Darcula PhaaS: A Highly Sophisticated Cybercrime Platform That Exploits Vulnerabilities in SMS-based Attacks


Darcula PhaaS, a highly sophisticated phishing-as-a-service platform, has stolen 884,000 credit cards worldwide through SMS-based attacks. The platform targets Android and iPhone users in over 100 countries and uses advanced phishing techniques to extract sensitive information from unsuspecting victims.

  • Darcula, a phishing-as-a-service (PhaaS) platform, has been linked to a massive cyber heist that stole 884,000 credit cards worldwide.
  • The platform targets Android and iPhone users in over 100 countries, using spoofed domains and RCS/iMessage attacks to extract sensitive information.
  • Darcula's operation is believed to be backed by a Chinese individual named Yucheng, who created and sold the PhaaS platform.
  • The researchers discovered a powerful phishing toolkit called 'Magic Cat' at the heart of Darcula's operation.
  • Despite efforts to shut down the tool, a new version was released, highlighting the adaptability and resilience of the platform.



  • Darcula, a phishing-as-a-service (PhaaS) platform, has been identified as the culprit behind a massive cyber heist that resulted in the theft of 884,000 credit cards worldwide. According to a coordinated investigation by researchers from NRK, Bayerischer Rundfunk, Le Monde, and Norwegian security firm Mnemonic, the platform was used to steal sensitive information from victims who received malicious links via text messages.

    The cybercrime platform, which targets Android and iPhone users in over 100 countries, uses a sophisticated system of spoofed domains that mimic well-known brands. These domains are then used to send out phishing texts that claim to be road toll fines or package shipping notifications, complete with links to phishing sites designed to extract sensitive information from unsuspecting victims.

    The researchers discovered that Darcula was able to use RCS and iMessage instead of SMS, which made its attacks more effective. This ability to adapt and evolve has allowed the platform to stay ahead of cybersecurity measures and continue to attract new operators who are eager to exploit vulnerabilities in the global network.

    One of the most significant breakthroughs in the investigation came when Netcraft researchers identified a powerful phishing toolkit named 'Magic Cat', which is believed to be the backbone of Darcula's operation. The discovery was made possible through reverse-engineering of the phishing infrastructure and infiltration of a Telegram group associated with the platform.

    The researchers also uncovered photos of SIM farms, modems, and evidence of lavish lifestyles financed by the scams. Additionally, they traced the digital footprints of the platform to a Chinese individual, who is believed to be the creator and seller of Darcula. The individual, identified as Yucheng, was reportedly a former employee of a company that claims to sell "website-creation software".

    Despite efforts to shut down the phishing toolkit, a new version was released, highlighting the adaptability and resilience of the platform. The researchers noted that operators are organized into closed Telegram groups, where they communicate in Chinese and run SIM farms and hardware setups to send mass text messages and process stolen cards via terminals.

    The investigation has shed light on the rapid rise of Darcula, a PhaaS platform that has become increasingly sophisticated over the past year. Its ability to adapt and evolve, combined with its use of advanced phishing techniques, has made it a formidable opponent in the world of cybersecurity.

    In conclusion, the Darcula PhaaS platform represents a significant threat to global cybersecurity, and its sophistication is a stark reminder of the evolving nature of cybercrime. As cybersecurity measures continue to evolve, it will be essential for researchers and law enforcement agencies to stay ahead of such platforms and develop effective strategies for combating them.
