Why Firmware Is So Vulnerable to Hacking, and What Can Be Done About It

When Kaspersky Lab revealed last week that it had uncovered a sophisticated piece of malware designed to plant malicious code inside the firmware of computers, it should have surprised no one. And that’s not just because documents leaked by Edward Snowden have shown that spy agencies like the NSA have an intense interest in hacking the firmware of systems, but also because other researchers have shown in the past how insecure firmware—in nearly all systems—is. Computers contain a lot of firmware, all of which is potentially vulnerable to hacking—everything from USB keyboards and web cams to graphics and sound cards. Even computer batteries have firmware. “There’s firmware everywhere in your computer, and all of it is risky,” says security researcher Karsten Nohl, who demonstrated last year how he could embed malicious code in the firmware of USB sticks. There’s also firmware in all of our popular digital gadgets—smartphones and smart TVs, digital cameras, and music players. Most of it is vulnerable for the same reasons the firmware the Equation Group targeted is vulnerable: it was never designed to be secure. Most hardware makers don’t cryptographically sign the firmware embedded in their systems nor include authentication features in their devices that […]

HP Releases Firmware Update To Prevent Printer Hacking

Image via Wikipedia

A few weeks ago, a group of researchers announced that they were able to exploit a security hole in some older Hewlett-Packard printers that allowed them to take the printers over. In one demonstration, they were able to heat up paper to the point where it started smoking, and in another were able to send social security numbers from documents to other systems.

The problem was that the printers did not check to verify to source of any firmware updates – the software that controls the actual physical hardware in the computer. So the researchers were able to update the printers with fake firmware that contained software that let them control the printers and take advantage of their network access and other systems.

After this report was announced, HP released a statement stating that no systems had been reported compromised by this potential attack. Moreover, the company claimed that this would not impact any printers produced after 2009. Printers produced after that point did check for a digital signature.

Well, now people with older printers can rest easy, as well. HP has released a firmware update that should fix the security exploit, and is actively working with its customers to make sure that the updates get installed.

What’s not clear is whether the firmware update could fix a printer whose security has already been compromised, but to date I haven’t seen any reports that this exploit has been employed against anybody, so that’s probably a non-issue.

Despite the quick fix, one thing that this does highlight is the increasing vulnerability of embedded systems. Especially as more and more of the things we use every day use networks, even things we wouldn’t think of in a computing sense.

HP Plugs Security Hole With LaserJet Firmware Update, Says No Record Of Printers Set Ablaze By Hackers

Remember when researchers claimed a massive security vulnerability could potentially enable hackers to remotely take over Hewlett-Packard LaserJet printers and even cause them to burst into flames? Fun times, for sure.

Of course, HP was quick to point out that the researchers had it all wrong, lamented the “sensational and inaccurate reporting” surrounding the supposed security flaw and said not a single customer had reported any instances of unauthorized access to its LaserJet printers.

Nevertheless, the company recognized that there was indeed a potential security vulnerability with printers placed on a public network without a firewall, and at the time said it would soon issue a fix.

This morning, HP announced that the firmware update is now available and said it has still not received any customer reports of unauthorized access. From the looks of it, not a single hacker exploited the security flaw to burn down a house, skyscraper, hotel, casino, school or shed.

The company reiterated its recommendation to secure devices by placing printers behind a firewall and to disable remote firmware upload on exposed printers whenever possible.
