with BIOS as well as UEFI. From scratch, I've remastered Ubuntu, but my ISO file is only bootable via BIOS. I'd like to remedy that situation by figuring out what magic is needed so that my ISO file can be booted either way. I have a chroot directory in which my files live. I have scripts that convert all of that into an ISO file. My guess is that I need a new/modified incantation of mkisofs plus some additional files for UEFI.

If things like that > exist, why care about encryption vulnerability? Because with properly configured wireless and patched clients, you can be sure you are connecting to the trusted network, not a Man-in-the-Middle. It requires mutual authentication, which happens for example on the WPI wireless network by using EAP-TLS certificates. The client is supposed to verify the server's certificate and the server of course verifies the client's certificate. Unfortunately, most networks don't use EAP but rather use Pre-Shared Keys (WPA2-PSK). > If you need to patch both sides to be secure, > then you are not secure in the coffee shop no > matter what you do.

In the strictest sense this is true, but as far as the KRACK attack goes, the wireless AP side is much less likely to be a problem, because the vulnerabilities are in parts of the standards that are not often used (802.11r "Fast Roaming" for example). The client-side vulnerabilities, especially in Linux/Android, are much more serious. On Linux, the client can be tricked into using a null session key. However, in a coffee shop KRACK is moot because most coffee shops don't use encryption at all to begin with. In any case, WPI's recommendation to use the VPN if you are not sure of your device's or the network's immunity to KRACK is sound, because even if there was a M-i-t-M, they still would not be able to decrypt the VPN traffic. Security is helpful in layers. Belt-and-suspenders.

You've got to avoid computers to be fully secure. But let's not get that paranoid. I pulled Cat 5 cable through the house years ago and never use wireless, but WPI has its hair on fire, and sent Professor Diane email (through Microsoft cloud service) to install "upgrades" immediately. I told her to at least wait until she has her computer back in the office and plugged into WPI cable. I have a friend who has been without a computer for a month or two because he tried to upgrade firmware and could not re-boot. This is very embarrassing for the authors of the standard, but is it really a big problem? Several meetings ago, somebody brought a device to the WLUG meeting that, as I understood it, pretends to be a wireless router and interposes itself into any nearby connection. If things like that exist, why care about encryption vulnerability? If you need to patch both sides to be secure, then you are not secure in the coffee shop no matter what you do. In any case, if you are using the wireless to connect to a web site or "cloud" server, then the wireless connection is the least of your insecurities. -- Keith

Nothing so simple, unfortunately. This class of vulnerability is actually a collection of 10 CVEs, which encompass both the AP side and client side. If you've patched the AP side, for example, the attacker may still be able to compromise the set of session keys on the client side, and decrypt all of the client sent traffic. You've got to patch both sides to be fully secure. """ The direction in which packets can be decrypted (and possibly forged) depends on the handshake being attacked. Simplified, when attacking the 4-way handshake, we can decrypt (and forge) packets sent by the client. When attacking the Fast BSS Transition (FT) handshake, we can decrypt (and forge) packets sent towards the client. Finally, most of our attacks also allow the replay of unicast, broadcast, and multicast frames. For further details, see Section 6 of our research paper<https://www.krackattacks.com/#paper>.

""" What if there are no security updates for my router? Our main attack is against the 4-way handshake, and does not exploit access points, but instead targets clients. So it might be that your router does not require security updates. We strongly advise you to contact your vendor for more details. In general though, you can try to mitigate attacks against routers and access points by disabling client functionality (which is for example used in repeater modes) and disabling 802.11r (fast roaming). For ordinary home users, your priority should be updating clients such as laptops and smartphones.
