The Public Administration sector accounted for a large number of security incidents but a relatively small number of data breaches, since they were run of the mill malware infections or minor policy violations that don’t compromise confidential data.
Ransomware: a perennial threat
Ransomware attacks are by far the most common, accounting for 61% of malware cases. The malware is most commonly downloaded either by other malware, or is directly installed by the attacker after gaining access. An attack is considered an integrity breach when the software is installed, and becomes an availability breach when the victim’s system is encrypted.
Small mistakes can mean big consequences
The most common errors in this sector happened through two types of breaches—Misdelivery, when mass emails or paper mailings are sent to the wrong recipients, or through Misconfiguration, when someone puts data in the cloud without appropriate security measures.
A change in attack patterns
After Miscellaneous Errors like Misconfigurations and Misdeliveries, the next top patterns this year were Web Application attacks and the “Everything Else” pattern—which includes attacks that don’t fit within other categories. Encouragingly, two of last year’s top patterns, Cyber-Espionage and Privilege Misuse, both saw decreases.
