The Mac-infecting Realst crypto stealer is back. It’s been over a year since the malware emerged as a tool for cybercriminals to drain cryptocurrency from wallets and steal other credentials. It was initially disseminated through fake blockchain games, as I reported at the time. However, it now appears to be directed at Web3 developers in a targeted spear-phishing campaign.

Last week, I received an interesting report from the security research arm of the popular Apple device management software firm Jamf that detailed a serious but now-patched iOS and macOS vulnerability. The finding was under embargo, but today, I can finally talk about it.

Jamf Threat Labs uncovered a significant vulnerability in Apple’s iOS Transparency, Consent, and Control (TCC) subsystem on iOS and macOS that could allow malicious apps to access sensitive user data completely unnoticed without triggering any notifications or user consent prompts.

Security Bite: Why email security is still so bad

Apple mail app email

It’s a little-known fact that before emails reach your inbox, they pass through a buffer designed to scan and block malicious content. However, over time, email providers—especially Gmail—have shifted their focus to just adding “warning labels” to those with suspicious links or attachments. This approach, best described as “beating around the bush” hasn’t reduced threats much at all. Shockingly, 91% of all cyberattacks still originate from emails. So, what gives?

This week, I want to share a fascinating talk I came across on social media about an Apple service that doesn’t seem to get as much attention in the community: CarPlay. While Apple has not publicly disclosed the exact number of CarPlay users, I’d venture to say it’s one of its most used services. And one of the biggest concerns is anything that could compromise driver safety or privacy. So, how secure is CarPlay?

Private Cloud Compute (PCC), the computational powerhouse behind Apple Intelligence, was unveiled months back at WWDC24 as Apple’s new privacy-focused cloud infrastructure. At the same time, the company stated it would periodically release subsets of PCC source code for independent review. After some wait, 9to5Mac reported last week that many of its resources are now available to everyone. Here’s what’s included.

For years, Apple provided its built-in Keychain password management tool hidden within the Settings app. This tool allowed passwords to be automatically generated and saved in the Passwords section, but it could often be cumbersome when a user wants to manage particular logins.

Now, in iOS 18, iPadOS 18, and macOS Sequoia, saved passwords have broken away into their own rounded corner island on the home screen called Passwords. Apple hopes this new app will make managing credentials more convenient for users. However, there are concerns that it may not offer enough features to replace paid password managers. Sure, but is that the goal?

In possibly a first since the release of macOS Sequoia, cybersecurity researchers have identified a new attack vector that sidesteps the usual “right-click, open” in favor of something rather unusual. In a recent finding shared on social media, this new method involves tricking users into dragging and dropping malicious code (via a .txt file) directly into the Terminal.

MacPaw releases major update to CleanMyMac with fresh design and new features

MacPaw CleanMyMac

MacPaw has unveiled a major (and shiny) new update to its flagship product, CleanMyMac, a go-to app for optimizing, cleaning, and protecting Macs. The first thing you’ll notice is that the sidebar has been dramatically simplified to just six main modules for easier navigation.

However, this didn’t come at the cost of new features. Along with a redesigned interface, CleanMyMac now comes packed with more personalized Mac Health reports, enhanced privacy protections, and smart optimization tools, like duplicate file management.

I’m in the midst of traveling to Ukraine this week for OFTWv2.0, and I can’t help but think about the comments on last week’s edition of Security Bite defending the VPN apps that still exist on the App Store in Russia. While almost every app from legitimate providers in the country has been removed, Russian users can still find a surplus of VPN options claiming to offer secure encryption and private browsing. The only question being–really?

Since Russia’s full-scale assault on Ukraine, Apple has significantly scaled back its operations in the country. It has since suspended all product sales and limited certain services, such as Apple Pay. Despite this, Apple continues to operate a full-fledged App Store in Russia. However, it’s now facing worthy criticism for complying with Russian government requests to remove VPN apps to adhere to local regulations–censorship.

On Monday, Apple released its latest iteration of Mac’s operating system, macOS Sequoia. The new update introduced tighter control over app permissions and an overhaul to Gatekeeper, among other features. However, according to TechCrunch, it now appears to be disrupting security tools made by CrowdStrike, SentinelOne, and Microsoft. Social media users are also reporting connection failures with third-party VPNs.

Update (10/2): Thursday’s release of macOS 15.0.1 fixes the underlying networking issues that plagued certain security software in the initial release of macOS 15.

The privacy implications of Notification Center popups are well-known in the security forensics community. Whether a user likes it or not, macOS temporarily keeps a log of every notification received in a single plaintext database. This can include messages from applications like iMessage, Slack, Teams, and virtually anything else.

However, it now appears Apple has moved the Notification Center database in macOS Sequoia to address concerns.

You’ve heard it time and time again–cybercrime is on an unpredicted rise. This encompasses everything from malware to online scams to intellectual property theft. And if you’re anything like me, it’s increasingly hard to grasp the exponentially climbing figures (hence the title of this week’s column). If the day ends in y, there’s some sort of data leak or hack in the news.

And it is Sunday, after all…

In today’s Security Bite, I want to again shed light on a recent Statista Market Insights survey that predicts the annual cost of cybercrime globally will reach $10.29 trillion by 2025. For perspective, that’s more than one-third of the United States’ GDP, which sits at $25.44 trillion as of writing.
