Jacobs noted that the number of breaches attributed to hacktivists in 2012 did not change from 2011. For both years, hacktivists accounted for only 2 percent of breaches by attack volume.
“We have seen an increase in denial of service (DoS) attacks from hacktivists,” Jacobs said. “In this report, we focus specifically on data loss events, so a denial of service is not something that makes an impact on the report.”
