IBM Africa and Hello Tractor pilot AI/blockchain agtech platform

IBM Research and agtech startup Hello Tractor have developed an AI and blockchain-driven platform for Africa’s farmers. The two companies will pilot the product in 2019 through an ongoing partnership co-financed by IBM.

Dubbed Digital Wallet in beta, the cloud-based service aims to support Hello Tractor’s business of connecting small-scale farmers to equipment and data analytics for better crop production.

“Agriculture is a complex industry that can have so many different variables. We’re bringing a decision tool to the Hello Tractor ecosystem powered by AI and blockchain,” Hello Tractor CEO Jehiel Oliver told TechCrunch.

The startup joined IBM Research to demo the new service at Startup Battlefield Africa in Lagos.

Available to Hello Tractor clients, the online platform will use a digital ledger and machine learning to capture, track, and share data, while “creating end-to-end trust and transparency across the agribusiness value chain,” according to an IBM release.

Digital Wallet will draw on remote and IoT-based weather-sensing methods and AI to help farmers determine crops and inputs, choose when to plant and optimize and predict crop yields.

The cloud-based dashboard also employs a blockchain ledger to improve multiple points of Hello Tractor’s business.

“We’re an agricultural technology company. Our platform connects farmers who need tractor services to tractor owners who own these assets as a business. We create that marketplace to bring supply and demand together,” said Oliver.

The demand stems from the 80 percent of Sub-Saharan Africa’s crops harvested without tractors or machinery and the 50 percent of the continent’s farmers who suffer post-harvest losses annually, according to IBM and the Food and Agricultural Organization.

IBM and Hello Tractor’s Digital Wallet will also loop in data from fleet owners regarding tractor use, track and predict repairs and servicing and build credit profiles to open bank financing for farmers.

Hello Tractor is a connecting service — neither the startup nor its farming clients own tractors. Founded in 2014, the venture began operations in Nigeria and has expanded into Kenya, Mozambique, Senegal, Tanzania and Bangladesh within the last year, according to its CEO. A for-profit entity, Hello Tractor has raised funding from private investors, DFI grants and a seed round.

The company currently generates revenue by selling the tractor-monitoring devices and software subscriptions for its app, according to Oliver. Hello Tractor doesn’t yet charge transactional fees for connecting tractors to farmers, “but we’ll be testing that next year,” he said.

The startup also plans to create broader revenue opportunities from data analytics.

“At this phase we focus primarily on mechanization, but coupling the insights being generated through that device with the IBM platform solutions specifically for agriculture can extend the value we offer our customers and…be monetized,” said Oliver.

He estimates the business of connecting small-scale farmers to tractors as a “multi-billion market” globally and pointed to Nigeria as the African nation with “the largest inventory of arable-uncultivated farmland,” 37 percent of the country, according to World Bank data.

IBM Research’s co-financing to build Digital Wallet does not include any equity stake in Hello Tractor, IBM confirmed.

The collaboration aligns with IBM’s global agricultural strategy, embedded largely in its Watson AI business platform and global agtech partnerships. As TechCrunch covered, IBM partnered with Kenyan agtech startup Twiga earlier this year to introduce to Twiga’s network of vendors a blockchain-enabled working capital platform.

IBM Research views the partnership “as scientific research collaboration,” according to VP Solomon Assefa.

“Through all its touch points — farmers, machinery, dealers, crop yields, data inputs — Hello Tractor is convening the whole agricultural ecosystem,” he said.

As discussed at Startup Battlefield Africa, Africa is shaping its own blockchain-focused startups and use cases — characterized more by utility than speculation. On the crypto-side, there were several 2018 ICOs, including remittance startup SurRemit’s $7 million token launch, payments venture Wala’s $1 million offering and one by South African solar energy startup Sun Exchange.

IBM Research and Hello Tractor teams will continue to build out the blockchain-enabled Digital Wallet on a lab, engineer and business level throughout 2019.

“We’re cultivating the partnership… including the executive and go-to-market side. You also have to focus on how you scale,” said Assefa.

At Blind, a security lapse revealed private complaints from Silicon Valley employees

Thousands of people trusted Blind, an app-based “anonymous social network,” as a safe way to reveal malfeasance, wrongdoing and improper conduct at their companies.

But Blind left one of its database servers exposed without a password, making it possible for anyone who knew where to look to access each user’s account information and identify would-be whistleblowers.

The South Korea-founded company made its way into the U.S. in 2015, when it quickly became a highly popular anonymous social network for major tech companies, touting employees from Apple, Facebook, Google, Microsoft, Twitter, Uber, and more. Blind last month secured another $10 million in new funding after a $6 million raise in 2017. But it was only when the social network became the root of several high profile scandals when Blind gained mainstream attention, including revealing allegations of sexual harassment at Uber — which later blocked the app on its corporate network.

