LofyStealer Uses Node.js Loader Against Minecraft Gamers

Cybersecurity threat hunters have discovered an active infostealer campaign targeting the gaming community, involving malware called LofyStealer (or GrabBot) that disguises itself as a Minecraft hack named “Slinky.” The attackers use the official game icon to trick young gamers into executing the malware. The Brazilian cybercrime group LofyGang has enhanced its technical capabilities, utilizing a sophisticated two-stage modular architecture. The initial stage features a 53.5 MB loader file named load.exe, which is a Node.js runtime environment that obscures malicious signatures. The loader connects to the attacker’s server and decrypts a 1.4 MB C++ payload, chromelevator.exe, which targets eight web browsers to extract sensitive information like cookies and passwords. The stolen data is compressed, encrypted, and sent to the attacker’s server. LofyGang has evolved into a Malware-as-a-Service platform, offering a web panel for operators to monitor victims and generate custom executables. The campaign highlights the increasing threats to the gaming community, with advanced evasion techniques being employed by cybercriminals. Security professionals are advised to monitor network traffic and conduct audits for suspicious activities.

Windows AI Recall is pushing data destruction upstream

The introduction of Copilot+ PCs has created new complexities in IT asset disposition (ITAD), as these devices may contain a comprehensive, time-stamped archive of user activity, which was not present on corporate laptops two years ago. Microsoft's Recall feature captures user activity screenshots and stores them securely, but recent research by Alexander Hagenah suggests that the safeguards may be ineffective, as his tool can extract sensitive data without breaking encryption. Microsoft defends the security of Recall, stating that observed access patterns align with intended protections. This situation presents challenges for ITAD operators, as pre-collection now constitutes a data-destruction event, requiring devices to be powered down or purged before leaving the client’s environment. Certificates of sanitization must evolve to address the specific destruction of Recall snapshot stores, and conversations with clients should differentiate between managed and unmanaged fleets regarding Recall settings. The presence of Recall shifts some data-destruction responsibilities upstream to clients, complicating traditional ITAD value propositions.

Inside the Architecture of an MCP Server for PostgreSQL

The Model Context Protocol (MCP) serves as a standard interface between large language models (LLMs) and external systems like PostgreSQL, emphasizing the importance of control over mere connectivity. An MCP server must act as a mediation and policy layer, enforcing security boundaries and ensuring that connections default to read-only. It should validate AI-generated SQL as untrusted input, encapsulate queries within transactions, and apply execution-time controls. The server must separate query generation from execution approval to manage operational costs and enforce guardrails on query types, such as limiting the number of rows returned. Token efficiency is crucial, with design considerations for compact data representation and schema introspection. In production, connection management is vital to prevent data leakage among multiple AI agents, and observability through logging executed queries and metadata is necessary for debugging and compliance. Long-running sessions require support for paginated responses to manage context effectively. Overall, the MCP server must integrate security, query safety, token efficiency, and observability into its design from the outset.

Minecraft Players Targeted by LofyStealer Using Node.js Loader and In-Memory Browser Injection

A new infostealer malware called LofyStealer is targeting the gaming community, particularly Minecraft players, by disguising itself as a cheat tool named “Slinky.” It employs a two-stage attack to extract sensitive information from eight major web browsers, including Chrome and Firefox, while evading detection by security software. The malware siphons off cookies, saved passwords, payment card information, and session tokens. Researchers at Zenox.ai identified LofyStealer, linking it to the Brazilian cybercrime group LofyGang, which has been active since October 2022. The malware uses social engineering tactics to appear legitimate and operates as a Malware-as-a-Service platform, offering both Free and Premium tiers to buyers. Its technical sophistication is evident in its method of in-memory browser injection, which allows it to bypass security defenses. The stolen data is compressed and sent to a command-and-control server. Users are advised to avoid downloading unofficial game mods and enable multi-factor authentication to reduce the risk of credential theft. Security teams should monitor for specific behavioral indicators related to the malware's operations.

Signal isn’t broken — so how are hackers targeting the world’s ‘most secure’ chat app?

On April 26, hackers allegedly linked to Russian groups targeted the Signal messaging app with phishing attacks aimed at senior politicians. These attacks did not compromise Signal's end-to-end encryption; rather, they deceived users into providing access to their accounts through fake messages. Signal is operated by the non-profit Signal Foundation, founded in 2012 by Moxie Marlinspike with funding from Brian Acton, a co-founder of WhatsApp. Signal distinguishes itself by rendering metadata invisible to its operators, unlike WhatsApp, which shares user data with its parent company. Signal's president, Meredith Whittaker, advocates for data privacy.

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.

Trojanized Android App Fuels New Wave of NFC Fraud

A new variant of the NGate malware family has emerged, using a trojanized Android application to capture payment card data and personal identification numbers (PINs). This modified version of HandyPay, a legitimate NFC relay app, has been distributed since November 2025, primarily targeting users in Brazil. The malware intercepts NFC payment card data and allows fraudulent transactions. Two distinct malware samples have been observed, delivered through phishing infrastructure that impersonates a Brazilian lottery site and a Google Play listing for a card protection tool. The trojanized app captures NFC data, requests the victim's card PIN, and transmits this information to attacker-controlled infrastructure. It requires minimal permissions, leveraging its role as the default payment application to evade detection. Evidence suggests that generative AI tools may have been used in its development, indicated by emoji markers in debug logs. ESET has reported its findings to Google, and Google Play Protect can detect known versions of the malware. The developer of HandyPay is investigating the misuse of its application.
