AI creates push-button phishing attacks: With the latest update to the “darcula-suite” toolkit, users can now generate phishing pages using generative AI that mimics websites with near-perfect accuracy, and in any language.”Users provide a URL of a legitimate brand or service, and the tool automatically visits that website, downloads all of its assets, and renders an editable version,” Netcraft explained. “Users can then inject malicious content such as phishing forms or credential capture fields directly into the cloned page.”In one demo shared by Netcraft, an attacker cloned Google’s homepage, generated a fake address collection form in Chinese, then translated the entire page back into English, all using the platform’s AI engine. The result was a professional-looking phishing page built in minutes, requiring no coding expertise.This advancement gives threat actors the ability to scale campaigns at speeds previously reserved for advanced APT groups, targeting users in any region with language-specific lures that match their location and device type.Early this year, the phishing platform got a new update that enabled less technical criminals to “build do-it-yourself (DIY) phishing kits that target any brand with the click of a button.”
The defensive challenge: faster, broader, smarter: The real concern is not just the realism of these phishing pages, but the ease and speed with which they can now be produced. “Each phishing page can be different vs. relying on a static number of templates,” the report said. “Traditional signature-based detection methods are increasingly ineffective.”Darcula’s integration of AI also marks a new frontier in the “democratization of cybercrime.” Novice actors with no technical skills can now launch effective, localized phishing campaigns. The customization and multilingual capabilities, combined with high-volume smishing distribution, make detection, takedown, and user awareness far more difficult.”Accessibility, speed, scalability, and evasion, Darcula’s new capabilities check all the boxes for a modern cybercrime toolkit,” Netcraft stated.
Fighting back: beyond traditional defenses: Netcraft, which operates a takedown service for malicious infrastructure, has taken down more than 25,000 phishing sites, blocked nearly 31,000 IP addresses, and flagged over 90,000 domains associated with Darcula since March 2024. But with the AI-powered upgrade now live, the platform’s resilience is expected to grow.”We expect this latest iteration of the Darcula suite to surpass the popularity of its predecessor as the new AI features become more widely adopted within cybercriminal circles,” the report warned.Security leaders should take immediate action by implementing real-time link scanning in messaging applications, deploying behavior-based detection at endpoints, and updating security awareness training to specifically address smishing threats across all messaging platforms. Static URL blocklists and signature-based detection alone will no longer suffice against these dynamically generated threats, the report added.
The growing smishing ecosystem: Darcula does not operate in isolation but is part of a broader criminal network called the Smishing-Triad, which is responsible for orchestrating large-scale smishing campaigns across continents. Netcraft’s previous investigations revealed that Darcula impersonated more than 100 global brands, including postal services, telecom companies, government portals, and banks, using messages sent via compromised SIM banks.Darcula’s global infrastructure, paired with the AI automation seen in the latest update, means that even highly localized or sector-specific brands are not safe. As Netcraft cautioned, “A broader range of targets are at risk with Darcula’s new customization capabilities.”Darcula is not a fringe threat. It is a modern, well-funded phishing engine that uses generative AI to disrupt legacy defenses and scale attacks globally. For security leaders, it signals the arrival of a new class of phishing threats”, one where speed, language, and precision are automated and outsourced. Organizations should revisit their phishing response playbooks immediately. The age of “phishing kits as-a-service” is over. What we are now witnessing is the birth of phishing campaigns at the speed of AI.
