361 million stolen accounts leaked on Telegram added to HIBP

A massive trove of 361 million email addresses from credentials stolen by password-stealing malware, in credential stuffing attacks, and from data breaches was added to the Have I Been Pwned data breach notification service, allowing anyone to check if their accounts have been compromised.

Cybersecurity researchers, who wished to remain anonymous, collected the credentials from various Telegram channels.

The resulting 122 GB dataset was shared with Troy Hunt, who says it contains 361 million unique email addresses.

New breach: Last week, 361M unique email addresses were collated from malicious Telegram channels. Data also included passwords and often, the website they were entered into, captured by info stealer malware. 58% were already in @haveibeenpwned. More: https://t.co/5DSTy4xfLN

X (formerly Twitter)

Last week, the same researchers shared a sample of this data with us that contained BleepingComputer forum accounts.

All of these credentials were stolen via information-stealing malware based on the format (url:name:password) of the data.

@BleepingComputer Blurring can often be undone. Best to obliterate it with solid colour.
@apicultor @BleepingComputer Normally I hate a reply-guy thing like this, but you have a very valid point given the nature of the data blurred here.
