Gigabud Creates Android Work Profiles to Hide From Banking App Malware Checks

The Gigabud banking trojan installs a secondary Android application called Vwork, which creates a work profile on compromised devices to evade detection from banking app security measures. This work profile separates its contents from the personal space of the device, allowing fraudulent transactions without triggering alerts. Group-IB confirmed this operational chain in Indonesia, where Gigabud has been active since 2022 and is linked to the GoldFactory group, which uses deceptive tactics to distribute the trojan. Vwork simplifies the creation of a work profile and communicates with an external server for authorization before cloning apps. The report indicates that Vwork has been detected in various countries, while approximately 1,469 devices and 1,281 logins were compromised in Indonesia, leading to estimated losses of around ,000,000. Users can check for a work profile in their phone's settings and are advised to download apps only from official stores and to deny unnecessary Accessibility access.

Pterodactyl Multi-Game Cloud Server: 13 Steps [2026]

In 2026, hosting game servers has become more efficient, allowing multiple game servers to run on a single cloud VPS using Pterodactyl Panel, which utilizes Docker containers for isolation. Pterodactyl is a free, open-source game server management panel that gained popularity due to its user-friendly interface and robust architecture. The latest stable release, v1.12.0, was launched in January 2026, with newer deployment templates available as of August 2026. To set up Pterodactyl, prerequisites include a cloud VPS with specific CPU and RAM requirements, Ubuntu 24.04 LTS, PHP 8.3, MariaDB 11.8.8 or newer, Redis 8.10.0 or newer, Docker Engine, a registered domain for SSL, SteamCMD dependencies, and at least 80 GB SSD storage. The installation process involves provisioning the VPS, installing necessary software, configuring Pterodactyl, setting up Nginx with SSL, and deploying game servers. Common pitfalls include under-provisioning RAM for resource-intensive games, neglecting firewall settings, and allowing backup retention to grow uncontrollably. Troubleshooting may involve addressing PHP-FPM issues, connection problems, and ensuring proper resource allocation. Advanced scaling may require multiple VPS nodes, and security measures like two-factor authentication can help protect the server. Pterodactyl is free to use commercially and can run multiple game containers on a single node.

Gemini overlay gets bubble minimization and multitasking on Android

The latest update to the Gemini overlay on Android introduces a multitasking feature with a "Minimize" button that allows users to reduce the overlay into a floating bubble shortcut. This bubble appears after entering a prompt and generating a response, and it is anchored to one of six predetermined positions. Users have reported a bug that resets the bubble to the bottom-right corner when minimized. Tapping outside the sheet restores the bubble, and users can also use the system back gesture to close the overlay or drag to dismiss it. The rollout of this feature is currently underway for Android users.

Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, mimicking a customer service representative. It features a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent can respond to customer queries, calculate service prices, manage acceptance or rejection of services, propose appointment time slots, and confirm booking details. The agent operates in two persistence modes: in-memory for quick testing and Postgres for durability. Testing can be conducted locally with Streamlit or using Docker to simulate a production environment. Docker allows the application to interact with a PostgreSQL server without local installation, enhancing reproducibility. The project includes a docker-compose.yml file to initiate a PostgreSQL container, and users can also utilize a cloud-based Postgres solution. The application behavior remains consistent regardless of the database setup. The complete source code is available on GitHub for testing and further enhancements.

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.

Migrate Vaultwarden to PostgreSQL: Scale for Teams [2026]

Self-hosting Vaultwarden with SQLite can lead to performance issues as the user base grows, particularly due to SQLite's limitations with concurrent writes. Transitioning to PostgreSQL allows for better performance, multi-user support, and enhanced data durability. PostgreSQL supports concurrent connections and row-level locking, making it more suitable for team environments. To migrate from SQLite to PostgreSQL, certain prerequisites must be met, including having an existing Vaultwarden deployment, Docker Engine, a PostgreSQL server, and pgloader installed. The migration process involves backing up existing data, deploying a PostgreSQL container, updating configuration files, and using pgloader to transfer data. A VPS with 2 vCPU and 4GB RAM can support up to 50 users, with larger teams requiring more resources. PostgreSQL also allows for the creation of organizations for shared vault access and the configuration of group policies for security. Regular backups and performance tuning are necessary to maintain optimal operation. Common pitfalls during migration include not stopping the Vaultwarden container before migration, failing to encode special characters in the database password, and neglecting to back up data. Troubleshooting may involve checking connection strings and ensuring the PostgreSQL container is healthy. Advanced configurations can enhance performance and functionality, and understanding the differences between Vaultwarden and Bitwarden's official self-hosted server can aid in decision-making.

Migrate Amazon Aurora PostgreSQL across major versions with active Debezium CDC connectors using native logical replication

Organizations using Debezium Change Data Capture (CDC) connectors on Amazon Aurora PostgreSQL-Compatible Edition face challenges during major database version upgrades. In-place upgrades require downtime, while blue/green deployments disrupt CDC event pipelines. A method using PostgreSQL's native logical replication allows migration between a source cluster (current version) and a target cluster (new major version) without a full connector re-snapshot. This approach minimizes risks of data loss and allows existing Debezium connectors to operate on the source during synchronization. The cutover process involves disabling the replication subscription, synchronizing sequences, creating a new Debezium replication slot on the target, and redirecting the connector, resulting in a brief pause for Kafka consumers. Prerequisites for this method include enabling logical replication on the source cluster, ensuring the target cluster is provisioned in the same VPC, and confirming that tables participating in CDC have primary keys. The process involves configuring parameter groups, creating publications, and establishing subscriptions for logical replication. During cutover, application writes are halted, and replication lag must be monitored to ensure it reaches zero before proceeding. After the cutover, ongoing monitoring of replication health and Kafka consumer offsets is necessary. Common failure scenarios include Aurora writer failover, Debezium connector stalls, large messages exceeding Kafka limits, DDL changes during synchronization, and long-running transactions blocking lag drain. Each scenario has specific symptoms, detection methods, and resolutions. Post-migration, organizations should establish monitoring for replication lag growth and Kafka consumer offset divergence. Automation can streamline the migration process for organizations managing multiple clusters, utilizing AWS Cloud Development Kit (CDK) constructs for cluster provisioning, schema replication, and cutover orchestration. After verifying stable operation on the target cluster, the old Debezium connector and source cluster can be decommissioned. Limitations include the absence of failover slots on Aurora PostgreSQL 17 and the need to handle TOAST columns appropriately.

Big Walk: So, what’s the deal with that number puzzle?

Players in Big Walk can find a prize called a nubbin inside a frosted glass container near the beach, marked by two four-digit numbers. The numbers 4166 and 1899 are coordinates (latitude and longitude) that lead to the button's location on the island. To solve the puzzle, players need to first place five nubbins atop the red tower to access a map room. The map indicates that the button is located east and south of the starter hub, with specific measurements derived from the numbers. A small button is hidden behind a rock, and one player must hold it down while another retrieves the nubbin. Players can also use a GPS device to assist in locating the button.
