Ransomware attacks spiked dramatically in the U.S. in the first half of 2020 but malware incidents worldwide dropped noticeably, a new SonicWall threat report said.
The period also saw cyber crews opportunistically exploit the coronavirus (COVID-19) pandemic, systemic weaknesses and a growing reliance on Microsoft Office files by cyber criminals, SonicWall said in its newly released 2020 Cyber Threat Report. Global malware attacks fell from 4.8 billion to 3.2 billion (-24%) over 2019’s mid-year total and follows a downward trend that began last November, the security specialist said. While the tumbling number of malware attacks in the U.S. (-24%) is noteworthy, it is less of a dip than in the United Kingdom (-27%), Germany (-60%) and India (-64%), the report said.
As global malware assaults slowed, ransomware incidents worldwide climbed by 20 percent to 121.4 million events during the six-month period, according to SonicWall’s data.
Here are some additional findings:
In these uncharted times, organizations must shift from “makeshift or traditional security strategies” to a new business model that is “no longer new,” said Bill Conner, SonicWall president and chief executive. “Cyber criminals can be resourceful, often setting traps to take advantage of people’s kindness during a natural disaster, panic throughout a crisis and trust in systems used in everyday life,” he said.
Cyber gangs capitalize in uncertain times by adapting their tactics to “sway the odds in their favor,“ Conner said. “With everyone more remote and mobile than ever before, businesses are highly exposed and the cyber criminal industry is very aware of that.”
Here are some additional details from the report:
On ransomware.
On COVID-19 malware.
On Microsoft Office.
On malware spread.
On attack vectors.
On IoT threats.
“Cybercriminals are too sophisticated to use known malware variants, so they’re re-imagining and re-writing malware to defeat security controls like traditional sandboxing techniques — and it’s working,” said Conner.
