Make notifications great again: learning how to notify in the age of large-scale vulnerability scanning
Bibliographic record
Abstract
As large-scale vulnerability detection becomes more feasible, it also increases the urgency to find effective largescale notification mechanisms to inform the affected parties. Researchers, CERTs, security companies and other organizations with vulnerability data have a variety of options to identify, contact and communicate with the actors responsible for the affected system or service. A lot of things can – and do – go wrong. It might be impossible to identify the appropriate recipient of the notification, the message might not be trusted by the recipient, it might be overlooked or ignored or misunderstood. Such problems multiply as the volume of notifications increases. In this paper, we undertake several large-scale notification campaigns for a vulnerable configuration of authoritative nameservers. We investigate three issues: What is the most effective way to reach the affected parties? What communication path mobilizes the strongest incentive for remediation? And finally, what is the impact of providing recipients a mechanism to actively demonstrate the vulnerability for their own system, rather than sending them the standard static notification message. We find that retrieving contact information at scale is highly problematic, though there are different degrees of failure for different mechanisms. For those parties who are reached, notification significantly increases remediation rates. Reaching out to nameserver operators directly had better results than going via their customers, the domain owners. While the latter, in principle, have a stronger incentive to care and their request for remediation would trigger the commercial incentive of the operator to keep its customers happy, this communication path turned out to have slightly worse remediation rates. Finally, we find no evidence that vulnerability demonstrations did better than static messages. In fact, few recipients engaged with the demonstration website.

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.
