Descomplica (descomplica.com.br) suffered a data breach in 2021 that exposed around 4,845,378 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 March 2021, the Brazilian EdTech company Descomplica suffered a data breach which was subsequently posted to a popular hacking forum. The data included almost 5 million email addresses, names, the first 6 and last 4 digits and the expiry date of credit cards, purchase histories and password 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 Descomplica breach exposed and what each item actually enables:
Direct financial fraud, plus convincing scam calls that quote your real card or account details to establish trust.
Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.
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: Email addresses, Names, Partial credit card data, Passwords, Purchases.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Payment or bank details: Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
- Passwords: Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
- 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 data has been circulating for around 5 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
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.
