Update, November 1, 10:59 a.m. ET: Apple has removed the sketchy ChatGPT clone app mentioned below. I’ve also received unverified claims that many other copycats have been taken down too.

Around this time two years ago, OpenAI’s incredibly popular GPT-4 API was spreading like wildfire all over the App Store. It wasn’t long before AI-powered productivity apps, chatbot companions, nutritional trackers, and basically anything else you could think of dominated the charts, garnering millions of downloads. Fast forward to today, many of those vibe-coded, opportunistic apps have disappeared, partly due to cooling hype but also Apple’s tougher stance against knockoffs and misleading apps.

However, this week, security researcher Alex Kleber noticed that one misleading AI chatbot, impersonating OpenAI’s branding, managed to achieve top marks in the Business category. Albeit on the less popular Mac App Store, this is still significant and warrants a brief PSA to be cautious when sharing personal information with these apps.

In this week’s Security Bite, I’m taking it back over 20 years to the launch of Gmail in 2004–because that’s how long its little-known plus addressing (aliasing) feature has quietly existed. It was originally created to help with filtering and keeping inboxes tidy long before spam became what it is today. Google never really promoted it, so most people still don’t realize it’s a thing. But over the years, it’s become popular among privacy-minded folks to track which online services, subscriptions, etc., are selling email addresses to other companies or leaking them.

The British government is still insisting Apple must create a backdoor into iCloud | Low-key photo of eyes peering from the darkness

We learned back in February that the British government had secretly ordered Apple to create a worldwide backdoor into iCloud. We said at the time that the demand was “as technically clueless as it is outrageous.”

Apple responded very intelligently, and it seemed from a development last month that the UK had withdrawn its demand. We’re learning today that this isn’t in fact the case …

Earlier this year, Apple announced that it was leading the charge on a cross-industry effort to bring end-to-end encryption (E2EE) to the RCS Universal Profile, which is published by the GSMA. Apple told 9to5Mac in March it would come to the iPhone in a future software update. Google soon after jumped in, stating it too was ‘committed to providing a secure messaging experience.’

I didn’t think it was completely unreasonable to assume we’d see this showcased at WWDC 2025…that didn’t happen. Then I thought maybe in one of the iOS 26 betas? Also nothing. So, what happened to cross-platform E2EE for RCS messaging? Is it still coming?

Do you need third-party anti-virus software on a Mac?

Do you need third-party anti-virus software on a Mac? | Close-up of older MacBook with illuminated Apple logo

For many years, it was accepted wisdom that Mac malware wasn’t really an issue. One of the reasons for that was that the market share was simply too low to make it a worthwhile target for attackers.

Today, of course, is a very different world. Macs are the fourth most popular brand of personal computers, and as owners of a premium brand, Mac owners make a juicy target. Does that mean you need third-party antivirus software on a Mac, or are the built-in security protections good enough? A very thorough test sought to find out …

After warning 9to5Mac last month about undetectable Mac malware hidden in a fake PDF converter site, Mosyle, a leader in Apple device management and security, has now uncovered a new infostealer. Dubbed ModStealer, the malware has remained invisible to all major antivirus engines since first appearing on VirusTotal nearly a month ago.

In details shared exclusively with 9to5Mac, Mosyle says ModStealer doesn’t just target macOS systems, but is cross-platform and purpose-built for one thing: stealing data.

If you’re reading this week’s Security Bite on your desktop, look closely at your browser’s address bar. Notice how the main (root) domain is bolder, while the rest of the URL is a lighter grey? This is not an accident, it’s a purposly implemented psychological trick called salience bias. This little design choice has protected users from phishing attacks for over a decade.
