These attacks are anything but surprising given the current sentiment towards government officials, Minneapolis, and the state of Minnesota following the death of George Floyd. Anonymous took similar actions following the shooting of Michael Brown in Ferguson, Missouri. There have been a number of people on social media who have been misrepresenting this attack by claiming that Anonymous has been silent for three years and that this is possibly the start of something larger. The account which originally posted the video threatening MPD had not posted for three years but many members of Anonymous have been active around the world over the past three years. Major events like this have a tendency to increase the activity from the hacktivist collective. It is likely that over the coming weeks, continued attempts at attacking government agencies, especially those involved with law enforcement, will be seen from the group and its supporters. The majority of the attacks are likely to be Distributed Denial of Service attacks (DDoS), while other attacks may result in website defacements. It is also not uncommon for government officials and members of law enforcement to be doxed, have their information published online, or for local and state government databases to be breached and dumped publicly online.
