PropTiger (proptiger.com) suffered a data breach in 2018 that exposed around 2,156,921 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 2018, the Indian property website PropTiger suffered a data breach which resulted in a 3.46GB database file being exposed and subsequently shared extensively on a popular hacking forum 2 years later. The exposed data contained both user records and login histories with over 2M unique customer email addresses. Exposed data also included additional personal attributes such as names, dates of birth, genders, IP addresses and passwords stored as MD5 hashes. PropTiger advised they believe the usability of the data is "limited" due to how certain data attributes were generated and stored. The data was provided to HIBP by dehashed.com.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the PropTiger breach exposed and what each item actually enables:
Also listed in this breach: Dates of birth, Device information, Email addresses, Genders, IP addresses, Names, Passwords.
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. - 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. - IP addresses
No direct action needed, but be wary of anyone quoting your location as “proof” of identity. - Confirm you were actually in it
Run a free scan before you spend time on the steps above.
How urgent is this now?
This breach is over 8 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.
