How the StarHub DDOS (possibly) happened

starhub-dns-attackCustomers of Singaporean ISP StarHub, suffered two major disruptions to their service over the past week, in what the telco said was a result of a “intentional and likely malicious distributed denial-of-service (DDoS) attacks”.

Oh the humanity!!

In what appears to be a copycat of the Dyn attack we saw (at roughly the same time), the attack signals the first local salvo in the war of IOT devices. But is it really that serious?

If you’re wondering what the hell happened, let’s walk this through step-by-step, from the attackers perspective.

Internet of shitty things!

b66b95478fBrian Krebs is the most reputable name in CyberSecurity reporting, his krebsonsecurity website is the best source of ‘real’ journalism on the subject.

But reputation works both ways, the same thing that makes him popular in some circles, makes him unpopular in other. He’s had criminal hackers send him heroin in the mail and even have SWAT teams descend on his home with guns all blazing (in a phenomenon called swatting!). Reporting and exposing underground cyber-criminals comes at a price, you don’t piss of darknet crime lords without taking a few hits along the way.

The problem though is when those ‘few’ hits, turn into a hurricane of web traffic aimed at your server, because that’s exactly what descended on Krebs’ server late last week, when krebsonsecurity was hit by an epic DDOS attack

DDOS is an acronym for Distributed-Denial-of-Service, which basically means forcing so much web traffic to a single website that it eventually collapses–making it unable to provide services to the ‘real’ visitors of the site. All websites run on servers with finite capacity, DDOS attacks are about sending enough traffic to those servers that they eventually exceed that capacity.

But this DDOS was different, and krebsonsecurity will go down in history as the Hiroshima of this type of DDOS. But nuclear weapons only had Hiroshima and Nagasaki, krebsonsecurity will be the first in a Looooong line of DDOS attacks of this scale.

So what makes this attack so different as to merit it’s own class? Well 3 things.

All you eggs in one basket

Is it wise to use an online password manager? After all, putting your passwords on the cloud seems like a really dumb idea.

But I use password manager because while storing stuff on the cloud may present risk, it’s far riskier and dumber to re-use passwords.

Why you need a password manager?

Despite the sexiness of zero-day exploits and hardcore state-sponsored hacking groups we see on the news, the number one way the average person gets hacked is through password compromise (boring!). That’s when hackers guess, or somehow figure out your passsword, and then use it to access the various online services you subscribe to.

Most people downplay the risk of this happening, ebcause they think they’re not rich enough, or famous enough to be the target of hackers. But in an era, where hacks compromise millions of accounts, and hackers can automate exploits to run on cheap cloud servers from Amazon–you’d be surprise what hackers consider a worthwhile target.

But how do hackers get your password?

On occassion they actually guess it, ala ‘the fappenning’, but more commonly they get your passwords by hacking other services. Shockingly, sometimes the easiest way to get your Google password is to hack dodgy forums, and insecure chat rooms that litter the internet.
