Types of hacking attacks

[AarzaK]

Hello!

Welcome to the Antionline community!

I am not a software security expert, but I am found it in google.

There are five forms of attacks commonly used against computers and networks, according to Aaron Turpen, in his article 'Hacker Prevention Techniques.'

1. Distributed Denial of Service (DDoS) attacks
* usually aimed at networks by third party systems (typically, compromised systems lacking security that unwittingly become hacker accomplices)
* focuses on open ports and connections in the network or system
* they undermine the network by flooding it with requests and "pings," thereby causing one or more systems and their resources to shut down or crash
* major systems usually recover from such attacks easily and completely

2. Trojan Horse
* software disguised as something else (typically useful shareware or freeware) and so are installed in your system consciously
* it either contains
o a "back door," (which allows others to enter your system, and do what they want with it, while you're using the software), or
o a "trigger," (sets itself off when triggered, either by a date or a time or a series of events, etc., and cause your system to shut down or attack other computers; can be part of a DDoS attack
* SpyWare is a less malicious version (it fills commonly-used form fields for you while also collecting information to send to advertisers and marketing companies)
* difficult to detect
3. Virus
* most common
* primary concern is to replicate and spread itself, and then destroy or attempt an attack on the host system
* examples include: I Love You; Crazy Boot, Cascade; Tequila; Frodo
4. Websites - malicious sites that use known security holes in certain Web technologies to trigger your web browser to perform unwanted functions in your system (ex. an older version of ActiveX had a "hole" that allowed content in any one folder or directory on your hard drive to be automatically uploaded to a web directory or emailed to a receiver)
5. Worm
* it consumes resources (quietly) until the system finally becomes overloaded and ceases to function
* a combination of a DDoS and a virus attack
* usually reproduces as often as possible to spread as widely as they can
* typically built for a certain type of system and is benign to all others
* commonly aimed at larger systems (mainframes, corporate networks, etc.); some are built to "consume" data and filter it back out to unauthorized users (i.e. corporate spies)
* examples are Sobig and Mydoom


Hope others guys can help you.
