From what I can tell, I don't think this was a really 'bad' breach... I found the woman's name, and a link to her still-active (as of yesterday) Twitter acct.
She got herself caught by admitting to what she did on at least one public website. I saw her twitter thread referencing it from a few days earlier.
She also mentioned that the data she had was encrypted, and wanted to get it off her server. Given that statement, I don't think she had the tools to crack the encryption (and if CapOne was smart, they hashed / salted the data).
She had a small IT business of her own in the Seattle area.
Looks like she'll be going to prison for a few years.
No, I don't have concrete evidence that this is 'no worries'... just from the info I can see, she doesn't look like a serious hacker / able to exploit the data.
While I don't give companies a lot of slack for data breaches (almost always avoidable, and inexcusable, if good practices are followed, but that's another thread), I will give Capital One credit for getting out in front of this early, and publicly, within days of it occurring.
As an aside, but related - There's now a site to go to for the Equifax data breach to file claim for reimbursement, if you were affected by their breach a couple of years ago (150 million ppl, and they sat on the knowledge for many months before disclosing it.)
$125 base payment (or 10yrs of credit monitoring, if you don't already have it), and you can *also* file for $25/hr for up to 20hrs of expenses (up to 10hrs doesn't require documentation; only your description of what you did and how long it took).
Website below (it's legit; I filed my claim a couple of days ago, as I was impacted (and thankfully, nothing adverse has happened. I have credit freezes active with all three reporting agencies, and I get weekly reports on my credit records.))
I've read that the 'anticipated' amount of respondents is about 281K (of 150 million? WTF?), so put your claim in quickly if you want reimbursement (which will be awarded a few months from now.)
Personal information of millions of people was impacted. Find out if you are part of the settlement and the benefits you may receive.
