Recently, hackers successfully targeted the country’s largest fuel pipeline, the world’s largest meat processor and the New York City transit system. One company even paid the hackers nearly $5 million to recover its stolen data. In the wake of these cyberattacks, the White house warned companies to increase their cybersecurity and formed a Department of Justice task force, which was able to recapture that ransom money. DU cybersecurity professor Nate Evans discusses what makes a company vulnerable to an attack, how companies weigh the decision to pay ransom and why we are seeing a spike in cyberattacks now.
