A cybersecurity threat is anything that can exploit a vulnerability to negatively impact your digital systems, networks, data and people. It may take the form of malware, phishing, ransomware or other cyberattacks.
Cyber threats can result in financial loss, identity theft, data breaches or disruption of services. They can also have broader economic effects by hurting trust in digital transactions, depriving companies of needed resources or even jeopardizing their solvency. As a result, they cost billions each year in damages worldwide.
Attackers constantly find new opportunities to exploit vulnerabilities and infiltrate organizations’ computer systems, networks and data. For example, poorly secured Internet of Things (IoT) devices like thermostats and smoke detectors give attackers a pathway into an organization’s network. And the rapid growth of AI technologies, OT and the cloud give attackers new tools to use in attacks.
Most cyberattacks are driven by a desire to make money or steal data. They can steal money directly, such as credit card or personal information, or they can extort it for ransom. Some attackers seek data in the form of intellectual property or source code, and some are after a mix of both.
Almost all modern cyberattacks involve some type of malware. Hackers and criminals create malware to gain unauthorized access to computers, steal sensitive data or hijack computer systems to operate them remotely. The best way to protect against malware is to use strong passwords, keep software updated and be vigilant when browsing the web or responding to emails. It is also important to conduct regular employee training and awareness sessions on how to identify suspicious activity. Finally, implementing security measures such as network segmentation and detection and response systems can help to contain a breach.
