Surprise! People Still Use Fax Machines

Posted August 18, 2018 12:00 AM by M-ReeD
Pathfinder Tags: Fax Machine hacking

Remember the decades’ old monstrosity called the fax machine, taking up valuable real estate in either the home or office?

My father was so enchanted by the fax machine back in the mid to late 90s that as soon as it became relatively affordable, he ran out and bought the device; a pointless but awe-inspiring piece of equipment that sat in our “home office” waiting for faxes that would never come.

As it turned out, we had little use for our fax machine, yet all of these years later it seems that there are industries that still rely on the machines to communicate vital information, which is what inspired one security firm to investigate whether such devices are vulnerable to hacking.

Spoiler alert: They are.

Think outdated technology and electronic equipment is safe from hackers? Think again, according to recent findings from the cyber security firm Check Point.

According to reports, the Israel-based team discovered that tens of millions of old office fax machines can be used as a backdoor, allowing hackers a point of entry into an organization’s network.

The security flaw, according to the report, allows hackers to send an image file (or a file that mimics an image file) containing malicious software via phone line. Once the image is received, it is decoded and uploaded into the memory of the fax machine, thereby granting the hackers control over the device and encouraging the spread of the malicious code throughout the network.

"Many companies may not even be aware they have a fax machine connected to their network, but fax capability is built into many multifunction office and home printers," said Yaniv Balmas, group manager of security research at Check Point.

Considering that a number of industries still use fax machines, including industries that deal in sensitive data such as banking, healthcare and law, experts suggest that companies should determine whether these devices can be updated. Additionally, experts recommend placing fax machines on a secure network separate from networks carrying sensitive data.

Do you still use a fax machine?

I don't use a fax, but I've heard the complaints of those who do. Worse than telemarketing callers are people that send you ads and you pay for the ink and paper!

Our last two printer/scanners had one, but they were never used to fax anything.

I like fax some professions require some communication by fax such as Medical in Ontario CA. My problem they do not function at all well on VOIP. With our email laws a letter $ 1.00 is legal and fax is legal for pennies if that.

I just bought a house. I bought direct from the seller and we used the same lawyer for closing. Seems my lender and the lawyer still depend on fax machines. I told them that for me everything would have to handled online and/or through email or the deal was off.

They adjusted. And only did cursory whining. They both have IP comms but are desperately holding onto the past.

And thank the Lord there weren't any real estate agents involved to compound the problem.

Still a lot of legal stuff out there that rely on actual or facsimile copies of signatures - usually a rider that facsimile copies are accepted.

I still use the fax machine for certain suppliers for PO's. No paper saving for many as they end up printing off an email anyway, and if there have been questions or concerns, the printed copy my even run into more than one page.

There are quite a number of online services and apps that are nationally and internationally recognized as providing for valid e-signatures.

I've been fighting this presumed quandary (meaning resistance to change) since the early days of determining how to get valid and authoritative signatures on engineering drawings that originate digitally on CAD systems.

It would be nice to have a direct reference to the original report, but my feeling is that this is unlikely with an actual fax machine, as opposed to a computer with a fax program. A proper fax machine is connected only to a telephone line and its output is purely on paper.

As the article states, most home multi-function printers have a FAX capability and are connected to the home network. I suspect many small businesses use the same. Apparently, an "image" can be crafted to carry some malware which then can infect any vulnerable equipment on the network. One answer is to not enable auto-answer except when you are expecting a fax and then disable it immediately after receipt.

At my last job, in an engineering group, we had a multi-function copier/scanner/printer. It had a fax capability with an IP addy AND a hard wire phone line. It was recognized as being attached to the corporate network so it was our SOP, since we did a lot of DOD work, to have the fax functions turned off by default, and only turned on for pre-arranged comm's by engineering management authority.

Last weekend, 8/10-13, I had to purchase meds online for my dog. My Online vet pharmacy needed a faxed approval from my vet. DEA requirement. Why the DEA has anything to do with veterinary antihistamines I have no clue and I suppose the fax requirement, no to your question text or email are not allowed, has something to do with governmental incompetency / technology latency, but that's the way it is.

In the UK many legal transactions (buying a house) need documents to be faxed. I was told this was because a fax machine can be physically and positively located.

Transfers of players in football (soccer for some of you out there) are also confirmed by fax particularly the international registration. In 2015 David de Gea was supposed to move from Manchester Utd to Real Madrid (currently 3rd & 5th on Forbes list of richest sports teams). This move didnt go through because the fax machine at Santiago Bernabeu didn't accept the paperwork from Utd and then send on the details to UEFA HQ in Switzerland. This probably would have been a record transfer for a goalkeeper (based on fee paid).

My use for the fax machine is inspired by the use of my landline by telemarketers. My fax is set to answer after 6 rings. The telemarketer gets a fax squeal and is discouraged from calling again! To bad our government won't manage telemarketers to keep them off our landlines.

Better yet, see if your carrier has nomorobo (sp?). It uses a list of robotic (telemarketer) numbers and rejects them. You get one ring and the call is gone.
