SonicWall Capture Labs threat researchers unveil third-quarter threat intelligence

SonicWall Capture Labs threat researchers today unveiled third-quarter threat intelligence collected by the company’s more than 1 million global security sensors. The findings highlight cybercriminal’s growing use of ransomware, encrypted threats and attacks leveraging non-standard ports, while overall malware volume declined for the third consecutive quarter.

“For most of us, 2020 has been the year where we’ve seen economies almost stop, morning commutes end and traditional offices disappear,” said SonicWall President and CEO Bill Conner. “However, the overnight emergence of remote workforces and virtual offices has given cybercriminals new and attractive vectors to exploit. These findings show their relentless pursuit to obtain what is not rightfully theirs for monetary gain, economic dominance and global recognition.”

SonicWall Capture Labs key findings include:
• 39% decline in malware (4.4 billion YTD); volume down for the third consecutive quarter
• 40% surge in global ransomware (199.7 million)
• 19% increase in intrusion attempts (3.5 trillion)
• 30% rise in IoT malware (32.4 million)
• 3% growth of encrypted threats (3.2 million)
• 2% increase in cryptojacking (57.9 million)

SonicWall research concludes that overall global malware volume continues steadily decline in 2020. In a year-over-year comparison through the third quarter, SonicWall researchers recorded 4.4 billion malware attacks — a 39% drop worldwide.

Regional comparisons show India (-68%) and Germany (-64%) have once again seen a considerable drop-rate percentage, as well as the United States (-33%) and the United Kingdom (-44%).

SonicWall researchers tracked aggressive growth during each month of Q3, including a massive spike in September. While sensors in India (-29%), the U.K. (-32%) and Germany (-86%) recorded decreases, the U.S. saw a staggering 145.2 million ransomware hits — a 139% YoY increase.

Notably, SonicWall researchers observed a significant increase in Ryuk ransomware detections in 2020. Through Q3 2019, SonicWall detected just 5,123 Ryuk attacks. Through Q3 2020, SonicWall detected 67.3 million Ryuk attacks — a third (33.7%) of all ransomware attacks this year.

COVID-19 led to an unexpected flood of devices on networks, resulting in an increase of potential threats to companies fighting to remain operational during the pandemic. SonicWall Capture Labs found a 30% increase in IoT malware attacks, a total of 32.4 million worldwide.

Most IoT devices — including voice-activated smart devices, door chimes, TV cameras and appliances — were not designed with security as a top priority, making them susceptible to attack and supplying perpetrators with numerous entry points.
SonicWall threat intelligence data also concluded that while cryptojacking (57.9 million), intrusion attempts (3.5 trillion) and IoT malware threats (32.4 million) are trending with first-half volume reports, they continue to pose a threat and remain a source of opportunity for cybercriminals.
