Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, featuring a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent responds to customer queries, calculates service pricing, manages service acceptance, suggests time slots, and confirms appointment details. It operates in two modes: in-memory for rapid testing and Postgres for persistent storage. Testing can be done locally using Docker, which simulates a Postgres environment, or with a hosted Postgres instance. The project includes a docker-compose.yml file to initiate a PostgreSQL 16 container, allowing the application to connect to the database. Data persistence is ensured through Docker volumes, and the application can be run with specific commands after setting up the environment variables. The system has been tested successfully, demonstrating its ability to manage bookings and maintain data integrity across sessions. Future enhancements are planned to improve the booking workflow and integrate additional communication channels.

Microsoft blames RGB peripherals for crashing Windows 11 — RGB software is causing blue screens, crashes, and game freezes

Windows 11 users are experiencing system instabilities, including game freezes, crashes, and blue screen errors, following the KB5121003 update. The issue is linked to RGB software that conflicts with essential system components. Affected online multiplayer games, such as Arc Raiders and Marvel Tokon: Fighting Souls, are particularly impacted, with players encountering "EXCEPTIONACCESSVIOLATION" errors. The problematic driver, often named "inpoutx64," is associated with RGB lighting control and operates in kernel space, leading to vulnerabilities that anti-cheat mechanisms aim to mitigate. When the driver is blocked, it causes critical errors resulting in system crashes. Microsoft has suggested temporary workarounds using compatible programs like SignalRGB or OpenRGB to manage RGB devices without triggering anti-cheat alerts. Users are encouraged to report issues through the Feedback Hub for resolution prioritization.

Hackers abuse FTP server banners to deliver new Windows malware

Threat actors are exploiting FTP banners to conceal commands for deploying two undocumented remote access trojans (RATs), E4del and PINHOLE. This method was first observed by MalwareHunterTeam in July 2026, using shortcut files (.LNK) and FTP server banners as dead-drop resolvers to retrieve malicious commands. SOCRadar confirmed that this technique has been weaponized since early July 2026 and remains active, with new infrastructure identified as recently as August 2026. The attacks typically start with a ZIP archive leading to an LNK-based infection chain, likely initiated through phishing tactics. E4del is a Node.js-based RAT disguised within a digitally signed Electron application mimicking Discord, capable of executing commands, capturing screenshots, streaming desktops, and downloading additional payloads. It also includes a module for privilege escalation. PINHOLE retrieves its command and control configuration from Pinterest and SurveyMonkey, designed to leave a minimal footprint and employing shellcode fluctuation. It supports 14 commands, including file management and credential theft, but had only recorded 11 execution events at the time of analysis. SOCRadar notes that while using FTP banners is a novel approach, it is less stealthy than traditional web-based dead-drop resolvers. They provide indicators of compromise to help identify malicious infrastructure and infected machines.

Mustang Panda Adds Signed Windows Rootkit to CoolClient Backdoor for Stealth

The threat actor known as HoneyMyte, also referred to as Mustang Panda, has been deploying an upgraded version of the CoolClient backdoor, which includes a signed Windows kernel-mode rootkit. This rootkit enhances the malware's ability to conceal malicious processes, files, registry objects, and command-and-control (C2) network information. Victims have been identified in Myanmar, Mongolia, Pakistan, and Russia, with confirmed targets including government entities. The CoolClient backdoor is deployed as a secondary access layer following an initial PlugX infection. The kernel component activates when CoolClient gains full access to the Service Control Manager (SCM) and the SeTcbPrivilege privilege. If these conditions are not met, the malware bypasses driver deployment and advances to the final-stage implant. Kaspersky has provided indicators of compromise (IoCs), including file hashes, paths, and C2 domains. In a campaign targeting Myanmar, HoneyMyte used PlugX as the initial implant to deploy CoolClient, which involved creating Microsoft Defender exclusions and renaming a legitimate executable for DLL sideloading. Persistence is achieved through a scheduled task that executes the binary with SYSTEM privileges at startup. Execution begins when a legitimate application loads a malicious DLL, which then manages persistence, registry modifications, UAC bypass, process injection, driver deployment, and C2 communications. When privileges are granted, the malware extracts a kernel driver, writes it to disk, and establishes a driver service. The driver is digitally signed with a certificate from Nanjing Ranyi Technology Co., Ltd. The driver receives configuration data from the CoolClient user-mode component and utilizes specific IOCTL requests to register trusted processes and protect filesystem and registry paths. The rootkit can limit access rights to protected processes, hide processes by unlinking them from the active process list, and deny access to protected files and directories. It also filters C2 IPv4 addresses from network information. The driver incorporates 33 IOCTL handlers, but only three were observed in use during standard execution. Kaspersky shared several file hashes related to the malware, including those for the kernel driver and malicious DLLs. This follows earlier disclosures regarding a newer CoolClient variant and a different HoneyMyte kernel-mode rootkit documented in December 2025.

