Or how to avoid getting locked-out of another Google Account
This guide will describe how to setup a persistent browser (for Evil Corp) that’s isolated in a sandbox (with firejail) and forced to use a SOCKS5 proxy to retain a static IP address (using proxychains)
Have you ever been locked out of your own account, and then got an email for your service provider annoyingly letting you know that they’ve “blocked a login attempt — for your protection?“
There’s countless reports of frustrated users who have permanently lost access to their own gmail accounts because of Google’s faulty “fraud protection” systems that locked the account owner out of their own account, due to false-positives.
Problem
Especially the past 10 years, large corporations have been using machine learning anomaly detection systems on their login pages. Unfortunately, sometimes this is (ab)used to have priority over credential authentication challenges.
Even if you enter your username, password, and 2FA credentials correctly on the very first login attempt, you may get locked out of your own account because you “look different”
I’m super happy that Techlore invited me on their YouTube channel to talk security and privacy 😀
Henry was mostly interested in my work with BusKill (an open-source dead man switch), but our conversation ran a gamut of issues regarding security and privacy — including
How to mitigate State-sponsored interdiction attacks, minimizing attack surfaces of mobile phones with broadband processors, the threats of AI “identity verification” systems on privacy, and much more

This article will show how to check if a given Onion Service (ie some .onion address) is alive or dead.
Why?
Lots of Onion Services are “here today, gone tomorrow”. If you encountered a large list of Onion Services and want to quickly check to see which are still alive, the best way to do that is by querying the Tor network’s Hidden Service Directory (HSDir).

This article introduces the concept of “3TOFU” — a harm-reduction process when downloading software that cannot be verified cryptographically.
⚠ NOTE: This article is about harm reduction.
It is dangerous to download and run binaries (or code) whose authenticity you cannot verify (using a cryptographic signature from a key stored offline). However, sometimes we cannot avoid it. If you’re going to proceed with running untrusted code, then following the steps outlined in this guide may reduce your risk.
TOFU
TOFU stands for Trust On First Use. It’s a (often abused) concept of downloading a person or org’s signing key and just blindly trusting it (instead of verifying it).
3TOFU
3TOFU is a process where a user downloads something three times at three different locations. If-and-only-if all three downloads are identical, then you trust it.
Why 3TOFU?
The EFF’s Deep Crack proved DES to be insecure and pushed a switch to 3DES.
During the Crypto Wars of the 1990s, it was illegal to export cryptography from the United States. In 1996, after intense public pressure and legal challenges, the government officially permitted export with the 56-bit DES cipher — which was a known-vulnerable cipher.
This article will present a few simple website availability monitoring solutions for tor onion services.
Problem
So you’ve just setup an Onion Service for your website, but how often do you actually check that it’s working? Maybe it’s a .onion alias to an existing website, and you usually only check it on the clearnet. What’s to prevent the darknet presence of your website from going down for weeks without you noticing?
Indeed, it’s important to monitor your .onion websites so that you can discover and fix issues before your customers do. But how? Most of the popular uptime monitoring solutions (pingdom, freshping, statuscake, etc) certainly can’t monitor .onion websites.
This guide will enumerate some solutions for monitoring .onion websites, so you get an email alert if your site goes down.

This article will describe how to point a .onion domain at your existing wordpress sites (on wordpress multisite) so that your website will be accessible both on the clearnet and directly on the darknet via a .onion domain.
Intro
There are numerous security benefits for why millions of people use tor every day. Besides the obvious privacy benefits for journalists, activists, cancer patients, etc — Tor has a fundamentally different approach to encryption (read: it’s more secure).
Instead of using the untrustworthy X.509 PKI model, all connections to a v3 .onion address is made to a single pinned certificate that is directly correlated to the domain itself (the domain is just a hash of the public key + some metadata).
Moreover, some of the most secure operating systems send all the user’s Internet traffic through the Tor network — for the ultimate data security & privacy of its users.
In short, your users are much safer communicating to your site using a .onion domain than its clearnet domain.
For all these reasons, I wanted to make all my wordpress sites directly available to tor users. Unfortunately, I found that it’s not especially easy to point a .onion domain at . . . → Read More: WordPress Multisite on the Darknet (Mercator .onion alias)
This website is now accessible on the darknet. And how!
Why
Fun fact: the most popular website on the darknet is facebook. There are hundreds of other popular sites on the darknet, including debian, the CIA, the NYT, the BBC, ProPublica, and–now–michaelaltfield.net.
All of these organizations chose to make their websites available over .onion addresses so their website will be accessible from millions of daily tor users without leaving the darknet. Besides the obvious privacy benefits for journalists, activists, cancer patients, etc — Tor has a fundamentally different approach to encryption (read: it’s more secure).

This article is a part 3/3 of a series describing how to setup an Ephemeral Firefox session as a Site-Specific Browser. The ultimate goal is to be able to have a self-destructing browsing session that can only access a single company’s services, such as Google or Facebook.
Part 1/3: Ephemeral Firefox in Ubuntu Part 2/3: Ephemeral Firefox with Extensions Part 3/3: Ephemeral Firefox as a Site-Specific Browser
After setting up the Site-Specific Ephemeral Firefox Browser, you can then blacklist services designated to your Site-Specific browser(s) (such as Google or Facebook) from your main browser. This significantly improves your ability to browse the internet without your activity being tracked by these companies — leaving your sensitive data vulnerable to being stolen by hackers.

Whonix 14 just came out last month. I went to update, but I couldn’t figure out what version I was currently running. The documentation said to run this command, but the output didn’t make sense when I ran it on my whonix-gw TemplateVM.

This article will introduce a tool to detect censorship or network tampering using the Open Observatory of Network Interference (OONI) android app, which is part of the Tor Project.
The OONI project’s mission is to collect data on network providers to determine where the Internet is free and where it’s being manipulated. For example, the OONI Explorer displays a world map of such data.
On the OONI explorer, you can drill-down on the world map into a specific country to get a list of websites that were detected as being blocked from within that country.
For example, when I looked at the history of OONI probe runs within the US, I saw a list of the usual suspects: gambling sites, pornography sites, torrenting sites, etc. More surprising (at least to me) was the number of pastebin sites that were banned. And, despicably, there was a network in the US blocking The Internet Archive
When I looked at the data from scans within another great “free country” = India, I saw a lot of cherry-picked censorship on facebook and news articles as it relates to the 2017 genocide of Rohingya Refugees in Burma and various muslim/hindu conflicts.
