Ransomware attacks skyrocketed in H1 2021

In the first half (H1) of 2021, ransomware attacks skyrocketed, eclipsing the entire volume for 2020 in only six months, according to the mid-year update to the SonicWall report. In a new paradigm for cybercrime, SonicWall is analyzing how threat actors are using any means possible to further their malicious intents.

Ransomware attacks volume reaching 304.7 million worldwide in H1 2021

With high-profile attacks against established technology and infrastructure, ransomware is now more prevalent than ever. Through the first half of 2021, there was a global ransomware volume of 304.7 million, surpassing 2020’s full-year total (304.6 million) — a 151% year-to-date increase.

“In a year driven by anxiety and uncertainty, cybercriminals have continued to accelerate attacks against innocent people and vulnerable institutions,” said SonicWall President and CEO Bill Conner.

“This latest data shows that sophisticated threat actors are tirelessly adapting their tactics and embracing ransomware to reap financial gain and sow discord. With remote working still widespread, businesses continue to be highly exposed to risk, and criminals are acutely aware of uncertainty across the cyber landscape. It’s crucial that organizations move toward a modern Boundless Cybersecurity approach to protect against both known and unknown threats, particularly when everyone is more remote, more mobile and less secure than ever.”

Ransomware attacks running rampant in H1 2021

After posting record highs in both April and May, a new high of 78.4 million ransomware attacks in June 2021 alone was recorded. Ransomware volume showed massive year-to-date spikes in the U.S. (185%) and the U.K. (144%). Accounting for 64% of all recorded ransomware attacks, Ryuk, Cerber and SamSam were the top three ransomware families in the first half of the year.

The top five regions most impacted by ransomware in the first half of 2021 were the United States, United Kingdom, Germany, South Africa and Brazil. Across the U.S., the five hardest-hit states were Florida (111.1 million), New York (26.4 million), Idaho (20.5 million), Louisiana (8.8 million) and Rhode Island (8.8 million).
