More than one third of organisations worldwide have experienced a ransomware attack or breach that blocked access to systems or data in the previous 12 months.
And for those that fell victim to ransomware, it is not uncommon to have experienced multiple ransomware events, according to a new International Data Corporation (IDC) survey.
“Ransomware has become the enemy of the day; the threat that was first feared on Pennsylvania Avenue and subsequently detested on Wall Street is now the topic of conversation on Main Street,” says Frank Dickson, program vice-president: cybersecurity products at IDC. “As the greed of cybermiscreants has been fed, ransomware has evolved in sophistication, moving laterally, elevating privileges, actively evading detection, exfiltrating data, and leveraging multifaceted extortion. Welcome to digital transformation’s dark side.”
Key findings from the survey include the following:
* The incident rate was notably lower for companies based in the US (7%) compared to the worldwide rate (37%).
* The Manufacturing and Finance industries reported the highest ransomware incident rates while the Transportation, Communication, and Utilities/Media industries reported the lowest rates.
* Only 13% of organisations reported experiencing a ransomware attack/breach and not paying a ransom.
* While the average ransom payment was almost a quarter million dollars, a few large ransom payments (more than $1-million) skewed the average.
Greater awareness of ransomware incidents has prompted organisations to undertake a variety of actions in response. These include reviewing and certifying security and data protection/recovery practices with partners and suppliers; periodically stress-testing cyber response procedures; and increased sharing of threat intelligence with other organisations and/or government agencies. Greater incident awareness has similarly prompted requests from boards of directors to review security practices and ransomware response procedures.
Analysis of the survey results also showed that organisations that are further along in their digital transformation (DX) efforts were less likely to have experienced a ransomware event. These are organizations that have committed to a long-term DX investment plan with a multi-year approach tied to enterprise strategy.
