Zscaler, a company specializing in cloud security, has released the Zscaler ThreatLabZ phishing report for 2024. The document reports that in 2023, the number of phishing attacks controlled by artificial intelligence increased by 60%, and Australia was one of the most affected countries.
The report's data is based on two billion blocked phishing transactions through the Zscaler Zero Trust Exchange platform from January to December 2023, making Australia one of the top ten countries that have become the main sources of phishing attacks.
"The potential of artificial intelligence is changing the landscape of cyber threats and redefining opportunities in the world of cyber attacks, especially phishing scams. There have been 29,427,987 phishing attempts in Australia, which highlights the scale of the threat," said Eric Swift, ANZ vice president at Zscaler. "Phishing remains a constant threat, and with the advent of new technologies, it is extremely important for organizations to understand the best methods of protection against phishing attacks. The results show that a proactive approach with zero trust and the use of advanced artificial intelligence capabilities is necessary to combat new threats."
Key findings of the report include:
- An increase in attacks using Vishing (voice phishing) and deepfake phishing, where attackers use generative AI to enhance social engineering tactics.
- Australia is among the top ten countries, along with the United States, Great Britain, India and Germany, that have become targets of phishing scams.
- In Australia, the volume of phishing content increased by 479.3%.
- The manufacturing sector has become the most vulnerable in Australia, Korea, Malaysia, Singapore and Taiwan.
In 2023, there were 5,984,195 phishing attacks in the manufacturing sector and 5,776,337 attacks in the service sector in Australia. Other industries affected include technology, public administration, education, finance, insurance, retail and wholesale.
The United States (55.9%) topped the list of countries with the highest number of phishing attacks, followed by the United Kingdom (5.6%) and India (3.9%). The high prevalence of phishing in the United States is explained by the developed digital infrastructure and the widespread use of online financial transactions. Most of the attacks originated from the United States, Great Britain and Russia, while Australia entered the top 10 due to an increase in phishing content by 479% compared to the previous year.
The financial and insurance sectors recorded the largest number of phishing attempts, which is 393% more than in the previous year.
