CYBER WATCH
• DNS Spoofing: Assuming the DNS name of another system by either cor- rupting the name service cache of a victim system, or by compromising a domain name server for a valid domain.
• Flooding: Involves inserting a large volume of data into a computer net- work, resulting in a denial of service.
• Malicious Code: Software capable of performing an unauthorized process on an information system.
• Packet Sniffer: A device or program that monitors the data travelling be- tween computers on a network.
• Probe: An attempt to gather informa- tion about an information system for the apparent purpose of circumventing its security controls.
• Retro-virus: Waits until all possible back-up media are infected too, so that it is not possible to restore the system to an uninfected state.
• Rootkit: A hacker security tool that captures passwords and message traffic to and from a computer. A
collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network, mask the fact that the system is compromised, and much more.
• Smurfing: Software that mounts a de- nial of service attack by exploiting IP broadcast addressing and ICMP ping packets to cause flooding.
• Spam: Indiscriminately sending unso- licited, unwanted, irrelevant or inap- propriate e-mails.
• Spoofing: Impersonating another person or computer, usually by pro- viding a false e-mail name, URL or IP address.
• Spyware: Software that collects infor- mation about a person or organization without their knowledge or informed consent and reports data back to a third party.
• Virus: Self-replicating, malicious code that attaches itself to an application program or other executable system
component and leaves no obvious signs of its presence.
• Worm: Independent program that repli- cates from machine to machine across network connections often clogging networks and information systems as it spreads.
These are just some of the more common cybercrime terms and tech- niques that all computer users must know and protect themselves against. And now that you know about all of these “cute” hacking labels, don’t rest easy as new types of cyber attacks are being de- veloped every single second, of every single day.
