#3 : Hacking Tips

            Denial of Service            

Distributed Denial of Service a.k.a. DDos is a malicious technique. Group of hackers send huge traffic to a webserver to make a website unavailable to legitimate users. DDos can slow down the speed of a website or force it to shut down temporarily. DDoS came into existence in 1998. 

==> Why DDoS Attack Are Conducted? 

i. Consumption of bandwidth, diskspace or processor time. 

ii. Disruption of configuration information, such as routing information. 

iii. Disruption of state information, such as unsolicited resetting of TCT Sessions. 

iv. Obstructing the communication media between the intended users and the victim so that they can no longer access the site.

Attack Types    : 

Ping of Death is based on sending the victim a malformed ping of packet, which might lead to a system crash. 
SYM Flood occurs when a host sends a flood of TCP/IP packets, often with a forged sender address. Each of these packets is handled like a connection request, causing the server to spawn a half-opened connection. 

Teardrop Attacks involves sending mangled IP graments with overlapping, oversized payloads to target machine. This can crash various OS because of a bug in their TCP/IP. 

Peer-to-Peer attack doesn't involve the attacker directly, instead he acts as a master and dictates the client to connect to victim's website.
