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?

FritzFrog: P2P Botnet Hops Back on the Scene
FritzFrog is a peer-to-peer botnet, which means its command and control server is not limited to a single, centralized machine, but rather can be done from every machine in its distributed network. In other words, every host running the malware process becomes part of the network, and is capable of sending, receiving, and executing the commands to control machines in the network.

Google launches AI Cyber Defense Initiative to improve security infrastructure
Today, many seasoned security professionals will tell you they’ve been fighting a constant battle against cybercriminals and state-sponsored attackers. They will also tell you that any clear-eyed assessment shows that most of the patches, preventative measures and public awareness campaigns can only succeed at mitigating yesterday’s threats — not the threats waiting in the wings. That could be changing. As the world focuses on the potential of AI — and governments and industry work on a regulatory approach to ensure AI is safe and secure — we believe that AI represents an inflection point for digital security. We’re not alone. More than 40% of people view better security as a top application for AI — and it’s a topic that will be front and center at the Munich Security Conference this weekend.

Threat Actor Leverages Compromised Account of Former Employee to Access State Government Organization | CISA
The Cybersecurity and Infrastructure Security Agency (CISA) and the Multi-State Information Sharing & Analysis Center (MS-ISAC) conducted an incident response assessment of a state government organization’s network environment after documents containing host and user information, including metadata, were posted on a dark web brokerage site. Analysis confirmed that an unidentified threat actor compromised network administrator credentials through the account of a former employee—a technique commonly leveraged by threat actors—to successfully authenticate to an internal virtual private network (VPN) access point, further navigate the victim’s on-premises environment, and execute various lightweight directory access protocol (LDAP) queries against a domain controller.[1] Analysis also focused on the victim’s Azure environment, which hosts sensitive systems and data, as well as the compromised on-premises environment. Analysis determined there were no indications the threat actor further compromised the organization by moving laterally from the on-premises environment to the Azure environment.

Gold Rush is back to APAC: Group-IB unveils first iOS trojan stealing your face
Group-IB, a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime, has uncovered a new iOS Trojan designed to steal users’ facial recognition data, identity documents, and intercept SMS. The Trojan, dubbed GoldPickaxe.iOS by Group-IB’s Threat Intelligence unit, has been attributed to a Chinese-speaking threat actor codenamed GoldFactory, responsible for developing a suite of highly sophisticated banking Trojans that also includes the earlier discovered GoldDigger and newly identified GoldDiggerPlus, GoldKefu, and GoldPickaxe for Android. To exploit the stolen biometric data, the threat actor utilizes AI face-swapping services to create deepfakes by replacing their faces with those of the victims. This method could be used by cybercriminals to gain unauthorized access to the victim’s banking account – a new fraud technique, previously unseen by Group-IB researchers. The GoldFactory Trojans target the Asia-Pacific region, specifically — Thailand and Vietnam impersonating local banks and government organizations. Group-IB’s discovery also marks a rare instance of malware targeting Apple’s mobile operating system. The detailed technical description of the Trojans, analysis of their technical capabilities, and the list of relevant indicators of compromise can be found in Group-IB’s latest blog post.
