Artificial intelligence is significantly enhancing the success of ransomware attacks targeting Australian organizations, according to a new report. The findings indicate that AI is enabling cybercriminals to craft more sophisticated and convincing phishing, impersonation, and credential theft campaigns, making it harder for individuals and systems to detect threats. This evolution means ransomware is increasingly becoming a sustained extortion operation rather than solely an encryption event.
AI’s Growing Role in Ransomware Attacks
The 2026 AI-Era Ransomware Report, which surveyed cybersecurity professionals globally, reveals a stark reality for Australian businesses. Two-thirds (67%) of Australian organizations affected by ransomware reported that artificial intelligence has made these attacks either significantly or somewhat more effective. This widespread impact underscores a critical shift in cyberattack methodologies.
Ryan Kalember, Chief Strategy Officer at, explained that while AI hasn’t fundamentally altered the nature of ransomware itself, it has dramatically improved the preliminary stages of these attacks. “Today’s attackers are using AI to create highly convincing phishing emails, malware components like scripts, and credential theft campaigns that exploit human trust at scale,” Kalember stated. He emphasized that organizations continuing to view ransomware solely as a technical problem of encryption or recovery are overlooking its primary vector: human interaction and identity compromise.
Data Theft and Double Extortion on the Rise
Beyond the initial compromise, the report highlights that data theft is now a near-universal outcome of ransomware incidents in Australia. A significant 70% of affected organizations confirmed that data was stolen during the attack. This data exfiltration is a key component of modern extortion tactics, moving beyond simply locking systems to holding sensitive information hostage.
The report also sheds light on the persistent issue of ransom payments. Despite recommendations from law enforcement and security agencies to avoid payment, nearly half (49%) of affected Australian organizations admitted to paying a ransom. Compounding this challenge, more than half (51%) of those who paid faced a subsequent, second extortion demand. This indicates that paying the initial ransom does not guarantee an end to the threat and can, in fact, embolden attackers.
Human Trust as the Primary Target
Adrian Covich, Vice President of Systems Engineering, APJ at, noted that the perceived authenticity of attack lures was the most frequently cited reason for successful ransomware incidents in Australia. “This does not mean Australians are inherently less security-aware, instead it reflects how successfully AI can now mimic the trusted communications that keep businesses moving,” Covich commented. He pointed to recent warnings from the Australian Signals Directorate (ASD) regarding state-aligned threat actors targeting critical industries as evidence of the escalating threat landscape.
The findings strongly suggest that AI’s ability to generate highly realistic phishing emails, messages, and even voice impersonations is making social engineering attacks increasingly difficult to discern from legitimate business communications. This weaponization of human trust is a central theme in the evolving ransomware threat.
Key Australian Findings Summarized:
- AI Significantly Boosts Effectiveness: 26% of Australian organizations reported AI significantly increased attack effectiveness, with an additional 41% stating it somewhat increased effectiveness, totaling 67%. Only 11% saw no evidence of AI use.
- Human-Centric Entry Points Dominate: Phishing and email-based social engineering were the initial entry vectors in 37% of Australian incidents. Malicious attachments and links (47%) were the most common initial threats, followed by Business Email Compromise (38%) and conversation hijacking (26%).
- Data Exfiltration is the New Norm: Over two-thirds (70%) of Australian organizations confirmed data theft during ransomware incidents, indicating a shift from encryption to data acquisition for monetization or further attacks.
- Authenticity Bypasses Defenses: 41% of Australian organizations cited that employees did not suspect the attack because it appeared authentic, while 42% attributed the incident to users interacting with malicious content, highlighting AI’s role in sophisticated social engineering.
Rethinking Ransomware Defense Strategies
The report’s conclusions strongly advocate for a shift in cybersecurity strategies. Organizations can no longer afford to treat ransomware primarily as a technical malware problem. As AI enhances the believability of phishing, impersonation, and credential theft, the focus must pivot to protecting people, their identities, and the integrity of trusted communications before attackers can exploit them.
A human-centric approach to cybersecurity is paramount. This involves understanding normal communication patterns, training employees to recognize sophisticated deceptive messages, and implementing robust identity protection measures. By fortifying the human element and securing communication channels, organizations can build resilience against the increasingly AI-powered threat of ransomware.
The methodology for the 2026 AI-Era Ransomware Report involved surveying 953 full-time security professionals across various organizations and industries in 12 countries, including Australia, between March and April 2026.
