DDoS Thinking - AnonyViet - AnonyViet

There are many ways to crash a website

But there are many reasons why ddos won’t crash

Example 1: when I use dosnut1.4 running on my home machine ( 170k / month ) -> it crashed

but using it on google vps, it crashes Chinhphu.vn

=> reason: The higher the network speed, the stronger the request -> the sooner the database crashes. This tool will overwork the server’s MYSQL

Example 2: When I use Oneclickddos ( razer ) ddos in Sinhvienit crashes

=> even though there is a firewall [ click mới được vào website ] but for ddos, the ip will pass through the firewall, and a very special port [ 53 – dns thường ko có tường lữa ]

Here are two cases

1.close port 53

1.1 : ddos doesn’t crash => packet can’t be accessed

1.2 : ddos crash => network congestion [

2.open port 53 => 90% sẽ ddos sập

=> đối với các server dạng chứa firewall như thế này , bạn ko thể request điên cuồng vì nó sẽ chặn từ bên ngoài , nên ddos vào ip

Ví dụ 3 : vtc.vn là điễn hình với độ trâu bò code 1 nơi , data 1 nơi và hàng trăm máy chủ chạy song song [ nên ddos 1 tí chạy đc , 1 tí die , có người vào đc , có người ko ]

=> type directly into domain vtc.vn [ đến lượt máy chủ & data nào hoạt động thì nó sẽ tự lãnh hậu quả ]

This method will cause lag, not showing errors like the data can’t be processed in time, but usually a 503 error. Servers this big, they have to use a tool to flood the flood. [ dotnut 1.4 , HOIC ,…..]

Example 4: HVAonline runs on 2 servers, this guy is too busy, the other guy tips immediately, both has a soft firewall and a hard firewall, if the request is continuous you often see “….You have a read speed faster than the speed of light. shining …”

=> normal flood tools will be disabled.

It will see the same headers -> block

request twice -> block

ip query multiple -> block

url not from hvaonline.net [ khi bạn click từ 1 web khác vào ljnk forum ] -> do not allow access -> so the url from the tool will also be blocked

=> so you have to ddos directly to apache, random header, slow request, many ips will pass through Firewall

Summary . Depending on the server, we will respond differently

(although Sinhvienit is weaker than Chinhphu.vn, ddosnut1.4 is weaker than OneClickDdos)

But ddosnut can beat the official while it can’t beat svit

That is: If you are weak, hit there

If you don’t have to turn on the tool to ddos, then you can consider it strong, if you don’t, ddos will say it’s weak.

So are people – they lose to you in this
