2017 was widely billed as the year of ransomware, but cyberthreats have moved in a new direction this year, according to ISACA’s State of Cybersecurity 2018 research.
Results show that 50 percent of the 2,366 security leaders surveyed have seen an increase in cyberattack volumes relative to last year. In addition, 80 percent of respondents said they are likely or very likely to be attacked this year—a statistic that remains unchanged from last year’s study.
But despite an increase in cyberattacks generally, ransomware attacks are significantly declining. Last year, 62 percent of respondents experienced a ransomware attack, compared to 45 percent this year—a 17-point drop. This is likely because organizations are significantly better prepared after last year’s WannaCry and NotPetya attacks. Eighty-two percent of respondents said that their enterprises now have ransomware strategies in place and 78 percent said they have a formal process—up 25-points from last year.
While these findings are positive, the data show that ransomware attacks may have been displaced by cryptocurrency mining, which is becoming more frequent. Cryptocurrency mining malware can operate without direct access to the file system, making them harder to detect—and as the prices of cryptocurrencies increase, the economics of cryptocurrency mining malware becomes better for the attacker.
Additionally, the three most common attack vectors remain unchanged from last year: phishing, malware and social engineering.
Active Defense Strategies Are Highly Effective, But Underutilized
ISACA’s research also found that nearly 4 out of 10 respondents (39 percent) are not at all familiar or only slightly familiar with active defense strategies (e.g., honeypots and sinkholes). Of those who are familiar with active defense strategies, just over half are actually using them.
“This is a missed opportunity for security leaders and their organizations,” said Frank Downs, director of cybersecurity at ISACA. “ISACA’s research indicates that active defense strategies are one of the most effective countermeasures to cyberattacks. A full 87 percent of those who use them indicate that they were successful.”
The ISACA report suggests enterprises must be better prepared with focused attention on several areas, including:
- Investing in talent—With attacks still on the rise, enterprises must continue to invest in finding, retaining and training skilled cyber security professionals.
- Exploring further automation benefits—Enterprises should consider automation-driven strategies and tools for detection and to support recovery and response efforts.
- Ensuring appropriate investment in security controls—With attack vectors (phishing, malware and social engineering) minimally changing, existing control types are still valid and useful. Enterprise investment and attention to security controls should increase in line with the frequency of these attack vectors.
