Massive cyberattack grinds Liberia's internet to a halt Massive cyber-attack grinds Liberia's internet to a halt
(about 1 hour later)
The entire internet infrastructure of the African nation of Liberia has been brought to a grinding halt after it was targeted by hackers using the same weapon that caused the largest cyberattack in history just two weeks ago. The entire internet infrastructure of the African nation of Liberia has been brought to a grinding halt after it was targeted by hackers using the same weapon that caused the largest cyber-attack in history just two weeks ago.
The attack was a distributed denial of service or DDoS, in which a network of infected computers – a botnet – is directed to bombard its target with traffic, overloading its servers.

The weapon used in the October attack, the Mirai botnet, was particularly effective because it harnessed infected, internet-connected devices such as DVR players and digital cameras.The weapon used in the October attack, the Mirai botnet, was particularly effective because it harnessed infected, internet-connected devices such as DVR players and digital cameras.
Now the same weapon has been used over the past seven days in continued attacks on the west African nation of Liberia, according to Kevin Beaumont, a security expert who has been closely monitoring attacks using Mirai botnets.Now the same weapon has been used over the past seven days in continued attacks on the west African nation of Liberia, according to Kevin Beaumont, a security expert who has been closely monitoring attacks using Mirai botnets.
“We’re seeing attacks over 600gbps [gigabytes per second] aimed at two companies which co-own the only fibre going into [Liberia],” Beaumont told the Guardian, adding that during the attacks websites inside the country are rendered unavailable outside as well. “The recent attacks ... are huge in volume – among the most amount of traffic internet has seen.”“We’re seeing attacks over 600gbps [gigabytes per second] aimed at two companies which co-own the only fibre going into [Liberia],” Beaumont told the Guardian, adding that during the attacks websites inside the country are rendered unavailable outside as well. “The recent attacks ... are huge in volume – among the most amount of traffic internet has seen.”
Zdnet reported that infrastructure providers had said the attacks were over 500gbps in size – not as large as the 1,100gbps (1.1 terabytes per second) attack in October, but still among the largest DDoS attacks ever.Zdnet reported that infrastructure providers had said the attacks were over 500gbps in size – not as large as the 1,100gbps (1.1 terabytes per second) attack in October, but still among the largest DDoS attacks ever.
The previous target was Dyn, a company that controls a large number of domain name service infrastructure that acts as a switchboard for internet traffic, through which the attack brought down major internet services across Europe and the US including Twitter, Netflix and Spotify.The previous target was Dyn, a company that controls a large number of domain name service infrastructure that acts as a switchboard for internet traffic, through which the attack brought down major internet services across Europe and the US including Twitter, Netflix and Spotify.
Experts told the Guardian that the Dyn attack may have been by far the largest of its kind. Mirai is also open-source, meaning anyone with the requisite know-how can use it.

The particular Mirai botnet that is attacking Liberia, officially named Botnet 14 14, has a Twitter account – @MiraiAttacks – which tweeted threateningly at Beaumont after he looked into the attacks, leading him to dub this particular Mirai botnet “Shadows Kill”.The particular Mirai botnet that is attacking Liberia, officially named Botnet 14 14, has a Twitter account – @MiraiAttacks – which tweeted threateningly at Beaumont after he looked into the attacks, leading him to dub this particular Mirai botnet “Shadows Kill”.
It is not known who is wielding the Mirai botnet against Liberia, or whether it is a state actor or independent hackers. In a blog post, Beaumont said: “The attacks are extremely worrying because they suggest a Mirai operator who has enough capacity to seriously impact systems in a nation state.” It is not known who is wielding the Mirai botnet against Liberia, or whether it is a state actor or independent hackers.
