A cybersecurity threat is a potential danger to information systems that could result in theft, exposure, or damage. Attacks are typically launched by cybercriminals seeking financial gain, but can also be committed by disgruntled employees or individuals who just like the intellectual challenge of hacking. It is important to note that not all hackers have ill intentions, some are known as white-hat hackers and engage in ethical activities such as testing the security of systems.
There are a variety of different types of cyberattacks including viruses, spyware, worms, Trojans, ransomware, denial-of-service attacks, and breaches. Many of these threats are delivered through phishing emails or USB drives and use vulnerabilities to access devices and steal data. Spyware monitors activity without user consent, while worms exploit system backdoors and carry out attacks such as distributed denial of service (DDoS). Trojans blend in seamlessly with apps sold on official app stores and allow attackers to hijack devices by remotely controlling their behavior.
The threat landscape is rapidly evolving and becoming increasingly complex. With innovation, hyper-connectivity, and digital dependency far outpacing cyber defenses, the risk of a “cyber 9/11” is real and the consequences could be devastating.
In addition to stealing critical data and intellectual property, cyberattacks are costing organizations money through the loss of revenue, operational efficiency, and brand reputation. They can even cause physical damage, as in the case of the Colonial Pipeline ransomware attack which caused a shutdown of the company’s pipeline that carries gasoline and diesel to New York City.
