In the movie "The Matrix", finding the "Keymaker" is the key to ending the war. In real life, Initial Access Brokers who provide malicious hackers with access to various enterprises' defense systems have become increasingly active since 2022. They trade effective login credentials in dark web marketplaces. From national-level hackers, ransomware groups to red team service providers, all of them could be potential buyers of those illegal credentials. In many cases of ransomware attacks, achieving initial access is enough to complete their whole destructive incident. The speaker Pei-Kan Tsung (PK) has been analyzing the dark web trading market and the causes of attacking incidents for a long time, and recommends that enterprises should actively seek out the "Keymaker" who can break the locked door of their defense system to proactively prevent potential cyber attacks.
