This guide shows how to use MQTT to integrate lithium‑ion battery voltage, state‑of‑charge and health data from an ESP8266 into Home Assistant and a WeChat mini‑program, providing configuration examples, JSON payloads, and links to the fully open‑source repositories.
A technical review reveals that Telegram’s MTProto protocol exposes a permanent 64‑bit device identifier (auth_key_id) in clear text, enabling passive observers—including ISPs, mobile carriers, and state surveillance—to track users across app restarts, IP changes, VPNs, and even Tor, rendering secret chats and PFS ineffective.
The article examines recent high‑severity NGINX CVEs, revisits historic over‑hyped bugs, explains why CVSS scores alone mislead, outlines the typical hype lifecycle, and proposes a risk‑based assessment workflow for security teams to avoid chasing phantom threats.
A newly disclosed nginx‑poolslip 0‑day RCE affecting NGINX 1.31.0 targets the internal memory‑pool, requires a rare non‑default configuration, and while no public PoC exists, analysis of 4,000 real configurations found none exploitable, prompting specific mitigation steps.
KAIDO RAT v3.0, a .NET 9‑based modular malware suite with over 60 plugins, targets Brazil's PIX payment system, injects malicious QR codes, locks user devices, harvests AI platform credentials, and employs advanced evasion techniques, while the article also offers detailed defense recommendations.
After TeamPCP posted a $50,000 offer for 4,000 private GitHub repositories, the data was transferred to LAPSUS$, the price doubled to $95,000, and the breach highlighted a supply‑chain attack chain that now threatens infrastructure credentials and prompts urgent self‑audit steps.
The article dissects the May 2026 leak of the ransomware‑as‑a‑service group The Gentlemen, detailing its rapid rise, profit‑sharing model, edge‑device entry points, AI‑assisted tool development, supply‑chain attacks, internal breach, and concrete blue‑team mitigation recommendations.
Security researchers dissected vm2, the popular Node.js sandbox library, and disclosed twelve vulnerabilities—including three CVSS 10.0 flaws that allow unchecked require, WebAssembly JSPI escape, and deny‑list bypass—prompting immediate upgrades and mitigation steps for all users.
This guide walks individual developers through installing Gitea—using Docker‑compose or binary packages—configuring a systemd service for automatic startup, accessing the web UI to create a repository, and linking it with IDEs to push code, providing a lightweight, self‑hosted Git platform for secure project management.
By sending a legitimate JSON payload that injects MongoDB operators such as $gt or $ne into the password field, attackers can trick a Node.js‑Express login endpoint into authenticating any user, illustrating how NoSQL injection bypasses authentication and how to detect and mitigate it.
