SonicWall Cyber Threat Mid-Year Report 2022: Key Findings
As world events increasingly shape the cybersecurity landscape, our partners at Sonicwall have been tracking the shifting trends, targets and tactics seen during the first half of 2022. We’ve compiled the most critical findings in the mid-year update of the 2022 Sonicwall Cyber Threat Report, which offers organisations of all sizes the actionable threat intelligence needed to safeguard against an increasingly volatile global threat environment.
Malware Rises By 11% Globally
Despite reaching a seven-year low in 2021, malware volume was already beginning to rise in the second half – a trend that has continued into the first half of 2022. Buoyed by increases in both IoT malware and crypto-jacking, malware volume has reached 2.8 billion so far this year, representing an average of 8,240 attempts per customer.
While malware was up overall, in areas that already saw a lot of malware, the opposite held true: The U.S., U.K. and Germany saw malware fall 1%, 9% and 13%, respectively.
Ransomware Attacks Down 23%
While the past two years have seen a meteoric rise in ransomware, the first half of 2022 brought a long-awaited reversal, as global ransomware volume fell 23% year to date. The decrease was largely fueled by a lower volume in Q2 – particularly in June, when ransomware volume fell to its lowest point since July 2020.
While North America saw a 42% decrease in ransomware volume, this was partially offset by a 63% increase in Europe. This suggests that ransomware isn’t just falling, it may also be starting to shift course due to factors such as government sanctions, supply-chain deficiencies, a limited availability of needed infrastructure and increased attention from law enforcement and governing bodies.
RTDMI Detections Rise Dramatically
In the first half of 2022, SonicWall’s patented Real-Time Deep Memory Inspection (RTDMI) technology discovered 270,228 never-before-seen malware variants – representing a 45% increase over the first half of 2021 and an average of 1501 new variants per day.
RTDMI leverages machine learning to become increasingly efficient at recognising and mitigating cyberattacks never seen by anyone in the cybersecurity industry.
IoT Malware up 77%
As the number of IoT devices continues to come online, so does the amount of IoT malware. In the first half of 2022, global attack volume rose 77% to 57 million – the highest since SonicWall began tracking these attacks, just short of the 60.1 million hits recorded in all of 2021. While the U.S. already saw more IoT malware than any other country, attacks there rose a staggering 228% through to the end of June. Triple-digit increases were also seen in the U.K., where attacks spiked 134%, as well as across every industry SonicWall examined.
Encrypted Threats Shows Triple-Digit Increase
Encrypted threats jumped 132% year-to-date, with Q2 showing particularly strong increases: May 2022 was the second highest month SonicWall has ever recorded for malware over HTTPs. If this trend holds, 2022 could become the third year in a row to see triple-digit increases in encrypted threats. However, there were a few bright spots, such as the retail industry, which saw a 79% drop.
Cryptojacking Reaches Record High
Despite a precipitous drop in the price of cryptocurrency, global cryptojacking volume rose to 66.7 million in the first half of 2022 – up 30% over the first half of 2021. This sustained increase has now reached record proportions: Q1 saw more cryptojacking than any quarter since SonicWall began tracking and January set a new monthly record at 18.4 million. While increases in attack volume were widespread, some were hit harder than others – such as the finance industry, which saw an increase of 269%.
