The Spamhaus Project, an international nonprofit organisation that tracks spam and cyber-related threats, ironically faced a large DDoS attack in 2013 that managed to slow down the entire internet , with parts shutting down for hours. The attack generated a stream of over 300 billion bits of data per second , which was such a large quantity that it even knocked Cloudflare , a company specializing in helping organisations stay online amid such attacks offline. The attacks were the work of Stophaus , a group of individuals that had grievances against Spamhaus for adding their cybercrime enterprises and spam operations to a blocklist . The record-breaking attacks were a lesson on how DDoS attacks can affect a company's websites, mail servers and, ultimately, its entire infrastructure. #hack #hacker #cybersecurity #1337
