The RI Advice Group Breach

In August 2020, the RI Advice Group experienced a significant cyber security breach. The breach was notable for the hacker's prolonged access, spending 155 hours logged in without detection. This incident highlighted severe deficiencies in the company's cyber security infrastructure, including passwords stored in text files on the server desktop.

The Australian Securities and Investments Commission (ASIC) took legal action against the RI Advice Group for their inadequate cyber security measures. This case marked a pivotal moment as it was one of the first instances where a company faced legal consequences for failing to protect against cyber threats.

In response to the breach, several preventive measures were recommended:

  • Implementing multi-factor authentication (MFA) to enhance login security.

  • Regularly updating and patching software to fix vulnerabilities.

  • Conducting frequent security audits to identify and mitigate risks.

  • Providing comprehensive cyber security training for employees.

Canon's Ransomware Attack

Incident Overview

In August 2020, Canon faced a significant ransomware attack that resulted in the leakage of sensitive data online. The attackers demanded a ransom, but Canon refused to negotiate, leading to the public release of the compromised data. This incident highlighted the growing threat of ransomware attacks on major corporations.

Response and Recovery

Canon's response involved immediate containment measures and a thorough investigation to understand the extent of the breach. The company worked with cybersecurity experts to mitigate the damage and restore affected systems. Key steps in their response included:

  1. Isolating infected systems to prevent further spread.

  2. Engaging with cybersecurity firms for forensic analysis.

  3. Communicating with stakeholders about the breach and ongoing recovery efforts.

Impact on Stakeholders

The ransomware attack had a profound impact on various stakeholders, including:

  • Employees: Potential exposure of personal and professional data.

  • Customers: Risk of personal information being misused.

  • Business Operations: Temporary disruption of services and potential financial losses.

The Canva Data Breach

Breach Details

In May 2019, news broke that hackers had infiltrated Canva's system. The cybercriminal, identified as Ghosticplayers, breached Canva's defenses but was stopped by Canva when they detected malicious activity in their systems. Unfortunately, this interception did not happen soon enough. The threat actor had time to access user data, including usernames, real names, email addresses, country data, encrypted passwords, and partial payment data. Canva quickly notified affected accounts and took steps to mitigate the damage.

User Data Compromised

The breach impacted approximately 137 million users. The compromised data included:

  • Usernames

  • Real names

  • Email addresses

  • Country data

  • Encrypted passwords

  • Partial payment data

Security Enhancements Post-Breach

Following the breach, Canva implemented several security enhancements to protect user data better. These measures included:

  1. Resetting passwords for all affected accounts.

  2. Enhancing system monitoring to detect malicious activity more quickly.

  3. Implementing additional encryption measures for sensitive data.

  4. Conducting a thorough security audit to identify and address vulnerabilities.

Government Data Breaches

AFP Officer Data Leak

The AFP Officer Data Leak was a significant incident that exposed sensitive information of law enforcement personnel. This breach had serious implications for the safety and privacy of the affected officers. The data leak highlighted the vulnerabilities in the government's data protection mechanisms.

Victorian Government Documents on Dark Web

In a concerning event, confidential documents from the Victorian Government were found on the dark web. This breach raised alarms about the security of government-held information and the potential misuse of such data. The incident underscored the need for robust cyber security measures to protect sensitive information.

National Security Implications

Government data breaches have far-reaching national security implications. The exposure of sensitive information can compromise national security operations and put the country at risk. It is crucial for the government to implement stringent security protocols to prevent such breaches and safeguard national interests.

Australia's Position in Global Cyber Security

Survey Results

Australia has been highlighted in a global survey as one of the most-hacked countries, underscoring the rising problem of data breaches and cyber-crime. This survey reflects the increasing frequency and sophistication of cyber-attacks targeting Australian entities.

Comparative Analysis

When compared to other nations, Australia's cyber security measures are evolving but still face significant challenges. The Australian Signals Directorate (ASD) has admitted that proposed security frameworks only raise the baseline of security. It is crucial for individual businesses to implement additional data breach prevention controls to enhance their security posture.

Future Outlook

Australia is taking steps to bolster its cyber security defenses. The appointment of the country's first national cyber security boss, a long-serving Air Force chief, marks a significant move towards a more coordinated and robust response to cyber threats. However, the responsibility also lies with businesses to continuously improve their security measures.

Common Vulnerabilities Leading to Breaches

Weak Password Practices

Weak password practices remain one of the most common vulnerabilities leading to cyber breaches. Simple and easily guessable passwords make it easier for attackers to gain unauthorized access to systems. Implementing strong password policies and multi-factor authentication can significantly reduce this risk.

Inadequate Cyber Security Infrastructure

Many organizations suffer from inadequate cyber security infrastructure, leaving them exposed to various types of cyberattacks. This includes outdated software, lack of regular updates, and insufficient network security measures. Regular audits and updates are essential to maintain a robust security posture.

Employee Training and Awareness

Human error is a significant factor in many cyber breaches. Employees often fall victim to phishing and social engineering attacks due to a lack of awareness. Comprehensive training programs can help employees recognize and avoid potential threats.

Common Types of Cyberattacks

  • Malware

  • Denial-of-Service (DoS) Attacks

  • Phishing

  • Spoofing

  • Identity-Based Attacks

  • Code Injection Attacks

  • Supply Chain Attacks

  • Social Engineering Attacks


In conclusion, the recent cyber security breaches in Australia underscore the critical importance of robust cyber defenses for businesses of all sizes. By understanding how these breaches occurred and the impact they had, Australian businesses can take proactive measures to safeguard their own data and avoid similar pitfalls.
