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.
Health care breaches lead to legislation Highlights of the new standard include: Performing and documenting a security risk analysis of exposure Documentation of a business continuity plan (BCP) Stress test of resiliency and documentation of any planned changes to the BCP A signed statement by both the CEO and CISO of compliance * A third-party audit to certify compliance (no later than six months after enactment)
ThreatLabz has developed a tool named SmokeBuster to detect, analyze, and remediate infections. SmokeBuster supports 32-bit and 64-bit instances of SmokeLoader and versions 2017-2022. The tool is compatible with Windows 7 to Windows 11. SmokeLoader is a malware downloader that originated in 2011. The malware is primarily designed to deliver second-stage payloads, which include information stealers and ransomware. Despite a major disruption by Operation Endgame in May 2024, SmokeLoader continues to be used by numerous threat groups largely due to numerous cracked versions publicly available on the internet. The last four versions of SmokeLoader contain coding flaws that significantly impact an infected system’s performance.
In the last few days, many Tor relay operators - mainly hosting relay nodes on providers like Hetzner - began receiving abuse notices. All the abuses reported many failed SSH login attempts - part of a brute force attack - coming from their Tor relays. Tor relays normally only transport traffic between a guard and an exit node of the Tor network, and per-se should not perform any SSH connections to internet-facing hosts, let alone performing SSH brute force attacks.
