Banshee: The Stealer That "Stole Code" From MacOS XProtect
Since September, Check Point Research has been monitoring a new version of the Banshee macOS stealer, a malware linked to Russian-speaking cyber criminals targeting macOS users. This new version had been undetected for over two months until the original version of Banshee Stealer was leaked on XSS forums, which resembled similarities with the malware’s core functionality. One notable difference between the leaked source code and the version discovered by Check Point Research is the use of a string encryption algorithm. This algorithm is the same as Apple uses in its Xprotect antivirus engine for MacOS. One method of distributing Banshee Stealer involved malicious GitHub repositories, targeting Windows users with Lumma Stealer and macOS users with Banshee Stealer. Banshee operated as a ‘stealer-as-a-service’, priced at $3,000, and was advertised through Telegram and forums such as XSS and Exploit. On November 23, 2024, the malware’s source code was leaked, leading the author to shut down the operations the following day. Despite shutting down the operation, threat actors continue to distribute the new version of Banshee via phishing websites.

A New Era of macOS Sandbox Escapes: Diving into an Overlooked Attack Surface and Uncovering 10+ New Vulnerabilities – Mickey's Blogs – Exploring the world with my sword of debugger :)
A New Era of macOS Sandbox Escapes: Diving into an Overlooked Attack Surface and Uncovering 10+ New Vulnerabilities This is a blog post for my presentation at the conference POC2024. The slides are uploaded here. In the macOS system, most processes are running in a restricted sandbox environment, whether they are Apple’s own services or third-party applications. Consequently, once an attacker gains Remote Code Execution (RCE) from these processes, their capabilities are constrained. The next step for the attacker is to circumvent the sandbox to gain enhanced execution capabilities and broader file access permissions. But how to discover sandbox escape vulnerabilities? Upon reviewing the existing issues, I unearthed a significant overlooked attack surface and a novel attack technique. This led to the discovery of multiple new sandbox escape vulnerabilities: CVE-2023-27944, CVE-2023-32414, CVE-2023-32404, CVE-2023-41077, CVE-2023-42961, CVE-2024-27864, CVE-2023-42977, and more.
