Defaming Botnet Toolkits: A Bottom-Up Approach to Mitigating the Threat
Bibliographic record
Abstract
Botnets have become one of the most prevailing threats to today's Internet partly due to the underlying economic incentives of operating one. Botnet toolkits sold by their authors allow any layman to generate his/her own customized botnet and become a botmaster; botnet services sold by botmasters allow any criminal to steal identities and credit card information; finally, such stolen credentials are sold to end-users to make unauthorized transactions. Many existing botnet countermeasures meet inherent difficulties when they choose to target the botmasters or authors of toolkits, because those at the highest levels of this food chain are also the most technology-savvy and elusive. In this paper, we propose a different, bottom-up approach. That is, we defame botnet toolkits through discouraging or prosecuting the end-users of the stolen credentials. To make the concept concrete, we present a case study of applying the approach to a popular botnet toolkit, Zeus, with two methodologies, namely, reverse engineering and behavioural analysis.

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.
