Hacker 'Stackoverflowin' highlights vulnerabilities in networked printers by taking over 150,000 devices and printing out a security alert.
As 'derStandard' and 'Futurezone' report, a hacker named 'Stackoverflowin' managed to make 150,000 networked printers dance to his tune.
According to 'Bleeping Computer', he said he took over the internet-enabled devices to draw attention to a problem that many companies and private individuals are not aware of:
Unprotected printers can receive third-party print jobs online.
In March 2016, the hacker 'Weev' sent anti-Semitic messages in this way, which were printed out by the recipients.
“Pay better attention to safety”
'Stackoverflowin' used this vulnerability to draw attention to this issue.
His message included a call to pay better attention to safety.

How did he do that?
The hacker ran a script for 24 hours that searched for unprotected printers. It ranges from large multifunction printers to small receipt printers.
The script addressed those devices that keep IPP (Internet Printing Protocol) ports, LPD (Line Printer Daemon) ports and port 9100 open for external connections.
In addition, he had exploited an exploit that affected Dell Xeon printers.
Models from the manufacturers Brother, Canon, Epson, HP, Lexmark, Afico, Konica Minolta, Oki and Asmsung were among those affected.
