Very big cyber incident playing out at Snowflake, who describe themselves as “AI Data Cloud”. They have a free trial where anybody can sign up and upload data… and they have.
Threat actors have been scraping customer data using a tool called rapeflake, for about a month.
The tl;dr of the Snowflake thing is mass scraping has been happening, but nobody noticed.. and they're pointing at customers for having poor credentials. It appears a lot of data has gone walkies from a bunch of orgs.
Snowflake is a big AI data company with a conference in the US next week, chances of that going ahead are interesting.

Snowflake admin users need to check their Snowflake environment, not sec departments check their on prem.
Five orgs have told me they are running incidents for Snowflake, where their data has been copied.
Snowflake: there is absolutely no cybersecurity incident.
Also Snowflake: Please run these commands and look for "threat activity" logins with the user agent "rapeflake" using this knowledge base article we haven't listed on our website.

Live Nation said its stolen database was hosted on Snowflake, a cloud storage and analytics company.
I've now confirmed 6 major orgs running Snowflake cyber incidents, so I've made a theme song about Snowflake's response.

For the record I don't think all the content is accurate - however Snowflake did have a security incident via their former employee, they have full IR stood up. They didn't follow their own best practices.
I also know multiple orgs who've had their full databases taken from Snowflake.
I wrote a blog on everything I know about the Snowflake situation https://doublepulsar.com/snowflake-at-central-of-worlds-largest-data-breach-939fc400912e
The Snowflake authentication setup is terrible.
MFA can’t be enabled org wide, each user has to manually log in and enable it. There’s no policy to block users without MFA. And it uses Duo MFA rather than your orgs MFA. (You can bring your own MFA with SAML).
Also all users log in via a Snowflake domain, so you can just pull creds from info stealer marketplaces or logs.
That’s why they’re being targeted as a platform.
Hudson Rock have put out a statement saying a legal threat from Snowflake caused them to remove their blog. https://www.linkedin.com/posts/hudson-rock_activity-7203433945919578113-RH05 HT @mattburgess
Another Snowflake customer breach: https://techcrunch.com/2024/06/07/snowflake-ticketmaster-lendingtree-customer-data-breach/
One thing I didn't know until recently is Snowflake has a massive fanbase, Apple and Amiga style - if you critique Snowflake in any way people flip tables. The comments on my blog are fun. I mean, the clue is in the product name, really.
IMHO it's fair to call out Snowflake's authentication isn't very good - it's the worst SaaS MFA solution I've seen as it has no top level, easy switch for org wide MFA enforcement.
Combined with putting all customers under *.snowflakecomputing.com sub domain is why their customers are getting owned - infostealers are just full of creds ready to go.
I gather Snowflake are discussing changes to fix, don't tell the fanboys (and yes, they're all dudes).
Mandiant have informed 165 organisations they may have had data exfiltration from their Snowflake hosted databases
https://cloud.google.com/blog/topics/threat-intelligence/unc5537-snowflake-data-theft-extortion/
Kinda interesting - Mandiant notified Snowflake that over 100 customers had data exfil issues, and Snowflake’s share price immediately began to tank in sells offs - before the incident was made public.
won a game of Call of Duty
hacked the world’s largest companies
used an infostealer
Can’t wait for these guys to have super secure Microsoft Recall, which is definitely encrypted from the user
Snowflake have told customers "We are also developing a plan to require our customers to implement advanced security controls, like multi-factor authentication (MFA) or network policies, especially for privileged Snowflake customer accounts."
Good! They also say the attack was "not caused by a vulnerability, misconfiguration, or breach of its product". Just happy little bad MFA.
Nice: "In a phone call this week, Jones (Snowflake CISO) told WIRED that Snowflake is working on giving its customers the ability to mandate that users of their accounts employ multifactor authentication going forward, “and then we’ll be looking in the future to [make the] default MFA,” he says."
This will be a great outcome for Snowflake customers and Snowflake itself. I know Snowflake got big mad at me for pointing it out, but that was a prime weakness in their MFA.

When Snowflake allows orgs to easily mandate MFA across their users, I plan to answer this forum post from 2019. https://community.snowflake.com/s/question/0D50Z00008ugjwISAQ/is-there-a-way-to-force-all-users-to-use-mfa
Cisco has a look across the wider infostealer problem, using Snowflake as a jumping off point: https://blog.talosintelligence.com/infostealer-landscape-facilitates-breaches/
I think SaaS providers who provide their own authentication have a responsibility to provide robust, *enforceable* MFA for their customers - so if an org wants all their users to require MFA, they can and it’s just an easy tick box.
Some SaaS providers aren’t doing this - - and it’s the reason infostealer logs are such a problem. Their angle is customer is solely responsible, but as a counterpoint: see how that is working out for Snowflake.
Snowflake have rolled out MFA changes:
- A new authentication policy that requires MFA for all users in a Snowflake account
- prompting for user-level MFA setup
- Snowflake Trust Center for monitoring adherence to MFA policies
This solves all the inherent product weaknesses from the prior setup, they did a good job.

@GossiTheDog The word Snowflake just gives me the mental image of someone taking this post out of context and turning it into a conspiracy theory surrounding either multi-factor authentication or, alternatively, grad school writing workshops.
