Cyber security threats and attacks are growing worldwide and the larger hacks, like Optus and Canva are better known for obvious reasons, but larger corporations like these have the budgets to invest in large-scale cyber security protections and agencies. This has led cyber criminals to pivot towards small and medium businesses that are less likely to have inhouse teams or large agencies to protect their data and systems.

What is a Cyber Attack?

A cyber attack refers to an unauthorized and malicious attempt to gain access to, disrupt, or damage computer systems, networks, devices, or data. Cyber attacks can be carried out by individuals, groups, or even nation-states, with the intention of stealing sensitive information, causing disruption, or inflicting harm for various motives, including financial gain, political or ideological reasons, or simply for malicious intent.

There are numerous types of cyber attacks, including but not limited to:

Malware: Malicious software that is designed to infiltrate or damage computer systems, such as viruses, worms, and ransomware.

Phishing: An attempt to deceive individuals into revealing sensitive information, such as usernames, passwords, or financial data, by posing as a trustworthy entity through emails, messages, or websites.

Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks: Overloading or flooding a system or network with traffic to render it unavailable or unusable.

Social engineering: Manipulating individuals into divulging sensitive information or performing actions that may compromise security, often through psychological manipulation or deception.

Insider threats: Attacks perpetrated by individuals with authorized access to a system or network who abuse their privileges for malicious purposes.

Zero-day exploits: Exploiting unknown vulnerabilities or weaknesses in software or systems before they are patched, allowing unauthorized access or control.

Advanced Persistent Threats (APTs): Coordinated and sophisticated attacks targeting specific organizations or entities over a prolonged period of time, often aimed at stealing sensitive information or conducting espionage.

The consequences of cyber-attacks can be severe, resulting in financial loss, reputational damage, legal and regulatory implications, and disruption of critical infrastructure.
