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.
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?
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.
Triangulation: validators, post-compromise activity and modules | Securelist
In this report Kaspersky shares insights into the validation components used in Operation Triangulation, TriangleDB implant post-compromise activity, as well as details of some additional modules.
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.
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.

Is macOS’s new XProtect behavioural security preparing to go live?
Apple released its first update to its new behavioural security protection in XProtect Behaviour Service on 8 August, and again on 1 September. Here are the details.
App Management is a new macOS security feature in Ventura introduced at WWDC last year: If an app is modified by something that isn't signed by the same development team and isn't allowed by an NSUpdateSecurityPolicy, macOS will block the modification and notify the user that an app wants to manage other apps. Clicking on the notification sends people to System Settings, where they can allow an app to update and modify other apps.
Mac systems turned into proxy exit nodes by AdLoad
AdLoad malware is still infecting Mac systems years after its first appearance in 2017. AdLoad, a package bundler, has been observed delivering a wide range of payloads throughout its existence. During AT&T Alien Labs’ investigation of its most recent payload, it was discovered that the most common component dropped by AdLoad during the past year has been a proxy application turning MacOS AdLoad victims into a giant, residential proxy botnet.
