This study presents the results from a survey of 14,994 Australian adult computer users conducted in June 2021.
Nearly five percent of all respondents had ever experienced ransomware victimisation, while two percent of respondents had experienced ransomware in the last 12 months.
Small to medium enterprise (SME) owners were twice as likely as other respondents to have been the victim of ransomware attacks in the past year and were more likely to have paid the ransom. The prevalence of ransomware victimisation varied according to the industry in which respondents were currently employed.
Most ransomware victims did not pay the ransom. The advice given to ransomware victims was identified as the most common reason for a respondent’s decision about whether or not to pay the ransom, particularly in the case of SME owners.
