It's not necessarily 'deleted', these Script Kitties just replaced some data with more valuable stuff. You can never have enough meows! But seriously, these guys are doing us a favour. You can bet the affected companies will not expose customer data again.

> You can bet the affected companies will not expose customer data again. I hope so, but I seriously doubt that. Having open databases is extreme incompetency.

Didn't Equifax have open customer data back when that attack happened?

If the databases in question (Elastic, MongoDB, others) make it too easy to set up unsecured access, possibly because they default to an unsecured state on installation, then some good may come of this: The reputation hit to the database vendors should encourage them to mend their ways. If that happens, then the attack can arguably be justified despite the damage — consider all the future database installations which…

It's also easy to get bitten by Docker. You can secure your server with iptables/ufw only to discover that docker happily punches through your firewall and you need to filter on the DOCKER-USER chain - and even that was broken: https://unrouted.io/2017/08/15/docker-firewall/ https://github.com/docker/for-linux/issues/690

I can't believe people are victim blaming the db admins for not knowing about vulnerability. What good comes of destroying the db instead of talking about the vulnerability to the open source projects? Coincidentally shodan; that I've never heard of.

You don't need to be a carpenter to know that you should install a lock on the front door of your house. How does anyone get to the point of standing up a production db and is allowing writes from unauthenticated connections?

I am pretty salty since as a sysadmin, I have been getting 'just pipe it to su bash' and 'i need allow any any' and 'bro I need chmod 777 on this directory and all its children' and 'bro this service account has to be a domain admin' from developers my entire professional career. Everything that there is to say has already been said and I am not really sure what to do about it. Nobody is out there peddling these cool fixes as truth and yet they seem to have a cult all the same.

What can we do to make this common knowledge? This needs to be on the same level as washing your hands and not accepting candy from strangers, yet every week we see a new data breach that boils down to 'somebody used the rights as they were designed'.

Why is the person doing the deleting so low, relatively speaking, in your ranking of people's responsibility for them doing the deleting? Also, do you think that this person or persons would refrain from deleting the data if they had the opportunity, but it qualified as a "good idea" to keep online? I.e. they might review, say, medical records, spend some time thinking to themselves whether it was 'necessary' to be o…

For me, it's because the odds of this person showing up quickly approach 1 as time approaches infinity, and that person's effect would be nil if it weren't for necessary causes 1) through 19). Blaming the person that hacked you is like blaming the individual rock that sinks your boat when you navigate too close to a rocky shore. The rock may have done 100% of the damage to your boat, but if it hadn't been that rock,…

Are you saying rocks have intent when they sink your boat?

That's just victim blaming. The same logic applies to every crime: "lock your doors if you don't want your TV to be stolen!". It also works at any level of security: "Lock your doors and hire guards if you don't want clever thieves breaking a window..." But if you require everyone to take adequate measures to physically secure their houses, you don't even need laws and morality! And while this may provide the sort of…

You're not thinking of the right victim. You're considering the organizations who compiled the databases in question. If the databases are composed entirely of their own information that they created themselves, then sure they've suffered a loss. In most cases, however, these databases include privacy-sensitive personal information about the customers of the organization. Those customers have been victims of bad security practices ever since MongoDb was first installed, and this "meow" hack has ended their victimization.

Why not just rename all the tables or something? That's enough to get the developer's attention without being so destructive.

My website once started failing because someone had connected to redis and set a password on it. That was the day I found out the redis docker container accepts everything that can connect to it unauthenticated by default.

It's a problem for the vendors, not the banks. They get hit with chargebacks for fraud that's no fault of their own, hurting the whole ecosystem of vendors and their customers. https://www.thestreet.com/personal-finance/credit-cards/cred...

The problem could be easily solved by Visa/MC/Discover/Amex implementing chip and pin, or at least 2FA SMS authorization. Bestbuy.com has it working somehow.

These people can't configure a firewall. How are they going to implement payments in the secure fashion you suggest?

Is there an inexpensive service out there that does “mock” attacks if you give it a bunch of host names and ports? I know it’s something you could create yourself but would be nice to have a third party try to connect to your databases and immediately alert you if it was able to gain access. Would especially be useful if you were tinkering with firewall/security settings and accidentally opened something up.

Shodan Monitor will do it and if you're only keeping track of https://www.shodan.io/store/member ). You just provide an IP/ network/ domain and we'll notify you if anything changes or becomes vulnerable. It's basically Google Alerts but for network ports: https://monitor.shodan.io Disclaimer: I'm the founder of Shodan.

That's a cool product, didn't realise Shodan did that

This reminds me of "crackit"[0] from a few years ago with Redis. A lot of folks kept their Redis server bound to 0.0.0.0 with no firewall or published port 6379 by "accident" with Docker and by default Redis uses no password. It was a lot worse than meow because with some Redis configuration magic anyone could inject their own SSH keys onto the server. This article says Redis is affected but I would be curious to see…

This happened to me. Was just getting started with docker and got everything working and a few months later someone had set a password on my redis database. Who knows what else happened before that.

Ended up deleting the server.

In construction and landscaping work those companies are usually licensed, bonded and insured. If they fuck up the work there's obvious financial recourse. Also, the measure of them fucking up is generally a lot clearer for physical labor and for mom and pop businesses, getting construction work inspected by a 3rd party is usually more straightforward and cheaper. In software, financial recourse generally means you h…

I don't how it is in the US, but in my country an audit that would reveal such an obvious lack of security costs no more than the equivalent of a single minimum salary - usually much less. On top of that several companies that offer such services are widely known because their media presence is mostly articles about vulnerabilities in routers, phones, operating systems etc. I hail from a post-communist country so I a…
