Mirai botnet was used to power a massive DDoS attack against Liberia causing the Internet outage in the entire country. The financial repercussions of the attack on the country are devastating. Mirai was first spotted this summer by the security expert MalwareMustDie, now media reported the use of the dreaded botnet against Liberia with financially devastating results. The attacks are extremely worrying because they suggest a Mirai operator who has enough capacity to seriously impact systems in a nation state. The way to stop it, are, either we push the effort to arrest skiddes who related to this botnet, and more strict in rule/policy for DDoS abuses.”]
