What happened

In May 2024, 2B rows of data with 361M unique email addresses were collated from malicious Telegram channels. The data contained 122GB across 1.7k files with email addresses, usernames, passwords and in many cases, the website they were entered into. The data appears to have been sourced from a combination of existing combolists and info stealer malware.

Who was behind it

No party has been publicly confirmed as responsible, and this page will not name one. Most breaches are never formally attributed: data surfaces on a forum or inside a combined dump long after the intrusion, and the trail back to a specific actor is rarely made public. Where a group has claimed responsibility it is usually named in the account above — that claim is theirs, not a finding of ours.

What was exposed, and why it matters

What to do if you were in it

  1. Change this password anywhere you reused it, starting with your email account — that is the one that can reset all the others.
  2. Expect better-aimed phishing. A message that already knows your name and where you have an account is the whole point of a breach like this.
