4iQ co-founder and CTO, Julio Casal first reported  the aggregated combo list of 1.4 Billion clear text passwords that has been getting a lot of media attention this week. 

Although breaches within this combo list are already known and have been circulating for a while now, he discovered that there are 463M unique passwords with around of them 143M being new. 

Out of this trove, sadly, the top password is 123456, followed by 123456789, qwerty, password and 111111. 

Business need to keep in mind employees and partners use weak passwords and even reuse them for company use, including corporate emails. 

An outside approach to make sure your domain is safe is more and more becoming a smart cyber security practice.
