Convex (convex.ru) suffered a data breach in 2023 that exposed around 150,129 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 February 2023, the Russian telecommunications provider Convex was hacked by "Anonymous" who subsequently released 128GB of data publicly, alleging it revealed illegal government surveillance. The leaked data contained 150k unique email, IP and physical addresses, names and phone numbers.

What was exposed, and why it matters

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

Phone numbers

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

Names and usernames

Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.

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.

IP addresses

Reveals your approximate location and internet provider, which adds credibility to targeted scams.

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. Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
  2. Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
  3. Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
  4. IP addresses: No direct action needed, but be wary of anyone quoting your location as “proof” of identity.
  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 data has been circulating for around 3 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.

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.
