Internet-Wide Analysis, Characterization, and Family Attribution of IoT Malware: A Comprehensive Longitudinal Study
Bibliographic record
Abstract
This study presents a large-scale empirical analysis of real-life Internet-of-Things (IoT) malware by conducting a comprehensive analysis of 160,000 malicious executables detected by specialized IoT honeypots over five years. Our findings contribute to improving the knowledge of IoT malware characteristics and inter-relationships, which in return, contribute towards strengthening cybersecurity measures for IoT threat detection/mitigation. To achieve these goals, we leverage various malware analysis techniques to extract useful information from the executable files. Our analysis demonstrate that in contrast to non-IoT malware, we were able to extract unsolicited IP addresses and command strings from the majority of the analyzed IoT malware binaries using off-the-shelf de-obfuscation techniques/tools. Additionally, by correlating the extracted information and performing consequent similarity analysis using NLP-based features, we were able to reveal closely related samples with shared implementation across the adversarial infrastructure. Thus, contributing to labeling previously unseen/unknown IoT malware samples while uncovering emerging, possibly new variants. Finally, given such findings, we discuss the applications of a real-time IoT honeypot, which enables capturing real-time commands from malware-infected IoT devices while enabling timely and effective IoT-malware detection, analysis, labeling, and mitigation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
