Large Scale Ransomware Attacks

The ransomware threat is on the rise as almost 40% of businesses reported an attack in the previous year according to a recent survey.

Security firm Malwarebytes surveyed companies and found one-third of victims lost revenue as a result of a ransomware attack. It’s the downtime caused by the ransomware rather than the cost of paying the ransom that does the most damage to a business.

Malwarebytes™ (software company selling anti-malware products) released its “Second Annual State of Ransomware Report”. The multi-country study surveyed 1,054 companies with no more than 1,000 employees across North America, France, U.K., Germany, Australia, and Singapore. More than one-third of businesses have experienced a ransomware attack in the last year. Twenty-two percent of these impacted businesses ceased operations immediately.

Key Findings

“Businesses of all sizes are increasingly at risk for ransomware attacks,” said Marcin Kleczynski, CEO, Malwarebytes. “However, the stakes of a single attack for a small business are far different from the stakes of a single attack for a large enterprise.

The impact of ransomware on SMBs can be devastating. For roughly one in six impacted organizations, a ransomware infection caused 25 or more hours of downtime, with some organizations reporting that it caused systems to be down for more than 100 hours. Further, among SMBs that experienced a ransomware attack, 22 percent reported that they had to cease business operations immediately, and 15 percent lost revenue.

The most common source of ransomware infections is via email – links to scammer websites or malware loaded attachments.

Seventy-two percent of respondents believe that ransomware demands should never be paid. Most of the remaining organizations believe that demands should only be paid if the encrypted data is of value to the organization. Among organizations that chose not to pay cybercriminals’ ransom demands, about one-third lost files as a result.

“Companies of all sizes need to remain vigilant and continue to place a higher priority on protecting themselves against ransomware.”
