Business email compromise (BEC) has cost companies $3.1 billion since January 2015 and consumer email phishing is at an all-time high. Most people don’t question the “from” field in the emails they get day in and day out, yet without the right tools in place, there’s actually no reason to trust the “from” field!
Unfortunately though, no matter how sophisticated a company or enterprise’s email strategy is, some phishing emails will always make it to the inbox. And these messages are extremely effective. Verizon found that 30% of targeted recipients open phishing messages and 12% click on malicious email attachments.
As a critical piece of every business’ email security strategy must be education, below are Proofpoint’s top 10 tips for identifying a phishing email.
Tip 1: Don’t trust the display name
A favorite phishing tactic among cybercriminals is to spoof the display name of an email. Here’s how it works: If a fraudster wanted to impersonate the hypothetical brand “My Bank,” the email may look something like:
Once delivered, the email appears legitimate because most user inboxes and mobile phones will only present the display name. Always check the email address in the header from—if looks suspicious, flag the email.
Tip 2: Look but don’t click
Cybercriminals love to embed malicious links in legitimate-sounding copy. Hover your mouse over any links you find embedded in the body of your email. If the link address looks weird, don’t click on it. If you have any reservations about the link, send the email directly to your security team.
Tip 3: Check for spelling mistakes
Brands are pretty serious about email. Legitimate messages usually do not have major spelling mistakes or poor grammar. Read your emails carefully and report anything that seems suspicious.
Tip 4: Analyse the salutation
Is the email addressed to a vague “Valued Customer?” If so, watch out—legitimate businesses will often use a personal salutation with your first and last name.
Tip 5: Don’t give up personal or company confidential information
Most companies will never ask for personal credentials via email–especially banks. Likewise most companies will have policies in place preventing external communications of business IP. Stop yourself before revealing any confidential information over email.
Tip 6: Beware of urgent or threatening language in the subject line
Invoking a sense of urgency or fear is a common phishing tactic. Beware of subject lines that claim your “account has been suspended” or ask you to action an “urgent payment request.”
Tip 7: Review the signature
Lack of details about the signer or how you can contact a company strongly suggests a phish. Legitimate businesses always provide contact details. Check for them!
Tip 8: Don’t click on attachments
Including malicious attachments that contain viruses and malware is a common phishing tactic. Malware can damage files on your computer, steal your passwords or spy on you without your knowledge. Don’t open any email attachments you weren’t expecting.
Tip 9: Don’t trust the header from email address
Fraudsters not only spoof brands in the display name, but also spoof brands in the header from email address, including the domain name. Keep in mind that just because the sender’s email address looks legitimate (e.g [email protected]), it may not be. A familiar name in your inbox isn’t always who you think it is!
Tip 10: Don’t believe everything you see
Phishers are extremely good at what they do. Many malicious emails include convincing brand logos, language, and a seemingly valid email address. Be skeptical when it comes to your email messages—if it looks even remotely suspicious, do not open it.
