Events in this calendar are to privacy-related events. Click an event for more details, and links.
- AZ Supreme Ct. rules Internet users have no reasonable expectation of privacy for the information available to their ISPs - No warrant required means the risk to privacy for ordinary, innocent people increases. Fitting a pattern, a case about child exploitation is leveraged for wide impact. See tips below on using Tor or VPNs to secure your information from your ISP.NEW
- 4th Circuit Ct of Appeals to take up challenge to use of Military Wide-Area Persistent Surveillance technology in Baltimore - Increasing use of WAPS is mentioned below multiple times; this is part of a history.
- WhatsApp pulls a switcheroo - Facebook (owner of WhatsApp) now gets your phone number, among other things.NEW
- Police Departments around Tucson now do have agreements with Ring - See below for earlier news on this. An up to date record of police requests for video from private users of Ring doorbells here
- Apple's official guide to avoiding abuse of iOS features - Addresses problems of stalking, IPV, and other cases where personal safety is at risk.
- Mozilla argues against antitrust Google case - Not mentioned, but by now well-known: Mozilla gets the lion's share of its funding from an arrangement to have Google as the default search engine in Firefox.
- Key protecting Intel microcode extracted - These guys used their Intel Management Engine exploit to do it, which is mentioned below from a few years back (they presented it at Blackhat 2017).
- "Justice Department Sues Monopolist Google For Violating Antitrust Laws: Department Files Complaint Against Google to Restore Competition in Search and Search Advertising Markets" - That's the title. New issues compared to the FTC's look back in 2013, which involved five Attorney's General disjoint from the eleven cited by DoJ.
- GPG has an important update - Affects versions found in most package managers.
- EARN IT Act passed Senate, introduced into the House - EARN IT attempts to weaken encryption for US companies who want liability protection under 230; opens politicians who opposite it to the charge they're on the side of child predators. A similar bill, the Lawful Access to Encrypted Data Act, is more honest.
- Internet archive sued - Publishers sue during the pandemic to shut down an organization that tried to help. Thanks a lot, guys!
- Military aerial surveillance technology deployed in Baltimore - High resolution, persistent capture of images of large areas of a city. Developed for use in Fallujah, brought to Dayton, OH and Baltimore, MD pbs coverage, Radiolab on the first time this happened, PSS, a company doing WAPS
- List of third parties with which Paypal shares payment information - Used to be around 600 names; I haven't counted the updated numbers
- Transparency report about records collected under 702 has been released
- Facebook makes suckers lists easy - FB allows targeting based on interest in "pseudoscience," is called out on it, and takes it down, completing a cycle that has repeated many times before (see: targeting "jew hater").
- Police Departments around Tucson appear not to have agreements with Ring
- 77 day extension passed for the USA FREEDOM Reauthorization Act kicks the can to May 31st.
- Recent dust-up over FBI access to databases of records collected under 702.
- Wireguard to be included in the next Linux kernel
- Private Internet Access (PIA) is now owned by a company with questionable past - The company, formerly called Crossrider, was responsible for scads of adware.
- Startpage.com is now owned by an advertising company - Tough to trust them in the future. Consider search.disroot.org
- The trouble with Cloudflare. Blocks Tor, blocks bots (even good ones), MiTMs connections and can break TLS. Unknown history with DHS following overtures to Cloudflare's previous incarnation, Project Honeypot.
- OSTIF will audit Unbound DNS
- HTTPS interception -- Around 15% of HTTP connections over TLS are being intercepted, according to the traffic sample (about 10%) visible from Cloudflare. Maybe the green lock should turn orange-ish?
- Mark Zuckerberg's "Privacy-Focused Vision" -- "Privacy gives people the freedom to be themselves and connect more naturally, which is why we build social networks." FB was built not for your freedom, but to make money selling ads. Confidential messaging makes you feel safe, but all of FB's bad privacy practices are made more effective by that feeling, not less.
- Breach of Amadeus affecting millions of airline travelers.
