In April this year, IDT, a Newark, New Jersey-based telecommunications company, suffered a similar attack, which was discovered by Goran Ben-Oni, the company's global chief operating officer. As Ben Oni said in an interview with the New York Times, he immediately realized that this blackmail software attack is different from other attacks against companies. It not only steals the information in the databases it infiltrates, but also steals the information needed to access these databases. This kind of attack means that hackers can not only obtain this information quietly, but also continuously monitor who accesses this information.
