Report phishing defined as an attempt by an individual or group to solicit personal information from unsuspecting users by employing social engineering techniques, typically via emails containing links to fraudulent websites.

Report malware defined as malicious code (e.g., viruses, worms, bots) that disrupts service, steals sensitive information, gains access to private computer systems, etc.

Report software vulnerabilities or ICS vulnerabilities defined as defects that allow an attacker to violate an explicit (or implicit) security policy to achieve some impact (or consequence). In particular, defects that allow intruders to gain increased levels of access or interfere with the normal operation of systems are vulnerabilities. Insecure configurations, design choices, and changing environmental conditions can also cause vulnerabilities.

Report vulnerabilities in U.S. Government websites defined as defects that may allow an attacker to violate a security policy to cause some impact or consequence, particularly those vulnerabilities that allow increased levels of access or the ability to interfere with the normal operation of the server or site.