- Londoners on the perpetual line-up -- Being "in public" seems to have an evolving meaning. See also the US.
- Report on the mistakes leading to the Equifax breach of 148 M records -- From the House Committee on Oversight and Government Reform. Makes you wonder if banks (and others) might compete on being less profligate "furnishers" to CRA's---maybe discriminating among CRAs by their security and privacy practices (Equifax got 0 out of 10 for these from the financial index provider MSCI here). I'd prefer a bank that did that.
- AI Now Institute issues an "urgent warning" about privacy threats from AI. -- The article and warning are problematic, but there is this bright spot from the news article on it: "'artificial intelligence' — an umbrella term that includes a myriad of both scientific attempts to simulate human judgment and marketing nonsense"
- McSweeney's End of Trust issue is available free from the EFF (but do support them for creating this great work)!
- Tim Berners-Lee's Solid project is maturing; there is now a start-up (Inrupt) developing it

- California joins Illinois as among the most privacy-protective states in the US.
- IEEE is also against exceptional access
- Big privacy win in Carpenter v. U.S.
- James Clapper and James Comey make appearances to promote their books. Jim Comey is on Conan, James Clapper is on 1A on NPR (44:10 is funny), and All Things Considered on NPR.
- Spate of leaks: Grindr (which, with OPM breach, could lead to blackmail of government employees, not unlike Ashley Madison); Panera Bread; Facebook; Myfitnesspal. Consider giving an alias rather than a real name to services online (which is perfectly legal, as long as you don't use it for fraud), spamgourmet.com for addresses, privacy.com for credit cards
- Privacy fundraiser underway where DuckDuckGo will match donations!
- Mixpanel analytics, present on a zillion sites, takes in passwords on some of them
- Carpenter v. US, a SCOTUS case in which the government is arguing that owning a cell phone means your physical movements can be tracked, is now underway.
- Extent of AT&T is greater than expected (billions of emails, all communications at the UN headquarters, 1.1 billion domestic call records per day, etc.). This is all from further study of the Snowden revelations, it looks like.
- European court of human rights to rule on UK surveillance. -- Includes claim that only "sentient examination" of data violates privacy. See the NSA on 'collection' for a similar argument.

- Lavabit returns. How does it compare to protonmail, or mailpile? Let me know; I haven't looked into it.
- All US visitors from Muslim majority countries soon may have to give up social media passwords to enter Given rapidly eroding rights at the border, everyone should see what you can do at the link in this section below
- WhatsApp has an in-effect-backdoor by default. The justification for failing to provide security by default is that "otherwise people might not use it," ignoring that run-of-the-mill users of WhatsApp might falsely believe that promises of end-to-end encryption for their messages means that those messages cannot be intercepted.
- Google and government, via the Google Transparency Project. Google lobbies to influence policy to reduce consumer privacy. This article also discusses the NSA-Google relationship.
- Riseup warrant canary expires, Riseup is alerted, but the canary is not updated.
- FBI now can compromise computers outside the jurisdiction of the court issuing the warrant, including overseas.
- Trump pick for CIA head, Mike Pompeo, says in the Wall Street Journal that "the use of strong encryption in personal communications may itself be a red flag" that a person is a terrorist.
- Extreme surevillance via "Snooper's Charter" is now law in the UK. Among other things, requires internet providers to log websites that their customers connect to.
- FCC requires customer opt-in for ISPs to share "sensitive data", opt-out for "other" data. Previously there was no regulation)

- Cybersecurity Sharing Act added at the last minute to a 2K page omnibus spending bill
- police and drone use in Baltimore
- U.N. Report on Encryption as a right. "... [T]he present report examines two linked questions. First, do the rights to privacy and freedom of opinion and expression protect secure online communication, specifically by encryption or anonymity? And, second, assuming an affirmative answer, to what extent may Governments, in accordance with human rights law, impose restrictions on encryption and anonymity?"
