Mitigating malicious cyber activity comes in different forms, ranging from identifying and removing malware or a malicious browser extension on your device, to policies requiring disclosures of software vulnerabilities, to interviewing stakeholders to assess cybersecurity posture, and international actions involving treaties and law enforcement. Those efforts can result in the arrest of cybercriminals, to disrupting infrastructure used by cybercriminals and degrading their ability to carry out cyber-attacks, all the way down to blocking malicious software or extensions, all in an effort to prevent the compromise of computer networks, and loss of sensitive data.
