To ensure your name never ends up in a file like this, cybersecurity experts from sources like Aura and SpyCloud recommend:
Behind the lines of text in 2M COMBOLIST CRYPTO.txt are real victims.

These individual leaks were eventually sold to "middlemen" who merged them into larger distributions, like this 2M version, to increase the likelihood of success.
