Overall, the number of weekly attacks on businesses will rise to 925 in 2021, a 50 percent increase from 2020.

Cybersecurity firm Check Point Research has released new data from 2021 showing that its customers have seen a significant increase in weekly cyberattacks on corporate networks compared to 2020. The researchers attribute part of the increase, which was concentrated at the end of the year, to the Log4J vulnerability (Log4Shell) discovered in December. According to Check Point, 2021 was a record-breaking year for cyberattacks, and the Log4J vulnerability only made matters worse.

“Last year saw 50 percent more cyberattacks on corporate networks per week than in 2020 — a significant increase. The number of cyberattacks peaked towards the end of the year, largely due to attempts to exploit the Log4J vulnerability,” said Omer Dembinsky, data research manager at Check Point Software.

“New penetration techniques and evasion methods have made it much easier for hackers to achieve malicious intent. Of particular concern is that a number of key societal industries appear on the list of top-attacked industries. Education, government and healthcare made it into the top 5 most attacked industries globally.”

According to Check Point, the total number of weekly attacks on corporate networks increased by 50 percent in 2021 compared to 2020. With 925 weekly cyber attacks per company, an all-time high was also reached in the fourth quarter.
