It is very easy to hide data in picture, the picture can be viewed by anyone but only the person who knows about it can read the hidden letters.

Denial of service attacks:

A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. Buffer overflow attacks – the most common DoS attack. The concept is to send more traffic to a network address than the programmers have built the system to handle.

Some specific instances of cyber war:

First Cyber war was Espionage in 2007, the attacks began around the time when a monument commemorating Soviet soldiers the Bronze Soldier of Tallin was removed from the city center. First speculation's pointed to the Russian Federation as being behind this attack.

The DOS attack which lasted for three weeks targeted banks and administration infrastructure, embassies were blocked for 3 weeks, the country's information flow services were paralyzed.

The Kremlin refused to assume responsibility for the sabotage, but also admitted that it would turn out to be the large scale attack. A year later as some of you may remember Russian forces invaded Georgia standard military operations were concurrent with cyber attacks that targeted government servers torrent networks were utilized.

All the networks were redirected to government sites and that resulted in denial of service, which means all sites were blocked.

Another instance of cyber warfare occurred in 2010 when Google detected that some of their accounts set up on Google servers were being monitored. E-mail accounts that belong to Chinese dissidents were monitored by sniffer programs and stolen clank computers.
