I wanted to put together a few thoughts I had on gifts for my fellow hackers this holiday season. I’m including a variety of different things to appeal to almost anyone involved in information security or hardware hacking, but I’m obviously a bit biased to my own areas of interest. I’ve tried to roughly categorize things, but they tend to transcend boundaries somewhat. Got a suggestion I missed? Hit me up on Twitter.
I wanted to use duplicity to backup to Google Cloud Storage. I looked into it briefly and found that the boto library, originally for AWS, also supports GCS, but only using authorization tokens. I’d rather use a service account, for which authorization tokens are not available.
I looked into the options and the best information I could find was a Medium post, but it also describes using authorization tokens and creating a separate GMail/Google Apps account for the access. I’d really prefer to go with a service account to avoid having to sign up another account, and to be able to use more granular ACLs for the service account.
It turns out there’s a boto plugin for GCS with OAuth2
support, but
enabling a boto plugin in duplicity isn’t straight-forward. You can point it to
a “plugin directory” that causes duplicity to import any python files in the
directory, but this doesn’t work if you point it directly to the
gcs_oauth2_boto_plugin directory.
Install the following:
Create a GCS bucket. In my case, I set the default storage class to “nearline” because I expect backups to be infrequently accessed (I hope), and I plan to retain the data for the minimum 30 day retention. It’s also cheaper than standard storage, so a great combination for backups.
Next up, you need to create a service account and grant it the appropriate permissions on the bucket. Go through IAM > Service Account and create a new service account. You don’t need to grant it any roles at this time, but at the end, you should select to “Create key” and download a JSON-formatted service account key.
Go back to the bucket you created, and go to the Permissions tab. Add the service account you just created as a “Storage Object Creator” and a “Storage Object Viewer”.
For this, you’ll need the Google Cloud SDK tool
gsutil. Run gsutil -e -o <path to your new config>, and provide the JSON
file when prompted. Note that the JSON file is only referenced by the config,
so if you move it somewhere else, you’ll need to update the configuration. (Or
move it first, then run it.)
This will create the necessary configuration for boto to authenticate to GCS.
You’ll still need to add the support for OAuth2 authentication, so first create
an empty directory to serve as your plugin directory. In my case, I created a
directory ~/.config/boto/plugins for all my plugins. In it, I created one
file called gcs.py whose only contents is the following:
1
import gcs_oauth2_boto_plugin
I then added the following to the bottom of my boto configuration file:
1
2
[Plugin]
plugin_directory = /home/matir/.config/boto/plugins
This will result in boto loading the gcs_oauth2_boto_plugin python module for
OAuth2 authentication on GCS when being loaded into duplicity.
At this point, it’s almost like running any duplicity backup. If you chose to
place your boto configuration in a non-standard location, just set the
environment variable BOTO_CONFIG to point to the configuration file. I run
the following:
1
2
3
4
5
6
7
export BOTO_CONFIG=${HOME}/.config/boto/boto_backups
duplicity \
incremental \
--full-if-older-than 30D \
${HOME} \
gs://demo-backup-bucket
One last post from Summer Camp this year (it’s been a busy month!) – this one about the “Data Duplication Village” at DEF CON. In addition to talks, the Data Duplication Village offers an opportunity to get your hands on the highest quality hacker bits – that is, copies of somewhere between 15 and 18TB of data spread across 3 6TB hard drives.
I’d been curious about the DDV for a couple of years, but never participated before. I decided to change that when I saw 6TB Ironwolf NAS drives on sale a few weeks before DEF CON. I wasn’t quite sure what to expect, as the description provided by the DDV is a little bit sparse:
6TB drive 1-3: All past convention videos that DT can find - essentially a clone of infocon.org - building on last year’s collection and re-squished with brand new codecs for your size constraining pleasures.
6TB drive 2-3: freerainbowtables hash tables (lanman, mysqlsha1, NTLM) and word lists (1-2)
6TB drive 3-3: freerainbowtables GSM A5/1, md5 hash tables, and software (2-2)
Drive 1-3 seems pretty straightforward, but I spent a lot of time debating if the other two were worth getting. (And, to be honest, I think they’re cool to have, but not sure if I’ll really make good use of them.)
I want to thank the operators of the DDV for their efforts, and also my wife for dropping off and picking up my drives while I was otherwise occupied (work obligations).
It’s worth noting that, as far as I can tell, all of the contents of the drives here is available as a torrent, so you can always get the data that way. On the other hand, torrenting 15.07 TiB (16189363384 KiB to be precise) might not be your cup of tea, especially if you have a mere 75 Mbps internet connection like mine.
If you want a detailed list of the contents of each drive (along with sha256sums), I’ve posted them to Github. If you choose to participate next year, note that your drives must be 7200 RPM SATA drives (apparently several people had to be turned away due to 5400 RPM drives, which slow down the entire cloning process).
Drive 1 really does seem to be a copy of infocon.org, it’s got dozens of conferences archived on it, adding up to a total of 132,253 files. Just to give you a taste, here’s a high-level index:

Drive 2 contains the promised rainbow tables (lanman, ntlm, and mysqlsha1) as well as a bunch of wordlists. I actually wonder how a 128GB wordlist would compare to applying rules to something like rockyou – bigger is not always better, and often, you want high yield unless you’re trying to crack something obscure.

Drive 3 contains more rainbow tables, this time for A5-1 (GSM encryption), and extensive tables for MD5. It appears to contain the same software and wordlists as Drive 2.

Apache Tapestry uses HMACs to verify the integrity of objects stored on the client side. This was added to address the Java deserialization vulnerability disclosed in CVE-2014-1972. In the fix for the previous vulnerability, the HMACs were compared by string comparison, which is known to be vulnerable to timing attacks.
No new release of Tapestry has occurred since the issue was reported. Affected organizations may want to consider locally applying commit d3928ad44714b949d247af2652c84dae3c27e1b1.
This vulnerability was discovered by David Tomaschik of the Google Security Team.
Okay, I’m back from Summer Camp and have caught up (slightly) on life. I had the privilege of giving a talk at BSidesLV entitled “CTFs for Fun and Profit: Playing Games to Build Your Skills.” I wanted to post a quick link to my slides and talk about the IoT CTF I had the chance to play.
I played in the IoT Village CTF at DEF CON, which was interesting because it uses real-world devices with real-world vulnerabilities instead of the typical made-up challenges in a CTF. On the other hand, I’m a little disappointed that it seems pretty similar (maybe even the same) year-to-year, not providing much variety or new learning experiences if you’ve played before.
