In a sign that cybersecurity researchers continue to be under the radar of malicious actors, a proof-of-concept (PoC) has been discovered on GitHub, concealing a backdoor with a “crafty” persistence method. “In this instance, the PoC is a wolf in sheep’s clothing, harboring malicious intent under the guise of a harmless learning tool,” Uptycs researchers […]
Details have emerged about a newly identified security flaw in the Linux kernel that could allow a user to gain elevated privileges on a target host. Dubbed StackRot (CVE-2023-3269, CVSS score: 7.8), the flaw impacts Linux versions 6.1 through 6.4. There is no evidence that the shortcoming has been exploited in the wild to date. […]
An unknown Chinese state-sponsored hacking group has been linked to a novel piece of malware aimed at Linux servers. French cybersecurity firm ExaTrack, which found three samples of the previously documented malicious software that date back to early 2022, dubbed it Mélofée. One of the artifacts is designed to drop a kernel-mode rootkit that’s based […]
A new, multi-functional Go-based malware dubbed Chaos has been rapidly growing in volume in recent months to ensnare a wide range of Windows, Linux, small office/home office (SOHO) routers, and enterprise servers into its botnet. “Chaos functionality includes the ability to enumerate the host environment, run remote shell commands, load additional modules, automatically propagate through […]
Cybersecurity researchers have taken the wraps off a new and entirely undetected Linux threat dubbed OrBit, signally a growing trend of malware attacks geared towards the popular operating system. The malware gets its name from one of the filenames that’s utilized to temporarily store the output of executed commands (“/tmp/.orbit”), according to cybersecurity firm Intezer. […]
Linux distributions are in the process of issuing patches to address a newly disclosed security vulnerability in the kernel that could allow an attacker to overwrite arbitrary data into any read-only files and allow for a complete takeover of affected systems. Dubbed “Dirty Pipe” (CVE-2022-0847, CVSS score: 7.8) by IONOS software developer Max Kellermann, the […]
Cybersecurity researchers have detailed a new campaign that likely targets entities in Southeast Asia with a previously unrecognized Linux malware that’s engineered to enable remote access to its operators, in addition to amassing credentials and function as a proxy server. The malware family, dubbed “FontOnLake” by Slovak cybersecurity firm ESET, is said to feature “well-designed […]
The cross-site scripting (XSS) susceptibility plus various supply chain operations greatly impact on the Linux marketplaces, which are located on the Pling platform. This is the outcome of a study carried out by the German cyber security practice Positive Security. Pling Platform Pling is vital as it enables the establishment of free and open-source software […]
Cybersecurity researchers have disclosed a new backdoor program capable of stealing user login credentials, device information and executing arbitrary commands on Linux systems. The malware dropper has been dubbed “Facefish” by Qihoo 360 NETLAB team owing its capabilities to deliver different rootkits at different times and the use of Blowfish cipher to encrypt communications to […]
A previously undocumented Linux malware with backdoor capabilities has managed to stay under the radar for about three years, allowing the threat actor behind the operation to harvest and exfiltrate sensitive information from infected systems. Dubbed “RotaJakiro” by researchers from Qihoo 360 NETLAB, the backdoor targets Linux X64 machines, and is so named after the […]
Movies and TV shows pop up in our minds when we say the word Netflix. But it turns out the company wants to do a lot more than just entertain its users. Netflix researchers found four critical vulnerabilities that affect different versions of Linux and FreeBSD kernels deployed in systems worldwide. As explained in the […]
Short Bytes: Researchers have found a critical flaw that affects all Linux kernel version 3.6 and beyond. If left unnoticed, this flaw allows a range of harmful blind off-path TCP attacks that can compromise the security of a Linux user with a success rate of 90%. The researchers have proposed certain changes and implementation of a […]
Linux is considered as one of the most secure operating systems — However, there’s a trojan attacking specifically those on Linux. Linux users could be in danger of getting attacked by a powerful and picky Trojan as a Russian anti-virus maker, Dr.Web, has found a Trojan which is aimed towards Linux users known as Rekoobe. […]
