A Hybrid System to Find & Fight Phishing Attacks Actively

Traditional anti-phishing methods and tools always worked in a passive way to receive users´ submission and determine phishing URLs. Usually, they are not fast and efficient enough to find and take down phishing attacks. We analyze phishing reports from Anti-phishing Alliance of China(APAC) and propose a hybrid method to discover phishing attacks in an active way based on DNS query logs and known phishing URLs. We develop and deploy our system to report living phishing URLs automatically to APAC every day. Our system has become a main channel in supplying phishing reports to APAC in China and can be a good complement to traditional anti-phishing methods.
