Targets all macOS versions, crashes the kernel to prove the existence of a memory corruption. The exploit accompanying this write-up consists of three parts: I was originally looking through its source in the hope of finding a low-hanging fruit that would let me compromise an iOS kernel, but what I didn’t know then is that some parts of IOHIDFamily exist only on macOS - specifically IOHIDSystem, which contains the vulnerability discussed herein. IOHIDFamily has been notorious in the past for the many race conditions it contained, which ultimately led to large parts of it being rewritten to make use of command gates, as well as large parts being locked down by means of entitlements. This is the tale of a macOS-only vulnerability in IOHIDFamily that yields kernel r/w and can be exploited by any unprivileged user.

The latest iteration uses new techniques to help prevent detection by security tools, the researchers report.

OSAMiner, which has been active since 2015, has been distributed through hacked video games, such as League of Legends, as well as compromised versions of software packages, including Microsoft Office for macOS, Sentinel Labs says. The malware now uses multiple versions of AppleScript - a scripting language used in macOS devices - to support obfuscation. OSAMiner's operators released the latest version of the cryptominer in 2020, but researchers only recently discovered the enhancements, according to the researchers' report.

"In late 2020, we discovered that the malware authors, presumably building on their earlier success in evading full analysis, had continued to develop and evolve their techniques," says Phil Stokes, a threat researcher at Sentinel Labs. "Recent versions of macOS.OSAMiner add greater complexity by embedding one run-only AppleScript inside another, further complicating the already difficult process of analysis."

OSAMiner uses run-only AppleScripts to make reverse-engineering of its code difficult, the researchers say. To decompile the malicious malware scripts, Sentinel Labs researchers had to use a relatively lesser-known AppleScript-disassembler project and another custom tool developed by the security firm.
