Uh-Oh Cyber-News: Infect a Friend, Rebooting Boeings, No-Authentication Holes, and More.

Hi folks!

Herewith, the next installment in my ‘Uh-oh Cyber-News’ column – the one in which I keep you up to date with all that’s scarily fragile and frailly scary in the digital world.

Since the last ‘Uh-oh’ a lot has piled up that really needs bringing to your attention. Yep, the flow of ‘Uh-ohs’ has indeed turned from mere mountain-stream trickle to full-on Niagara levels. And that flow just keeps on getting faster and faster…

As a veteran of cyber-defense, I can tell you that in times past cataclysms of a planetary scale were discussed for maybe half a year. While now the stream of messages is like salmon in spawning season: overload! So many they’re hardly worth mentioning as they’re already yesterday’s news before you can say ‘digital over-DDoSe’. “I heard how they hacked Mega-Corporation X the other day and stole everything; even the boss’s hamster was whisked away by a drone!”…

Anyway, since the stream of consciousness cyber-scandals is rapidly on the up and up, accordingly, the number of such scandals I’ll be writing about has also gone up. In the past there were three of four per blogpost. Today: seven!

A Brief History of DDoS Attacks.

And so it’s come to pass: the abbreviation ‘DDoS‘ has entered the lexicon to such an extent that it often doesn’t get written out in full these days in the general interest newspapers. Well, some actually may still not know what it stands for, but everyone and their dog does know that a DDoS is very bad thing for a certain large target, with something very important suddenly not working, with employees twiddling their thumbs as the network’s down, and with their tech-support’s telephones requiring an ice bath as they’re so hot from ringing – and disgruntled clients swearing down them all the time. What’s more, everyone and their cat also knows that normally a DDoS attack gets carried out by unknown, mysterious – and just plain bad – cyber-enemies.

DDoS attacks have evolved very quickly, as you’ll find out reading this blogpost. They’ve grown much nastier and become a lot more technically advanced; from time to time the adopt utterly unusual attack methods; they go after fresh new targets; and break new world records in being the biggest and baddest DDoS’s ever. But, then, the world in which DDoS find themselves in has evolved very quickly too. Everything and the kitchen sink is online: the number of assorted ‘smart’ [sic] devices connected to the net now far outstrips the number of good old desktop and laptop computers.

The result of these two evolutions running in parallel – of DDoS’s themselves plus the digital landscape in which they dwell – has brought us equally evolved headlines: botnets made up of IP cameras and home Wi-Fi routers breaking DDoS records on size (Mirai), and massive DDoS attacks on Russian banks.

If, earlier, botnets were made up of zombie PCs, soon they’ll be made up of zombie refrigerators, vacuum cleaners, tumble dryers and coffee machines.

The Internet of Harmful Things.

In the early 2000s I’d get up on stage and prophesize about the cyber-landscape of the future, much as I still do today. Back then I warned that, one day, your fridge will send spam to your microwave, and together they’d DDoS the coffeemaker. No, really.

The audience would raise eyebrows, chuckle, clap, and sometimes follow up with an article on such ‘mad professor’-type utterances. But overall my ‘Cassandra-ism’ was taken as little more than a joke, since the more pressing cyberthreats of the times were deemed worth worrying about more. So much for the ‘mad professor’…

…Just open today’s papers.

Any house these days – no matter how old – can have plenty of ‘smart’ devices in it. Some have just a few (phones, TVs…), others have loads – including IP-cameras, refrigerators, microwave ovens, coffee makers, thermostats, irons, washing machines, tumble dryers, fitness bracelets, and more. Some houses are even being designed these days with smart devices already included in the specs. And all these smart devices connect to the house’s Wi-Fi to help make up the gigantic, autonomous – and very vulnerable – Internet of Things, whose size already outweighs the Traditional Internet which we’ve known so well since the early 90s.

Connecting everything and the kitchen sink to the Internet is done for a reason, of course. Being able to control all your electronic household kit remotely via your smartphone can be convenient (to some folks:). It’s also rather trendy. However, just how this Internet of Things has developed has meant my Cassandra-ism has become a reality.

Uh-oh Cyber-News: The Future’s Arrived, and Malware Back from the Dead.

As always for this ‘column‘, I’ll be giving you a round-up of some of the most eek recent items of cybersecurity news, which might not have made the headlines but which are no less eek for that. And as usual, it’s all mostly bad news. There are still a few reasons to be optimistic though – but only a few. Eek!

Uh-oh Cyber-News Item No. 1: The Future’s Arrived.

Many authors like to fantasize about how things will be in the future. Often, science fiction writers come up with deep philosophical reflections upon man and his place in the Universe. There’s Russia’s Strugatsky brothers, there’s Philip K. Dick, and there’s Arthur C. Clarke (plus his ‘translator’ to the silver screen Stanley Kubrick), for example. And very often such deep philosophical reflection is rather bleak and scary.

Other times, the reflection is a little less deep and philosophical, but no less likely to one day lead to reality – in fact, oftentimes more so. This is where I make appearances!…

So. Back in the first decade of this century, during my presentations your humble servant liked to tell fun ‘scare’ stories about what could happen in the future. Example: a coffeemaker launches a DDoS attack on the fridge, while the microwave works out the factory PINs of the juicer so it can then show text-adverts on its digital display.

Fast forward less than a decade and such ‘sci-fi’ is coming true…

Our antivirus formula.

