Be wary of criminals posing as colleagues

Some cybercriminals pose as USPS personnel, using fraudulent emails, texts or phone calls to attack the Postal Service’s network.

The Postal Service is reminding employees and contractors to be aware of cybercriminals impersonating USPS personnel.

These cybercriminals use fraudulent emails (phishing), text messages (smishing) or phone calls (vishing) to carry out their attacks.

To protect yourself and the organization, follow these tips:

Be suspicious: Always be wary of any email, text message or phone call that requests personal information or urges you to take immediate action.

• Don’t click on links: Avoid clicking on links in unexpected or unsolicited emails or text messages. If you believe the email or text message could be legitimate, look up the individual’s or company’s contact information and reach out to them directly for verification.

• Verify the sender: Be cautious of text messages from unknown numbers or numbers that don’t look like phone numbers. Scammers often use email-to-text technologies to disguise their real phone numbers.

Don’t reply: If you receive a suspicious email, text message or phone call, don’t reply or respond.

If you believe you are the victim of one of these attacks, call the Cybersecurity Operations Center at 866-877-7247 or send an email to
