Worms may be called the cousins of viruses. The difference between viruses and worms is that worms infect the gadget without any type of assistance from the user. The first step that worms take is to scan the computer systems and exploit vulnerabilities. Then it copies itself onto the device infecting the system, and the process is repeated.
Passive Types of Computer Attacks
As the call shows, hackers will sneakily listen to the verbal exchange happening among two computer systems at the network. This can happen in a closed gadget in addition to over the net as well.

Here the hackers profits get entry to the pc and the network assets with the aid of gaining password manipulate. It is frequently visible that the attacker changes server and community configuration and in a few instances may also even delete information. Data also can be exceeded onto one of a kind networks.
Denial of Service Attack
As the call suggests, hackers will sneakily concentrate to the communication going on among two computers on the network. This can occur in a closed system as well as over the net as nicely. The other names with which this is mentioned is sniffing or snooping. With eavesdropping, touchy data can make its manner over the network and may be available to others.
Compromised Key Attack
