Jan 10, 2024 Vulnerability / Windows Security
Microsoft has addressed a total of  48 security flaws  spanning its software as part of its Patch Tuesday updates for January 2024. Of the 48 bugs, two are rated Critical and 46 are rated Important in severity. There is no evidence that any of the issues are publicly known or under active attack at the time of release, making it the second consecutive Patch Tuesday with no zero-days. The fixes are in addition to  nine security vulnerabilities  that have been resolved in the Chromium-based Edge browser since the release of  December 2023 Patch Tuesday  updates. This also includes a fix for a zero-day ( CVE-2023-7024 , CVSS score: 8.8) that Google said has been actively exploited in the wild. The most critical among the flaws patched this month are as follows - CVE-2024-20674  (CVSS score: 9.0) - Windows Kerberos Security Feature Bypass Vulnerability CVE-2024-20700  (CVSS score: 7.5) - Windows Hyper-V Remote Code Execution Vulnerability "The authentication feature could be bypas

New Variant of DLL Search Order Hijacking Bypasses Windows 10 and 11 Protections

New Variant of DLL Search Order Hijacking Bypasses Windows 10 and 11 Protections
Jan 01, 2024 Windows Security / Vulnerability
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 search order hijacking technique," cybersecurity firm Security Joes  said  in a new report exclusively shared with The Hacker News. In doing so, it allows adversaries to eliminate the need for elevated privileges when attempting to run nefarious code on a compromised machine as well as introduce potentially vulnerable binaries into the attack chain, as  observed   in the   past . DLL search order hijacking , as the name implies, involves  gaming the search order  used to load DLLs in order to execute malicious payloads for purposes of defense evasion, persistence, and privilege escal

Researchers Find 34 Windows Drivers Vulnerable to Full Device Takeover

Researchers Find 34 Windows Drivers Vulnerable to Full Device Takeover
Nov 02, 2023 Endpoint Security / Malware
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 senior threat researcher at VMware Carbon Black,  said . The  research  expands on previous studies, such as  ScrewedDrivers  and  POPKORN  that utilized  symbolic execution  for automating the discovery of vulnerable drivers. It specifically focuses on drivers that contain firmware access through port I/O and memory-mapped I/O. The names of some of the vulnerable drivers include AODDriver.sys, ComputerZ.sys, dellbios.sys, GEDevDrv.sys, GtcKmdfBs.sys, IoAccess.sys, kerneld.amd64, ngiodriver.sys, nvoclock.sys, PDFWKRNL.sys ( CVE-2023-20598 ), RadHwMgr.sys, rtif.sys, rtport.sys, s

Cybercriminals Weaponizing Legitimate Advanced Installer Tool in Crypto-Mining Attacks

Cybercriminals Weaponizing Legitimate Advanced Installer Tool in Crypto-Mining Attacks
Sep 09, 2023 Malware / Hacking
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 Advanced Installer's Custom Actions feature to make the software installers execute the malicious scripts," Cisco Talos researcher Chetan Raghuprasad  said  in a technical report. The nature of the applications trojanized indicates that the victims likely span architecture, engineering, construction, manufacturing, and entertainment sectors. The software installers predominantly use the French language, a sign that French-speaking users are being singled out. This  campaign  is strategic in that these industries rely on computers with high Graphics Processing Unit (GPU) power for t

This Malware Turned Thousands of Hacked Windows and macOS PCs into Proxy Servers

This Malware Turned Thousands of Hacked Windows and macOS PCs into Proxy Servers
Aug 21, 2023 Malware / Privacy
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 infected machines without user knowledge and interaction. "Although the proxy website claims that its exit nodes come only from users who have been informed and agreed to the use of their device," the cybersecurity company  said  it found evidence where "malware writers are installing the proxy silently in infected systems." Multiple malware families have been observed delivering the proxy to users searching for cracked software and games. The proxy software, written in the Go programming language, is capable of targeting both Windows and macOS, with the former capable o

NoFilter Attack: Sneaky Privilege Escalation Method Bypasses Windows Security

NoFilter Attack: Sneaky Privilege Escalation Method Bypasses Windows Security
Aug 17, 2023 Endpoint Security / Vulnerability
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 Hacker News. "Running as "NT AUTHORITY\SYSTEM" is required. The techniques described in this research can escalate from admin to SYSTEM." The  findings  were presented at the DEF CON security conference over the weekend. The starting point of the  research  is an in-house tool called RPC Mapper the cybersecurity company used to map remote procedure call ( RPC ) methods, specifically those that invoke  WinAPI , leading to the discovery of a method named "BfeRpcOpenToken," which is part of WFP. WFP is a  set of API and system services  that's

Experts Uncover Weaknesses in PowerShell Gallery Enabling Supply Chain Attacks

Experts Uncover Weaknesses in PowerShell Gallery Enabling Supply Chain Attacks
Aug 16, 2023 Windows Security / Supply Chain
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 with The Hacker News. Maintained by Microsoft,  PowerShell Gallery  is a  central repository  for sharing and acquiring PowerShell code, including PowerShell modules, scripts, and Desired State Configuration (DSC) resources. The registry boasts of 11,829 unique packages and 244,615 packages in total. The issues identified by the cloud security firm have to do with the service's lax policy surrounding package names, lacking protections against typosquatting attacks, as a result enabling attackers to upload malicious PowerShell modules that appear genuine to unsuspecting us

Iranian Hackers' Sophisticated Malware Targets Windows and macOS Users

Iranian Hackers' Sophisticated Malware Targets Windows and macOS Users
Jul 06, 2023 Endpoint Security / Malware
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 ported its malware and attempted to launch an Apple flavored infection chain dubbed NokNok. TA453 also employed  multi-persona impersonation  in its unending espionage quest." TA453, also known by the names APT35, Charming Kitten, Mint Sandstorm, and Yellow Garuda, is a threat group linked to Iran's Islamic Revolutionary Guard Corps (IRGC) that has been active since at least 2011. Most recently, Volexity highlighted the adversary's use of an updated version of a Powershell implant called  CharmPower  (aka GhostEcho or POWERSTAR). In the attack sequence discove
