What’s occurred?
Just days earlier than Christmas, when most individuals most likely weren’t paying an excessive amount of consideration, password administration service LastPass revealed that hackers had accessed clients’ password vaults.
That sounds actually unhealthy. But wasn’t there information of a LastPass hack earlier within the yr?
You’re most likely considering of the unique announcement LastPass made again on August 25 2022, the place it stated {that a} hacker had managed to realize entry to a developer’s account, and stolen a few of its supply code from a improvement atmosphere.
Back then LastPass stated that it had “seen no evidence that this incident involved any access to customer data or encrypted password vaults.”
So they have been incorrect once they stated that?
Well, LastPass might need not seen any proof that clients’ passwords vaults had been accessed then then, however…
But when an organization says it has “seen no evidence” of something unhealthy occurring, that’s not essentially the identical as saying “nothing bad happened”?
Correct. And certain sufficient, simply earlier than Christmas, LastPass confirmed that the data stolen from a developer’s account within the August 2022 assault was really “used to target another employee, obtaining credentials and keys which were used to access and decrypt some storage volumes…”
Gulp! That sounds a lot worse. So let me get this straight – the theft of the password vaults and different information from LastPass might nicely have occurred in August or September… lengthy earlier than they introduced it as I used to be distracted wrapping Christmas presents?
Perhaps. LastPass hasn’t stated when it believes the theft of the password vaults occurred, however crucial factor to you might be what the stolen information contained, and the way it could possibly be exploited by hackers.
Ok. I’m bracing myself. Tell me the worst…
The stolen information consists of the next unencrypted information:
- firm names
- finish person names
- billing addresses
- phone numbers
- e-mail addresses
- IP addresses which clients used to entry LastPass
- web site URLs out of your password vault
In different phrases, cybercriminals now know that you simply use LastPass, they know tips on how to contact you, they usually know which web sites you utilize.
That’s invaluable data for anybody making an attempt to phish additional data from you, as they may simply pose as one of many web sites you entry and ship you a rip-off e-mail.
Furthermore, merely realizing which web sites you entry (and retailer in your password supervisor) may reveal personal details about you that you’d have relatively stay confidential.
And additional nonetheless, it’s potential you saved password reset hyperlinks for these web sites in your password supervisor which may not have expired, or different delicate data or tokens in your web site URLs that you simply wouldn’t wish to fall into the incorrect arms.
This sound horrible…
Hang on, I haven’t completed.
Because the hackers additionally stole encrypted buyer information together with:
- web site usernames and passwords
- safe notes
- form-filled information
But that’s encrypted, proper?
Yes, it’s encrypted. The hackers want to find out what your LastPass grasp password is, to entry the crown jewels – the usernames and passwords to all of your on-line accounts.
Well, I’ve a robust, hard-to-guess, distinctive password. And I’ve two-factor authentication (2FA) enabled on my LastPass account. So I’m protected…
Hmm, nicely… 2FA is irrelevant on this case. The hackers have already stolen the password vault information, they don’t must hassle logging into anybody’s LastPass account.
Similarly, altering your password now doesn’t undo the information breach. It should be a smart step to take, after all.
And what’s going to assist the hackers is that many many LastPass customers are prone to have chosen grasp passwords which are a lot weaker than LastPass itself recommends.
Since 2018, LastPass says it has really helpful and required a “twelve-character minimum for master passwords”.
Aside from the truth that the variety of characters alone isn’t a superb indicator of password energy, it seems that clients who’ve been with LastPass since earlier than 2018 haven’t been required to replace their grasp passwords to satisfy LastPass’s personal suggestions – leaving the encrypted components of their password vaults rather more susceptible.
It appears like LastPass missed a chance to spice up its customers’ safety there…
Yes, it does relatively.
And what’s extra, safety researchers have revealed that at the least among the grasp passwords saved by LastPass for its longer-standing customers’ vaults have been encrypted in a approach which makes them far too simple to crack.
What do you imply?
As researcher Wladimir Palant particulars, LastPass salts-and-hashes grasp passwords utilizing the PBKDF2 algorithm, with 100,100 iterations.
The variety of “iterations” is a sign of simply how a lot “work” somebody (or extra probably a contemporary graphics card) goes to must do to interrupt your password.
However, many LastPass customers who’ve had their accounts for a very long time seem to have solely had their accounts configured for 5000 iterations, or in some circumstances as little as 500, and even one!
Such poorly-secured vaults might not take too lengthy (or value an excessive amount of cash) to unlock.
And, as LastPass rival 1Password explains, the figures change into a lot worse when it’s a human-created password that the hackers are attempting to crack relatively than a very randomly-generated one.
Oh, by the best way, OWASP’s 2021 steering is for… err… 310,000 or extra iterations…
Years in the past, shouldn’t LastPass have contacted these clients who had a low variety of iterations, and compelled them to spice up their safety?
You would assume that might have been a good suggestion, proper? Years have gone previous, trendy graphics playing cards have gotten sooner at cracking passwords, LastPass failed to raised defend its most loyal clients.

You received’t discover any point out of the information breach on the homepage of LastPass.com both. Which additionally looks like a missed alternative – even when it’s closing the secure door after the horse has bolted…
Blimey. Ok, let’s minimize to the chase. Is my LastPass password vault in danger?
Perhaps.
I’d say your LastPass password vault is extra in danger if a hacker is ready to place the assets into cracking your grasp password. For occasion, if you’re…
- one of many 100,000 companies worldwide that makes use of LastPass
- a journalist
- a authorities employee or politician
- a human rights defender
- a star
- a cryptocurrency investor
- “a person of interest” to an authoritarian regime
I’m not a kind of. I’m simply Joe Schmoe. Could the passwords I retailer in my LastPass vault nonetheless be accessed?
Perhaps. Especially in case your password isn’t as sturdy appropriately, or if you happen to’ve reused your grasp password elsewhere on the web, or if you happen to’re prone to be phished, or if LastPass was not utilizing sufficient iterations to make it tougher to be cracked.
So what ought to I do?
The smart factor to do could be to imagine that your passwords have been, or could possibly be, compromised.
In which case you must change your passwords. And not simply your LastPass grasp password – *all* the passwords saved in your LastPass vault.
Sheesh. That’s going to be lots of effort
I hear you. I’ve over 1600 distinctive passwords in my password vault (I’m not utilizing LastPass, thank goodness), in addition to different paperwork that I wish to stay secured.
Should I ditch LastPass?
That’s one thing solely you’ll be able to resolve.
I really feel unhealthy as a result of LastPass is a product that I’ve really helpful to customers prior to now (they used to sponsor this web site again in 2020, and between 2018-2020 sponsored the “Smashing Security” podcast I co-host).
I’ve all the time been a giant fan of password managers (1Password has additionally been a sponsor of this weblog and the podcast, and Bitwarden at present sponsors “Smashing Security”).
I proceed to consider that utilizing a password supervisor – nearly any password supervisor – is best than not utilizing a password supervisor.
But I can’t carry myself to advocate LastPass now. There are higher decisions on the market.
Where can I study extra?
