Imagine a typical workday at an office, opening and skimming through email after email. On a particularly busy day, rather than reading every subject line carefully, an employee might click on a seemingly innocuous link such as “track your package” or “verify your email.” Suddenly, company computers begin to slow down. Some programs begin to lag or fail outright. Error messages blink across screens. These days, opening one compromised link can be all it takes to make a company vulnerable to a cyberattack, which can cripple an organization and cost thousands or millions of dollars to repair.