- CMU study supports that Google cannot police abuse of its ad system, resulting in violation of privacy
- CEO of Hacking Team interviewed on BusinessInsider
People often tell me they are unsure about which privacy-enhancing technologies to use, and how to set them up. Here are some suggestions.
secure hardware elements
- Qubes ...OK, not an OS... (also here is a brief description of getting wireless networking working)
- OpenBSD - Great documentation, elegant base system, fast response to security bugs. Great for firewalls , for example, but also more and more suitable for general use.
- the machine-id is a more stable identifier than other things that could be used as stable identifiers. There are other ways to identify a machine, of course, but this one is stable and easy to get in a variety of ways. Resetting it is no big deal, though (and can be done without the "unpredictable consequences" mentioned without explanation in the link)! Follow these instructions. Devuan, a systemd-free fork of Debian, patched this. The instructions here assume systemd).
- Psiphon - I don't know how good this is yet. Here's a contributor talking about it at the latest CCC.
- Lantern - I don't know how good this is yet
- Tor (see below)
- Mullvad VPN -- A good vpn. Update: Privacytools.io agrees.
- OpenVPN's latest version was audited, which helps with trustworthiness -- If you run your own VPN (which is easy), this is a good reason to make sure you're using 2.4.2 or better (I had to compile from source, as the packages aren't up to date).
- Set up an alias, with associated accounts. This is perfectly legal as long as you don't use it for fraud, as Julia Angwin notes in her article for Consumer Reports.
- Tor -- I suggest subscribing to the RSS feed of the blog of the Tor project to be sure you stay up to date.
The hardened version of Tor has been discontinued; the Tor project recommends moving to the sandboxed version for increased security.As of Tor 8.0, the sandboxed Tor is no longer a separate thing; download the experimental version (>8.0) to get the benefits.
- Also who uses Tor?
- Tor Browser for everyday Use a second installation of the Tor Browser for everyday browsing without connecting to tor. Very actively maintained (better than regular FF); works great. Why do this? A big reason is TB has much, much better fingerprinting protection.
- Related: Tor is one of the few browsers to block the prolongation attack that allows tracking using TLS. Test it here, (check under "Protocol Details" to see if "Sessions tickets" is yes.)
- A fun and useful thing to do is build your own browser to scratch your own itch. For example, if you don't like some CAs after the DarkMatter fiasco, you might rip them out (just saying). It's unfortunately kind of annoying to figure out how to do it, but fortunately I've already done that: see here. NEW
- Changing search providers in Firefox and Tor Browser without 'search addons" etc. is an indefensible PITA. Here's how to do it: if you have rid yourself of the cruft that is the separate search bar to the right of the address bar---as all people of sound mind and good will have done---then temporarily add it in using the 'Customize...' option (right-click on an empty area to the right of the tabs to see 'Customize...', drag the search bar next to the address bar). Now go to a search engine site---currently I like searx, one instance is searx.me---, and click the magnifying glass icon with the green plus, then click "add 'searx.me'). Now go to your preferences (Edit->preferences, or Alt-E, N if you don't have a menu bar) and set your default search provider to the new one you added. Finally do the customize rigamaroll again, but drag the superfluous search bar off. Wasn't that easy?!
- Why not Chrome/Chromium? -- It does have a sandbox, but it is also the most privacy invasive browser (of the major ones). Also Google controls the extensions for it, and they are sometimes unjust.
these all work with Tor Browser, Icecat, or (vanilla) Firefox.
- Try blackhole-ing tracking domains with this handy list, formatted for ready inclusion in your /etc/hosts file from the trackers listed in the Exodus ETIP (shoutout to the Yale Privacy Project contributions). Now visit a site and watch the 0B transfers flow.
- Random Agent Spoofer (blocks a variety of fingerprinting attacks)
- RequestPolicy (By Justin Samuel and Beichuan Zhang, of University of Arizona!)
