Popular printer brands are prone to attacks

February 23, 2017 admin Hardware 2017february23_hardware_c, cyber security, cyber threats, hardware, printer, vulnerabilities

2017February23_Hardware_CDo you have security measures in place for your office’s printers? By “security,” we don’t mean locked doors or watchful guards; we’re referring to security against hackers that use printers as a weapon. Despite many companies going paperless, printers are still essential in most offices. And based on recent reports, popular printer brands are targeted for corruption.

Which printers are prone?

Based on the study made by Ruhr University Bochum researchers, printer brands such as Hewlett Packard (HP), Brother, Dell, Samsung, and several others are prone to different types of cyber attacks. Online printers from these brands could serve as cyber criminals’ path in which to steal credentials, corrupt a printer, or leak sensitive data from printed documents obtained through a printer’s memory.

Printers serve the basic purpose of turning computer documents into paper and have never been a typical entry-point of hackers’ attacks. Government and corporate offices, business establishments, non-profit organizations, and homes own one, and when you think about the fact that most printers are linked to computer owners’ internal networks, this expansion of cyber theft to printers begin to make even more sense.

How can attacks be made?

Researchers identified security vulnerabilities that would enable hackers to corrupt common printer languages such as PostScript and PJL, which they could then use to launch Distributed Denial-of-Service attacks or reset the corrupted printer to its factory defaults, also termed as ‘protection bypass.’ Other ways in which hackers could exploit their access are through print job manipulations, which could lead to minor cases of printing corruptions or persistent printing distortions, and information disclosure, the leaking of sensitive information.

What safety measures are being developed?

The researchers who discovered the vulnerabilities developed the PRinter Exploitation Toolkit (PRET), a program designed to determine if a printing device is a likely target. This toolkit ‘connects to a device via network or USB and exploits the features of a given printer language, and is complemented by a wiki page that documents attacks made. It’s worth noting that more printer models and brands haven’t been tested due to the team’s lack of resources. But with this open-source toolkit, vulnerabilities of many brands and models may soon be identified.

Stealing information online is far from being a novelty in cyber security. But to do so through printers requires a special set of skills. It’s too soon to tell whether this form of cyber thievery is going to pose serious threats in the future, but regardless of how further studies progress, failing to implement security protocols for your network can cost you dearly. Get ready for any security threat by contacting our security experts now.

The latest Cloud Print service from Google

January 23, 2017 admin Hardware 2017january23_google_c, access, cloud, computer, devices, google, hardware, internet, printer, printing

img-cloud-printing-170px-op3Not too long ago, the thought of being able to access printers from your computer, tablets or smartphones was almost unheard of. But today, it’s a completely different story — enter Google’s Cloud service. Now you can access both regular and Internet-enabled printers through the web. Read on for more information.

First things first, the printer needs to be connected to your primary computer (the one you’ll use to access the printer in the future). Once connected, the computer can be added to Cloud Print. If it isn’t already installed, you need to install Chrome for Windows or Mac. From there, type chrome://devices into the address bar to bring up devices Chrome can work with. Click “Add printer” and make sure the printer you want to link is ticked.

From the same screen, you’ll be able to configure printer settings. Click Manage next to any of the listed printers to upload new print jobs, rename or remove printers, or share a printer with someone else. This allows you to give certain people access to your printer.

If you need to print something off your mobile device, you can do so with the Cloud Print app on Android, where a print option should appear in the Sharing menu. It’s slightly trickier on iOS, but you can still cloud print from Google’s iOS apps using the Google-recommended file management, transfer and printing application PrintCentral Pro to bridge the gap. And as expected, Cloud Print works seamlessly with Chromebooks as well. Just choose Print from the main menu and voila!

If you’re interested in hearing more news on Google’s Cloud Print function or staying up-to-date on the IT world, feel free to let us know.
