Phishing has entered a new dimension. One were spearphishing those particular victims is as easy as spamming thousands of customers. And all that thanks to the ability of AI-powered tools.

For years, phishing and spam relied on sheer numbers: cybercriminals would hastily compose generic, often poorly written emails and distribute them to thousands of recipients. Only a few needed to fall for the bait.

However, as email security tools improved, threat actors adapted, employing new tactics to evade detection. Spear-phishing and business email compromise (BEC) emerged as prominent techniques, featuring meticulously crafted messages tailored to deceive specific targets.

This shift also saw a decline in the use of malicious payloads in phishing emails, likely to evade detection by advanced email security solutions. Consequently, social engineering became the primary tool in cybercriminals' arsenals.

This is nothing we weren't seeing and expecting: Spearphishing, near-authentic emails, sophisticated cybercriminals. But the scalability of such attacks was historically limited by the time-consuming process of crafting convincing emails. But then, almost overnight, generative AI (GenAI) happened and has revolutionized phishing by drastically increasing the speed and scale of content creation.

Researchers identified GenAI's potential to enhance phishing campaigns as early as 2021, with OpenAI's ChatGPT demonstrating the ability to generate sophisticated phishing emails rapidly. GenAI tools quickly became indispensable for hackers.

Attackers are now able to produce expertly crafted social engineering content in seconds. Moreover, these tools offer versatility in generating content across various formats, styles, and languages, providing unprecedented scalability to cybercriminal operations.

As AI-driven threats evolve, organizations must prepare to combat these challenges. However, a significant cybersecurity workforce gap poses a formidable obstacle, with many organizations lacking the tools and talent to respond effectively to cyber incidents.

AI and machine learning-enabled email security solutions offer a promising defense against advanced phishing threats. These solutions not only detect threats directly but also learn and adapt over time, improving efficacy. 

Regardless, AI-enabled security tools are most effective when used to complement human expertise. Employees play a crucial role in scrutinizing flagged emails and contributing insights to catch sophisticated attacks. Organizations should prioritize security awareness training and phishing simulation testing. Continuous training, relevance to current threats, and personalization based on employee profiles are essential for an effective program.
