Disconnect to Protect!
Hackers these days use a variety of techniques to infiltrate networks, systems, and devices to steal your information, or even your identity. Targets include all mobile devices, such as phones, tablets, fitness trackers, or other Wi-Fi and Bluetooth-enabled devices, or devices that use a USB cable.
Hackers target mobile devices with malicious text messages, voicemails, and fake downloads or applications. If you receive a text message or voicemail from an unknown person or organization that asks you to click on a link or provide account information, delete it immediately and report the incident to the CyberSecurity Operations Center (CSOC) at email@example.com if using a Postal Service™ device.
Protect your mobile devices against potential cyber threats using these tips:
- Watch out for suspicious messages. Don’t open links or attachments sent via text messages or emails from people you do not know.
- Stay up to date. Regularly update your operating system and security software on all of your mobile devices. Do not download applications from unknown or disreputable sources. Only download USPS-approved updates on Postal Service devices.
- Connect selectively. Disable your Wi-Fi and/or Bluetooth when not in use. Additionally, do not use public Wi-Fi networks unless you have submitted an electronic request for computer access through a VPN. Avoid logging into accounts with personal information, such as your email or banking websites.
- Never plug personal devices into a Postal Service network or computer. Similarly, do not plug USPS-issued devices into other computer equipment. Even if the device does not have internet access or access to the Postal Service intranet, connecting your device still poses the risk of a cyber breach. If you need to charge your device, always use an outlet in an approved area.
When employees properly report suspicious activity, the Postal Service can step in to combat the threat, protect its network, and prevent other employees from being compromised. If you notice any suspicious activity, report it immediately to the CSOC (firstname.lastname@example.org).
