What about using four words… does that work? Well, it does make things more difficult, but again it depends on how commonly used the words are, and how big the attackers dictionary is. f654100d842b2f6f68efeddcec2973bb:SuperfluousExonerateSerendipity CorrectHorseBatteryStaple Restore.Point.: 3616604160/5675964921 (63.72%)Ĭandidates.#1.: OwainLawyersAugury -> OwenSuckedAvertirĬandidates.#2.: OviedoClaudianLatex -> OwainLawyerLeahyĬandidates.#3.: OverysselSightedPreviously -> OviedoClaudiaProclamationsĬandidates.#4.: OverworkInterrogationsWiry -> OverysselSightWoĭe947fd0bbd9f4f5c65a5d802cae1597:RedPantsTree.

The NCSC password was cracked in about 4 hours, with the whole search space, including our uncommon three-word password, completed in around 6.5 hours.

We also added in the NTLM hash for “SuperfluousExonerateSerendipity” to show that even choosing less commonly thought of words is still an issue. All of these words are easily in the top 30,000 most common words, but we decided to attack it with our big dictionary to simulate a more realistic attack time. We took an interest in the example password of “RedPantsTree” given on the NCSC site. Estimates for the number of words that a university-educated person knows is around 40,000 words, so we created a dictionary with the 66,000 most commonly-used words hoping that would cover most of the words that most people would tend to choose, and this reduced our search space by about 17 times allowing us to search all likely three word passwords in only 6 hours! Hmmm, it’s not looking good for ThreeRandomWords… Official recommendation The problem with this advice is that no one knows 171,000 words.

At that speed we could crack a three-word password in around 4 days. One of our dedicated password crackers can search about 20 billion passwords every second from a disk-based wordlist (hashcat benchmark is about 185 GH/s). Yes, that is a lot, but modern GPUs are fast… really fast. If we chose three random words from the words in current use, we’d have a search space of around 5,000 trillion. The English language has a huge number of words – the online Oxford English Dictionary has over 600,000 words however only around 171,000 are in current use. Here’s why they are so important: The numbers The NCSC advice is good in comparison to that low bar.īut we were surprised to see that password managers weren’t in the top 5 actions from NCSC. One of those is breached, which results in other accounts being compromised through password stuffing. but just how strong are these passwords?īefore we go there, we should acknowledge that most people have one or two weak passwords that they use on multiple sites & systems. The National Cyber Security Centre (NCSC) have advocated the use of three random words for several years to create strong passwords, and that advice has been repeated recently by the National Crime Agency, and multiple police forces in the UK….
