Phishing has been one of the oldest tricks in the cybercriminal’s handbook, and while its initial form might seem outdated, phishing has adapted and evolved over time to become more sophisticated, more personalized, and far more difficult to detect. What once was a simple email asking you to click a link or enter your personal details has now transformed into highly targeted, highly convincing scams that can fool even the most cautious of individuals and organizations. Whether it’s a suspicious phone call, a text message, or an email that looks just like it’s from your boss, phishing is a danger we all face daily.
In this blog, we’ll dive deep into the evolution of phishing, exploring its early days, how it has transformed over time, and how attackers are using artificial intelligence (AI) to craft more convincing scams. Along the way, we’ll provide some helpful tips on how you can avoid falling victim to these ever-evolving threats.
The Origins of Phishing: Simple Scams with Big Consequences
The term “phishing” was coined in the late 1990s, and it all started with emails that looked like they were sent from trusted entities such as banks or credit card companies. These emails often used scare tactics or promises of free money to get recipients to click on a malicious link or download a virus-infected attachment. While they were often riddled with spelling and grammatical errors, their simplicity made them easy to spot for tech-savvy users. However, many others still fell victim to these attacks.
The Early Days of Phishing
In the late 1990s, phishing emails would often impersonate popular companies, with messages claiming that your account had been compromised or that you needed to verify some personal details to avoid your account being locked. The emails were generally quite easy to spot, with generic subject lines like “Account Verification Needed” or “Immediate Action Required.”
These early phishing attempts were mostly massive email campaigns that targeted large numbers of people at once. It wasn’t about tricking just one person—it was about getting as many people as possible to click on a link or open an attachment.
For instance, an email might look like it was coming from a bank like Bank of America, asking you to click a link and enter your account credentials. Clicking on that link would redirect you to a fake website that looked almost identical to the real bank site. The attackers would then steal your login information and, depending on your online behavior, use that information to access your bank account or perform other fraudulent activities.
How Attackers Got Creative with Phishing
In its early years, phishing wasn’t particularly targeted—it was mostly spam. But over time, attackers began to refine their strategies, realizing that personalized phishing was far more effective. Enter spear-phishing—a more targeted form of phishing where the attacker does their homework, gathering information about their victim to create a more convincing, individualized attack.
Spear Phishing: When the Attack Gets Personal
While traditional phishing used generic messages sent to thousands or even millions of potential victims, spear phishing targets specific individuals or companies. Instead of sending a generic email with a warning that your account has been compromised, spear phishing emails look personal. They may come from someone you know—perhaps your boss, a colleague, or a business partner. The attacker might even use information from your social media profiles to tailor the email.
For example, imagine you receive an email that looks like it’s from your manager asking you to approve a purchase order. The email looks legitimate, with the same tone and language you’re used to. The attacker might include information about a project you’re working on together, making the email seem even more credible. The goal? To get you to click on a malicious link, download a harmful attachment, or—most dangerously—share sensitive information.
The personalization of spear-phishing emails is what makes them so effective. When attackers can craft emails that resonate with the victim, the chances of success skyrocket. It’s not just a random message anymore; it’s something that feels legitimate.
Vishing: Phishing by Phone
Phishing isn’t just limited to emails anymore. As technology advanced, attackers found new ways to deceive their targets. One of the most common phishing techniques today is vishing, which stands for voice phishing. In vishing, the attacker will impersonate someone over the phone in an attempt to gain access to personal or financial information.
How Vishing Works
Vishing often starts with a phone call or voice message from someone claiming to be from a reputable company, like your bank or your internet provider. The attacker might claim there’s an issue with your account, or that there’s been suspicious activity. They’ll ask you to verify your personal information over the phone, such as your bank account number, Social Security number, or other sensitive details.
In some cases, the attacker may use social engineering tactics to create a sense of urgency. For example, they might say, “Your account will be frozen unless you act immediately,” pushing you to give them the information they want without thinking twice.
Some vishing attacks even take place over voicemail. The attacker leaves a message saying that they are calling from a company you recognize, telling you to call back the provided number. But when you call back, you’re connected to the attacker, who will attempt to get you to share sensitive details.
Spotting Vishing Scams
To avoid falling victim to vishing, always be cautious when you receive unexpected calls requesting sensitive information. Verify the caller’s identity and don’t provide any personal details until you’re certain that the call is legitimate. It’s often best to call the company directly using a number from their official website, rather than calling back the number provided in the voicemail.

Smishing: Phishing via Text Messages
As mobile devices became more prevalent, smishing emerged as another form of phishing. Smishing is phishing carried out via SMS (text messages) instead of email or phone calls. Attackers use text messages to trick users into clicking on malicious links or providing personal information.
How Smishing Works
A smishing attack often starts with a text message that looks like it’s from a reputable source—your bank, a delivery service, or even the IRS. The message might say, “Your package has been delayed. Click here to reschedule delivery,” or “We need to verify your bank account. Click here to update your information.”
The link in the message will often take you to a fake website, designed to look just like the real one. If you enter your personal information on this site, the attackers will steal it.

How to Protect Yourself from Smishing
To protect yourself from smishing, don’t click on links in unsolicited text messages. Instead, go directly to the official website of the organization or call their customer service to verify the legitimacy of the message.
AI-Powered Phishing: The Future of Deception
One of the latest and most concerning developments in phishing is the use of artificial intelligence to craft even more convincing phishing attacks. AI is helping cybercriminals create phishing emails, phone calls, and even fake videos that look and sound like real people.
How AI is Changing Phishing
AI tools can now analyze vast amounts of data, learning how people communicate and creating emails that are practically indistinguishable from those sent by real individuals. AI can even tailor the content of the email to specific individuals, using social media profiles and other publicly available information to make the message more convincing.

For example, an AI-powered phishing email might use your writing style or reference conversations you’ve had online, making the email seem like it came from a colleague or friend. Or, an AI might create a video or voice message that looks like a company executive, asking you to transfer money or provide sensitive data.
The future of phishing looks increasingly sophisticated, and AI is at the forefront of this new wave of cyberattacks.
How to Protect Yourself from Phishing in 2025 and Beyond
While phishing attacks have become more sophisticated, there are steps you can take to protect yourself and your organization:
- Be Cautious with Unsolicited Communication: Whether it’s an email, phone call, or text message, always verify the legitimacy of unsolicited requests for sensitive information.
- Use Multi-Factor Authentication (MFA): MFA adds an extra layer of protection to your accounts. Even if a cybercriminal gets your password, they won’t be able to access your account without the second factor of authentication.
- Educate Yourself and Your Employees: Stay up to date on the latest phishing trends and make sure everyone in your organization knows how to spot a phishing attack.
- Use Anti-Phishing Tools: Many email providers and web browsers offer tools that can help detect and block phishing attempts. Use these tools to add an extra layer of defense.
