Threat Intel - Interesting Message Found in Cowrie Logs
Basically, a student found a strange message in security logs that could hint at a cyber threat.
A student discovered a strange echo command in cowrie logs. Detected by DShield sensors, this could indicate probing by a cyber threat. Understanding this activity is crucial for future defenses.
What Happened
On February 19, 2026, a notable activity was recorded in cowrie logs, which are used to capture interactions with honeypots. This discovery was made by BACS student Adam Thorman as part of his academic assignment. The logs revealed an echo command that contained the phrase: "MAGIC_PAYLOAD_KILLER_HERE_OR_LEAVE_EMPTY_iranbot_was_here". This unusual message suggests some form of experimentation or probing activity.
The detection came from at least two sensors managed by DShield, a well-known network threat detection service. Such logs are critical for understanding potential threats, as they can provide insights into the tactics used by cyber adversaries.
Who's Behind It
The source of this activity was traced back to the IP address 64.89.161.198. Between January 30 and February 22, 2026, this IP engaged in various activities, including port scans and a successful login via Telnet on TCP port 23. The presence of the echo command, combined with these actions, raises questions about the intentions of the actor behind this IP.
This incident highlights the importance of continuous monitoring and analysis of network traffic. The use of Telnet, a protocol known for its vulnerabilities, indicates that the actor may have been testing the waters for further exploitation.
Tactics & Techniques
The echo command found in the logs is particularly intriguing. It appears to be a form of signature or marker left by the actor, possibly to identify their presence or test responses from the honeypot. Such tactics are common among threat actors who want to gauge the defenses of a target before launching a full-scale attack.
Understanding these techniques can help cybersecurity professionals anticipate potential threats. The use of cowrie logs and similar honeypots can provide invaluable data for threat intelligence and incident response.
Defensive Measures
Organizations should consider implementing robust monitoring solutions to detect similar activities. Regularly reviewing honeypot logs can uncover unusual patterns that may indicate probing or reconnaissance efforts by threat actors.
Additionally, ensuring that all systems, especially those using protocols like Telnet, are secured and monitored is crucial. Employing more secure alternatives, such as SSH, can help mitigate risks associated with vulnerable protocols.
In conclusion, while this specific incident may seem isolated, it serves as a reminder of the ongoing threats in the cybersecurity landscape. Continuous vigilance and proactive measures are essential to stay ahead of potential attackers.
