Security expert Troy Hunt, who operates Have I Been Pwned, recently received 2 billion unique email addresses that were found across multiple malicious lists and internet sources, including 1.3 billion unique passwords. Like the 183 million breached email addresses from before , this data comes from an aggregated collection by security firm Synthient, which collates and summarizes from various data leaks.
After processing, the data set now only contains unique credentials (i.e., no duplicate combinations) that were intercepted by Infostealer software. These were either freely available on the internet or could be collected via Telegram groups. You should definitely check the HIBP website to see if your accounts are compromised.
