Stop installing these 4 apps—Windows does it all now

Windows has evolved to integrate functionalities that were once reliant on third-party applications, such as native support for ZIP files introduced in Windows ME in 2000, and the ability to open and create RAR, TAR, and 7z formats directly from File Explorer. Features like Storage Sense have replaced the need for tools like CCleaner by allowing users to manage temporary files more easily, and the effectiveness of Windows Defender has reduced the necessity for third-party antivirus solutions. Additionally, modern Windows can mount ISO files directly, eliminating the need for applications like Daemon Tools. The trend of operating systems adopting features from third-party applications, known as "Sherlocking," reflects a response to user demands while still allowing for optional third-party solutions.

Windows might be hiding some of your PC’s storage by default – here’s how to reclaim it

Windows' Reserved Storage feature allocates 5GB to 10GB of SSD space for system files, updates, and temporary data, impacting the usable storage capacity. Users can clear cache and utilize Windows PC Manager to free up space. To disable Reserved Storage, navigate to Settings > System > Storage > System & Reserved, and use the command: DISM.exe /Online /Set-ReservedStorageState /State:Disabled. For SSDs of 512GB or more, the impact is minimal, but for smaller SSDs, reclaiming this space can be beneficial. It is recommended to re-enable Reserved Storage before system updates using the command: DISM.exe /Online /Set-ReservedStorageState /State:Enabled. A minimum SSD capacity of 512GB is advised for a seamless experience, and upgrading or using external storage solutions is suggested for enhanced capacity. Caution is advised with budget SSDs due to potential reliability issues.

Dragon Breath Uses RONINGLOADER to Disable Security Tools and Deploy Gh0st RAT

The threat actor Dragon Breath, also known as APT-Q-27 and Golden Eye, has been observed using a multi-stage loader called RONINGLOADER to deploy a modified variant of the remote access trojan Gh0st RAT, primarily targeting Chinese-speaking users. The campaign employs trojanized NSIS installers disguised as legitimate applications, such as Google Chrome and Microsoft Teams. The infection chain utilizes various evasion techniques, including a legitimately signed driver, custom Windows Defender Application Control policies, and manipulation of the Microsoft Defender binary. RONINGLOADER's attack chain involves delivering a DLL and an encrypted file labeled "tp.png," which contains shellcode. It attempts to neutralize security products by terminating processes associated with popular antivirus solutions in the region. Specific actions are taken against Qihoo 360 Total Security, including blocking network communication, injecting shellcode into the Volume Shadow Copy service, and restoring firewall settings. For other security processes, RONINGLOADER directly writes a driver to disk to perform process termination. The malware aims to inject a rogue DLL into "regsvr32.exe" to conceal its activities and launch a next-stage payload into high-privilege system processes. The final payload is a modified version of Gh0st RAT, capable of communicating with a remote server, configuring Windows Registry keys, clearing Windows Event logs, and capturing keystrokes and clipboard contents. Additionally, two interconnected malware campaigns identified by Palo Alto Networks Unit 42 employed brand impersonation to deliver Gh0st RAT to Chinese-speaking users. The first campaign, Campaign Trio, occurred between February and March 2025, while the second, Campaign Chorus, detected in May 2025, impersonated over 40 applications. Both campaigns utilized complex infection chains and trojanized installers hosted on domains that circumvented network filters. The second campaign also involved an embedded Visual Basic Script for launching the final payload through DLL side-loading.

RONINGLOADER Weaponizes Signed Drivers to Disable Defender and Evade EDR Tools

A new malware called RONINGLOADER specifically targets Chinese users and can disable security tools. It operates as a multi-stage loader that spreads a modified version of gh0st RAT and bypasses antivirus protections. RONINGLOADER infiltrates systems through fake software installers that mimic legitimate applications like Google Chrome and Microsoft Teams. Once inside, it disables Windows Defender and Chinese security solutions such as Qihoo 360 Total Security and Huorong. The malware uses a signed driver that appears legitimate to Windows but is designed to terminate security processes. If one method of disabling security fails, RONINGLOADER has multiple fallback strategies. The Dragon Breath APT group is behind this campaign, having refined their techniques based on previous operations. The infection begins with a trojanized NSIS installer that drops components onto the victim's system. One installer deploys genuine software, while the other initiates the attack chain. RONINGLOADER creates a directory at C:Program FilesSnieoatwtregoable and deposits two files: Snieoatwtregoable.dll and an encrypted file named tp.png. The DLL decrypts tp.png using XOR encryption and a rotation operation, then loads new system libraries to eliminate security hooks. It elevates privileges using the runas command and scans for active security software, specifically targeting Microsoft Defender, Kingsoft Internet Security, Tencent PC Manager, and Qihoo 360 Total Security. To terminate these processes, it uses a signed driver named ollama.sys, which is digitally signed by Kunming Wuqi E-commerce Co., Ltd. This driver can terminate processes using kernel-level APIs that standard security tools cannot intercept. Additionally, RONINGLOADER blocks network connections for Qihoo 360 before injecting code into the Volume Shadow Copy service process, utilizing Windows thread pools with file write triggers to evade detection.
