Printer Botnet Has “Attacked” Over 100,000 Printers

A very talented individual with the nickname “Stackoverflowin” has managed to hack over 100 thousand printers that are connected to the cloud. The hacker has been reported by malware researchers who spoke with him to not do this for his own goals, but rather to display the possibilities of cyber-security attacks and underline this issue as more important.

How The Attack Was Conducted

What the hacker has done for this attack is to examine the devices’ port configuration and use this information to create a script. This automated script analyzes the ports on each printer and looks for unsecured ones. As soon as those are discovered, the script is activated and it has configurations to print a rather funny message:

The hacker managed to penetrate the defenses of well-known printer manufacturers such as:

Brother
Canon
Epson
HP
Lexmark
Konica
Minolta
Oki
Samsung

The message also falsely claims for a botnet to be exhibiting attacks on the devices, but in reality, it is the script which has been sent manually by the hacker to multiple locations with open ports.

But the script is not just a simple print script. For it to work, “Stackoverflowing” claims that he or she used exploit that utilizes remote code execution vulnerabilities.
