Understanding Cyber Threats

Cyber threats are a digital shadow lurking in today’s tech-driven world. They represent a spectrum of malicious activities. These aim at harming data, pilfering confidential information, or unsettling the digital equilibrium. In Perth and across WA, where businesses are ever more intertwined with digital technology, the stakes are high.

Understanding these cyber threats is critical in an era where digital attacks are increasingly sophisticated. The landscape of cyber threats is vast, affecting companies in ways that range from minor inconveniences to catastrophic data breaches.

Protecting information goes beyond data security. It’s about maintaining your business’s integrity and ongoing operations. Cyber threats are constantly evolving and increasing. Staying informed and prepared is crucial in this unseen yet ever-present battle.

Types of Cyber Threats


Malware, short for ‘malicious software’, encompasses various forms of harmful software designed to infiltrate and damage computer systems. This includes:

  • Viruses: Programs that replicate themselves and spread to other devices, corrupting files and impairing system functionality.
  • Worms: Similar to viruses, worms can replicate and spread independently, often exploiting vulnerabilities in software.
  • Trojans: Disguised as legitimate software. Trojans deceive users into loading and executing the malware on their systems. They can steal data, install more malware, or create a backdoor to the system.

Phishing Attacks

Phishing scams use deceptive communications, often appearing as legitimate emails, messages, or websites. They intend to trick people into divulging sensitive information like passwords or financial details. Variants of phishing include:

  • Spear Phishing: Targeted at specific individuals or organisations with personalised messages.
  • Whaling: Aimed at high-profile targets like executives, using highly customised tactics.
  • Smishing and Vishing: Phishing via SMS (Smishing) and voice calls (Vishing), exploiting other communication channels.


Ransomware is a type of malware that encrypts a victim’s files or locks users out of their systems, demanding a ransom for the decryption key. Its impact is twofold:

  • Data Lockdown: Preventing access to crucial business data, causing operational disruptions.
  • Monetary Loss: Alongside the ransom demand, businesses face indirect costs from downtime and potential data loss.

Identity-Based Attacks

Identity-Based Attacks involve cybercriminals using stolen or fabricated identities to gain unauthorised access to systems and data. These attacks are particularly hazardous due to:

  • Trust Exploitation: Attackers use legitimate credentials, exploiting the inherent trust in existing security systems.
  • Access to Sensitive Data: Once access is gained, attackers can reach sensitive, confidential information, leading to significant data breaches.
  • Difficult Detection: The use of valid credentials often makes these attacks harder to detect and counter, allowing prolonged unauthorised access.

Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks

These attacks aim to overload systems, servers, or networks with overwhelming traffic, rendering them inoperable. The key elements are:

  • Volume-Based Attacks: Flooding the network or server with immense traffic.
  • Protocol Attacks: Exploiting server resources or intermediate communication equipment.
  • Application Layer Attacks: Targeting the web application layer with seemingly legitimate requests.

Man-in-the-Middle (MitM) Attacks

MitM attacks involve intercepting communication between two parties without their knowledge. Common techniques include:

  • Eavesdropping: Capturing and listening to private communications.
  • Session Hijacking: Exploiting a legitimate session to gain unauthorised access to information.
  • Wi-Fi Interception: Compromising unsecured or poorly secured Wi-Fi networks to intercept data.

SQL Injection

SQL injection attacks occur when an attacker inserts malicious SQL code into a database query. This can:

  • Compromise Database Integrity: By altering, stealing, or deleting data.
  • Bypass Application Security Measures: Allowing unauthorised access to sensitive information.
  • Lead to Further Attacks: Such as planting backdoors or spreading malware within a network.

Zero-Day Exploits

Zero-Day exploits are attacks on software vulnerabilities that are unknown to the software developer and users. They are particularly dangerous due to:

  • No Existing Defence: The lack of awareness about the Spoovulnerability leaves systems defenceless.
  • Rapid Exploitation: Attackers can swiftly exploit these vulnerabilities before they are patched.
  • Unknown Impact: The consequences of such exploits can be unpredictable and wide-ranging.


Spoofing is a cyber threat where an attacker disguises communication from an unknown source as being from a known, trusted source. This can be particularly hazardous due to:

  • Deceptive Appearance: The attacker mimics legitimate sources, leading users to mistakenly believe the communication is safe.
  • Information Theft: Spoofing often aims to steal sensitive information, as users are more likely to trust and respond to familiar sources.
  • Unauthorised Access: By using spoofed credentials or sources, attackers can gain access to restricted areas, leading to further security breaches.

DNS Tunnelling

DNS Tunneling is a cyber attack technique where cybercriminals exploit the Domain Name System (DNS) to sneak malware or exfiltrate data from a network. Its dangers arise from:

  • Bypassing Security Measures: As DNS is a trusted system, tunnelling can evade conventional network security tools like firewalls and intrusion detection systems.
  • Data Exfiltration: Cyber attackers can stealthily extract sensitive data from a compromised network without raising alarms.
  • Persistent Threat: Once established, DNS tunnelling can be used for ongoing malicious activities, making it a prolonged threat to network security.

Supply Chain Attacks

Supply Chain Attacks occur when cybercriminals target less secure elements in a supply network to compromise the security of all entities involved. These attacks are particularly dangerous due to:

  • Multiple Targets: By breaching one element of the supply chain, attackers can potentially access the data and systems of all entities within that network.
  • Hard to Detect: These attacks can be difficult to identify, as they often originate from trusted sources within the supply chain.
  • Widespread Impact: A single attack can have far-reaching consequences, affecting numerous organizations and individuals connected through the supply chain.

Impact of Cyber Threats on Businesses

Cyber attacks can result in severe financial losses, damage to reputation, and legal repercussions for businesses. In Perth and WA, where technology is integral to business operations, the impact of cyber threats can be even more pronounced.
