DOJ sues Apple, spotlighting iMessage

The U.S. Department of Justice filed an antitrust lawsuit against Apple, claiming the company engages in monopolistic practices over the smartphone market, preventing competitors by degrading the experience of communicating with non-Apple users in its products. iMessage features prominently in the suit, with the DOJ alleging consumers are disincentivized to leave its “walled garden” and so miss out on unique features built into the iMessage protocol, including end-to-end encryption between Apple users.

Controversy over Mozilla’s anti-data broker service

We recently shared news of Mozilla’s partnership with data removal service Onerep. Through a service it calls Mozilla Monitor Plus, Onerep is designed to automatically scan for personal information on data broker websites. But journalist Brian Krebs has found evidence that the founder of Onerep, purveyor of anti-data broker services, himself created dozens of data broker services. Read more.

WhatsApp now supports messages with third-parties

Under the new European Union law, the Digital Markets Act, Meta is required to allow interoperability between third-party chat software and its WhatsApp and Facebook Messenger apps. These tools offer end-to-end encryption using the Signal protocol, the strong encryption specifications pioneered by the Signal encrypted messaging app.

Post-quantum iMessage

Both in the U.S. and abroad, governments are capturing encrypted connections that pass over the public internet and saving them for later use. Within years or decades, post-quantum computers could meaningfully shorten the amount of time required to unscramble encryption, allowing attackers to read previously private messages. So a growing number of organizations, including Apple, are preparing for attacks like these with post-quantum encryption. Read more in our newsletter.

Aye hearties, gangway — the Avast cor-pirates are walking the plank.

Mozilla breaks into the anti-data broker game

Hundreds of data brokers aggregate and sell access to personal data, such as phone numbers, emails, addresses, and even purchasing habits collected through loyalty card programs, social media sites, apps, trackers embedded in websites, and more. Mozilla has a new monthly subscription service which automatically scans for your personal data on data broker websites, but there are other ways to make your data less easily searchable.

Moving from passwords to passkeys

Instead of traditional passwords, where you log into a website with credentials that you know or store in a manager, a passkey is a credential that you store on your device, registered with an online account. Read more in our newsletter.

Journalists targeted with Pegasus yet again

Mercenary spyware firm NSO Group’s Pegasus spyware, designed to remotely access targeted smartphones, is marketed to governments around the world for the purposes of law enforcement and counterterrorism. But in the wild, we’ve seen governments repeatedly abuse this and similar spyware tools to infect journalists, spying on their most sensitive files, communications, and sources.

Harden your iPhone against thieves

Thieves don’t just steal iPhones for the hardware — they may also want access to banking apps and Apple Pay to facilitate fraudulent transfers and purchases. One thing that works in thieves’ favor is that people often use short passwords that are easy to shoulder surf and to memorize — typically only six digits.
