How to secure yourself from the Collection #1?

摘要

The Have I Been Pwned? (HIBP) website has revealed another huge cache of breached email addresses and passwords discovered last week circulating among criminals. Named "Collection #1", its statistics are as impressive as they are worrying: 87GB of data, 12,000 files, and 1.16 billion unique combinations of email addresses and passwords. After cleaning up the data, Hunt reckons 773 million email addresses are unique, as are 21 million of the passwords, which is to say appearing in unhashed form only once within the cache. Hunt said the data was discovered by "multiple people" on the MEGA cloud service being advertised as a collection made up of 2,000 or more individual data breaches stretching back some time.
