VectraRAT is a previously undocumented Malware-as-a-Service platform combining a Go-based control server (VectraHub) with a native C++ Windows implant, renting from $250 monthly. The developer, operating under the handle 'Vectra' (formerly 'Nyxel'), has been active since August 2022 without prior public documentation. The platform offers hidden desktop control, keylogging, clipboard hijacking with cryptocurrency address replacement, browser credential theft, and a UAC bypass achieving elevation without user prompts. Delivered through Amadey loader and ClickFix campaigns targeting tax-themed lures, 48% of observed victims run corporate Windows editions including Windows Server 2025. Infrastructure analysis revealed exposed directories and operational panels across multiple hosting providers, with victims spanning the United States, Russia, Germany, and other nations.

Jupyter Core is a package for the core common functionality of Jupyter projects. When using Jupyter Core prior to version 5.8.0 on Windows, the shared `%PROGRAMDATA%` directory is searched for configuration files (`SYSTEM_CONFIG_PATH` and `SYSTEM_JUPYTER_PATH`), which may allow users to create configuration files affecting other users. Only shared Windows systems with multiple users and unprotected `%PROGRAMDATA%` are affected. Users should upgrade to Jupyter Core version 5.8.0 or later to receive a patch. Some other mitigations are available. As administrator, modify the permissions on the `%PROGRAMDATA%` directory so it is not writable by unauthorized users; or as administrator, create the `%PROGRAMDATA%\jupyter` directory with appropriately restrictive permissions; or as user or administrator, set the `%PROGRAMDATA%` environment variable to a directory with appropriately restrictive permissions (e.g.controlled by administrators _or_ the current user).

A misconfigured Python HTTP server on a Budapest VPS exposed the complete operational infrastructure of three distinct phishing operators. The investigation uncovered codemado, an Egyptian threat actor operating since 2018, running a full AiTM platform with custom tools including MaDoO Blaster; saroula01, deploying OAuth Device Code Flow attacks that accumulated 218 victims across 12 countries over a year; and mail-argenta, a Nigerian operator identified through infostealer logs containing his own credentials. All three actors leveraged customized Evilginx forks and AI-assisted development to build MFA-bypass infrastructure from public GitHub repositories. The campaigns targeted Microsoft 365 accounts primarily, with codemado maintaining ties to RockyBelling's "The Quarry" cybercrime ecosystem. The exposed server contained phishing configurations, credential logs, RMM installers, combolists, and Telegram session files, revealing sustained operations from at least January 2025 through May 2026.

Threat actors exploited the EtherHiding technique to store ClearFake payload routing instructions within smart contracts on the BNB Smart Chain testnet, creating an immutable command-and-control infrastructure that cannot be taken down. The attack began with injected JavaScript on a compromised Swiss website that queried blockchain contracts to deliver malicious payloads. Victims passing anti-analysis checks were fingerprinted by operating system and routed to platform-specific ClickFix social engineering overlays. The campaign simultaneously deployed SectopRAT, a .NET-based remote access trojan capable of browser session hijacking, and ACRStealer, a C++ infostealer targeting credentials and cryptocurrency wallets. An on-chain execution tracker confirmed each compromise in real time. Four smart contracts shared a single deployer wallet, with the oldest deployed nearly a year before analysis, indicating a long-running, actively maintained operation.

PdfDing is a selfhosted PDF manager, viewer and editor offering a seamless user experience on multiple devices. Prior to version 1.7.0, an access-control vulnerability allows unauthenticated users to retrieve password-protected shared PDFs by directly calling the file-serving endpoint without completing the password verification flow. This results in unauthorized access to confidential documents that users expected to be protected by a shared-link password. This issue has been patched in version 1.7.0.
