Threats Affecting Thailand

Noodle RAT, also known as ANGRYREBEL or Nood RAT, is a modular remote access trojan with dual versions for Windows and Linux, actively used by Chinese-speaking threat actors since at least mid-2016. Previously misclassified as variants of Gh0st RAT or Rekoobe, it is now recognized as a distinct backdoor family. The malware has been deployed in espionage and cybercrime campaigns targeting entities across the Asia-Pacific region, including Thailand, India, Japan, Malaysia, and Taiwan. Multiple threat groups including Iron Tiger, Calypso APT, Rocke, and Cloud Snooper have utilized this tool. Both variants feature shared command-and-control architecture, similar configuration structures, and modular capabilities. The Windows version operates as an in-memory backdoor with file management and proxy capabilities, while the Linux variant provides reverse shell, SOCKS tunneling, and task scheduling functionalities. Evidence suggests an actively maintained, possibly commercial malware toolkit.

Gigabud is an Android remote access banking trojan active since 2022, attributed to GoldFactory group, targeting victims across Southeast Asia, South Asia, Middle East, Africa and Latin America. The malware now utilizes Vwork, a weaponized fork of the open-source app cloning application Shelter, to evade detection by creating isolated work profiles. After initial Gigabud infection, Vwork is installed to clone banking applications into the work profile, hiding malicious activity from signature-based detection in application security SDKs. Between February and July 2026, approximately 1,469 compromised devices and 1,281 potentially compromised logins were observed in Indonesia alone, with estimated losses of roughly $960,939. The infection chain involves social engineering through phishing sites delivering fake apps disguised as legitimate services, followed by credential theft through overlays and remote-controlled fraudulent transactions executed within cloned banking apps.

A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček from ESET.

A thriving gray market has emerged offering discounted access to AI models through fraudulent account registrations that exploit free trials and startup credits. Services like Poison Claude and Ecomagent offer 70-90% discounts by creating fake accounts on platforms such as AWS Bedrock and Google Cloud, then reselling access through custom API endpoints. The demand is driven by cost considerations, access restrictions in regions like China, and desire for anonymity. Fraudulent registration campaigns targeting AI video services show over 105,000 brute-force signup attempts using bots, VPNs, and disposable email domains. The operations leverage residential proxies to evade detection and accept cryptocurrency payments. These services operate through sophisticated AI gateways and are advertised on underground forums and messaging platforms, particularly in Chinese-language markets, representing a significant platform abuse challenge for AI service providers.

BlueShell is an open-source remote access trojan developed in Go language, primarily used by Chinese-based threat actors. A variant of BlueShell has been identified in post-intrusion activities by APT groups including BlackTech, targeting organizations in Japan, South Korea, and Thailand. This variant differs from the original through a dedicated dropper mechanism, proxy server-based C2 communication, and anti-forensic capabilities. The dropper deploys the variant to /tmp/kthread, disguises it as a Linux kernel worker process, and removes filesystem traces. Recent variants observed since 2024 include XOR-encoded configuration data and proxy functionality, indicating continuous development. The malware performs hostname verification, validates C2 certificates, and implements commands for file transfer, remote shell, and SOCKS5 proxy capabilities.

Researchers uncovered a fractured criminal ecosystem built around Flying Eagle, an Android remote access tool whose source code was stolen in early 2026 along with nearly 200 customer databases. The investigation began with a malicious APK impersonating a Chinese Provincial Public Security Bureau app, leading to identification of 170 active servers running the framework. Two Telegram channels, SQLRCE0 and Yx Technology, distribute modified versions with operational support and cash-out services at 20-50% transaction fees. The platform combines APK generation and C2 device management with phishing overlays targeting financial, adult, and government services. A successor platform called Night Dragon was introduced in June 2026, featuring enhanced credential capture capabilities for Chinese banking apps, cryptocurrency wallets, and social media platforms. The activity primarily targets Chinese citizens through social engineering lures, though international templates suggest broader targeting capability.

In June 2026, infrastructure pivoting from TencShell C2 nodes revealed an active intrusion campaign utilizing AI language models for attack automation. Thirteen Hong Kong-based servers across four ASNs exposed an open directory containing victim source code, custom exploits, operational logs, and cloned login pages with notes in Simplified Chinese. The operation employed Claude Code for execution and DeepSeek-v4-pro for attack logic, targeting government systems in Afghanistan, Thailand, and Taiwan, along with reconnaissance against U.S. government portals. The campaign also pursued financial services firms across Europe, Australia, and Asia. Attackers deployed TencShell implants, webshells, and custom exploits including SQL injection and Laravel deserialization attacks, successfully compromising administrative systems and exfiltrating sensitive data including citizen complaints and government employee information.

Beginning in August 2025, a sophisticated intrusion was discovered where attackers used log poisoning techniques to deploy a web shell on vulnerable phpMyAdmin panels. The threat actors exploited misconfigured web applications to plant China Chopper web shells, controlled via AntSword, before deploying Nezha, an open-source monitoring tool, to facilitate remote command execution. This led to the deployment of Ghost RAT on compromised systems. Analysis revealed over 100 compromised machines, predominantly located in Taiwan, Japan, South Korea, and Hong Kong. The attackers demonstrated technical proficiency through multi-stage operations, utilizing AWS and VPS infrastructure, with indicators pointing to China-nexus threat actors. The campaign highlights increasing abuse of legitimate publicly available tools to achieve malicious objectives while maintaining plausible deniability.

The Gentlemen ransomware-as-a-service group emerged as a top-10 threat actor in the first half of 2026. The group exploits vulnerabilities in internet-facing devices like VPNs and firewalls, potentially collaborating with initial access brokers. They employ comprehensive reconnaissance using tools like SharpADWS, NetScan, and Advanced IP Scanner, capturing network traffic with netsh. The attackers disable security products through BYOVD techniques using vulnerable drivers, and deploy custom Go-based backdoors and ransomware variants. They spread laterally via GPO deployment and PsExec, encrypt files using Curve25519 and XChaCha20, and recently developed a C-based ransomware variant using AES256-GCM and RSA. The group targets multiple industries worldwide, particularly in Brazil, China, Indonesia, Taiwan, and Thailand, with attacks focusing on manufacturing, IT services, healthcare, and financial sectors.
