Code repository Github is still battling against a DDoS attack that began on Thursday that the company is calling the largest DDoS attack in its history. According to several reports, the attack appears to originate from China.
According to a blog post by GitHub on Friday: “the attack began around 2AM UTC on Thursday, March 26, and involves a wide combination of attack vectors. These include every vector we’ve seen in previous attacks as well as some sophisticated new techniques that use the web browsers of unsuspecting, uninvolved people to flood github.com with high levels of traffic.”
According to a report on Monday by Ars Technica, the DDoS is specifically targeting two GitHub projects that are anti-censorship in China: GreatFire and a Chinese language version of the New York Times.
GitHub said that based on reports it has received the attack is intended to remove a specific class of content. As of 11:18 am, Github said that all systems are reporting at 100 percent.
GitHub kept users updated on its DDoS mitigation efforts and progress via its status Twitter account. An update around seven hours ago said that the DDoS attack had evolved and it is working to mitigate.
Baidu has denied the attack, assuring that it has “ruled out the possibility of security problems or hacker attacks on [its] own products,” the company said in a statement.
The DDos attack against GitHub comes after GreatFire.org mirror sites were hit by a sustained DDoS attack following an article published by the Wall Street Journal that described how anti-censorship groups use US cloud computing services to circumvent blocking by Chinese authorities. The attack was delivering up to 2.6 billion requests per hour at its peak.
