Analyzing a watering hole campaign using macOS exploits
To protect our users, TAG routinely hunts for 0-day vulnerabilities exploited in-the-wild. In late August 2021, TAG discovered watering hole attacks targeting visitors to Hong Kong websites for a media outlet and a prominent pro-democracy labor and political group. The watering hole served an XNU privilege escalation vulnerability (CVE-2021-30869) unpatched in macOS Catalina, which led to the installation of a previously unreported backdoor.
Why is the Zoom app listening on my microphone...
I'm running MacOS Monterey. Several times in the last few weeks, I've noticed the orange dot indicating the microphone is being used by an app, and I click on the Control Center and see that Zoom is accessing the microphone. I'm not in a meeting and simply have the Zoom app open. Why would Zoom be accessing the microphone when I'm not in a meeting?

Analysis of a new macOS Trojan-Proxy
A new macOS Trojan-Proxy is riding on cracked versions of legitimate software; it relies on DNS-over-HTTPS to obtain a C&C (command and control) address. Illegally distributed software historically has served as a way to sneak malware onto victims’ devices. Oftentimes, users are not willing to pay for software tools they need, so they go searching the Web for a “free lunch”. They are an excellent target for cybercriminals who realize that an individual looking for a cracked app will be willing to download an installer from a questionable website and disable security on their machine, and so they will be fairly easy to trick into installing malware as well.
N. Korean Hackers 'Mixing' macOS Malware Tactics to Evade Detection
The North Korean threat actors behind macOS malware strains such as RustBucket and KANDYKORN have been observed "mixing and matching" different elements of the two disparate attack chains, leveraging RustBucket droppers to deliver KANDYKORN.

New macOS 'KandyKorn' malware targets cryptocurrency engineers
A new macOS malware dubbed 'KandyKorn' has been spotted in a campaign attributed to the North Korean Lazarus hacking group, targeting blockchain engineers of a cryptocurrency exchange platform. The attackers impersonate members of the cryptocurrency community on Discord channels to spread Python-based modules that trigger a multi-stage KandyKorn infection chain. Elastic Security discovered and attributed the attacks to Lazarus based on overlaps with past campaigns concerning the employed techniques, network infrastructure, code-signing certificates, and custom Lazarus detection rules.

iLeakage
We present iLeakage, a transient execution side channel targeting the Safari web browser present on Macs, iPads and iPhones. iLeakage shows that the Spectre attack is still relevant and exploitable, even after nearly 6 years of effort to mitigate it since its discovery. We show how an attacker can induce Safari to render an arbitrary webpage, subsequently recovering sensitive information present within it using speculative execution. In particular, we demonstrate how Safari allows a malicious webpage to recover secrets from popular high-value targets, such as Gmail inbox content. Finally, we demonstrate the recovery of passwords, in case these are autofilled by credential managers.
Hackers can force iOS and macOS browsers to divulge passwords and much more
iLeakage is practical and requires minimal resources. A patch isn't (yet) available.

Last Week on My Mac: How quickly can Apple release a security update?
We seldom get much insight into how long Apple takes to release an urgent update to macOS, but last week must have seen one of the quickest in recent times. By my reckoning, Apple’s engineers accomplished that in 6-10 days, across four of its operating systems, and with two distinct vulnerabilities.
