Phishing is a type of social engineering attack where cybercriminals attempt to trick someone into revealing sensitive information. Here’s a look at phishing through an ecommerce lens: impersonating a trusted person or entity, like a supplier, a payment processor, or even a customer, to steal login credentials, financial details, or personal data.

These attacks take advantage of human behavior, not just network vulnerabilities. All it takes is a convincing email and a busy, distracted employee who unknowingly clicks a malicious link or downloads a compromised attachment. The attacker then has a foothold to wreak havoc on your endpoints and identities. They’ll invite themselves to stay for a while with persistence techniques, steal customer data, reroute payments to their own bank accounts, and disrupt your entire supply chain.

Modern phishing attacks are well-crafted and highly targeted at ecommerce retailers, making them tougher to spot.

Here are four common types of phishing attacks that target ecommerce businesses:

• Email phishing is the most common form of phishing. Attackers send emails that look like they're from a genuine, trustworthy source, like a bank, a major software company, or a government agency. The messages usually have a sense of urgency, so the recipient quickly clicks a link or downloads a malicious file, thinking they’ve resolved a supposed issue.
• Unlike broad email phishing campaigns, spear phishing is highly targeted. Attackers research their victims, often specific employees or departments within a company, and create personalized messages. For an ecommerce business, this could be an email pretending to be from a key supplier with a new invoice attached or a message seemingly from the CEO requesting a money transfer ASAP.
• Whaling is a type of spear phishing that targets high-profile individuals, like the CEO, CFO, or other C-suite members. Since these individuals have access to the inner workings of the business and the authority to sign off on big transactions, a successful whaling attack can be catastrophic.
• Smishing uses text messages (SMS) to trick victims, while vishing uses voice calls. In an ecommerce environment, an online retailer might get a text message about a supposed delivery issue with a link to a fake tracking site, or a phone call from someone pretending to be from their supplier asking for account details right away to prevent supply chain disruptions.

To understand how these attacks go down, let's break down a common scenario for an ecommerce business.

Imagine you run an online store selling dog sweaters. One morning, you receive an email with the subject line, "Urgent: Your Payment Account Has Been Suspended." The email looks like it's from your payment processor. It has the company’s logo, accounts payable rep email signature, and official-looking formatting. But this seems phishy: “Due to a security update, your account has been temporarily frozen, and you need to verify your details to reactivate it.” You’ve worked with this payment processor for a while, and this raises your security hackles.

But you’re on the heels of Black Friday, and this is your biggest week of the year with a huge sale on Christmas-themed merch. The email has a quick fix for you with a button that says, "Verify Your Account Now." You feel a surge of panic about potentially dropped sales numbers, so you click the link. It takes you to a webpage that looks identical to your payment processor’s login page—seems okay. You quickly enter your username and password, and the page refreshes, taking you to the real homepage of the processor. It might seem like your payment “issue” is resolved, but in reality, you've just handed over your login credentials directly to a cybercriminal.

This is a classic example of a phishing scam targeting ecommerce businesses. The attacker used urgency, created a sense of panic, and a convincing disguise with a well-crafted email to trick you into giving up sensitive information.

To protect against phishing attacks, ecommerce users should know how to spot the 4 Ps of phishing: pretend, problem, pressure, and pay.

Pretend

Watch out for messages that pretend to be a legit entity. Attackers impersonate trusted authorities, like banks, government agencies, or corporations, to make their requests seem real.

Problem

You get a message about a sudden problem that cropped up out of nowhere. Since issues like this usually don’t come up, the attacker doesn’t want you to second-guess anything.

Pressure

The message makes you feel pressure to act fast. If you don’t act on the request right now, there will be consequences: your account will be frozen, you may face legal action, or you may be penalized with hefty fines.

Pay

If you get emails, text messages, or phone calls with all of the above and a demand to make payments, you’re getting phished. Attackers want your sensitive information and money, and they’ve almost got it.

Knowing how to spot phishing isn’t just for your IT department. Everyone can and should play a part in securing your business against phishing scams. Check out these tips and tricks to keep your ecommerce storefront secure:

• Report suspicious emails: Encourage employees to report any suspicious emails to your IT department or security team immediately. This helps spot threats early in the attack path.
• Stay informed: Keep up with the latest phishing trends and tactics. The cybersecurity landscape is always changing, and staying in the loop is crucial for strong defense.
• Employee training: Regularly train your team to catch phishing red flags with Managed Security Awareness Training (SAT)
• Multi-factor authentication (MFA): Add MFA wherever possible. Even if an attacker steals a password, they’ll get blocked and have to use more advanced tactics to bypass MFA.
• Identity security: Roll out Managed Identity Threat Detection and Response (ITDR) to monitor and protect your identities and email in Microsoft 365.
• Check the sender: Verify the sender's email address. Attackers often use domains that are slightly different from the legitimate one, like payment-gateway.co instead of payment-gateway.com.
• Look for red flags: Watch out for poor grammar, spelling mistakes, generic greetings ("Dear Customer"), and urgent language.
• Hover before you click: Before clicking any link you get in an email or text, hover your mouse over it to see the actual destination URL. If it looks sketchy, ignore it.

Phishing attacks are a never-ending threat to online retailers, but by understanding how these scams work and setting up solid, layered prevention strategies, you can reduce your risk of falling victim to successful attacks. Building a vigilant team, investing in clear security protocols, and using the right technology are cornerstones of ecommerce phishing protection.

Start by teaching your team and creating a safe culture where security is everyone's responsibility. The more prepared you are, the tougher it will be for cybercriminals to find a way in.
