In June 2023, the UK government announced its proposal to expand its surveillance powers by, among others, forcing communications operators to undermine encryption or abstain from providing security software updates globally. Building on our response to the government’s plans, this piece explains why what they want to do puts every one of us at risk.
Why your trust (to technologies you use) matters
Surveillance and privacy are complex concepts to grasp – it’s part of the appeal to us at PI.…

First published in 2017, “PI’s Guide to International Law and Surveillance” is an attempt to collate relevant excerpts from these judgments and reports into a single principled guide that will be regularly updated. This is the third edition of the Guide. It has been updated it to reflect the most relevant legal developments until December 2021.Despite its name, the Guide isn’t just aimed at lawyers. It aspires to be a handy reference tool for anyone engaging in campaigning, advocacy, and…

Zoom said it would deliver end-to-end encryption as one of a number of security enhancements to its service, but it will only be available to enterprise and business customers whose identity they can verify and not on the free service. The company says it wants to be able to work with law enforcement in case people use Zoom for a "bad purpose". None of Zoom's competitors offer end-to-end encryption.

The controversial Israeli spyware company NSO Group's US arm, Westbridge, has been trying to pitch its phone hacking software to US law enforcement agencies such as the San Diego Police Department, particularly a tool called "Phantom", which the complany claims can overcome encryption, track geolocation, withstand a factory reset, monitor apps and voice and VOIP calls, and collect passwords.

Bluetooth utilizes a device pairing mechanism based on elliptic-curve Diffie-Hellman (ECDH) key exchange to allow encrypted communication between devices. The ECDH key pair consists of a private and a public key, and the public keys are exchanged to produce a shared pairing key. The devices must also agree on the elliptic curve parameters being used. Previous work on the "Invalid Curve Attack" showed that the ECDH parameters are not always validated before being used in computing the resulted…

An engineering and computer science professor and his team from The Ohio State University discovered a design flaw in low-powered Bluetooth devices that leaves them susceptible to hacking.
Zhiqiang Lin, associate professor of computer science and engineering at the university, found the commonly used Bluetooth Low Energy devices, such as fitness trackers and smart speakers, are vulnerable when they communicate with their associated apps on the owner’s mobile phone.
"There is a fundamental…

Everyone is talking about Facebook's end-to-end encryption plans and the US, UK and Australian government's response. Feeling lost? Here is what you need to know.
What's Facebook trying to do?
First let's be clear: Facebook has many faults when it comes to privacy. It's also suffered a number of security failures recently. See here for instance.
In response to their successive failures to protect your privacy, Facebook announced in their 'pivot to privacy…

Today’s announcement regarding the UK and US agreement signed pursuant to the US CLOUD Act is being touted on both sides of the Atlantic as a major victory for law enforcement and security. But it is a step backward for privacy.
And it’s far more complicated than their press release and letter to industry.
The agreement replaces the prior system, under which law enforcement agencies from around the world, including the UK, had to meet US legal standards in order to get access to content held…

Privacy International has joined a global coalition of privacy campaigners, tech companies, and technology experts to respond to proposals by British intelligence chiefs aimed at allowing them access to encrypted messaging apps such as WhatsApp or Signal.
If implemented, the proposals would allow government authorities to force messaging platforms to silently add a law enforcement participant to a group chat or call.
Such a capability poses serious threats to…

In February 2019 Google engineers announced that they had created faster, more efficient encryption system that could function on less-expensive Android phones that were too low-powered to implement existing full-device encryption. The scheme, known as Adiantum, uses established and well-vetted encryption tools and principles. Android has required smartphones to support encryption since 2015's version 6, but low-end devices were exempt because of the performance hit. It will now be up to device…

Background
Email is hard to secure. For years we've been trying to build security on top of email, such as through technologies like Pretty Good Privacy (PGP) and the open source implementation: GnuPG (GPG).
What happened
In the past 48 hours, there have been very scary looking reports recommending people switch off PGP in their email clients.
The TL;DR version of this post is:
PGP is not broken by this attack
You absolutely should not stop…

Dear Politicians,
With elections coming up and quite a few cringe-worthy comments that have come from many of you and from all sides of the political spectrum, we figured it was time to have a chat about encryption.
First, let’s say what you shouldn’t do:
call for boycotts of companies because they protect their users’ data even from the companies themselves.
say something like “we’ll develop a Manhattan-level project on this” (which, as we’ll remind you, ended up with the creation of a…

Technologists hoped the “Crypto Wars” of the 1990s – which ended with cryptographers gaining the right to legally develop strong encryption that governments could not break – was behind them once and for all. Encryption is a fundamental part of our modern life, heavily relied on by everything from online banking and online shopping services to the security our energy infrastructure.
However, from comments by the French and German governments about creating a European initiative to circumvent…
