Inferring, Characterizing, and Investigating Internet-Scale Malicious IoT Device Activities: A Network Telescope Perspective
Bibliographic record
Abstract
Recent attacks have highlighted the insecurity of the Internet of Things (IoT) paradigm by demonstrating the impacts of leveraging Internet-scale compromised IoT devices. In this paper, we address the lack of IoT-specific empirical data by drawing upon more than 5TB of passive measurements. We devise data-driven methodologies to infer compromised IoT devices and those targeted by denial of service attacks. We perform large-scale characterization analysis of their traffic, as well as explore a public threat repository and an in-house malware database, to underlie their malicious activities. The results expose a significant 26 thousand compromised IoT devices "in the wild," with 40% being active in critical infrastructure. More importantly, we uncover new, previously unreported malware variants that specifically target IoT devices. Our empirical results render a first attempt to highlight the large-scale insecurity of the IoT paradigm, while alarming about the rise of new generations of IoT-centric malware-orchestrated botnets.

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.
