Exposed by Default: A Security Analysis of Home Router Default Settings
Bibliographic record
Abstract
With ubiquitous Internet connectivity, home routers have become a cornerstone of our digital lives, often deployed with minimal changes to the factory default settings. However, if left unexamined, these settings can pose risks to user security and privacy. To systematically evaluate potential risks, we developed a threat model-based framework and conducted a comprehensive analysis of 40 commercial off-the-shelf home routers, representative of recent models across 14 brands. We surveyed 81 parameters and behaviors including default and deep default settings. We identified a variety of security flaws including the exposure of IPv6 local devices due to a lack of firewall protection, vulnerable Wi-Fi security protocols, open Wi-Fi networks and trivial admin passwords for "plug-and-play" routers, and unencrypted firmware update communications. We also discovered concealed WPS PIN support --- at times associated with a trivial PIN. In total, we are reporting 30 exploitable vulnerabilities to the vendors. This paper highlights the need for heightened scrutiny of default router settings, providing valuable insights to both manufacturers and consumers for enhancing home network security. Our findings underscore the importance of meticulous device configuration, advocating for proactive measures from all stakeholders to mitigate the threats posed by insecure router default settings.

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.
