The BBC reported that as the United States deals with widespread civil unrest across dozens of cities, "hacktivist" group Anonymous has returned from the shadows. The hacker collective was once a regular fixture in the news, targeting those it accused of injustice with cyber-attacks. After years of relative quiet, it appears to have re-emerged in the wake of violent protests in Minneapolis over the death of George Floyd, promising to expose the "many crimes" of the city's police to the world. However, it's not easy to pin down what, if anything, is genuinely the mysterious group's work.
Various forms of cyber-attack are being attributed to Anonymous in relation to the George Floyd protests. First, the Minneapolis police department website was temporarily taken offline over the weekend in a suspected Distributed Denial of Service (DDoS) attack. This is an unsophisticated but effective form of cyber-attack that floods a server with data until it can't keep up and stops working -- in the same way that shopping websites can go offline when too many people flood it to snap up high-demand products. A database of email addresses and passwords claiming to be hacked from the police department's system is also in circulation, and being linked to Anonymous. However, there is no evidence that the police servers have been hacked and one researcher, Troy Hunt, says the credentials are likely to have been compiled from older data breaches.
A page on the website of a minor United Nations agency has been turned into a memorial for Mr Floyd, replacing its contents with the message "Rest in Power, George Floyd", along with an Anonymous logo. On Twitter, unverified posts have also gone viral, apparently showing police radios playing music and preventing communication. However, experts suggest it is unlikely to be a hack, and could instead be the result of a stolen piece of hardware being commandeered by protesters on the scene -- if the videos are genuine in the first place. Anonymous activists are also circulating years-old accusations against President Trump, taken from documents in a civil court case that was voluntarily dismissed by the accuser before it went to trial.
