After reading the affidavit it was a former AWS employee. The accused worked there from 2015-2016 and it’s not immediately clear that it was a misconfigured S3 bucket. There’s a particular IAM role she used to execute API commands (ListBuckets, etc..). The buckets contained credit card applications and other data including DOB and SSN. She gloated about it on Slack and said she was using a VPN and Tor.

The affidavit is a good read. Linked elsewhere in this thread.

> hacked into a cloud-computing company server, federal prosecutors in Seattle said > the cloud-computing company, on whose servers Capital One rented space, wasn’t identified in court papers. Does this feel like it was just an S3 bucket with permissions set incorrectly? I've come across sensitive documents in S3 buckets with a well crafted google search.

Per the complaint, it doesn't sound like the bucket was exposed to the world. Rather, security credentials were "obtained": > Capital One determined that the first command, when executed, obtained security credentials for an account named XXXX-WAF-Role, that in turn, enabled access to certain of Capital One's folders at the Cloud Computing Company. Unsure how one would obtain credentials for an IAM Role, but the abov…

It's possible an STS token was obtained using the role. If you're not monitoring where those tokens are issued to and used from, you're gonna have a bad time.

Earlier quoted context omitted.

It says she posted on "social media" (Twitter) about it, claiming to have Capital One information, "and that she recognizes that she acted illegally". Nothing about Opsec here. She basically asked them to arrest her. Probably had some of the usual motivations: "look at me I'm clever", "look at this stupid big company with bad security", or maybe used the opportunity for some political thing with banks. Not the sophis…

Almost certainly deactivated/seized and part of evidence. With some googling you can find her Keybase and other pages aplenty if you like. Almost all her content is scrubbed from the Internet, however. (this person's original comment was asking for her github profile)

Good lord. -Paige left code used in the "attack" on her GitHub. -Paige left text files with unencrypted data there, too. -Paige openly posted about it in an open (!!!) Slack channel and publicly named her VPN service of choice, which of course, matched access logs AND GitHub server logs. (Also tor, which the FBI agent was able to confirm and add yet another data point) -Paige said "I have a leak proof IPredator route…

Hopefully just the vm

Well, the main cloud Capital One uses is Amazon as far as I know. If you think about the attack vectors here, it was most definitely the virtual server that got attacked. If it was the cloud provider (Amazon), there are a lot of safeguards that these banks use to make sure that any data that touches the shared server persistent storage is encrypted. And when I say safeguards, I mean automation to make sure that this…

AWS has Macie to catch this sort of thing, not to mention the usual AWS security automation tools available like Security Monkey. Or the fact that a pen test should have caught this, or employees following the data use policy.

That also links to her gitlab profile which contains her resume/CV in PDF format (among other OSS work).

She did indeed work at Amazon on AWS in 2016 , specifically on s3:

That PDF also contains her home address and other personal information so I'd rather not link directly.

If I came across an s3 bucket with my credit application details and I could delete it, I would probably do it and then report to their security team. It’s MY data security they’re being casual with. It occurs to me now that if I did that it would likely be a crime because of the harm to the company. The irony.

Who cares if it has your data in it or not. Just report it to authorities and the guy who runs haveibeenpwned. Plus what are you going to do with credit card applications anyway? Sell them to a marketing company with some phony story? Or the 'sell them on the darknet to fraudsters in Russia' angle? Unless you're already involved in some dirty business already this isn't very valuable.

I would imagine complete credit card applications contain the type of information identity thieves would be willing to pay good money for.
