Mid-year Update to the 2022 SonicWall Cyber Threat Report
But in the first half of 2022, the patterns are also altering, aside from the targets.
5 Cyber Threat Landscape Trends
1. Rising Malware
There are very few universally relevant cyber threat trends, and the surge in malware is one of them. However, regions that often see heavy malware activity, such as the U.S., U.K., and Germany experienced drops, indicating that these global hotspots could be starting to change.
2. Ransomware Decreases by Nearly a Quarter
Although ransomware attacks have significantly increased over the last two years, they decreased by 23% in the first half of 2022. As Russian ransomware organizations struggle to maintain their prior pace in the face of the ongoing crisis with Ukraine, this long-awaited reversal appears to be mostly the product of geopolitical circumstances.
Unfortunately, due to the greater, ongoing global dynamics, this trend is not expected to last.
However, due to the shifting nature of ransomware, certain places are recording drastically different results than expected. While Europe had a 63% spike in attack volume, North America, which normally experiences the majority of ransomware attacks, saw a 42% decline in attack volume.
3. RTDMI Detections Increase
A 45% increase over the same time in 2021, SonicWall’s proprietary Real-Time Deep Memory Inspection™ (RTDMI) technology discovered 270,228 never-before-seen malware types in the first half of 2022.
This technology is a part of the Sonicwall Capture Advanced Threat Protection and uses machine learning to become very good at spotting new and sophisticated threats. It gets better every year as evidenced by the 2,079 percent increase in new variants discovered by RTDMI since it was first introduced in early 2018.
4. IoT Malware Goes Up by 77%
It’s hardly surprising that opportunistic hackers are increasingly turning to IoT malware attacks as more and more IoT devices come online. IoT malware volume has increased 77% to 57 million since the start of the year, which is more than at any other time since SonicWall started keeping track of these attacks and almost as many as were discovered in 2021 as a whole.
5. Encrypted Threats Show Triple-Digit Growth
Threats that are encrypted increased 132% in the first half of 2022 compared to the same period last year. Based on an exceptionally high number of attacks in Q2, which spiked in May to become the second-highest month for encrypted threat volume ever recorded by SonicWall, this was the case.
