Recently, it had become known that on network-capable HP printers a significant problem in the security have been found. The Fund succeeded the researchers from the University of Columbia. Affected is the remote check the access permission, where the focus is at the printers, which can be accessed via the Internet.
PrinterHall assumes that millions of printers with this printer hack could be affected. They claimed that the virus even on the printer can be transmitted which are connected via USB to an Internet-enabled computer. One problem is that even a high-quality anti-virus program on the computer cannot find the pest programs in the printer software.
Even fire hazard in HP laser printers?
While the risks for the user of the infected printer not only, that stolen sensitive data by third parties can be. Supposedly the to hack also cause, that specifically in the printer control panel, can cause errors, for example, by a permanent heating of laser printers, which in turn in turn pulls an increased risk for the development of fires in. HP strongly rejects these accusations and claims that the laser printer with an overheating protection are equipped, which let not go to also by interfering with the firmware, since they are based on the principle of Thermomechanics.
A network firewall to let completely go to
Even more, according to Columbia of University researchers, he can hack for HP printers. He let himself use, to be able to spy on all networks. In the firewall of the network should can completely bypass. Here, too, there are cons of HP. Hewlett Packard announced that this would be possible only with certain settings of the printer at all. And they would find themselves focusing on Mac and Linux systems. But just Linux is like the best used as the central server in a network operating system.
HP Announces patches and updates
Meanwhile sought HP, to solve the problem. For some Printers will be offered a special updatethat disables the remote functions can. For more devices special patches have been announced. HP also stressed that a hack attack from the outside on a printer in a network protected by a firewall would not be possible. There would have to be an infected PC within the network architecture. It is irrelevant whether the firewall on the connected computers or in the DSL router will be. The best protection would still not unchecked executable download from the Internet or from a mail out on the computer.
Danger averted by updates?
In the laboratory the infection of HPprinter with a standard print file could be adjusted. In practice this may be but impossible according to the experts, because alone the operating principles of the Windows print control can effectively prevent such an attack. For this but should keep its printer driver always up to date, with the support of the manufacturers is the only advisable address.
On the question of whether the firmware updates and patches that could definitively close vulnerability HP kept covered and formulate the General dangers arising from the use of networks of all kinds to hacker attacks.
First consequences of vulnerability
The first consequences of this vulnerability in its printers got HP already to feel. The head of the research group of the University of Columbia, David Goldblatt, already a class action lawsuit in a California Court handed a on December 1, 2011. He founded it so that Hewlett Packard the vulnerability must have been known for some time, because the first hints have already surfaced in an article from the year 2010.
The lack of activity on the part of HP could not bring with the California laws for the protection of consumers under a hat. What are the economic consequences in the form of court and lawyer fees and compensation for affected users that will entail, can currently still not specifically be estimated. Insiders expect that the process may even over years could go.
