Kênh youtube bị ăn bom nổ chậm rồi đây......
One does not simply DDoS Google in order to silence a YouTube channel; no one has that kind of bandwidth. Instead, what the attacker did was to spam the channel with “dislikes,” a way to try and impact the revenue stream of the channel operator by manipulating YouTube’s view recommendation system.
By checking his channel statistics, Dave noticed (like other channel owners who had criticized the same product) that the overwhelming majority of dislikes were coming from Vietnam, all at once in massive spikes that did not correlate with an increase in the number of views to the videos being disliked. Anyone (hopefully YouTube’s abuse team) can see that the data points to large-scale vote manipulation. So why Vietnam? Dave speculated that it might be because Vietnam is a low-wage economy, where it is possible for residents to make an actual living doing menial tasks on the Internet for a meager income, making things like vote spamming a profitable business in those areas of the world. This is certainly a possibility, and we’ve seen reports of such operations in existence for many years in other countries.
However, there's another possibility – someone is using Vietnamese IP addresses as a proxy to hide their nefarious activity coming from a single machine, preloaded with thousands of either fake or stolen YouTube accounts. This would certainly be even more economical than paying workers to click “dislike” buttons, as it could be operated by a single individual with the help of some specialized software, and could be done more quickly (which could manifest itself as the huge temporal “dislike” spikes Dave’s channel statistics showed). Now, most operations of this sort would simply use a botnet or a network of existing open proxy servers around the world. But there is something peculiar about Vietnam when it comes to Internet infrastructure that may lend itself to this theory.
