Researchers created a PoC rootkit called Curing that uses Linux’s io_uring feature to evade traditional system call monitoring. Armo researchers have demonstrated a proof-of-concept (PoC) rootkit named Curing that relies on Linux asynchronous I/O mechanism io_uring to bypass traditional system call monitoring. “Curing is a POC of a rootkit that uses io_uring to perform different tasks without using any syscalls, […]
Some patches for Linux 6.15-rc4 (updating the kernel driver for the Bcachefs file system) triggered some “straight-to-the-point wisdom” from Linus Torvalds about case-insensitive filesystems, reports Phoronix.
Bcachefs developer Kent Overstreet start…
The company has released a working rootkit called “Curing” that uses io_uring, 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 reliance on monitoring system calls, which has become the go-to method for many cybersecurity vendors. The problem? Attackers can completely sidestep these monitored calls by leaning on io_uring instead. This clever method could let bad actors quietly make network connections or tamper with files without triggering the usual alarms…

A sophisticated cyber espionage campaign leveraging the newly identified BRICKSTORM malware variants has targeted European strategic industries since at least 2022. According to NVISO’s technical analysis, these backdoors previously confined to Linux v…
Successfully demonstrated advanced cybersecurity skills by exploiting a Ghost CMS vulnerability (CVE-2023-40028) to access sensitive credentials and secure the user flag. Identified and leveraged a sudo misconfiguration with the CHECK_CONTENT variable to escalate privileges and retrieve the root flag from /root/root.txt. Thrived in this hands-on challenge, sharpening penetration testing expertise! #HackTheBox #Cybersecurity #EthicalHacking #PenetrationTesting #CTF
