How to Spot a Phishing Email and Combat Phishing Attacks

What is a Phishing Email?

A phishing email is a message that tries to make the recipient hand over access, money, or data. That is usually what shows up in the investigation. A user clicks a link, lands on a fake Microsoft 365 or banking page, enters credentials, and the account starts showing sign-ins from places that do not match the user’s normal activity. 

Most email scams lean on something ordinary. A password check. A shared document. An invoice. A message from the CEO asking finance to move quickly. The email may not contain malware at all, just a link and a fake login page. Once they get credentials, the attacker takes advantage of the compromised email account. They read emails, create forwarding rules, and then send more phishing from the account.

How Does a Phishing Attack Work?

A phishing attack tricks users through social engineering tactics to convince victims to send login credentials and sensitive data to the cybercriminal. Social engineering techniques involve threat actors embedding malicious links into emails, attaching infected files, and impersonating CEOs, among other activities. Cybercriminals will send emails from compromised accounts or spoofed emails so employees do not realize the message is a threat. Such behaviors can lead victims to trust the sender, thus opening files and downloads or messaging back sensitive information. Now, let’s discuss how to spot a phishing email.

How to Spot a Phishing Email? Phishing Red Flags

Most users do not identify a phishing email because they recognize a specific attack technique. They stop because something does not line up. An invoice arrives from a vendor they have never worked with. A password reset appears even though they never requested one. A suspicious email often creates a small inconsistency that becomes obvious once the recipient slows down and looks at the details.

First, check the sender address. A message may claim to come from Microsoft, DocuSign, a bank, or an internal employee, but the actual domain tells a different story. Sometimes it is a single extra character. Sometimes a letter has been swapped. Those small changes are easy to miss when the email is pushing for immediate action.

Urgent pressure shows up constantly in phishing scams. Account suspension warnings. Failed payment notifications. Messages claiming payroll information must be verified immediately. The objective is simple. Get the recipient moving before they start asking questions. 

Grammar and spelling are less useful indicators than they used to be. Plenty of modern phishing emails are well written. What stands out now is context. The request feels unusual. The conversation history does not make sense. A coworker suddenly asks for gift cards. A vendor sends new banking instructions without explanation. An email requests passwords, MFA codes, account numbers, or other information that legitimate organizations rarely collect through email. That is usually where the message starts falling apart.

What Is the Difference Between Phishing and Spam?

When comparing spam vs. phishing, the difference is intent. To separate them, ask what the sender wants after the message is opened. Phishing is trying to get access to something. Credentials. Payment information. Internal data. An account. Spam, on the other hand,  is usually just unwanted bulk email. Most of it is annoying rather than dangerous. The sender wants visibility, clicks, or traffic. A phishing email has a narrower objective and is built around getting the recipient to surrender account access, money, or sensitive information

What Is Trap Phishing and How Does It Work?

Trap phishing works by taking advantage of trust that already exists between two people. The email is not necessarily unexpected. It may arrive from a compromised account, appear inside an existing email thread, or reference a project the recipient is actively working on. Nothing immediately looks wrong. 

That is what makes these messages effective. The recipient thinks they are responding to someone they already know. A document review request gets approved. A shared link gets opened. Credentials are entered into a login page because the request appears legitimate. The email succeeds because it looks like it belongs in the inbox.

How Do I Spot a Fake DocuSign Email?

You can spot a fake DocuSign email by examining everything around the document request, not just the request itself. The branding may look correct. The logo may be correct. Even the wording can look identical to a legitimate notification.

The details usually give it away. A sender address that does not belong to DocuSign. A reply-to address pointing somewhere unrelated. A document link that leads to a credential prompt instead of a document. That pattern shows up constantly during investigations. Anyone trying to learn how to spot a DocuSign scam email should spend more time checking where the message wants them to go than reading what the message says.

How Can I Prevent a Phishing Email Attack?

It is better to focus on preventing phishing campaigns than stopping messages altogether, as there will always be new and emerging threats that the most recent, modern software will not recognize. Therefore, we have compiled a list of best practices for email security that we suggest you consider when implementing a protection plan to secure email on your server:

• Scan emails with suspicious subject lines and signatures for spelling and grammar errors that cybercriminals insert to get past spam filtering services.
• Inspect attachments to see if they harbor email viruses, malware, dangerous code, or phishing links that could all download your credentials and harm your server.
• Use a phishing link checker to verify a website's legitimacy before replying to messages asking for personal information.
• Enforce email security policies that require employees to implement strong passwords and Two-Factor or Multi-Factor Authentication (2FA/MFA) methods as frequently as possible wherever such are available.
• Contact senders to confirm that a suspicious message is not an email threat, rather than hitting reply on the email thread you are concerned about. Consider a phone call or starting a separate email thread with the contact to prevent contacting compromised email addresses
• Hold email security training sessions so your employees know how to prevent phishing attacks.

Blocking phishing emails is not a one-time project. Attack techniques change, and new phishing threats appear every day. Even organizations with solid security policies still need visibility into what is reaching users' inboxes. 

For many small and mid-sized organizations, that becomes a staffing problem as much as a technical one. Email security generates alerts, quarantined messages, user reports, and policy decisions that somebody has to review. Guardian Digital EnGarde Cloud Email Security is designed to reduce that workload by filtering malicious email before it reaches users and providing continuous monitoring of the email environment. Instead of relying entirely on internal staff to track phishing campaigns, suspicious attachments, and malicious links, organizations can use EnGarde and Guardian Digital's 24/7/365 monitoring services to help identify and stop threats before they reach employees.
