Cybercrime

Cybercrime

There are various types of cybercrimes which target individuals, businesses, even the government.

There are three primary categories of pure cybercrime.

 

1.  Computer Access Crimes.

These occur where cybercriminals are able to access a computer or network without permission, and subsequently obtaining one’s personal information such as address, credit card numbers, documents or personal photos or videos.

 

2. Computer Disruption Crimes.

This activity targets computer systems and networks in such a way to cause them to slow down or cease working completely.

Someone may even be blocked from using the device or files through encryption techniques.

These attacks may include a ransom message demanding payment in exchange for the system to be restored.

3. Computer Malfunction Crimes.

This involves a malfunction of the computer or its network that does not involve a complete disruption to the computer system.

 

What are the Most Common Forms of Cybercrimes ?

A. Phishing

Phishing is the most common form of cybercrime.

It is a form of online fraud that almost everyone has encountered at one point or another.

It involves scammers posing as large organisations such as the Australian Taxation Office, or financial intuitions by sending emails or texts which contain a link to a fake website.

If you follow the link and the prompts, cybercriminals can steal your personal information.

B. Identity theft

Identity theft has become a common occurrence in Australia.

This is where cybercriminals are able to gain access to someone’s personal information. Often this information is on-sold to buyers over the dark-web. Those buyers use then use the personal information to open bank accounts and apply for credit.

C. Hacking

Hacking’ is also one of the most common offences and involves unauthorised access to computer systems.

This usually leads to ransomware, which some business will pay to avoid the shame of reporting that their systems where successfully hacked.

D. Denial-of-service

Denial-of-service or DOS attacks are usually targeted at high-profile organisations such as banking, media or government agencies.

They are intended to shut down networks or deny access to its users.

In 2020, Australian businesses and governments were targeted by DOS attacks.

The level of sophistication required is much higher, thus leaving the Prime Minister accusing a foreign Government to be behind it.
