The Darcula phishing-as-a-service (PhaaS) platform has recently integrated generative AI capabilities.
Users can now generate customized phishing pages in multiple languages, complete with tailored form fields and localized translations, all without requiring programming expertise. As a result, even those with minimal technical skills can deploy convincing phishing sites within minutes, extending the potential pool of threat actors.
Darcula is part of a broader cybercrime ecosystem, including platforms like Lucid and Lighthouse, which are believed to be associated with the Smishing Triad—a loosely connected group of threat actors operating primarily from China. These platforms facilitate large-scale SMS-based phishing (smishing) attacks, often impersonating reputable organizations to deceive victims.

Since emerging in March 2024, cybersecurity efforts have led to the takedown of over 25,000 Darcula-related phishing pages, the blocking of nearly 31,000 associated IP addresses, and the identification of more than 90,000 phishing domains.

Analysis
This evolution of Darcula highlights how PhaaS platforms are becoming more accessible and scalable through the integration of generative AI. By allowing users to quickly create multilingual, realistic phishing pages without technical knowledge, Darcula dramatically lowers the barrier for entry into cybercrime. This could lead to a surge in the volume and quality of phishing attacks globally, making it harder for organizations and individuals to recognize scams.
Even before adding AI capabilities, Darcula was already known for its advanced features, including sophisticated link cloaking techniques, dynamic phishing page generation, and robust infrastructure to evade detection. It also supports smishing at scale, integrates tools to impersonate over 100 global brands, and offers services like automated hosting and domain rotation to keep phishing pages live longer.
Its continuous innovation highlights how phishing-as-a-service platforms are becoming more professionalized, posing an increasingly serious threat to cybersecurity defenses.
