Hackers are increasingly using malicious software to gain unauthorized access to computers, networks and systems.
Cybercriminals recently launched a global ransomware attack to extort funds from companies in more than 60 countries.
To prevent attacks, the Postal Service reminds employees to follow these guidelines:
• Keep anti-virus software updated. Employees with USPS equipment should connect to the intranet every week to receive software updates, a requirement explained in Handbook AS-805-C: Information Security Requirements for All Personnel.
• Scrutinize all emails and online sites. Think before visiting sites, clicking on links or opening email attachments. Hackers often use phishing emails, such as the recent Google Docs scam, to con users into downloading malicious software.
• Be skeptical. Beware of software companies that claim to have detected a virus on your device. Hackers often use this ploy to steal passwords and gain control of devices.
If you suspect your USPS equipment has been targeted by hackers or infected with malware, report it immediately to the CyberSecurity Operations Center at firstname.lastname@example.org.
