Was your data in the LandAirSea breach?

LandAirSea (landairsea.com) suffered a data breach in 2025 that exposed around 337,373 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.

What happened

In January 2025, the GPS tracking service LandAirSea suffered a data breach that exposed 337k unique customer email addresses alongside names, usernames and password hashes. The breach also exposed partial credit card data (card type, last 4 digits and expiration), and GPS device identifiers and locations. LandAirSea is aware of the breach and has remediated the underlying vulnerability.

What was exposed, and why it matters

Not all breaches carry the same risk — what matters is which fields leaked. Here is what the LandAirSea breach exposed and what each item actually enables:

Also listed in this breach: Email addresses, Names, Partial credit card data, Passwords, Physical addresses, Usernames.

What to do if you were affected

These steps are ordered for this specific breach — the most urgent action given what leaked comes first.

1. 01Payment or bank details
   Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
2. 02Passwords
   Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
3. 03Home addresses
   Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
4. 04Names and usernames
   Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
5. 05Email addresses
   Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
6. 06Confirm you were actually in it
   Run a free scan before you spend time on the steps above.

This breach put your details on data-broker sites

Because LandAirSea exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?

This breach is recent, so the data is actively traded and the risk is at its highest right now.

Passwords are the reason breach age matters less than people expect. Leaked credentials are compiled into wordlists that get tried against new services for years afterwards, so a password exposed here is unsafe to use anywhere, ever again.

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.
