Cybersecurity researchers have successfully demonstrated how Large Language Model (LLM)-powered honeypots can effectively deceive threat actors into revealing their attack methodologies and infrastructure.
Using the Beelzebub honeypot framework, security analysts captured a complete attack sequence that led to the discovery and subsequent shutdown of an active botnet command and control operation.
SSH Honeypot Captures Live Attack Sequence
The attack originated from IP address 45.175.100.69, with the threat actor using common credentials (admin/123456) to access what they believed was a legitimate Ubuntu server.
The LLM-powered honeypot, configured to simulate realistic system responses, successfully maintained the illusion throughout the entire attack sequence.
The attacker began with standard reconnaissance commands, including. uname -a, uptime, and nproc to gather system information.
The honeypot responded with convincing output indicating a Ubuntu 5.15.0-60-generic system with four processors and moderate load averages, encouraging the attacker to proceed.
Moving to the /tmp directory, the threat actor downloaded multiple malicious files from a compromised website at deep-fm.de, which analysis revealed was running an outdated Joomla CMS.
The primary payload was a Perl script disguised as an SSH daemon, along with additional tools packaged in emech.tar.gz.
Botnet Infrastructure Exposed Through Source Code Analysis
The most significant discovery came from analyzing the downloaded Perl script, which contained hardcoded configuration details for its command and control infrastructure.
The script revealed connection details to an IRC-based botnet operating on ix1.undernet.org port 6667, specifically targeting channels #rootbox and #c0d3rs-TeaM.
The malware configuration showed sophisticated operational security measures, including specific administrator handles (“warlock`”) and authorized hosts (“terr0r.users.undernet.org”).
The script was designed as a backdoor capable of executing remote commands and launching distributed denial-of-service attacks against targets specified through the IRC channels.
Technical analysis revealed the botnet used a polling mechanism with 5-second sleep intervals and supported up to 8 simultaneous connections, indicating a design optimized for persistent, low-profile operations across multiple compromised systems.
Coordinated Response Disrupts Criminal Infrastructure
Following the honeypot analysis, researchers successfully infiltrated the IRC channels and observed active botnet operations, including infected systems checking in for commands.
The evidence was promptly reported to Undernet’s abuse team, resulting in the closure of both command and control channels.
This case demonstrates the evolving sophistication of honeypot technology, where LLMs can maintain realistic interactions that convince attackers they have successfully compromised legitimate systems, ultimately leading to valuable intelligence gathering and criminal infrastructure disruption.
