Interesting Message Stored in Cowrie Logs Published: 2026-03-18. Last Updated: 2026-03-19 00:38:49 UTC by Guy Bruneau (Version: 1) 0 comment(s) This activity was found and reported by BACS student Adam Thorman as part of one of his assignments which I posted his final paper [1] last week. This activity appeared to only have occurred on the 19 Feb 2026 where at least 2 sensors detected on the same day by DShield sensor in the cowrie logs an echo command that included: "MAGIC_PAYLOAD_KILLER_HERE_OR_LEAVE_EMPTY_iranbot_was_here". My DShield sensor captured activity from source IP 64.89.161.198 between 30 Jan - 22 Feb 2026 that included portscans, a successful login via Telnet (TCP/23) and web access that included all the activity listed below captured by the DShield sensor (cowrie, webhoneypot & iptables logs). Bot successfully logged in twice into the sensor on the 15 and 19 Feb 2026 via Telnet. The bot activity of interest was a shell script uploaded on the 19 Feb 2026 in an attempt to exploit IoTs and 64-bit Linux systems. Using Adam [1] grep command, I found in my logs the same script uploaded to the DShield sensor: ubuntu@vps-711a413c:~/downloads$ sudo cat f1c0e109640d154246d27ff05074365740e994f142ef9846634bec7b18e3b715 Script Content Cowrie Log Indicators 64.89.161.198 188.214.30.5 http[:]//188.214.30.5/r.sh f1c0e109640d154246d27ff05074365740e994f142ef9846634bec7b18e3b715 If you detected the same type of activity, we also appreciate feedback and suggestions about what tool might be used to perform these scans.
