What Is Phishing?
Phishing is a type of cyberattack in which criminals impersonate a trusted person, company, or organization to trick victims into revealing sensitive information, downloading malware, or sending money.
These attacks often appear to come from legitimate sources such as:
- Banks
- Microsoft 365
- Amazon
- Shipping companies
- Vendors
- Coworkers
- Executives
- Government agencies
The goal is to convince the recipient that the message is genuine before they have time to question it.
Because phishing attacks target people rather than technology, they’re among the most successful cyber threats facing businesses today.
Don't Let One Mistake Compromise Your Business
Phishing attacks are responsible for countless data breaches, financial losses, and compromised business accounts every year. While cybercriminals continue to develop more sophisticated techniques, most phishing attacks still rely on one simple tactic: convincing someone to trust a message that isn’t legitimate.
Whether it’s an email asking you to verify your password, a text claiming your package couldn’t be delivered, or someone impersonating your CEO requesting an urgent payment, phishing attacks are designed to trick people into taking actions that benefit the attacker.
Understanding what phishing is, how it works, and the different forms it can take is one of the best ways to protect your business from becoming the next victim.
Why Are Phishing Attacks So Successful?
Phishing works because it targets people rather than technology.
Attackers create messages that appear to come from trusted sources like:
- Microsoft
- Banks
- Shipping companies
- Coworkers
- Company executives
- Vendors
- Clients
These messages often create a sense of urgency by claiming:
- Your password has expired
- Your account has been compromised
- An invoice needs immediate payment
- A package couldn’t be delivered
- Payroll information needs updating
- Your Microsoft 365 account requires verification
When people feel pressured to act quickly, they’re more likely to overlook warning signs.
Spotting a Phishing Attempt
While phishing attempts continue to evolve, many still contain warning signs. One simple way to evaluate a suspicious email is to use the SLAM Method before clicking any links or downloading attachments.
S – Sender
Is the sender who they claim to be?
Check the sender’s email address or phone number carefully. Cybercriminals often use addresses that look legitimate at first glance, such as replacing letters with numbers or using a slightly different domain name.
Example:
- microsoft-support.com ❌
- microsoft.com ✅
L – Links
Hover over links before clicking.
Does the destination match the website you expect? If a link points somewhere unexpected or uses a shortened URL, don’t click it.
A – Attachments
Were you expecting this attachment?
Unexpected invoices, ZIP files, PDFs, or Office documents can contain malware or direct you to fraudulent login pages.
If you’re unsure, verify with the sender before opening anything.
M – Message
Does the message make sense?
Phishing emails often try to create panic or urgency with messages like:
- Your password has expired.
- Your Microsoft 365 account has been suspended.
- Your package couldn’t be delivered.
- An invoice is overdue.
- Update your payroll information immediately.
Also watch for:
- Poor grammar or awkward wording
- Generic greetings
- Requests for confidential information
- Pressure to act immediately
Even if an email passes one part of the SLAM Method, it’s still important to watch for common phishing indicators.
Look for:
- Unexpected requests for sensitive information
- Misspelled domain names
- Suspicious hyperlinks
- Unexpected attachments
- Generic greetings
- Poor grammar or awkward wording
- Urgent deadlines
- Requests for gift cards or wire transfers
- Login pages that don’t look quite right
If something feels unusual, don’t click. Verify the request through another communication method, such as calling the sender directly or starting a new email thread.
Common Types of Phishing Attacks
Not all phishing attacks look the same. Cybercriminals use different techniques depending on who they’re targeting and what they’re trying to accomplish.
Email Phishing: Traditional phishing emails are sent to large numbers of people in hopes that someone will click a malicious link or provide sensitive information.
Spear Phishing: Unlike mass phishing campaigns, spear phishing targets a specific individual or organization using personalized information to make the attack more convincing.
Whaling: Whaling targets executives and other high-level decision-makers who often have access to sensitive company information or financial resources.
Business Email Compromise (BEC): Business Email Compromise attacks involve criminals impersonating executives, employees, vendors, or clients to trick someone into sending money or sensitive information.
Smishing: Smishing uses text messages instead of email to trick users into clicking malicious links or sharing personal information.
Vishing: Vishing uses phone calls or voice messages to impersonate trusted organizations and manipulate victims into providing confidential information.
Quishing: Quishing is a newer phishing technique that uses malicious QR codes to direct victims to fraudulent websites or login pages.
What Happens If Someone Falls for a Phishing Attack?
A successful phishing attack can have serious consequences for a business.
Potential impacts include:
- Financial fraud
- Stolen credentials
- Unauthorized account access
- Data breaches
- Identity theft
- Ransomware infections
- Business disruption
- Compliance violations
- Reputational damage
In many cases, one compromised account can give attackers access to an entire business network.
How to Protect Your Business from Phishing
No single security measure can eliminate phishing attacks, but combining multiple layers of protection greatly reduces your risk.
Best practices include:
- Enable Multi-Factor Authentication (MFA)
- Provide ongoing employee cyber security training
- Use advanced email security solutions
- Verify unusual requests through another communication method
- Keep software updated
- Use strong, unique passwords
- Monitor suspicious login activity
- Report suspicious emails/texts immediately
Why Employee Training Is Your Best Defense
Technology can block many phishing attempts, but it can’t stop every one.
Employees remain one of the most important lines of defense against phishing attacks. Regular training helps staff recognize suspicious emails, verify unexpected requests, and report potential threats before they cause damage.
Organizations that invest in employee education are far less likely to experience successful phishing attacks.
