HiTech Service Successfully Confronted Powerful DDoS Attack

This is a story of a highly successful and quick fight with DDoS-ers.

HiTech Service Successfully Confronted Powerful DDoS Attack
New York, NY, June 16, 2015 --( Pre-history

One day a system administrator got an extraordinary e-mail.

Someone threatened the company to start powerful DDoS attack on the one of the company's client's site. They wanted money and gave the company a day.

They are is one of HiTech Service's respectable clino actually ents having vast IT infrastructure.

They wanted 25 Bitcoins to a predefine account.

Problem Evaluation

Next day the DDoS-ing started as they promised.

The attackers used IP addresses as targets for UDP amplification DDoS attack against customer's uplinks, so we used BGP blackhole communities to discard traffic at Edge routers of upstream Tier1 ISPs.

Taking into account difference between average daily traffic and traffic when DDoS-ing, they were getting approximately 100 GBit/sec load on the network. Traffic dump shown ~120.000 infected nodes that were producing the ddos attack itself. This impresses a lot and shows that an average DDoS-er has such considerable resource in hand.

Problem Resolution

HiTech beat the attack in 10 minutes. The attackers had an IP address as a target for DDoS-ng, so they used BGP protocol to redirect attackers to nowhere:

- They captured all traffic hitting router uplinks during attack;
- They did BGP blackhole for attacked IP addresses;
- They started website on other Uplinks and forwarded traffic via Cloudflare to protect customer infrastructure from UDP flood attack.

That's all. If you have the same troubles with attackers, call HiTech. They help.
