Don't use this script

It's absolute crap. It won't do anything and you will get caught. More info here

I didn’t see anything about the script on that site.. but I appreciate your confrontation.. this code it is shit @Eik0 but it does do something rather than nothing.. this tool is for public use what do you expect it to be over powering? If you guessed that you are wrong.. it was used on sites during a protest on Minneapolis more than one machine had this installed.. have you done any analysis yourself about the script?

While I think it's a good idea in theory, you're actually putting people at risk. It certainly works on large networks, but it's pretty useless and dangerous on personal computers.
You can find details on the link I posted, under "Analysis of OP-Minneapolis DDoS tool", then the pdf file.
It's a very detailed analysis of your code but to summarize:
• your scrap function is done without proxy, so the website is getting tons of requests from the attacker ip
• you're taking public proxy lists, so there is potential for X-Forwarded-For IP address
• you're running the attack on a single thread which is.. very inneficient (max 50mbps according to the paper)
• please don't put all your user agents at the beginning of the same file, and do proper naming of your variables T_T

But once again I get the "public" thing and I like this kind of initiative, but please before releasing and claiming it's safe, think about all the potential flaws
