Safety tips for personal devices

Unauthorized devices
Plugging unauthorized devices into USPS equipment could unleash malware into the network.

The Postal Service is reminding employees that plugging smartphones, unapproved thumb drives, e-cigarettes and other personal devices into USPS computers violates the organization’s security policies.

Plugging unauthorized devices into postal equipment runs the risk of inadvertently transferring malicious software, which could disable computers and allow hackers to gain access to the organization’s network.

To protect your devices and the network, the CyberSafe at USPS team suggests the following tips:

• Plug only USPS-approved devices into postal equipment. A list is available on Blue.

• Use a wall outlet to charge your personal devices. You can also use a portable charger.

• Avoid public charging stations. Cybercriminals sometimes install malicious software in these stations to gain access to personal data stored on devices.

• Report unauthorized devices. If you see an unauthorized device plugged into a postal computer’s USB port, notify the device owner or a supervisor.
