Recently, researchers have discovered a brand new Linux rootkit—Curing—that can successfully bypass existing security tools through the io_uring interface in the Linux kernel, rendering it invisible in the system and even evading detection by modern enterprise-level security software. The io_uring interface was introduced in the Linux 5.1 version to enhance I/O operation performance, aiming to … Read more
Compiled by | Zheng LiyuanProduced by | CSDN (ID: CSDNnews) In the open-source community, Linus Torvalds’ outbursts often trigger a wave of “mini-earthquakes”. Recently, the father of Linux has once again fired back — this time targeting a long-standing issue in file system development: case insensitivity (i.e., not distinguishing between uppercase and lowercase characters). He … Read more
In Linux system administration, the Principle of Least Privilege (PoLP) is one of the core principles of secure operations. Directly using the <span>root</span> user for operations carries high risks; it is recommended to create an administrator user with <span>sudo</span> privileges (such as <span>admin</span>) to reduce the impact of accidental operations and security threats. This article … Read more
Recently, cybersecurity researchers demonstrated a proof-of-concept (PoC) Rootkit named “Curing” that utilizes the Linux asynchronous I/O mechanism io_uring to bypass traditional system call monitoring. 01 Significant Blind Spots in Security Tools ARMO stated that this leads to “significant blind spots in Linux runtime security tools.” In a report shared with The Hacker News, the company … Read more
