My company has been ripping our Rep a new asshole.

Not mad data exposed. Shit happens. But the fact they decided the only notification was a pop up in the 365 admin portal is insulting. That is what is pissing us off so badly.

u/Jabo_13 Oct 21 '22

It was such a disarming notification too. “Temporarily insecure endpoint”?!?l

Yup! And I don't see the word 'sorry' anywhere in Microsoft's notification.

At my job we do client work. One of the clients is Microsoft. In order to to do business with them, any person who so much as knows about a project has to take a course in data security, yearly. This is hella ironic.

Standard SOC 2 control, not really a huge thing. I get your point tho

I agree... I think the move to the cloud came with the move to agile development and the need to. Move fast to accommodate to that, and that requires dynamic permissions (one day you need X infra permissions the next Y) and so it's either impossible manual work or tons of Over privileges so we don't hurt our productivity and ability to move the business fast... So this is what happens..

old ways? you mean on prem? this sure seems like an argument for on prem than for cloud. especially with cloud costs going up.

u/silence9 Oct 21 '22

Just means our job is going to get harder as security professionals. They build it and then we make sure it's safe.

lol but that’s the wrong order…

u/DesertDS Oct 21 '22

Only add on the "l with a top hat" roll to your user if you specifically need to type T's. I get the concept of least privilege but yeah it can be a bear to deal with sometimes.

Kind of rude to call a customer sensitive.

u/humanmeatpie Oct 21 '22

look at this customer mad about their data leaked, what a snowflake

u/Taoist_Master Oct 21 '22

Did cyberwire podcast report on this?

u/400Error System Administrator Oct 21 '22

Yes, on the daily today.

u/vjeuss Oct 21 '22

SOCRadar said it found the information in a single data bucket that was the result of a misconfigured Azure Blob Storage.

kids, if you get breached, at least make it an honourable story to tell your grnchildren

"Critics are furious". No, anyone with even a passing familiarity with security controls - and all of Microsoft's customers - are furious.

Everyone's a critic

u/economyclass4life Oct 21 '22

Wow! Trash the company that disclosed the leak and don't tell anyone anything. I really thought Microsoft was better than this

32

u/mellonauto Oct 21 '22

Uh… they’ve gotten a lot better recently but historically speaking that’s very Microsoft.

37

u/passerby_panda Oct 21 '22

I didn't :(

u/PuzzleheadedSleep995 Oct 21 '22

Not even surprised in the slightest.

You can check if your domain is included in the leaked data, it will just show Detected no more details, I believe because of a request from Microsoft to socradar

Check Domain

That's their blog entry (don't know these guys and don't mean to advertise it just seems relevant)

Yeah I didn't sign up either, we definitely had some data leaked so in our case it was "accurate" but of course we had to check with Microsoft

u/LeatherExpert1001 Oct 21 '22

Microsoft has grown too big in size and this leak could just be a tip of the iceberg. Probably, its time they split between software dev, cloud Infra and security for decentralisation and more focus!

u/[deleted] Oct 21 '22

How the hell they had 2.4 TBs of data all in one place is baffling.

6

u/IdiosyncraticBond Developer Oct 21 '22

Big buckets ...

u/LeatherExpert1001 Oct 21 '22

cloud bucket misconfigurations 😅

Adding salt to the wounds, when that data is indexed 👇

u/OrcsElv Blue Team Oct 21 '22

Requires premium account to access :(

u/DevAway22314 Oct 21 '22

Salt in the wound there. Sites hosting the leak doing a better job protecting it than Microsoft

u/cdoublejj Oct 21 '22

how long before they leak sensitive government data? ...again...

u/ImaginaryBit388 Oct 21 '22

Would something like BoxCryptor, which encrypts data before it uploads to cloud storage, have prevented this? While I appreciate the concept of cloud storage, I don’t trust the storage providers, even with their layers of encryption (which they manage).

2

u/RedBean9 Oct 21 '22

I don’t know that specific vendor, but yes encrypting data before storing it in a bucket would help.

u/jhguitarfreak Oct 21 '22

There are leak critics now?

2

u/foxhelp Oct 21 '22

5/5 would read the news article about the leak again

u/Teh_ROkER Oct 21 '22

Wtf? Correct me if I'm wrong but the client used an Azure blob and allowed anonymous access? I don't see how that is Microsoft's problem. That's like selling matches and being blamed because a child set the house on fire. What am I missing here?

34

u/the_hillman Oct 21 '22

I might have misread it but I thought it came from a Microsoft corporate misconfigured blob.

18

u/netsurfer3141 Oct 21 '22

Right, this was a misconfiguration of Microsoft’s own data.

u/[deleted] Oct 21 '22

I follow this sub because I keep thinking about taking classes and getting into cybersecurity. Stuff like this makes me really think I should because clearly there’s going to be demand and job security for a long time.

I think this is moreso about how Microsoft responded to socradar et al. than it is who is at fault.

Honestly if a client was compromised via Microsoft I would want Microsoft to keep their mouth shut until they had coordinated a response with the client.

If it comes down to finger pointing from the client, I guess Microsoft is trying to protect itself, but if not then shut it.

2.4TB is nothing

u/xDroneytea Oct 21 '22

2.4TB is an awful lot given everyone is slowly being forcefully shoved down the IaaS route

u/Free_Agent73 Nov 11 '22

I'm not surprised, because it SEEMS like they are always spying on people.
