In the case of this Fortune 100 company, it was a vulnerability in an open source program called JBoss. They're taking advantage of known vulnerabilities that exist in certain platforms." That wasn't the case, however, with the Fortune 100 company, which suggests some ransomware outfits may be changing their attack strategy. That's less so in Canada (30 percent) and the United Kingdom (39 percent). Osterman found more than half the attacks in the United States (59 percent) and Germany (61 percent) originated through email, either through malicious attachments or links. According to the Osterman study, email is the top vector for spreading ransomware. An employee receives a legitimate-looking email and is instructed to click on a link in it to receive some additional information, or other benefit. One of the most common ways ransomware infects a system is through an ill-advised click. How did it do that? An executive at the company agreed to answer that question as long as his name and his company's identity remain anonymous for security reasons. In fact, it ignored the attackers entirely. So how do you defend against ransomware? One Fortune 100 company didn't pay ransom when it was recently attacked. It also found that 40 percent of the companies in its survey paid ransoms after they were victimized. It found that most ransom demands remain small potatoes for most companies-more than 80 percent faced demands from $1,000 to $10,000-but one percent of the extortionists asked for $150,000 or more. Of those attacked, a third lost revenue and 20 percent had to suspend business entirely after discovering the attack, noted the study, which surveyed 540 CIOs, CISOs and IT directors from companies with an average of 5,500 employees. A recent study by Osterman Research for Malwarebytes found that 40% of companies in the United Kingdom, United States, Canada and Germany have suffered from a ransomware attack in the last year. Ransomware began as small time larceny but it has expanded to threaten businesses of all sizes.
