Hackers Use Fake Windows Update Installers to Deliver OnyxC2 Credential Stealer

OnyxC2 is a sophisticated credential stealer available for a subscription fee of 0 per month, distributed through disguised lures such as fake Windows updates and legitimate software installers. It functions as a commercial product with features like an automated payload builder, tiered licensing, and a centralized web dashboard. The malware boasts a 99% detection-evasion rate, successfully evading major antivirus solutions during tests. It is developed in C++, utilizing direct system calls and mutating with each build to avoid detection. OnyxC2 collects data from around 210 applications, targeting 45 web browsers, password managers, cryptocurrency wallets, and FTP clients. The malware is delivered using DLL sideloading, where a password-protected archive contains a legitimate application and a malicious DLL. The attacker's DLL is disguised by inflating its size and is loaded by a trusted binary. The malicious code remains encrypted on disk and decrypts in memory to evade analysis. OnyxC2 communicates with a Cloudflare-fronted command-and-control server to manage infected hosts and execute commands like hardware registration and cookie uploads. The threat extends to business environments, targeting FTP and email clients, with stolen session cookies allowing ongoing access to corporate infrastructure. Implementing anti-data exfiltration controls is recommended as a mitigation strategy.

Microsoft fixes Windows update failures linked to WUSA installer

Microsoft resolved an issue affecting the installation of Windows updates released since May 2025, which primarily impacted users using the Windows Update Standalone Installer (WUSA) from a network share, especially in enterprise environments. The problem was significant for devices running Windows 11 24H2/25H2 and Windows Server 2025, but did not occur when handling a single .msu file or when files were stored locally. In August 2025, Microsoft acknowledged that updates installed using WUSA might fail with error ERRORBADPATHNAME when multiple .msu files were involved. A Known Issue Rollback Group Policy was implemented in September 2025 to mitigate the impact on home and non-managed business devices. The issue was ultimately resolved with cumulative updates released in June 2026 for Windows 11 (KB5079391) and Windows Server 2025 (KB5094125). Microsoft provided a workaround for users experiencing difficulties with prior updates by suggesting they save .msu files locally for installation. Users were also advised to wait at least 15 minutes after installing an .msu file via WUSA before checking the Update History page. Additionally, Microsoft had previously addressed another issue in April 2025 that affected enterprise customers installing security updates via WSUS, which recurred in the August 2025 updates. Microsoft warned customers about potential issues with installing the latest monthly updates on devices upgraded to Windows 11 24H2 or 25H2.

Fake ChatGPT download site infects Windows and Mac users with malware

A counterfeit website, openew[.]app, is impersonating OpenAI's official ChatGPT download page and distributing malware. Windows users who download from this site receive a credential-stealing malware loader, while macOS users are infected with Odyssey Stealer, a variant associated with cryptocurrency theft. The fake site mimics the legitimate ChatGPT interface and uses HTTPS to appear trustworthy. The Windows malware, Chat_GPT.exe, creates a back channel to an attacker-controlled server, while the macOS malware captures sensitive data and attempts to replace legitimate cryptocurrency wallet applications with compromised versions. Users who download from official sources remain safe, but those who click on ads or unfamiliar links risk compromising their online accounts and sensitive information. Malwarebytes offers protection against this malware. Indicators of compromise include specific file hashes and network indicators associated with the malicious site.

What Is OneLaunch.exe? Pros, Cons, and How to Remove It

OneLaunch is a software application that creates a personalized dock and desktop environment on Windows computers, often pre-installed or bundled with other software. It has received mixed reviews, with concerns about system slowdowns and its legitimacy. OneLaunch.exe is a background process supporting the OneLaunch application, which provides quick access to applications and updates but can consume system resources. The OneLaunch browser, installed alongside the main application, can alter browser settings and redirect searches, potentially leading to unwanted advertisements. While OneLaunch is not classified as traditional malware, it is often categorized as a Potentially Unwanted Program (PUP) due to its bundled installation and ability to modify system settings. It can monitor browsing habits and share data with third-party advertisers. Users report intrusive behavior, such as altering default browser settings, and it can negatively impact system performance. To remove OneLaunch, users should end the running process, uninstall the application, delete leftover folders, remove startup entries, and reset browser settings. OneLaunch may reappear due to accidental reinstallations, active browser extensions, lingering scheduled tasks, or hidden companion programs. Preventative measures include downloading from official sources, reading installation screens carefully, keeping systems updated, and performing regular system checks.

Use Windows Sandbox and containers to test untrusted apps safely

Windows 11 features Smart App Control to block untrusted applications and includes Windows Sandbox, a lightweight virtual machine that provides an isolated desktop environment for safely executing applications. Windows Sandbox uses container technology and hypervisor-based virtualization to mitigate risks associated with untrusted software. It ensures that each session starts fresh, with no data persisting after closing, and applications installed on the host system are not accessible within the Sandbox. Starting with Windows 11 version 22H2, data can persist through restarts initiated within the Sandbox. Windows Sandbox is included in supported Windows editions such as Pro, Enterprise, and Education, and offers quick launch times, a lower memory footprint, and a secure environment for testing untrusted software. Setting up Windows Sandbox involves searching for it in the Start menu, running it as an administrator, and transferring executable files for installation within the Sandbox.
