Breach Summary
Gemini, a U.S.-based cryptocurrency exchange, had the contact information of approximately 5.3 million customers exposed after a dataset surfaced on cybercrime forums in December 2022. The breach did not originate from Gemini's own systems. Instead, attackers used social engineering to compromise employees at Twilio's Authy service, a two-factor authentication provider used by Gemini, and extracted customer data through that supply chain connection. The exposed data consisted of email addresses and partial phone numbers. No passwords, wallet credentials, or financial data were included. Even so, the exposure posed a serious risk to affected users. Cryptocurrency holders are high-value targets, and the leaked contact details were quickly weaponized in phishing and smishing campaigns. Attackers impersonated Gemini support across email, SMS, WhatsApp, and Telegram to steal login credentials or trick users into transferring funds. The data also raised concerns about SIM-swapping attacks, in which criminals hijack a victim's phone number to bypass account security. Gemini confirmed the breach and notified affected customers. No prominent regulatory action or settlement specific to this incident has been documented. Affected individuals remain at elevated risk of targeted phishing, account takeover, and financial fraud, and should treat any unsolicited outreach claiming to be from Gemini with suspicion.

About Gemini
Gemini is a U.S.-based cryptocurrency exchange and financial platform founded in 2014 by Cameron and Tyler Winklevoss. The platform offers buying, selling, and custody of cryptocurrencies alongside a credit card product and institutional trading services. Gemini is regulated as a New York trust company and has positioned itself as a compliance-focused exchange relative to less regulated competitors.
Why They Hold Your Data
Crypto exchanges and custodians collect highly sensitive identity verification records, contact data, financial information, transaction history, device and login metadata, and custody-related account records.
Recent Developments
Gemini has continued building out its regulated exchange and custody operations. The company navigated the broader crypto market downturn of 2022-2023 and the collapse of several competitor platforms. It launched a credit card product and has maintained its focus on institutional and retail custody. Gemini reached a settlement with the New York Attorney General in 2025 related to allegations that its Earn program had defrauded users.

Breach Impact
In December 2022 a dataset of approximately 5.3 million Gemini customer email addresses and partial phone numbers surfaced on cybercrime forums. Gemini confirmed the exposure but attributed it to a breach at a third-party vendor — later identified as Genesis Digital — rather than a compromise of Gemini's own systems. The affected data was limited to contact information. No wallet credentials, trading activity, or financial data was exposed. Gemini notified affected customers and reported the incident. No settlement or regulatory action specific to this vendor breach has been prominently documented beyond the company's general regulatory environment.
Exploitation & Downstream Threats
• SIM swap attacks where phone numbers are present | • Targeted phishing campaigns using exposed email addresses
Principal Risk Advisory
What this means for a principal
A financial-institution breach: account, wealth or payment data supports direct fraud and highly credible financial-impersonation scams. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Guard against SIM-swap and vishing: add a carrier port-out PIN and verify any 'support' calls independently.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping and footprint neutralization: cross-reference against broker-available data and suppress still-removable elements, prioritizing address and phone, since this record re-seeds broker networks.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
