Malware can cause widespread damage to the USPS network and compromise postal information.

It’s important to recognize the signs of malicious software — including computer viruses, Trojans and wormswhen operating Postal Service computers and devices.

These infections, also known as malware, can cause widespread damage to the USPS network and compromise Postal Service information.

Here are common signs of malware infections:

  • Files or data suddenly become unavailable.
  • Files have been edited when no changes should have occurred.
  • Files appear, disappear or undergo unexpected changes in storage size.
  • Systems display strange messages or mislabel files.
  • Systems or applications become slow, unstable or inaccessible.
  • Unexpected processes occur, such as your email program starting on its own.

If you believe your computer or device has been infected by malware, stop working on the computer or device immediately.

Call the Computer Incident Response Team at 866-877-7247 or send an email to CyberSafe@usps.gov to report the incident.

The CyberSafe at USPS Blue site has more information and security guidance.
