Cybercriminals attacked with gusto in the first half of 2021 and attacks show no signs of slowing down. In just the first half of the year, malicious actors exploited dangerous vulnerabilities across different types of devices and operating systems, leading to major attacks that shut down fuel networks and extracted millions from enterprises.
These were among the results of a midyear security roundup from Trend Micro, which detected 7.3 million ransomware threats in the first six months of 2021. Despite the high-profile coverage ransomware has so far received, detections actually decreased by 50% year-over-year.
However, the attacks that occurred in the first half of 2021 were highly sophisticated, targeted and complex, making them more detrimental to victims.
