Postal Service™ employees and contractors need to be aware of an advanced form of malware known as ransomware. Ransomware limits a user’s access to data, either by disabling their system screen or locking files, until the ransom, normally in the form of virtual currency is paid.
The CyberSafe at USPS® team suggests the following preventative measures to avoid an attack:
n Keep all files and software, specifically antivirus, up to date.
n Back up your data daily.
n Don’t fall for phishing attacks.
n Verify links are legitimate before clicking.
n Be aware of attachments which could contain malware.
If you believe your computer or device has been affected by ransomware, immediately:
n Stop using the infected device.
n Contact the Cybersecurity Operations Center at 866–877-7247.
n Report the incident to your manager or supervisor.
Remember: Don’t use the infected device unless instructed to do so by the Postal Service’s Computer Incident Response Team or the IT Help Desk.
For additional information on ransomware, go to the Monthly Awareness Campaigns page on Blue at blue.usps.gov/cyber/comms-2023-archive.htm#accordion1s9.
