What happened
In late 2022, a hacker posted a data set to a public hacking forum which they alleged was sourced from the Gemini crypto exchange, a claim that was later proven to be false as the data was traced back to an incident at a third-party vendor. The source of the breach was later established as being Twilio, who processed the data of some Gemini customers using their Authy service for 2FA. Twilio described the incident as stemming from a sophisticated social engineering attack designed to steal employee credentials.

What to do right now
- Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