Every system is based on a unique algorithm; without the algorithm there’s no system. It doesn’t really matter what kind of algorithm the system follows – linear, hierarchical, determined, stochastic or whatever. What’s important is that to reach the best result the system needs to follow certain rules.

We’re often asked about our products‘ algorithms – especially how they help us detect future threats better than the competition.

Well, for obvious reasons I can’t divulge the details of our magic formulae; however, what I will be doing in this tech-post (perhaps the techiest post on this blog ever) is open ajar the door to our technological kitchen – to give you a glimpse of what goes on inside. And if you still want more info, please fire away with your questions in the comments, below.

Beyond good and evil?

A few days ago Microsoft announced a large scale raid on the dynamic DNS service No-IP, as a result of which 22 of its domains were seized. The guys in Redmond said there were very good reasons for this: No-IP hosts all kinds of unpleasant malware; No-IP is a breeding ground of cybercriminals; No-IP is an epicenter for targeted attacks; and No-IP never agrees to working with anyone else on trying to root out all the badness.

Like in most conflicts, the sides have exchanged the contradictory volleys of announcements in the eternal tradition of ‘it’s his fault – no she started it’.

In particular, No-IP has said it’s a real goody-two-shoes and always willing to cooperate in eliminating sources of cyberattacks, while its clients are most displeased with the raid and consider it an illegal attack on legal business – since it’s possible to find malware practically anywhere, so interrupting services through a court is simply not on.

Is it legal to shut down a service because of #malware found?… When it can be found everywhere?…Tweet

In the meantime, the result of the raid has been rather far-reaching: more than four million sites were pulled, including both malicious and harmless ones – affecting 1.8 million users. Microsoft is trying to sieve the wheat from the chaff and get the clean sites back up and running; however, many users are still complaining about ongoing disruption.

To work out who’s to blame is a thankless and probably hopeless task. I’ll leave the journalistic investigations to… the journalists. Instead, here let me give you some food for thought: dry, raw facts and figures – so maybe/hopefully you’ll be able to come to your own conclusions about the legality and ethicality of MS’s actions, based on those facts and figures…

1)      Shutting down 22 No-IP domains affected the operations of around 25% of the targeted attacks that we keep track of here at KL. That’s thousands of spy and cybercriminal operations ongoing for the last three years. Approximately a quarter of those have at least one command and control center (C&C) with this host. For example, hacker groups like the Syrian Electronic Army and Gaza Team use only No-IP, while Turla uses it for 90% of its hosts.

2)      We can confirm that out of all large providers the No-IP dynamic DNS was the most unwilling to cooperate. For example, they ignored all our emails about a botnet sinkhole.

3)      Our analysis of current malware shows that No-IP is often used by the cyberswine for botnet control centers. A simple search via the Virustotal scanning engine confirms this fact with a cold hard figure: a total of 4.5 million unique malware samples sprout from No-IP.

4)      However, the latest numbers from our security cloud (KSN) show something not quite so cut and dry. Here’s a table showing detections of cyberattacks from dozens of the largest dynamic DNS services:

Service % of malicious hosts Number of detections (in a week)
000webhost.com 89.47% 18,163
changeip.com 39.47% 89,742
dnsdynamic.org 37.04% 756
sitelutions.com 36.84% 199
no-ip.com 27.50% 29,382
dtdns.com 17.65% 14
dyn.com 11.51% 2321
smartdots.com 0.00% 0
oray.com 0.00% 0
dnserver.com 0.00% 0

So – No-IP isn’t leading in the number of detections, even though they’re still really high compared to most.

Here’s some more info for comparison: the % of malware hosts in the .com zone makes up 0.03% of the total; in the .ru zone – 0.39%; but in No-IP the figure’s 27.5%!

And now for other figures that add a bit of a different perspective: in one week, malware domains on No-IP generated around 30,000 detections, while in the same week on one of the most malicious domains in the .com zone, the figure was 429,000 – almost 14 times higher. Also: the tenth most infected domain in the .ru zone generated 146,000 detections – that is, about the same as the first ten providers of dynamic DNS mentioned above put together!

To summarize…

On the one hand, blocking popular services that are used by thousands – if not millions – of typical users: it ain’t right. On the other hand, closing spawning grounds for malware is right – and noble.

The takedown of No-IP domains. Was it right or wrong? Ambiguity with a big ATweet

But then mathematics takes on the role of devil’s advocate, and proves:

Quantitatively, closing all the domains of No-IP is no more effective in combatting the distribution of malware than closing one single top malware domain in one of the popular zones, i.e., .com, .net, or even .ru. Simpler put, even if you were to shut down all providers of dynamic DNS – the Internet still wouldn’t become ‘cleaner’ enough to notice the difference.

So there you have it – ambiguity with a big A. 

It leaves anyone in their right and honest-with-themselves mind to admit things are far from black and white here, and as regards the right and wrong, or good and bad, or Nietzsche’s thing – who can tell?

Still, another thought comes to mind at some point while reflecting on all this…

It’s further evidence that as soon as the quantity of piracy or degree of criminality gets above a certain threshold, the ‘powers that be’ get involved all of a sudden and start closing services, ignoring any notions of Internet freedom or freedom to do business. It’s just the way things are, a rule of life of human society: If it stinks, sooner or later it’ll get cleaned up.

The list of blocked services is already rather long: Napster, KaZaA, eMule, Pirate Bay and so on. Now No-IP‘s been added to the list.

Who’s next?
