DDoS Attacking is not Hacking – Understanding DDoS Attacks
In computing, a denial-of-service attack (DoS attack) is a cyber-attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. It is analogous to a group of people crowding the entry door or gate to a shop or business, and not letting legitimate parties enter into the shop or business, disrupting normal operations.
Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Motives of revenge, blackmail or activism can be behind attacks. — Wikipedia Reference
After the huge DDoS attack on DYNdns earlier this week marking one of the largest DDoS attacks in history I decided to make a video to help educate the public on why the media is always getting it wrong when they refer to DDoS attackers as hackers and also what we can do to stop these little script kiddies with nothing better to do from creating large bot networks and attacking services.
▼ Internet of Things devices ▼
I completely forgot to talk about Internet of Things devices (IOT). These are things like your webcams, smart fridges, routers, cell phones, toys, etc. These devices all run servers that can be accessed externally and if you don’t change the default passwords or cut them off from the outside network on your router they can become vulnerable to being rooted and becomes bots on these DDoS networks so make sure you always change the default passwords on 100% of the IOT devices you have in your house. Go do it now! If you enjoyed the video please give it a ‘like’. – DDOS Attacks

▼ Questions & Answers ▼
Q) My router has DDoS protection, does that mean I don’t have to worry about this?
A) No, the DDoS protection on your router just detects when malicious packets are incoming and ignores them. These packets still need to be received by your modem or router before they can be rejected so you can still have your connection overwhelmed which means by definition this defense is a marketing gimmick only and will only defend again very old style DDoS attacks that relied you responding to traffic.
Q) Will a Virtual Machine protect me 100%?
A) No, it will be a huge leap forward but realize that some malware might actually detect if it’s in a VM and behave to some extent so you think it’s safe to move it to a real machine. So make sure you keep everything on the VM that you suspect came from a source that might not be trustworthy (torrent sites, warez, movies, music, etc).
Q) Can DDoS make my internet bill go up?
A) Yes, if you have metered or limited the internet like on your cell phone or home cable modem and the DDoS attacker hits you hard you could run out your limit and go into overtime bandwidth and have to pay a premium for each gigabyte over depending on your provider. Some providers give you unlimited and in that case, you will be okay but if you keep coming under attack they may turn off your internet for eating too much bandwidth 24/7.
Q) What about bot nets comprised of IOT devices like smart fridges, routers, doorbells, smart fridges, home security systems, etc?
A) I consider those all to fall under ‘computer’ and are still infected via mallicious software or external connections. The biggest way to protect all of your devices from becoming a part of the BOT net is to protect your internal network to prevent these devices from accepting external connections and changing all of their default passwords to something complex.
