Most reports on data theft events concentrate on how the bad guys got into the organization, what failed to stop them, and what information was taken. I often think about how the information was taken out, or exfiltrated, and who the likely #culprits were.
#intel Security recently published a research study that addresses these questions. The most likely thieves are organized crime, hacktivists, and nation states, although #insiders are accomplices in about 40% of the thefts, according to the study. When insiders were involved, including employees, contractors, and third-party suppliers, half of the #breaches were intentional and the other half accidental.
