The Stiiizy Data Breach: Lessons for Mitigating Third-Party Security Risks

STIIIZY, a renowned cannabis brand in California, experienced a significant data breach when their point-of-sale (POS) vendor was targeted by hackers. The breach, disclosed in November 2024, resulted in the theft of sensitive customer information, demonstrating the severe risks posed by unmonitored third-party connections.

What Happened in the Breach?

The breach occurred when an organized cybercrime group accessed STIIIZY’s POS vendor systems between October 10 and November 10, 2024.

The attackers stole a variety of highly sensitive customer data, including:

• Government-issued IDs (e.g., driver’s licenses and passport numbers).
• Names, addresses, and dates of birth.
• Photographs and signatures from government IDs.
• Detailed transaction histories across multiple locations.

• STIIIZY Union Square, San Francisco, CA
• STIIIZY Mission, San Francisco, CA
• STIIIZY Alameda, Alameda, CA
• STIIIZY Modesto, Modesto, CA

The breach affected approximately 380,000 customers, compromising their privacy and financial security. The challenge for these types of breaches is that most enterprises don’t have visibility into their third-party app ecosystems.

Response and Mitigation Efforts

1. Enhancing security protocols to prevent further unauthorized access.
2. Collaborating with law enforcement to investigate the cybercriminals.
3. Offering 12 months of free credit monitoring and proactive fraud assistance to affected customers.
