However Microsoft researchers consider this phishing group is a single operation quite than a community of brokers. 

“Whereas many phishing kits are attributed to all kinds of e-mail marketing campaign patterns and, conversely, many e-mail marketing campaign patterns are related to many phishing kits, TodayZoo-based pages solely utilized the identical e-mail marketing campaign patterns, and any of these subsequent e-mail campaigns solely surfaced TodayZoo kits. These lead us to consider that the actors behind this particular TodayZoo implementation are working on their very own,” Microsoft mentioned.
