Rethink security priorities

Trend Micro recently released its 2018 Security Roundup Report, which depicts a threat landscape that has evolved heavily through both approach and tactics. One shift in attacks that businesses should be aware of is the rapid growth of cryptocurrency mining, which increased 237%. Overall, attacks that capitalise on the human desire to respond to urgent requests from authority are on the rise, such as business email compromise (BEC) and phishing, with phishing URL detections having increased 269% compared to 2017.

“The changes across the threat landscape in 2018 reflect a change in cybercriminal’s mindset,” said Jon Clay, director of global threat communications for Trend Micro. “Today’s most prevalent attacks are targeted and well planned, as opposed to one-size-fits-all attacks of the past. Knowing this pattern, we’re developing products that can outsmart these attack methods and allow us to be one step ahead of the bad guys.”

The number of BEC attacks in 2018 increased by 28%. While these attacks are less frequent than phishing attacks, they are more sophisticated and take more careful planning for cybercriminals and they yield an average of $132 000 per attack. As these attacks contain no malware and go undetected by traditional security measures, companies need to increase their protection against these attacks with smart solutions that analyse the email writing style of key executives in order to identify whether the email may be fraudulent. Trend Micro’s Writing Style DNA does exactly that and effectively helps detect business email compromise (BEC) attacks.

Another area of change across the threat landscape in 2018 was seen in zero-day vulnerabilities. Trend Micro’s Zero Day Initiative (ZDI) bought and disclosed more vulnerabilities in 2018 than ever before, including 224% more industrial control system bugs. This is particularly significant for organisations that struggle to implement patches across their systems. While zero-day exploits are less and less common, known vulnerabilities were used to execute the largest attacks in 2018. These tactics rely on vulnerabilities that have had patches available for months, even years, yet remain exposed in corporate networks.

Another strong indicator of how the threat landscape is shifting can be seen in the types of threats that decline. Ransomware detections decreased by 91% compared to 2017, along with a 45% decrease in new ransomware families. This reinforces the shift in attack tactics, as ransomware does not require extensive planning, technical skills or ingenuity due to the large number of resources available for malicious hackers in the cybercriminal underground.
