Do You Still Trust the Printer In You Network?

28c3: Hacking MFPs, Part2 - PostScript: Um, you’ve been hacked

Costin found a method to exploit the firmware update capability of certain Xerox MFPs to upload his crafted PostScript code. He was able to run code to dump memory from the printer. This could allow an attacker to grab passwords for the administration interface or access or print PIN-protected documents.


28c3: Print Me If You Dare

Cui discovered that he could load arbitrary software into any printer by embedding it in a malicious document or by connecting to the printer online. As part of his presentation, he performed two demonstrations: in the first, he sent a document to a printer that contained a malicious version of the OS that caused it to copy the documents it printed and post them to an IP address on the Internet; in the second, he took over a remote printer with a malicious document, caused that printer to scan the LAN for vulnerable PCs, compromise a PC, and turn it into a proxy that gave him access through the firewall.
