New Linux Rootkit

Interesting: The company has released a working rootkit called "Curing" that uses iouring, a feature built into the Linux kernel, to stealthily perform malicious activities without being caught by many of the detection solutions currently on the market. At the heart of the issue is the heavy...

Linux io_uring PoC Rootkit Bypasses System Call-Based Threat Detection Tools

Cybersecurity researchers have demonstrated a proof-of-concept PoC rootkit dubbed Curing that leverages a Linux asynchronous I/O mechanism called iouring to bypass traditional system call monitoring. This causes a "major blind spot in Linux runtime security tools," ARMO said. "This mechanism allo...
