Security researchers have detailed a new variant of a dynamic link library (DLL) search order hijacking technique that could be used by threat actors to bypass security mechanisms and achieve execution of malicious code on systems running Microsoft Windows 10 and Windows 11.
The approach "leverages executables commonly found in the trusted WinSxS folder and exploits them via the classic DLL
As many as 34 unique vulnerable Windows Driver Model (WDM) and Windows Driver Frameworks (WDF) drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems.
"By exploiting the drivers, an attacker without privilege may erase/alter firmware, and/or elevate [operating system] privileges," Takahiro Haruyama, a
Three interrelated high-severity security flaws discovered in Kubernetes could be exploited to achieve remote code execution with elevated privileges on Windows endpoints within a cluster.
The issues, tracked as CVE-2023-3676, CVE-2023-3893, and CVE-2023-3955, carry CVSS scores of 8.8 and impact all Kubernetes environments with Windows nodes. Fixes for the vulnerabilities were released on August
A legitimate Windows tool used for creating software packages called Advanced Installer is being abused by threat actors to drop cryptocurrency-mining malware on infected machines since at least November 2021.
"The attacker uses Advanced Installer to package other legitimate software installers, such as Adobe Illustrator, Autodesk 3ds Max, and SketchUp Pro, with malicious scripts and uses
Threat actors are leveraging access to malware-infected Windows and macOS machines to deliver a proxy server application and use them as exit nodes to reroute proxy requests.
According to AT&T Alien Labs, the unnamed company that offers the proxy service operates more than 400,000 proxy exit nodes, although it's not immediately clear how many of them were co-opted by malware installed on
A previously undetected attack method called NoFilter has been found to abuse the Windows Filtering Platform (WFP) to achieve privilege escalation in the Windows operating system.
"If an attacker has the ability to execute code with admin privilege and the target is to perform LSASS Shtinkering, these privileges are not enough," Ron Ben Yizhak, a security researcher at Deep Instinct, told The
Active flaws in the PowerShell Gallery could be weaponized by threat actors to pull off supply chain attacks against the registry's users.
"These flaws make typosquatting attacks inevitable in this registry, while also making it extremely difficult for users to identify the true owner of a package," Aqua security researchers Mor Weinberger, Yakir Kadkoda, and Ilay Goldman said in a report shared
The Iranian nation-state actor known as TA453 has been linked to a new set of spear-phishing attacks that infect both Windows and macOS operating systems with malware.
"TA453 eventually used a variety of cloud hosting providers to deliver a novel infection chain that deploys the newly identified PowerShell backdoor GorjolEcho," Proofpoint said in a new report.
"When given the opportunity, TA453
