Manufacturing and energy became the second and third most targeted industries last year, respectively. Retail and professional services rounded up the top five most targeted sectors, IBM says.

In the latest installment of their annual X-Force Threat Intelligence Index, IBM Security also reveals that ransomware was the most popular attack method in 2020, with a market share of roughly 23%.

“Threat actors carried out ransomware attacks predominantly by gaining access to victim environments via remote desktop protocol, credential theft, or phishing—attack vectors that have been similarly exploited to install ransomware in prior years,” IBM explains.
