The hacktivist group known as Anonymous claimed to have published email addresses and login credentials belonging to members of the Minneapolis police department.

According to cyber security expert Troy Hunt, the information was previously stolen in an older data breach. It appears that the Anonymous group repackaged the information.

Hunt explains that, in examining the data set, 689 email addresses exist. Some have multiple passwords associated with them; a red flag.

In addition, of the 689 leaked email addresses, 659 of them were already included within the Have I Been Pwned database. A substantial number of those email addresses appear to have come from a 2012 LinkedIn data breach.

“The conclusion I draw from this is that a huge amount of the data is coming from aggregated lists known to be in broad circulation.” Other pieces of evidence also support Hunt’s thinking.
