The Postal Service is reminding employees and contractors to stay alert to ransomware — software that blocks access to computers or other devices until a ransom is paid.
This type of malware can severely affect USPS operations.
Cybercriminals often spread ransomware through phishing emails, suspicious links, malicious attachments, compromised websites or unauthorized USB devices.
Here are some tips to avoid a ransomware attack:
• Keep software, operating systems and antivirus tools up to date.
• Be cautious of unexpected emails, links, QR codes and attachments.
• Verify the sender of an email before clicking on links or responding.
• Back up important files regularly.
• Don’t insert unauthorized USB drives or external storage drives into USPS equipment.
If you think your device may be infected with ransomware, stop using it immediately, disconnect it from the Postal Service network, if possible, and contact the Cybersecurity Operations Center at 866-877-7247. Then report the incident to your manager or supervisor.
