Hackers use "anti-work" manifesto to send spam to the company's receipt printer

According to people who claim to have seen the printed manifesto, dozens of posts on Reddit, and a cybersecurity company that is analyzing the network traffic of unsecured printers, one or more people are hyping “anti-work” to the receipt printers of businesses around the world. declaration.
“Is your salary low?” According to several screenshots posted on Reddit and Twitter, one of the declarations was read.”You have the protected legal right to discuss your salary with colleagues. [...] Poverty wages exist only because people are’willing’ to work for them.”
On Tuesday, a Reddit user wrote in a post that the manifesto was randomly printed during his work.
“Which one of you did it because it was fun,” the user wrote.”My colleagues and I need answers.”
There are countless similar posts on the r/Antiwork subreddit, some of which have the same manifesto.Others have different information, but the same views on empowering workers.Readers of all these messages are advised to check out the r/antiwork subreddit. As workers begin to demand their own value and organize against workplace abuse of power, its scale and influence have exploded in the past few months.
“Stop using my receipt printer. It’s funny, but I want it to stop,” read a post on Reddit.Another wrote: “During my work in the past week, I have received about 4 different messages at random. It was very inspiring, inspiring, and very inspiring to see that my boss had to tear their faces off the printer. interesting.”
Some people on Reddit believe that these messages are fake (that is, printed by someone who can use a receipt printer and posted to people with influence on Reddit) or as part of a conspiracy to make r/antiwork subreddit look like they are doing something illegal matter.
However, Andrew Morris, the founder of GreyNoise, a cyber security company that monitors the Internet, told Motherboard that his company has seen actual network traffic flowing to insecure receipt printers, and it seems that one or more people are sending it over the Internet. These print jobs are indiscriminately, like spraying or blasting them.Morris has a history of catching hackers using unsafe printers.
“Someone is using a technology similar to’mass scan’ to send raw TCP data directly to the printer service on a large scale via the Internet,” Morris told Motherboard in an online chat.”Basically every device that opens the TCP 9100 port and prints a pre-written document that quotes /r/antiwork and some workers’ rights/anti-capitalist messages.”
“One or more people behind this are distributing a large amount of printed material from 25 independent servers, so blocking just one IP is not enough,” he said.
“A technician is broadcasting a print request of a document containing workers’ rights messages to all printers that have been misconfigured to be exposed on the Internet. We have confirmed that it was successfully printed in some places. The exact number is difficult to confirm, but Shodan said, Thousands of printers have been exposed,” he added, referring to Shodan, a tool that scans the Internet for unsafe computers, servers and other devices.
Hackers have a long history of using unsafe printers.In fact, this is a classic hacker.A few years ago, a hacker asked the printer to print out promotional information for the controversial PewDiePie YouTube channel.In 2017, another hacker asked the printer to spit out a message, boasting and calling himself “the god of hackers.”
