What happened
In September 2020, the hotel management & booking platform RedDoorz suffered a data breach that exposed over 5.8M user accounts. The breached data included names, email addresses, phone numbers, genders, dates of birth and passwords stored as bcrypt hashes.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the RedDoorz breach exposed and what each item actually enables:
Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.
Date of birth is a permanent identifier used to verify identity by phone. Combined with a name and address it is often enough to impersonate you.
Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.
Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.
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.
Also listed in this breach: Dates of birth, Email addresses, Genders, Names, Occupations, Passwords, Phone numbers.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Passwords: Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
- Dates of birth: Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
- Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
- Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
- 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 breach is over 6 years old. Old credentials still cause harm — leaked passwords from a decade ago are still tried against new accounts every day.
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.
