Is it wise to place all our eggs in what appears to be a very leaky digital basket?
OPINION: As agriculture continues its march into the digital age - where farmers, paddocks, machines and inputs are all interconnected - one must wonder whether an individual or organisation could wreak havoc if they broke into operating systems.
A hacker at a recent conference in Las Vegas demonstrated his ability to get the 1993 video game Doom to play on a John Deere 4240 tractor control console. This latest hack follows a ransom-ware attack on AGCO - the manufacturer of brands such as MF, Fendt and Valtra - in May, that affected production, parts support and invoicing for up to two months.
John Deere, a leader in bringing digital technology to the farm, said the hack on its tractor was restricted to one machine and didn't pose any threat to the company's overall system. However, it is an embarrassing reminder that electronics remain vulnerable to outside interference.
Industry advisors point out that the JD company relies on what is considered outdated software to run the onboard systems. Chief among these is Windows CE, that is licensed to OEM's and will see support withdrawn in 2023.
In a telephone interview, the hacker ('Sick Codes') noted that he set out to investigate the vulnerability of the whole food supply chain infrastructure, because nobody else was doing so. He was not reassured by what he found.
Although there appears to be only one hacker bringing this to our attention, his ability to run an early version of Doom software on a consul that we are told is totally secure, suggests there may be an underlying problem. The fact that he was able to get around the software locks installed by John Deere's engineers should make any existing, or potential users, of such systems a little wary. As the demonstration showed, entry into systems and code changes are possible.
Installing and running software that comes from the early 1990s, as does Linux and Microsoft CE, enables the less tech-savvy to visualise the age of the software upon which many systems rely.
Those same insiders also claim that JD has incorporated open licence software into its operating systems and that by doing so it is contractually bound to make it public. Correct or not, it suggests that JD might be at risk of legal action for not complying with licence agreements - most likely from those fighting for the right to repair their own machines.
Of course, John Deere has been active in promoting digitisation, but at the same time, defending the practice of restricting the repair of tractors to its dealers, refusing external, non-authorised access to farmers or DIY mechanics.
Yet, JD is unlikely to be the only company that has this sort of software at the core of its systems and other manufacturers must be watching developments with alarm.
Given that 'Agriculture 4.0' is being touted as the digital roadway to transform farming into a data-driven and automated provider of food for the burgeoning population over the next decase, is it wise to place all our eggs in what appears to be a very leaky digital basket?
OPINION: With the 2024 edition of National Fieldays behind us, it would be fair to say that although the mood was positive – a plus, given the negative sentiment across the rural sector – you must wonder if this showcase format’s days are numbered.
The Forestry Hub returns to Fieldays for its third consecutive year, showcasing how trees and wood are transforming New Zealand.
OPINION: The annual Fieldays at Mystery Creek next week should inject some much-needed energy into the agricultural sector, however, a mate of the Hound questions whether the organisers truly understand that most of the exhibitors are hoping to see farmers – not just all-and-sundry – coming through the turnstiles.
This year’s Fieldays will feature a Rural Advocacy Hub - bringing together various rural organisations who are advocating for farmers and championing their interests as one team, under one roof, for the first time.
It's that time again to break out the gumboots and a warm coat for the National Fieldays, which for 2023, returns to its normal mid-winter timeslot.
European milk processors are eyeing more cheese and milk powder exports into South America following a landmark trade agreement signed last month.
Two European dairy co-operatives are set to merge and create a €14 billion business.
DairyNZ's Kirsty Verhoek ‘walks the talk’, balancing her interests in animal welfare, agricultural science and innovative dairy farming.
"We at Ministry for Primary Industries (MPI) and you at Dairy News said over six months ago that the dairy industry would bounce back, and it has done so with interest.”
Wairarapa sheep and beef farmer Karen Williams is the new chief executive of Irrigation New Zealand.
Whole milk powder prices on Global Dairy Trade (GDT) remains above long run averages and a $10/kgMS milk price for the season remains on the card, says ASB senior economist Chris Tennent-Brown.
