🚚 Deliverables

The whitelists are applied to all the blacklists!

Source Code

🧮 Checksum Evaluation

bash sha256sum CHECKSUMS.txt --strict

The output will print OK if the check was successful. Be sure to run the command in the same directory as the lists!

🐙 Fetching GitHub Releases

Provided below are some examples to fetch release artifacts leveraging the GitHub API.

Get all build artifacts

bash curl --proto '=https' --tlsv1.3 -H 'Accept: application/vnd.github.v3+json' -sSf https://api.github.com/repos/T145/black-mirror/releases/latest | jq -r '.assets[].browser_download_url'

Get a build artifact & its checksum

bash curl --proto '=https' --tlsv1.3 -H 'Accept: application/vnd.github.v3+json' -sSf https://api.github.com/repos/T145/black-mirror/releases/latest | jq -r '.assets[] | select(.name | startswith("BLOCK_DOMAIN")).browser_download_url'

Get a single build artifact

bash curl --proto '=https' --tlsv1.3 -H 'Accept: application/vnd.github.v3+json' -sSf https://api.github.com/repos/T145/black-mirror/releases/latest | jq -r '.assets[] | select(.name | startswith("BLOCK_DOMAIN")) | select(.name | endswith(".txt")).browser_download_url'

🖋️ Manifesto

Please report any hosts or lists that do not align in an issue.

Black Mirror stands on three pillars: privacy, security, and safety.

• Privacy:
  • Whitelist services like trusted torrenting providers, VPNs, and Tor.
  • Blacklist deanonymized telemetry, data brokers, ad redirects, and stalkerware.
• Security:
  • Whitelist services that promote security AND privacy.
  • Blacklist illegal or sketchy sites and known malicious actors.
  • Blacklist advertising to avoid the risks of malvertising.
• Safety:
  • Blacklist deliberate misinformation, irreputable news sources, propaganda, etc.
  • Blacklist vices such as vaping and smoking that cause individual harm.
  • Use GitHub's non-allowance policies at-scale where possible.
  • Acknowledge technological harm, and do what can be done in this project to prevent it.

While Black Mirror censors content beyond privacy and security, it does not seek to do so irresponsibly. Many other popular blacklists say they block specific hosts for certain reasoning, and when combed through turn out to have many false positives, or blocks that fall outside that reasoning. Black Mirror aims to be different by being as transparent as possible. It's open to critique, and encourages community feedback and involvement. The real power behind the freedom of speech is the ability to hear many opinions to quickly deduce those that are correct or reasonable.

“Before you become too entranced with gorgeous gadgets and mesmerizing video displays, let me remind you that information is not knowledge, knowledge is not wisdom, and wisdom is not foresight. Each grows out of the other, and we need them all.”\ ― Arthur C. Clarke

On Spyware/Stalkerware

These services intrude on privacy, are usually malware, and compromise individual safety. Therefore any known parties are blocked.

“There will come a time when it isn't 'They're spying on me through my phone' anymore. Eventually, it will be 'My phone is spying on me'.”\ ― Philip K. Dick

On Propaganda

If it promotes any "knee-jerk contrarian" viewpoints, a website will only be blocked if they are a majority (>50%) of its content. As an example, because we have conclusive evidence on the fact that the Earth is round from the time of Eratosthenes, sites that feature contradictory viewpoints as an opinion majority get blocked.

“True liberty consists only in the power of doing what we ought to will, and in not being constrained to do what we ought not to will.”\ ― Jonathan Edwards

“Make decency cool again.”\ ― Andrew Marantz

On Social Media

The Zuckerburg Institute of Virology

Facebook/Meta

Due to consistent privacy and security concerns, this platform will be blocked.

References

• The Facebook Files

Instagram

Owned by Facebook, but does not have majority support on issues that would get the site blocked. Its trackers and such will be blocked.

WhatsApp

Owned and heavily monitored by Facebook. Communications may be secure between users, but are monitored by Facebook. It also has a track record of significant security concerns. All services will be blocked.

References

• NIST Vulnerabilities

Twitter

Though the cause of most internet drama, this platform is also where many cybersecurity community members communicate and collaborate. While it has compromised privacy and serves personalized ads, the platform itself will remain unblocked to promote cybersecurity communities. Its trackers and such will be blocked.

Reddit

While there are harmful subreddits, they are not in the majority. Many have actually been banned, so this will remain unblocked. Its trackers and such will be blocked.

Snapchat

Largely supports privacy, even though there are some security concerns. It will remain unblocked.

References

• Data Breach Timeline

Tumblr

Blocked due to being largely marginalized with the potential of any subdomain to breach any pillar.

TikTok

Blocked due to countless privacy concerns, regardless of its Chinese affiliations.

🛠️ List Usage

Hosts File

```bash mawk '{print "0.0.0.0 " $0}' BLOCK_DOMAIN.txt >>hosts

mawk '{print ":: " $0}' BLOCK_DOMAIN.txt >>hosts

mawk '{print "0.0.0.0 " $0}' BLOCKIPV4.txt >>hosts mawk '{print ":: " $0}' BLOCKIPV6.txt >>hosts ```

Dnsmasq

Many popular platforms such as OpenWRT, DDWRT, and Pi-hole use Dnsmasq as their choice TCP powerhouse. After inspecting many domain blocklists you'll inevitably run across a list in the dnsmasq.conf format. This list doesn't support it because you can use the addn-hosts parameter to add hosts in the list. Target a file that has the hosts in a format similar to the Hosts File format.

If you're using the RADVD daemon, prepend any listed hosts with ::. Otherwise, even if you have IPv6 support set up, prepend hosts with 0.0.0.0.

This has been tested across all the mentioned platforms using dig{6} on a small sample size and had each host null-routed successfully. DNSmasq's man page discusses configuration further, and DDWRT's ad blocking wiki page provides some examples.

Amazon EC2 DNS Resolver

Follow this guide to create a DNS server on an Amazon EC2 instance.

Pi-hole / personalDNSfilter

Domain list usage is recommended.

Unbound

Similar to dnsmasq, but requires more manual configuration. Name any products as a *.conf file. Then follow Steffinstanly's instructions on how to apply blocklists.

AdGuard

Leverage the ADGUARD_SOURCES.txt list or the domain list.

🐋 Docker Usage

Temporary Container

bash docker container run -u 0 -it --rm -h black-mirror ghcr.io/t145/black-mirror

Persistant Container

bash docker container run -u 0 -it --name black-mirror -h black-mirror ghcr.io/t145/black-mirror

Then to access the container at a later date, run:

bash docker start black-mirror docker exec -u 0 -it black-mirror /bin/bash

Building the Image

bash docker build --no-cache --progress=plain -t black-mirror .

👨‍💻 Development

Workspace Setup

Install Docker, PNPM, and NodeJS. These can usually be installed with a popular package manager. The specific Node version used in this project is provided in .node-version, but any version over 16 should work. With Docker running in the background, execute pnpm lint to debug any changes.

🛡️ Privacy Protectors

Good causes that help secure your digital life.

• Stop using Cloudflare!
• Use a pcWRT to easily secure your internet!
• Test your browser's tracking resilience with CoverYourTracks!
• Explore PrivacyGuides and Prism Break to discover services that respect your privacy!
• Use the Web Archive or Bypass Paywalls Clean to access restricted and useful information, such as the WSJ's Facebook Files.
• Skip over URL shortener links by using Unshorten.it, which is a better alternative to outright domain blocking.
  • Review their privacy policy.
