The group of people took a list of user names and passwords from a different breach and tried them on trello to see if people used the same password and wrote down which ones did.
Nothing a company can possibly do to stop this, only users can.
Even if the company required 2 factor authentication to fully log in, getting this far would still confirm each account/password combo was correct, which is all the "hackers" did.
This isn't completely true, but it is the current standard.
A website can detect and block many user/password attempts from the same IP and block IPs that are suspicious.
Websites can detect elivated login fails across many IPs are react accordingly (It may be reasonable to block all logins for a time if they detect an attack like this)
I'm sure there are other strategies, I don't know how often they are actually employed, but I wish companies would start taking this sort of attack more seriously (even if it's not at all hacking)
Yes but this wasn't a data breach. This was a data stuffing incident, meaning they took someone else's data dump and tried their email and credentials here.
never use the same username and password in two or more places
always use MFA, a hard token if you can like a yubikey
For project tools like Trello, a good portion of your userbase is company emails. A malicious actor now has a list of company emails that they can compare against public facing data like Linkedin, imitate a user using a gmail based off their name, sending an email to that company's IT team asking for an MFA reset sent to the newly created gmail account. Now imagine if that compromised user is a developer with admin access to production environments. These were the conditions for various ransomware attacks.
An email, username, real name are not much, but it's a foot in the door.
I agree that data security is important, even if it is only email addresses, where many are probably findable in the web anyway. Maybe, the link with the username has some value, but I’d bet only little.
In my opinion, harsh penalties are more needed in privacy invasive (in my opinion malware) like google, meta, Amazon etc. are spreading.
The problem is that this data can be combined with other data. An email address by itself isn't particularly important but when it's matched up with names, physical addresses, DoB, SSN, other PII and the network of other services with matching data it becomes very serious.
It's never just this breach, it's every other breach as well. Every breach makes every preceeding breach more effective and more valuable.
I work for a small (but successful) company that is starting to get their shit together and actually build resources instead of saying "Well, just do what we did 3 years ago" to someone who has no idea what they're talking about
I exclusively use alias emails and have found the down side. If you use an alias email for each site you visit (let’s say an online shop that is ran by Shopify) there is an extremely high chance your purchase will be flagged (fuck you Shopify) as a fraudulent account. I am constantly being flagged on sites with Shopify back ends for fraud. It really sucks when your hoppy (FPV Drones) is mainly ran by Shopify sites.
P.S. There is no one to help resolve these issues with Shopify as they don’t have a customer support unless you’re a customer and the store owners are either dumb on how to help or just plain lazy.
"Breached" implies that sensitive data, like payment details, private communication, or physical addresses, were leaked. Instead, this is just semi-public stuff like email/username/name. Maybe a better title would be "15M Trello users have been identified (name/email)"
Of course. But are you sure “identified” is correct word here? I chose “breached” because title of mail was “You're one of 15,111,945 people pwned in the Trello data breach”
I think it's reasonable that you chose that title based on the email header, and I also think it's very irresponsible of haveibeenpwned to send out an email with that subject line. They absolutely should know better.
Funny. Back in my l337 days public Trello boards were one of the easy ways to get passwords. People would put shared passwords for team accounts just on their board, in plain text
That title is very misleading. 15M Trello accounts were found to be compromised because of other, previous leaks, but no leak related to Trello occurred.
Maybe « 15M Trello accounts compromised from previous leaks »? I tried to keep it short but not so short that it would be misleading, dunno if the right balance is there.
It's a kanban board that atlassian a popular company that makes apps for developers bought out.
Not sure if you used a kanban board before but basically you put items that need to be done in columns with typical headers (can be changed) of "to do, doing, blocked, done". So that one can keep track of work/goals etc.
With a site that active, they really need something that can’t identify strange traffic patterns. Hell, maybe they do but no one cared to do anything. Maybe no one listens to IT… that never happens /s
Yeah mostly for spam but the dataset is massive. 15M emails + real names + usernames is pretty useful for any cold emailing like recruitment and product spam. That being said, using datasets like this legally is a no-no but it's almost impossible to prove either way.
