AI spam refers to unsolicited, low-effort content generated at high frequency, using clickbait tactics to redirect users to an outside domain and steal credentials. As fraudsters exploit this potential, what differentiates it from traditional human-crafted spam?
AI spam leverages natural language processing (NLP), a computer program’s ability to decipher how human language is written and spoken. NLP uses either rule-based or machine-learning approaches to understand language nuances, mimicking human writing styles.
This allows spammers to create hyper-realistic emails that bypass traditional filters, even personalising messages to target specific demographics. As machine learning algorithms constantly refine and automate this process with laser precision, AI spams have remarkable success rates in congesting your primary inbox folder.
AI has dramatically improved spam tactics, allowing malicious actors to create flawless texts, codes, multimedia content, and websites.

- Nearly 50% of email marketers integrate AI into their campaigns, personalising emails that yield a 13.44% uptick in click-through rate. However, this potential also gives AI spam a high success rate for phishing attacks and social engineering scams.
While three-quarters of businesses have been targeted by AI fraud, Sift Global Data Network revealed a 22% increase in blocked AI-fueled content in Q1 2024 vs Q1 2023.
Around 61% of phishing emails are AI-generated, topping the list for AI-based fraud schemes attacking industries. As AI tools craft highly convincing, error-free phishing emails, it mainly contribute to account opening and takeover in businesses.
- As email remains the top vector for phishing attacks, 52% of companies reported AI-fueled fraud daily or weekly. Meanwhile, certain industries, such as marketplaces, dating apps, and social media sites, are more prone to AI-driven attacks due to their reliance on user-generated content.
- Roughly two-thirds of businesses and consumers find it tougher to identify fraud due to increasingly persuasive AI-powered scams. As AI streamlined and escalated phishing tactics, scammers raked a record high of $10 billion in 2023 alone.
AI Spam Statistics Australia
- Australia entered the top 10 as the main origin of phishing attacks, with a 479.3% surge in the volume of phishing content hosted in the country. This can be attributed to the country’s advanced digital infrastructure, backed by sophisticated AI tools.
- Zscaler 2024 report highlights that Australia ranked 9th globally among countries targeted for phishing scams. With AI automating spam at tremendous volume and reach, it poses a greater threat to Aussies’ extensive use of online payments.
- ACCC’s Scamwatch service recorded 109,000 reports of phishing activity in Australia, resulting in losses of AU$26.1 million in 2023. The prevalence of AI-driven phishing campaigns further propelled cyberattackers’ success in exploiting unsuspecting Aussies.
- Although one-fifth of Aussies thought AI would improve the job market, over two-thirds are worried about using AI. This includes using it for potential large-scale cyberattacks, making individuals and businesses vulnerable to phishing and scams.
Despite the growing threat, public awareness of AI-powered spam in Australia remains relatively low. Given most Aussies’ superficial understanding of AI use, a national survey shows only 10% of Australians are concerned and aware of AI-enabled cyber attacks.
The Future of AI Spam: Forecasting Trends & Growth
Although human-crafted spam remains prevalent, AI spam is slowly claiming turf, as not all spammers understand how to leverage the technology yet.
As AI spam continues to evolve, it will inevitably find more clever ways to evade junk inboxes and land directly into your primary inbox.
Growth of AI Spam
The Deloitte Center for Financial Services estimates that generative AI email fraud losses could peak at US$11.5 billion by 2027. This solidifies how AI spam mirrors fine-tuned campaigns that can penetrate users’ primary inboxes at unprecedented scale and speed.
So, what drives AI spam’s success rate? While traditional spam sticks to social engineering tactics, AI spam relies on machine learning techniques. AI algorithms analyse vast user data, including online behaviour, social media profiles, and publicly available information.
This allows AI-generated spam to add a familiar touch, creating a more convincing and personalised campaign. As user behaviours change, machine learning tracks.
Evolution of AI Spam
AI spam will come in many flavours in the coming years, featuring deep fake voice calls, videos and entire spoofed websites. For instance, malicious actors launched various large language model (LLM) copycat tools to create malicious content masked in highly sophisticated email spam.
WormGPT and FraudGPT are the two most common tools, allowing those without technical expertise to participate in fraudulent activities. A recent study even outlined that well-crafted AI emails have a 0% spam flag rate, increasing the success rate of attackers extracting sensitive user data.
Meanwhile, research shows that AI worm attacks send users spam emails with zero-click malware. This exfiltrates the user’s data without the need to click or follow malicious links. Even though such attacks have been limited to research settings, expect these kinds of attacks to propagate in cyberspace eventually.
Forecast for Businesses
AI has become a double-edged sword, as threat actors and defenders use its capability. As AI spam displaces authentic email, the market forecasts that spending on anti-spam filter software will grow to US$23.56 billion by 2031, up 375% in 2023.
With AI being rapidly used as a fraud tool, enterprises not leveraging this technology are at heightened risk of cyber threats. This paints a challenging picture for virtually all industries handling sensitive information, including personal data, login credentials, or financial details.
Staying abreast of AI spam trends is key to safeguarding your business. MRC reported that 70% of merchants invest in additional tools to thwart AI-generated fraud. Meanwhile, half of corporations identify improving AI accuracy as a top priority to combat AI-powered scams.
Protect Your Business from AI Spam: Practical Tips & Tools
AI spam ceases to follow the typical spam structure, such as incorrect grammar, awkward syntax, or inconsistent details. This is why finding an AI spam is like looking for hidden needles in a haystack, mimicking legitimate messages to deceive you in plenty of ways.
Here are a few actionable ways to protect your email programs against the evolving spam risks in the age of AI.
AI-Powered Spam Filters
AI-powered spam filters use machine learning to proactively identify and block malicious emails, attachments, and URLs. Its algorithm analyses subtle patterns and anomalies that traditional filters miss, providing an added defence against sophisticated phishing campaigns.
With advanced natural language processing, AI filters decipher context, tone, and intent to discern legitimate emails from spam. These filters constantly learn and adapt, sidestepping authentic emails being flagged as spam and blocking evolving spam tactics.
Email Authentication
Email authentication protocols like SPF (Sender Policy Framework) verify email origin, ensuring you receive messages from trusted sources. Another protocol is DKIM (DomainKeys Identified Email), which adds digital signatures to indicate emails haven’t been altered in transit.
So, what happens when AI spam bypasses these? This is where DMARC (Domain-based Authentication, Reporting & Conformance) enters, specifying what actions you can take if an email fails authentication checks. This circumvents your domain from being associated with malicious purposes, building recipient trust and confidence.
Adopt Zero Trust Architecture
This modern approach treats every user and device as potentially untrusted to avoid breaches from both internal and external sources. It enforces strict access controls and continuous monitoring to limit the radius of successful attacks, including AI-powered threats.
Employee Training
As AI automate attacks with greater speed, sophistication, and scale, timely training is critical to avoid the pitfalls of AI scams. Teach employees how to spot suspicious emails, verify sender authenticity, and promptly report any security incidents. This fosters a security-conscious culture so employees can fortify the company’s cybersecurity posture.
Regular Security Audit
Conducting regular security audits helps uncover vulnerabilities in your email security. Simulate phishing attacks to identify gaps and test your organisation’s response capabilities. These practices gauge how mature your security measures are to fend off AI-generated phishing and scam emails.
