|The Australian Cyber Security Centre (ACSC) is aware of a significant data breach affecting 773 million email addresses and usernames.|
Titled ‘Collection #1’, the data breach was made public by Australian cyber security expert Troy Hunt, who identified that a large collection of email addresses, hashed and plaintext passwords had been distributed on a known hacking forum.
|Does it affect me?|
|Unlike other data breaches, this breach cannot be tied down to one site. Instead it appears to comprise multiple breaches across a number of websites/services.|

- Change your password on any accounts where you may have used the same email and password combination.
- Use multi-factor authentication where available to give your accounts an extra layer of security.
