Slack security makes ‘big data’ too easy to steal

- Juha Saarinen comment

Who hasn’t come across the “big data” buzz term yet? Everyone’s doing it: Collecting lots of informatio­n via sensors, public data sets going back years, all manners of sources.

It can be anything, literally, that computer scientists use massive IT systems to devour and pick through for interestin­g patterns.

That big data has to go somewhere, and be accessible from the internet to be of use to researcher­s and others, of course.

Did you wonder if those big databases storing huge amounts of informatio­n were safe and secure? Wonder no more: They’re not.

When I say they’re not secure, I mean the databases are left wide-open for anyone to do whatever they like with.

This year has seen a rash of attacks on internetco­nnected databases containing huge amounts of informatio­n. Around 40,000 databases have been wiped around the world, with hundreds of terabytes (one terabyte is a thousand gigabytes) gone. The tally’s probably even higher now, as attackers have scanned the internet to find open databases and there are hundreds of thousands of those around.

It’s no clever hacking attempt, just taking advantage of the fact that the databases have been installed with zero considerat­ion for security like having access controls, and not allowing every person and their dog in, with full administra­tor rights.

Most of the attacks have been blackmail attempts.

“Your data’s deleted, pay 1 bitcoin to get it back.”

Except you’re not going to get it back.

There’s no evidence that the attackers spent the probably considerab­le amount of time and had the costly bandwidth and storage capacity required to back up the data before deleting it.

Other deletions have been simple vandalism, or maybe a misguided attempt at encouragin­g database administra­tors that they need to secure their systems.

Few organisati­ons have been able to get their data back, and it seems nine out of 10 operators do not back up the informatio­n in the databases, security researcher­s noted.

The vulnerable database servers are found across a range of industries and scientific organisati­ons.

Medical research institutio­ns, marketing firms, schools and academia, financial and insurance companies, manufactur­ers and software developers are just some that have been hit.

As many of the victims ran the databases on their production systems, it’s a safe bet to assume that quite a bit of important informatio­n has been lost, maybe forever.

That’s bad enough, but if the databases were left open to anyone on the internet, was some sensitive personally identifiab­le data siphoned off quietly by bad people who should not have access to it?

I don’t think anyone would be surprised if that has happened, too, and the privacy implicatio­ns are scary.

From the above we can learn that data, big or small, is popular with all sorts of organisati­ons and people who have no idea how to secure their systems and that that is a global problem.

It’s cool to be a data driven organisati­on sifting through masses of info for insights, but keep it safe please.

And back up often because the internet will punish the careless sooner rather than later.
