Backdoor Attack against Log Anomaly Detection Models (BLOG)

BLOG: Backdoor Attack against Log Anomaly Detection Models

We present BLOG, a backdoor attack framework specifically designed for log anomaly detection models. By embedding carefully crafted triggers into training logs, BLOG enables adversaries to manipulate detection outcomes at inference while preserving benign performance. Empirical results demonstrate that widely used log anomaly detection systems are highly vulnerable, underscoring the need for robust and secure defenses.
