6. Clone Phishing: Replicating legitimate emails and sending them with malicious links or attachments, claiming they are updated.
7. Website Phishing: Creating fake websites that mimic legitimate ones to steal user credentials and personal information.

4. Historical Background of Phishing

4.1. Early Days of Phishing: Initial Techniques and Targets Phishing first appeared in the mid-1990s, mainly targeting America Online (AOL) members. Early phishers from a group known as the Warez community used algorithms to generate random credit card numbers to create fake AOL accounts. These accounts were used for various fraudulent activities, including spamming other users. When AOL implemented measures to combat these fake accounts in 1995, phishers adapted by posing as AOL employees, sending emails and instant messages asking users to verify their account information. This strategy was highly effective because users were not yet familiar with such scams[1].

4.2. Evolution of Phishing Attack Over Time:

Phishing tactics have evolved significantly over time. The “Love Bug” virus of 2000 marked a major shift in phishing techniques. This worm infected millions of users worldwide by tricking them into opening an attachment in an email with the subject “ILOVEYOU,” which then infected their systems with malware. By the early 2000s, phishing attacks began targeting e-commerce websites and online payment systems. A notable attack occurred in 2001, targeting the E-Gold payment system. By 2003, phishers were using fake emails and domain names mimicking popular websites like PayPal and eBay to trick users into revealing personal information.

In subsequent years, phishing became more sophisticated. In 2004, phishing became a lucrative business as cybercriminals used techniques like pop-up windows to collect sensitive information. The rise of social media in the late 2000s provided phishers with abundant personal information, leading to more targeted and personalized spear phishing attacks. Phishing techniques continued to evolve. For instance, in 2013, phishing emails were used to distribute the CryptoLocker ransomware, which encrypted victims’ files and demanded a ransom for decryption. Attackers also began using HTTPS to make phishing sites appear more legitimate, exploiting the false sense of security users associated with the browser’s padlock icon.

Today, phishing remains one of the most significant online threats, continually adapting to technological advancements and exploiting human psychological weaknesses. The increasing sophistication of phishing attacks underscores the need for education and robust cybersecurity measures to protect individuals and businesses from these evolving threats[5]. Fig 2. Explains Evolution of Phishing Attack Over Time.

5. Current Evolution of Phishing

5.1. Modern Techniques

Use of Social Engineering Social engineering remains a core strategy in modern phishing attempts. Attackers manipulate emotions to instill fear, trust, or urgency. They often impersonate trusted individuals or organizations, using personal information to make their messages more convincing. Psychological manipulation is central to spear phishing, where emails are highly tailored to the recipient, increasing the likelihood of success.

Advanced Phishing Kits and Tools With the rise of advanced phishing kits, even less technically skilled attackers can now launch sophisticated attacks. These kits often include pre-made phishing pages, email templates, and automation tools. Phishing as a Service (PhaaS) has also emerged, where cybercriminals rent out their phishing operations on dark web markets, lowering the barrier to entry and increasing the frequency and sophistication of phishing attacks.

Phishing as a Service (PhaaS) PhaaS platforms offer comprehensive services, from crafting phishing emails to managing the infrastructure needed for an attack. This approach has broadened the pool of potential attackers by enabling even those with limited technical skills to launch phishing attacks. These services are often marketed on dark web forums and private messaging channels, facilitating the professionalization and commercialization of phishing.

5.2. Targeted Attacks

Industry-Specific Phishing Campaigns Cybercriminals are increasingly tailoring their attacks to specific industries, such as technology, healthcare, and finance.
