Run Zephyr on QEMU Updated 2025-04-24 +Created 1970-01-01
View more
Real hardware is for newbs. Real hardware is for newbs.
Tested on Ubuntu 23.10 we approximately follow instructions from: docs.zephyrproject.org/3.4.0/develop/getting_started/index.html stopping before the "Flash the sample" section, as we don't flash QEMU. We just run it.
sudo apt install --no-install-recommends git cmake ninja-build gperf \
  ccache dfu-util device-tree-compiler wget \
  python3-dev python3-pip python3-setuptools python3-tk python3-wheel xz-utils file \
  make gcc gcc-multilib g++-multilib libsdl2-dev libmagic1
python3 -m venv ~/zephyrproject/.venv
source ~/zephyrproject/.venv/bin/activate
pip install west
west init ~/zephyrproject
cd ~/zephyrproject
west update
west zephyr-export
cd ~
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.16.1/zephyr-sdk-0.16.1_linux-x86_64.tar.xz
tar xvf zephyr-sdk-0.16.1_linux-x86_64.tar.xz
cd zephyr-sdk-0.16.1
./setup.sh
The installation procedure install all compiler toolchains for us, so we can then basically compile for any target. It also fetches the latest Git source code of Zephyr under:
~/zephyrproject/zephyr
The "most default" blinky hello world example which blinks an LED is a bit useless for us because QEMU doesn't have LEDs, so instead we are going to use one of the UART examples which will print characters we can see on QEMU stdout.
Let's start with the hello world example on an x86 target:
cd ~/zephyrproject/zephyr
west build -b qemu_x86 samples/hello_world -t run
and it outputs:
Hello World! qemu_x86
The qemu_x64 on the output comes from the CONFIG_BOARD macro github.com/zephyrproject-rtos/zephyr/blob/c15ff103001899ba0321b2c38013d1008584edc0/samples/hello_world/src/main.c#L11
#include <zephyr/kernel.h>

int main(void)
{
	printk("Hello World! %s\n", CONFIG_BOARD);
	return 0;
}
You can also first cd into the directory that you want to build in to avoid typing samples/hello_world all the time:
cd ~/zephyrproject/zephyr/samples/hello_world
zephyr west build -b qemu_x86 -t run
You can also build and run separately with:
west build -b qemu_x86
west build -t run
Another important option is:
west build -t menuconfig
But note that it does not modify your prj.conf automatically for you.
Let's try on another target:
rm -rf build
zephyr west build -b qemu_cortex_a53 -t run
and same output, but on a completely different board! The qemu_cortex_a53 board is documented at: docs.zephyrproject.org/3.4.0/boards/arm64/qemu_cortex_a53/doc/index.html
The list of all examples can be seen under:
ls ~/zephyrproject/zephyr/samples
which for example contains:
zephyrproject/zephyr/samples/hello_world
So run another sample simply select it, e.g. to run zephyrproject/zephyr/samples/synchronization:
west build -b qemu_cortex_a53 samples/synchronization -t run

CIA 2010 covert communication websites / IP and DNS metadata Updated 2025-04-24 +Created 1970-01-01

Some dumps from us looking for patterns, but could not find any.
Sources of whois history include:
The vast majority of domains seem to be registered either via domainsbyproxy.com which likely intgrates with Godaddy and is widely used, and seems to give zero infromation at all about the registrar.
A much smaller number however uses other methods, some of which sometimes leak a little bit of data:
Big question: webmasters.stackexchange.com/questions/13237/how-do-you-view-domain-whois-history DomainTools also has it.
How on Earth did did Citizen Labs find what seems to be a DNS fingerprint??? Are there simply some very rare badly registered domains? What did they see!

CIA 2010 covert communication websites / IP range search Updated 2025-04-24 +Created 1970-01-01
View more
One promising way to find more of those would be with IP searches, since it was stated in the Reuters article that the CIA made the terrible mistake of using several contiguous IP blocks for those website. What a phenomenal OPSEC failure!!!
The easiest way would be if Wayback Machine itself had an IP search function, but we couldn't find one: Search Wayback Machine by IP.
viewdns.info was the first easily accessible website that Ciro Santilli could find that contained such information.
Our current results indicate that the typical IP range is about 30 IPs wide.
E.g. searching: viewdns.info/iphistory and considering only hits from 2011 or earlier we obtain:
Neither of these seem to be in the same ranges, the only common nearby hit amongst these ranges is the exact 68.178.232.100, and doing reverse IP search at viewdns.info/reverseip/?host=68.178.232.100&t=1 states that it has 2.5 million hostnames associated to it, so it must be some kind of Shared web hosting service, see also: superuser.com/questions/577070/is-it-possible-for-many-domain-names-to-share-one-ip-address, which makes search hard.
Ciro then tried some of the other IPs, and soon hit gold.
Initially, Ciro started by doing manual queries to viewdns.info/reversip until his IP was blocked. Then he created an account and used his 250 free queries with the following helper script: cia-2010-covert-communication-websites/viewdns-info.sh. The output of that script can be seen at: github.com/cirosantilli/media/blob/master/cia-2010-covert-communication-websites/viewdns-info.sh.
Ciro then found 2013 DNS Census which contained data highly disjoint form the viewdns-info one!
Summaries of the IP range exploration done so far follows, combined data from all databases above.

CIA 2010 covert communication websites / Wakatime redirects Updated 2025-04-24 +Created 1970-01-01
View more
Summary: this is just a red herring. Wakatime owner likely registered the domains just after this article was published as a publicity stunt. Fair play though.
As raised at: news.ycombinator.com/item?id=36280666, many, but not all, of the domains currently redirect to wakatime.com/ as of 2023, and apparently they were taken up in 2013 (TODO how to confirm that). TODO what is the explanation for that? Some examples that do:
But some failed resolution examples:
Even more suspiciously, according to his LinkedIn: www.linkedin.com/in/alanhamlett/, the owner of Wakatime, Alan Hamlett, worked at WhiteHat Security, Inc from Aug 2011 - Sep 2013. The company was then acquired by Synopsys in 2022. Holy crap!!! As shown at: web.archive.org/web/20131013193406/https://www.whitehatsec.com/ that company made website security tools. Did that dude use the tools to find the vulnerabilty and then just gobble up all the domains??? What a fucking legend if he did!!!
Running e.g.
curl -vvv dedrickonline.com
gives:
*   Trying 162.255.119.197:80...
* Connected to dedrickonline.com (162.255.119.197) port 80 (#0)

so we see that he must have setup redirection with Namecheap as mentioned at: www.namecheap.com/support/knowledgebase/article.aspx/385/2237/how-to-redirect-a-url-for-a-domain/
Let's also try DNS history

So these suggest Alan might have just come along in 2023 way after the 2022 Reuters article and did the same basic IP range search that Ciro is doing now, so possibly no new tech. Let's ask... twitter.com/cirosantilli/status/1668369786865164289
The domain name history presented is however of interest, and could lead to patterns being found.
Searching tools.whoisxmlapi.com/reverse-whois-search with term "Corral, Elizabeth" gave no results unfortunately.
Basic search under tools.whoisxmlapi.com/reverse-whois-search for "Corral" also empty. They can't see their own data? Ah, need advanced. Marked "Historic" and selected "Corral, Elizabeth", ony one hit, activegaminginfo.com.
