2018's Password Fails

Throughout 2018 I kept a note of all the passwords encountered across 103 onsite penetration tests I was engaged on or peer-reviewed.  From all the passwords, two were extremely memorable:

4minP4ssword! was without a doubt the best worst password encountered for the Administrator user of a windows domain. It is quite surpirsing that this particular password has made a return yet again.

P4ssw0rd! is probably the MOST common password used for initial passwords, with Letmein coming a close second. Yet I encountered the password repeatedly throughout a number of engagements during 2017.

Interestingly, from the pool of passwords gained from the engagements throughout 2018, 11 new passwords were added to my password list out of more than 1,197,000 passwords cracked.

Making a better passwords

The National Cyber Security Centre’s advice to use three random words as a passphrase makes great sense, separating the words with special characters helps make a long, hard to break a memorable password. But, while I do not agree with the NCSC's stance on not needing to change the password, I do believe that you would only need to change the password every six months or so.
