The popular coding website Github suffered a large-scale distributed denial of service (DDoS) attack that lasted more than 24 hours starting from Thursday night. The attack exploited the redirection of users who were connecting to many other websites on the Internet. The attackers injected malicious JavaScript code into the pages of those websites that was responsible for the hijacking of their visitors to Github. Baidu, the search engine, has denied any responsibility for the attack. Experts speculate that the attackers are linked to the Chinese Government that used the browsers of unaware users to hit a website not aligned to Beijing.”]
