Learn how phishers target employees and how to spot a scam.
Social engineering isn’t always done in person; sometimes all it takes is for a single malware-infected email to cause havoc on a business’s entire network. That’s why phishing attacks are often so effective.
Here are a few things you should know about these types of attacks.
What is phishing?Phishing refers to a type of social engineering that happens primarily through emails. Hackers will send emails that often have links to malware.
The reason why phishing is effective is because it targets a big weakness in security: people. The best firewall in the world can’t help against an employee clicking on a malware-loaded email. Once one computer gets infected, if that computer is connected to the businesses network, the malware can spread throughout the entire network. It becomes even more dangerous when it spreads to computers with sensitive data.
For some businesses, all it takes is one infected computer to bring down an entire network.

Common phishing tacticsSo what phishing methodologies are put to use?
How do phishers target your employees?
- Impersonation: A phisher may impersonate a higher-up, asking an employee for sensitive information/credentials, or ask the employee to wire money
- Contest winner: If you get an email claiming you won something you never even entered, it’s highly likely the email is a phishing scam
- The victim: This type of phishing email acts as an angry customer who supposedly sent you money in return for a shipped product. The email concludes with the threat that they will inform the authorities if they don’t hear from you
- False bank notification: This ploy tricks you with a fake account notification, stating that an amount has been withdrawn from your account that exceeds your notification limit. It often gives you a convenient link that leads to a web form asking for your bank account number “for verification purposes”

How to spot a phishing emailSo, you’ve received an email that seems a little strange. How do you know if it’s a phishing scam? Here are a few questions to ask.
When was it sent?
Was it scheduled at a random time, such as 3 in the morning? Did you receive the email during business hours?
Do you know the sender?
If you’ve never heard of the sender or had any previous contact with them, it could be an indication of a scam, especially if they claim to know you.
Are the URLs slightly different?
Some phishers create domains to mimic larger, more established organizations. For example by adding an extra number like www.2target.com or www.bestbuy1.com, it may thwart the busied user into clicking a malicious link.
Does the content not match the subject?
This is a big red flag. If the subject line doesn’t match the content in the email, it’s a good indicator that the email might be a scam.
How is the grammar/spelling?
Does the email appear to have really bad grammar? Are many words misspelled? These could be indications of a scam.
As a basic rule of thumb, if something seems weird about an email, do not click on the link it offers or download anything. It’s better to be cautious than to risk infecting your entire business network.
If you see a phishing email, take the following steps:
- Don’t click on any links or open attachments
- Don’t try to reply to the sender
- Report the scam (forward the e-mail to FTCfirstname.lastname@example.org)
- Delete the email from your computer
- If you do business with a company mentioned in the email, you may want to call them and ask if they would like you to forward the email to them, so they may take further action
