According to a report by Vice and a post on Reddit, hackers are attacking business receipt printers to insert pro-labor information.”Are you underpaid?”, read one message, “How can McDonald’s in Denmark pay employees $22 an hour for $22 an hour and still sell a Big Mac for less than the U.S.?” Another State.
Many similar images have been posted on Reddit, Twitter and elsewhere.Information varies, but most readers point to the r/antiwork subreddit, which has recently become popular during the COVID-19 pandemic, as workers start demanding more rights.
Some users believed the information was fake, but a cybersecurity firm that monitors the internet told Vice it was legitimate.GreyNoise founder Andrew Morris told Vice: “Someone… sends raw TCP data directly to a printer service on the Internet.” “Basically every device opens TCP port 9100 and prints [ing] a pre-written document. , which cites /r/antiwork and some worker rights/anti-capitalism news.”
According to Morris, the individuals behind the attack used 25 separate servers, so blocking one IP won’t necessarily stop the attack.”A technician is broadcasting a print request for a document containing worker rights messages to all printers that are misconfigured to be exposed on the Internet, and we’ve confirmed that it prints successfully in some places,” he said.
Printers and other internet-connected devices can be notoriously insecure.In 2018, a hacker hijacked 50,000 printers and sent out a message telling people to subscribe to PewDiePie, all at random.In contrast, receipt printer hackers have a more focused set of targets and messages.
