Was your data in the Moneycontrol breach?

2017 · moneycontrol.com · ~762,874 accounts exposedCritical severity · 10/10

Moneycontrol (moneycontrol.com) suffered a data breach in 2017 that exposed around 762,874 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 April 2021, hackers posted data for sale originating from the online Indian financial platform, Moneycontrol. The data included 763 thousand unique email addresses (allegedly a subset of a larger 40 million account breach), alongside geographic locations, phone numbers, genders, dates of birth and plain text passwords. The date of the original breach is unclear, although the breached data indicates the file was created in September 2017 and Moneycontrol has stated that the breach is "an old data set".

What was exposed, and why it matters

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

Passwords

Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.

Phone numbers

Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.

Location data

Reveals where you live, work or travel, which supports both targeted scams and physical-safety risks.

Email addresses

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: Email addresses, Genders, Geographic locations, 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.

  1. Passwords: Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
  2. Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
  3. Location data: Review location sharing on the accounts you still hold with this service.
  4. Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
  5. 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 9 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.