APT group HoneyMyte upgrades CoolClient: the backdoor gets a kernel-level Windows rootkit

CoolClient is a sophisticated backdoor family linked to the HoneyMyte APT group, actively used in cyber-espionage campaigns targeting organizations in Asia and Russia since its initial disclosure in 2022. It has capabilities such as keylogging, clipboard theft, credential harvesting, and system reconnaissance. Investigations in 2023 revealed enhancements, including clipboard theft and HTTP traffic interception. By late 2025 and into 2026, a variant was noted that could deploy a signed kernel-mode driver as a Windows service, improving its stealth and operational capabilities. In a recent campaign targeting Myanmar, the HoneyMyte group used PlugX to deploy CoolClient components. They configured Microsoft Defender to exclude a fake Windows Defender installation directory and a renamed executable, defender.exe, to avoid detection. Persistence was achieved through a scheduled task that executed defender.exe with SYSTEM privileges at startup, which sideloaded the malicious libngs.dll to initiate the CoolClient execution chain. The latest CoolClient variant has a multi-stage execution chain, including: - defender.exe / Sang.exe: Exploited legitimate application for DLL sideloading. - libsrapc.dll: Benign dependency for the Sangfor application. - libngs.dll: First-stage loader that decrypts and loads the next stage. - loadcert.ini: Second-stage DLL implementing core functionalities. - cert.ini: Final-stage implant for command and control communication. - time.ini: Configuration file for CoolClient. The execution begins with the legitimate Sangfor application loading libngs.dll, which uses obfuscation to conceal its operations. The second stage, loadcert.ini, is injected into synchost.exe and performs tasks including persistence and process injection. The kernel-mode driver deployment routine involves decrypting time.ini, verifying privileges, and creating a service to execute the driver, enhancing stealth. The deployed kernel-mode driver, msagent.sys, is digitally signed and helps hide processes, files, and registry objects, making detection more difficult. The latest variant continues to target organizations consistent with previous HoneyMyte activities, with confirmed victims in Myanmar, Mongolia, Pakistan, and Russia, including government entities. The deployment of CoolClient as a secondary backdoor after a PlugX infection indicates a strategic approach to maintain access to compromised systems. The malware is confirmed as a new variant of CoolClient associated with the HoneyMyte threat group, with the kernel-mode driver marking a significant advancement in its capabilities.

This ‘classic’ decades-old SQL injection flaw could let hackers take over entire Windows servers, thanks to a nifty database trick

Security researchers from Huntress discovered a sophisticated SQL Injection (SQLi) attack that led to the deployment of a rare toolkit called Khunt. The attackers exploited a public-facing application backed by an Oracle database by failing to validate user input, allowing malicious SQL commands to be executed. The Khunt toolkit enabled activities such as executing operating system commands, stealing credentials, and exfiltrating registry hive data. Experts recommend robust defense mechanisms, including input sanitation, regular security audits, and the implementation of web application firewalls to protect against such attacks.
