German security experts have suggested internet outages that have hit hundreds of thousands of Deutsche Telekom customers in Germany were part of a worldwide attempt to hijack routing devices.

“The BSI considers this outage to be part of a worldwide attack on selected remote management interfaces of DSL routers,” the government agency said on its website.

Deutsche Telekom said the issues seemed to be connected to an attempt to make a number of customers’ routers part of the Mirai botnet.

a Mirai botnet perturbed Liberia’s internet connectivity

Liberia is connected to internet via only one undersea cable (part of ACE - African Coast to Europe) of 5.12 Tbps, shared between all 23 countries connected via ACE.

Mirai has been targeting IP addresses of Lonestarcell MTN, a telecom operators managing the Liberian ACE leg, flooding the pipe with 500 Gbps and thereby impacting Liberia’s internet several times. (well, the 6% of the country that actually has internet access).
Lonestarcell MTN is one of the 4 telecom operators

Many media, including BBC, PC World, The Guardian, Forbes, IBtimes, Quartz, Mashable, The Register, inaccurately reported that Liberia was totally cut off.

“Both our ACE submarine cable monitoring systems and servers hosted (locally) in LIXP (Liberia Internet Exchange Point) show no downtime in the last 3 weeks,” [the general manager of Cable Consortium of Liberia] said. “While it is likely that a local operator might have experienced a brief outage, we have no knowledge of a national Internet outage and there are no data to substantial that.”

Massive Internet Outage Could Be a Sign of Things to Come

Schneier pointed out last month that a new wave of attacks also seems to be more investigative than previous DDoS assaults. Many of the attacks appear to be testing servers rather than taking them offline, by gradually increasing barrages of requests at one part of the server to see what it can withstand, then moving on to another, and another. Schneier warned that “someone is learning how to take down the Internet.”

It wasn’t a cut cable and it wasn’t the Syrian government deliberately blocking access either...