- PrivacyBadger (EFF)
- Self-Destructing Cookies
- HTTPS Everywhere (EFF)
- BetterPrivacy (removes LSO's -- supercookies -- which survive normal cleaning of cookie cache)
- decentraleyes - runs CDN scripts locally, rather than using remote CDNs (which is trackable)
- Privacy Settings (the plugin) -- Gives quick access to useful privacy settings in the browser, with toggle switches.
- Update Scanner -- Useful for watching privacy policies for changes (since that is your obligation, as a continuing user of the site. Often such changes are not highlighted; only a new version is posted).
testing for problems
- Check whether you have "safe browsing" features turned on. -- Firefox sends 32-bit prefix hashes of your URL to Google as a "safety" measure. I don't recommend using this (and related) features, since the problem with Google is bigger than the security one this mechanism is trying to solve. So if you get a warning visiting this page, investigate how to turn off "safe browsing" features here.
- new fingerprint checker, targeting Tor users in particular
- new fingerprinting technique Uses AudioContext and getClientRects. Recommended defense is NoScript.
- dns leak test -- Test whether you're leaking DNS information while on your VPN, and fix it
- Facial Weaponization Suite - More privacy protest than technical countermeasure. "Collective masks" from aggregated face data of participants in workshops.
- Hyperface Much like Glamouflage, designed to drive up false alarms in facial recognition. Update:
available in August.Delayed, with no deadline given
- Reflectacles try to ignore the goofy promo. video :-)
- Privacy Visor - Can be purchased by emailing this address at Nissey Co., Ltd.
- CV Dazzle
- Russian artists are still trying to use this. Does not work on human cops, who arrest them.
- OTR is not a great idea - OTR became well known after a few high-profile uses, but nowadays it's not a great idea. Biggest problem is forward secrecy, especially since quantum computing is not a question of if, but when. I disagree with one of the article's alternatives, Signal, since it's centralized and coerce-able, but some OMEMO implementations are OK (more on that soon). NEW
- Standard SKS servers for PGP keys are broken, use Hagrid servers instead - A good one to use to keep your keys up to date (see parcimonie, below) is keys.openpgp.org.
- Security freeze for great good -- Prevent not just identity theft, but resale of your data by the Credit Reporting Agencies with a security freeze.
- Keep your PGP keys up to date, privately -- Parcimonie updates your keyring over tor (catching revocations and expirations), at random intervals. It leaves open a connection to tor for a long time, so you may want to run it as a cron job and kill it after some interval.
- anonymize scanned printouts from printers using tracking dots. From TUD, where lots of useful privacy tools have been created (kudos)
- Protecting against baseband firmware backdoors, and provider backdoors-- A little outdated, but still full of good stuff. This is a comprehensive approach; for specific tools see below. EDIT: RIP Copperhead OS.
- Silence SMS/MMS. Recommended -- Mark Zuckerberg says: "many people use Messenger on Android to send and receive SMS texts. Those texts can't be end-to-end encrypted because the SMS protocol is not encrypted." Well, I guess I wouldn't expect much understanding of privacy tech from Mr. Zuckerberg.
- Noise is just like Signal, but without the hard dependency on Google Play Store. It is therefore better! But Silence is better still...
- Get an RSS feed reader to keep up to date on privacy-related sites. For example *cough* subscribe to the PrivacyGroup's feed (It's good to use a secure RSS reader. For mobile there is Courier from The Guardian Project).
- Youtube-dl -- Downloads a variety of streaming formats -- not just for youtube! Can be used with torify (see below) to anonymously view streaming video/audio that otherwise compromises privacy (e.g., flash). Note the version in packages is often not up to date--install the latest with pip to get a version that actually works.
- Torify -- A SOCKS proxy to the Tor network, and a wrapper to use it, so you can e.g. look up GPG keys, or perform WHOIS queries, anonymously.
- Get a GPG key
- installing the latest GPG
- Get a Gnuk token! -- Good way to do encryption in a protected dedicated device. You can buy them, or build them yourself
- secure SSH
- Using gpg-agent instead of ssh-agent
