All of us must know by now that passwords which might be straightforward to guess will get guessed.
We not too long ago reminded ourselves of that by guessing, by hand, 17 of the highest 20 passwords within the Have I Been Pwned (HIBP) Pwned Passwords database in beneath two minutes.
We tried the ten all-digit sequences 1, 12, 123 and so forth as much as 1234567890, and eight of them have been within the high 20.
Then we tried different apparent digit combos akin to 000000, 111111 and 123123 (we began with six digits as a result of that’s Apple’s present minimal size, and since we famous that 123456 got here out properly forward of 12345 and 1234).
The others have been equally straightforward: qwerty, password, abc123, password1, iloveyou and qwertyuiop, the final being a helpful reminder that size alone counts for little or no.

We did get the opposite three passwords in a while after a bit extra work.
One was the apparent sample 1q2w3e4r5t – we initially gave up making an attempt at 1q2w3e4r, however ought to clearly have thought to go additional, on condition that two different 10-character keyboard patterns had already confirmed up in our record.
And we must always have thought to strive the Chinese language zodiac, which might have revealed the 6-letter passwords monkey and dragon, which completed off the record at #19 and #20 respectively. (Due to the Bare Safety readers who wrote in to inform us!)
As you possibly can see above, these passwords didn’t simply present up as soon as every within the many public password dumps that have been discovered and processed by HIBP, however actually tens of millions of instances, with 123456 on the high with greater than 24 million appearances, and dragon on the backside with 994,142.
So we have to select higher passwords, and whereas 99pass!!word45 might be nearly secure sufficient (however don’t use it – you possibly can simply do higher!), a very long-and-strong string akin to yjCMth15SU,atTWT? is the kind of password you must be aiming at.
In case you’re questioning, that’s a mnemonic password that you could recall with the phrase “You simply can’t make these things up, ain’t that the entire fact?”.
Sturdy sufficient for every part?
The issue is that a few of us nonetheless appear to assume that after we now have memorised a really long-and-strong password, we’ve mainly solved the password downside.
Merely put, there’s nonetheless a college of thought that goes like this:
- The password
password1is a nasty concept. It’s all the time dangerous, so that you shouldn’t use it anyplace. - The password
99pass!!word45is secure sufficient, so long as you solely ever apply it to one website. - However
huEX+IDszSSMcBjMw/S9kAis SUCH A GOOD PASSWORD that you simply would possibly as properly use it in all places, as a result of nobody will ever determine it out.
Till they do determine it out, in fact.
As we defined earlier this week, cybercrooks usually acquire passwords without having to guess them or crack them algorithmically, for instance:
- If a sloppy web service shops your password in plaintext after which will get breached, the crooks purchase your precise password straight, no matter how complicated it’s.
- Keylogging malware in your pc can seize your passwords as you kind, thus acquiring them “at supply”, irrespective of how lengthy or bizarre they is likely to be.
- Reminiscence-scraping malware on hacked servers can sniff out uncooked passwords whereas they’re being checked, even when the password itself by no means will get saved to disk.
Enter credential stuffing
Password re-use is why cybercriminals use a trick known as credential stuffing to attempt to flip a hack that labored on one account right into a hack that can work on one other.
In spite of everything, in the event that they know that one in every of your accounts was protected by yjCMth15SU,atTWT?, it prices nearly nothing in time or effort to see if any of your different accounts use the identical password, or one which’s clearly associated to it, giving the crooks a two-for-the-price-of-one assault.
(By “clearly associated” we imply that if the crooks purchase a password record that reveals your Fb password was yjCMth15SU-FB, they’ll in all probability strive yjCMth15SU-TW for Twitter and yjCMth15SU-GM for Gmail, as a result of that kind of sample is reasonably apparent.)
And, in line with the US Division of Justice (DOJ), that’s how an alleged cybercriminal known as Charles Onus, who was arrested earlier this yr in San Francisco, is claimed to have made off with a tidy $800,000 in just some months.
The suspect, claims the DOJ, merely tried the already-known passwords of 1000’s of customers in opposition to their accounts on a web based payroll service in New York.
We’re assuming it was attainable to guess which potential victims have been customers of the payroll service just by their e mail addresses.
If the handle matched (or maybe the individual’s social media profile gave away) the title of an employer that used the service…
…then it was a very good guess that they’d have a payroll account with the identical e mail handle, and due to this fact additionally a worthwhile legal experiment to see if they’d the identical password.
Onus, says the allegation, was capable of login unlawfully to at the least 5500 completely different accounts utilizing this easy system – so easy that it doesn’t even really matter as “hacking”.
He was then apparently capable of change the checking account particulars of some customers in order that their subsequent wage cost went right into a debit card account that he himself managed, and to skim off a whopping $800,000 between July 2017 and the beginning of 2018 or thereabouts.
What to do?
- Don’t re-use passwords. And don’t attempt to invent a way for modifying every password barely from an authentic template to make them appear completely different, as a result of the crooks are looking out for that.
- Contemplate a password supervisor. Password managers generate random and unrelated passwords for every account, so there aren’t any similarities a criminal may determine, even when one of many password will get compromised. Do not forget that you don’t should put all of your passwords into the supervisor app should you don’t wish to: it’s OK to have a particular manner of coping with your most essential accounts, particularly should you don’t use them usually.
- Activate 2FA should you can. Two-factor authentication doesn’t assure to maintain the crooks out, however it stops assaults like this one from being carried out so simply and on such a broad scale, as a result of the passwords alone wouldn’t have been sufficient.
- Report cost anomalies. Clearly, it’s worthwhile to search for outgoing funds that shouldn’t have occurred, and for incoming funds that by no means arrived. But in addition look out for outgoing funds that someway failed when they need to have gone by means of, or for incoming funds you didn’t count on, irrespective of how small the quantity. The earlier you report any errors, even should you didn’t lose any cash, the earlier you assist each your self and everybody else.
