According to Hunt.io and BleepingComputer, the open-source Hermes AI agent operated in unattended &#8220;YOLO&#8221; mode during activity associated with Thailand&#8217;s Ministry of Finance.<\/p>\n<p>Investigators uncovered exposed infrastructure containing exploit code, web shells, HTTP tunnelling tools, stolen credentials, custom scripts, compiled payloads, Hermes logs, and binaries later identified as the previously undocumented Hades implant. Thailand&#8217;s Ministry of Finance had not confirmed a <a href=\"https:\/\/www.hexnode.com\/blogs\/explained\/what-is-a-breach-in-cyber-security\/\">breach<\/a> at publication, and public reporting notes that some recovered artifacts indicate targeting rather than confirmed compromise.<\/p>\n<p>The incident highlights how AI can accelerate reconnaissance, privilege enumeration, and other post-exploitation tasks, reinforcing the need to detect increasingly automated intrusion activity.<\/p>\n<h2>What the Hermes Operation reveals about AI-assisted intrusions<\/h2>\n<p>Much of the discussion around agentic AI security focuses on defensive use cases. This reported operation shows how attackers may use autonomous AI agents to automate existing post-exploitation workflows.<\/p>\n<p>According to Hunt.io, Hermes was configured to run in YOLO mode, bypassing approval prompts before executing potentially dangerous commands. The recovered logs showed the agent performing tasks commonly associated with post-exploitation, including:<\/p>\n<ul>\n<li>Enumerating files and directories<\/li>\n<li>Searching for <a href=\"https:\/\/www.hexnode.com\/blogs\/what-is-privilege-escalation\/\">privilege-escalation<\/a> opportunities<\/li>\n<li>Inspecting running services<\/li>\n<li>Identifying SUID and SGID binaries<\/li>\n<li>Traversing Linux file systems<\/li>\n<li>Reviewing web directories associated with the Ministry of Finance environment<\/li>\n<li>Processing LinPEAS output<\/li>\n<\/ul>\n<p>None of these techniques are new individually. The notable aspect is the automation layer, which allows operators to delegate repetitive post-exploitation tasks to an AI agent, potentially reducing manual effort after<a href=\"https:\/\/www.hexnode.com\/blogs\/explained\/what-is-initial-access-in-cybersecurity\/\"> initial access<\/a>.<\/p>\n<h2>What the exposed infrastructure revealed<\/h2>\n<p>The investigation began when Hunt.io and security researcher Bob Diachenko identified three exposed web directories hosted on infrastructure in Hong Kong.<\/p>\n<p>Researchers recovered <a href=\"https:\/\/www.bleepingcomputer.com\/news\/security\/hermes-ai-agent-used-to-automate-attack-on-thai-finance-ministry\/?utm_source=hexnode_blog&amp;utm_medium=referral&amp;utm_campaign=hermes_ai_agent_attack\" target=\"_blank\" rel=\"noopener\">585 files<\/a> totalling approximately 470 MB, including:<\/p>\n<table style=\"width: 73.4872%;\">\n<thead>\n<tr>\n<th style=\"width: 30.8249%; text-align: left;\">Recovered artifact<\/th>\n<th style=\"width: 67.8726%; text-align: left;\">Why it matters<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"width: 30.8249%;\">Hermes AI logs<\/td>\n<td style=\"width: 67.8726%;\">Documented Hermes command execution and post-exploitation activity.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\"><a href=\"https:\/\/www.hexnode.com\/blogs\/explained\/what-is-web-shell\/\">Web shells<\/a><\/td>\n<td style=\"width: 67.8726%;\">Suggested remote access capability.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\">HTTP tunnelling tools<\/td>\n<td style=\"width: 67.8726%;\">Included tooling for HTTP tunnelling.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\">Exploit code<\/td>\n<td style=\"width: 67.8726%;\">Indicated exploitation tooling.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\">Custom scripts<\/td>\n<td style=\"width: 67.8726%;\">Referenced Ministry infrastructure.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\">Stolen credentials<\/td>\n<td style=\"width: 67.8726%;\">Indicated operational resources.<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 30.8249%;\">Hades binaries<\/td>\n<td style=\"width: 67.8726%;\">Revealed a previously undocumented implant.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The recovered files referenced Ministry of Finance infrastructure, including Hadoop, Apache Ambari, GlassFish, internal IP addresses, mail systems, and administrative interfaces. However, public reporting does not establish that every referenced system was successfully compromised.<\/p>\n<h2>Hades implant adds another layer to the investigation<\/h2>\n<p>Alongside Hermes, researchers identified Hades, a previously undocumented Go-based implant for Windows and Linux. Hunt.io&#8217;s malware analysis found the recovered samples supported:<\/p>\n<ul>\n<li>HTTPS-based command-and-control communications<\/li>\n<li>File transfer capability<\/li>\n<li>SOCKS proxy support<\/li>\n<li>Windows Registry Run key persistence<\/li>\n<li>Scheduled task persistence on Windows<\/li>\n<li>Cron-based persistence on Linux<\/li>\n<\/ul>\n<p>These capabilities describe the analysed Hades samples rather than confirmed behaviour within the Ministry&#8217;s environment. Public reporting has not established which of these capabilities, if any, were used during the reported activity.<\/p>\n<h2>Why AI-assisted post-exploitation changes incident response<\/h2>\n<p>Security teams have traditionally looked for human-driven attacker behaviour during investigations. Autonomous AI agents may change that expectation. Instead of manually issuing reconnaissance commands, an operator can delegate tasks to an AI agent that:<\/p>\n<ul>\n<li>Executes commands<\/li>\n<li>Processes command output<\/li>\n<li>Identifies potential privilege-escalation paths<\/li>\n<li>Continues operating without user approval<\/li>\n<\/ul>\n<p>This does not make the attack fully autonomous. Public reporting has not identified the initial access method or suggested Hermes independently compromised the environment. Instead, the AI agent appears to have accelerated post-exploitation after access was already available.<\/p>\n<p>For defenders, this may shorten attacker timelines, leaving less time to detect reconnaissance and other post-exploitation activity.<\/p>\n<div class=\"next_blog\"><div class=\"post-next\"><div class=\"hex_blog_box_parent\"><div class=\"blog_warp_next\"><div class=\"next_blog_thumb\" style=\"background-image:url(https:\/\/www.hexnode.com\/threat-watch\/wp-content\/uploads\/2026\/08\/xdr-security-challenges-1.jpeg?format=webp)\"><\/div><div class=\"next_post_content\"><div class=\"center_box\"><h4>Top 10 security challenges XDR helps address for enterprise teams<\/h4><p>Learn how XDR helps enterprise teams overcome key security challenges and improve detection.<\/p><\/div><\/div><\/div><a class=\"hex_blog_box_link hn-cta__blogs--blog-box\" href=\"https:\/\/www.hexnode.com\/blogs\/xdr-security-challenges-enterprise-teams\/\" aria-label=\"Top 10 security challenges XDR helps address for enterprise teams\"><\/a><\/div><\/div><\/div>\n<h2>What Security Teams Should Prioritise<\/h2>\n<p>The incident reinforces several operational priorities regardless of whether an organisation uses AI internally.
