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.

New STX RAT Uses Hidden Remote Desktop and Infostealer Features to Evade Detection

A newly identified remote access trojan, STX RAT, emerged in 2026, integrating hidden remote desktop access with credential theft features. The name "STX" comes from the Start of Text magic byte x02, which it appends to communications with its command-and-control (C2) server. Initial sightings were reported in late February 2026, when it was delivered via a browser-downloaded VBScript file to a financial organization. By early March, Malwarebytes noted a campaign distributing STX RAT through compromised FileZilla installers. Researchers from eSentire’s Threat Response Unit analyzed the malware, which includes extensive anti-analysis measures and employs techniques like AMSI-ghosting. Once operational, STX RAT connects to a C2 server at 95.216.51.236, transmitting system information securely. It targets saved credentials from applications like FileZilla and includes a Hidden Virtual Network Computing (HVNC) module, allowing attackers to control a victim's machine without detection. Security teams are advised to block the C2 IP and implement detection rules to mitigate the threat.
