Hackers claim responsibility for Twitter outage


A hacker group has claimed credit for outages at Twitter after the company said it was affected by a “cascaded bug” which hit the wildly popular website.

“We just #TangoDown’d http://twitter.com for 40 minutes worldwide!” said a tweet on Thursday from the group called UGNazi, which has been linked to attacks on US government websites.

The term “tango down” is used in the hacker community to refer to a so-called denial of service attack which can shut down a website.

The company first acknowledged “issues accessing Twitter,” and said its “engineers are currently working to resolve the issue.”

Around an hour later, Twitter said: “The issue has been resolved and all services are currently operational.”

But after the problems resurfaced, Twitter said: “Today’s outage is due to a cascaded bug in one of our infrastructure components.”

It followed up by saying, “A cascaded bug has an effect that isn’t confined to a particular software element; its effect ‘cascades’ into other elements as well.”

The company made no mention of an attack, and the reference to a “cascaded bug” left some experts confused.

A cascaded bug “probably means a glitch that caused one server to fail in an odd way, or send an odd message, that caused a neighboring server to fail, ad nauseum,” said Michael Hicks, director of the University of Maryland Cybersecurity Center.

“Very quickly, a bunch of systems are down.”

Hicks said the claim of a “denial of service” or DOS attack “usually consists of a computer, or many computers, sending tons of traffic at a service. But it could also be due to smartly chosen traffic that cases a bug to manifest that results in the bad behavior we saw, bringing down parts of the system.”
