What is Phishing?
Phishing is a type of cyber attack where attackers deceive individuals into providing sensitive information such as usernames, passwords, and credit card details. This is usually done by masquerading as a trustworthy entity in electronic communications. Phishing attacks are among the most common and damaging forms of cybercrime, leading to significant financial losses and compromised personal information.
Types of Phishing
Phishing attacks come in various forms. Here are some common types:
1. Email Phishing
This is the most common form of phishing. Attackers send emails that appear to be from reputable sources such as banks, social media sites, or online services. These emails often contain malicious links or attachments that, when clicked, lead to fraudulent websites designed to steal personal information.
2. Spear Phishing
Unlike regular phishing attacks, spear phishing targets specific individuals or organizations. Attackers conduct research to personalize their messages, making them more convincing and increasing the likelihood of success.
3. Whaling
Whaling attacks target high-profile individuals such as executives or important public figures. These attacks are highly targeted and often involve substantial research to craft believable and impactful messages.
4. Smishing
Smishing involves phishing attacks conducted through SMS messages. Attackers send text messages with links to malicious websites or prompts to share personal information directly.
5. Vishing
Vishing, or voice phishing, uses phone calls to trick victims into divulging personal information. Attackers may impersonate bank representatives, tech support, or other trusted entities.
6. Clone Phishing
In clone phishing, attackers clone a legitimate email previously sent to the victim, altering it to include malicious links or attachments. Since the email appears to come from a known sender, recipients are more likely to trust and interact with it.
Examples of Phishing
Example 1: Fake Bank Email
An email appears to be from your bank, informing you of suspicious activity on your account. It provides a link to “verify” your information, but the link leads to a fake website that captures your login details.
Example 2: Social Media Scam
You receive a message on social media from a friend saying they’ve found a great deal on an online store. The link takes you to a fake site that asks for your credit card information.
Example 3: Job Offer Scam
An email offering a lucrative job position asks you to fill out a detailed application form, including your personal information, Social Security number, and banking details.
