We (
https://coinut.com) were just attacked by a team called DD4BC using DDoS.
DD4BC Team <
dd4bc@safe-mail.net>:
Hello,
Your site is extremely vulnerable to DDoS attacks.
I want to offer you info how to properly setup your protection, so that you can't be ddosed.
If you want info on fixing it, pay me 1 BTC to 13adm65yzzre7fLKSFZayQ8dYyxgXaVyMU
Xinxi Wang:
Thanks. Yes, I know this. It's currently a little vulnerable to DDoS attacks. But we just cannot afford the money to fix it at this moment. I will definitely contact you when we are ready.
Then they just sent millions of requests. And it's difficult for me to open the site.Xinxi Wang:
Man, you just selected the wrong target. Maybe you should try this after a few months.
DD4BC Team:
OK, contact me within a few months and I will stop the attack. Smiley
CloudFlare will not help.
And one more thing: Price is 1 BTC today. Tomorrow it will increase to 2 BTC and will keep increasing for every day of delay.
Xinxi Wang:
Man, I am a computer science PhD student, and I don't have so much money.
DD4BC Team:
Good for you. I'm not sure how is your formal education going to help in this situation, but...good luck.
Xinxi Wang:
I also think so.
Xinxi Wang:
I am wondering how much it costs for you to send so much traffic?
DD4BC Team:
I'm using botnet which I paid 0 USD, so my cost is 0 USD.
Xinxi Wang:
Pretty cool.
BTW, I simply blacklisted their IP addresses. The site is now working although they are still attacking. It's a bit slower though. Anyone has good methods for this kind of attacks?
