What happened
In December 2022, the Crypto & NFT taxes service CoinTracker reported a data breach that impacted over 1.5M of their customers. The company later attributed the breach to a compromise SendGrid in an attack that targeted multiple customers of the email provider. The breach exposed email addresses and partially redacted phone numbers, with CoinTracker advising that the later did not originate from their service.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the CoinTracker breach exposed and what each item actually enables:
Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
- Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
How urgent is this now?
This data has been circulating for around 4 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
Remember: a breach can't be "un-leaked" — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can't, and remove what has been republished.