The exposed server was found by a security researcher, who goes by the name Mossab H, who informed the company of the security lapse. The security researcher found one of the company’s Kibana dashboard for its backend ElasticSearch database, which contained several tables, including private messaging data and web-based content, for both of its U.S. and Korean sites. Blind said that the exposure only affects users who signed up or logged in between November 1 and December 19, and that the exposure relates to “a single server, one among many servers on our platform,” according to Blind executive Kyum Kim in an email.

Blind only pulled the database after TechCrunch followed up by email a week later. The company began emailing its users on Thursday after we asked for comment.

“While developing an internal tool to improve our service for our users, we became aware of an error that exposed user data,” the email to affected users said.

Kim said that there is “no evidence” that the database was misappropriated or misused, but did not say how it came to that conclusion. When asked, the company would not say if it will notify U.S. state regulators of the breach.

Blind’s chief executive Sunguk Moon, who was copied on many of the emails with TechCrunch, did not comment or acknowledge the exposure.

At its core, the app and anonymous social network allows users to sign up using their corporate email address, which is said to be linked only to Blind’s member ID. Email addresses are “only used for verification” to allow users to talk to other anonymous people in their company, and the company claims that email addresses aren’t stored on its servers.

But after reviewing a portion of the exposed data, some of the company’s claims do not stand up.

We found that the database provided a real-time stream of user logins, user posts, comments and other interactions, allowing anyone to read private comments and posts. The database also revealed the unencrypted private messages between members but not their associated email addresses. (Given the highly sensitivity of the data and the privacy of the affected users, we’re not posting data, screenshots or specifics of user content.)

Blind claims on its website that its email verification “is safe, as our patented infrastructure is set up so that all user account and activity information is completely disconnected from the email verification process.” It adds: “This effectively means there is no way to trace back your activity on Blind to an email address, because even we can’t do it.” Blind claims that the database “does not show any mapping of email addresses to nicknames,” but we found streams of email addresses associated with members who had not yet posted. In our brief review, we didn’t find any content, such as comments or messages, linked to email addresses, just a unique member ID, which could identify a user who posts in the future.

Many records did, however, contain plaintext email addresses. When other records didn’t store an email address, the record contained the user’s email as an unrecognized encrypted hash — which may be decipherable to Blind employees, but not to anyone else.

The database also contained passwords, which were stored as an MD5 hash, a long-outdated algorithm that is nowadays easy to crack. Many of the passwords were quickly unscrambled using readily available tools when we tried. Kim denied this. “We don’t use MD5 for our passwords to store them,” he said. “The MD5 keys were a log and it does not represent how we are managing data. We use more advanced methods like salted hash and SHA2 on securing users’ data in our database.” (Logging in with an email address and unscrambled password would be unlawful, therefore we cannot verify this claim.) That may pose a risk to employees who use the same password on the app as they login to their corporate accounts.

Despite the company’s apparent efforts to disassociate email addresses from its platform, login records in the database also stored user account access tokens — the same kind of tokens that recently put Microsoft and Facebook accounts at risk. If a malicious actor took and used a token, they could login as that user — effectively removing any anonymity they might have had from the database in the first place.

As well intentioned as the app may be, the database exposure puts users — who trusted the app to keep their information safe and their identities anonymous — at risk.

These aren’t just users, but also employees of some of the largest companies in Silicon Valley, who posts about sexual harassment in the workplace and discussing job offers and workplace culture. Many of those who signed up in the past month include senior executives at major tech companies but don’t realize that their email address — which identifies them — could be sitting plaintext in an exposed database. Some users sent anonymous, private messages in some cases made serious allegations against their colleagues or their managers, while others expressed concern that their employers were monitoring their emails for Blind sign-up emails.

Yet, it likely escaped many that the app they were using — often for relief, for empathy, or as a way to disclose wrongdoing — was almost entirely unencrypted and could be accessed, not only by the app’s employees but also for a time anyone on the internet.

Defense Secretary James Mattis steps down

The man who led the Department of Defense for the first two years of the Trump administration will wrap up his tenure early next year. Retired Marine General James Mattis will leave his post by February 28, 2019. Mattis, who retired from the Marine Corps in 2013, received a special congressional waiver to serve as defense secretary.

President Trump characteristically announced the retirement in a pair of tweets, followed by a full resignation letter from Mattis.

In the letter, Mattis alludes to his fundamental ideological differences with Trump in leading the U.S. and interacting with its allies:

“My views of treating allies with respect and also being clear-eyed about both malign actors and strategic competitors are strongly held and informed by over four decades of immersion in these issues,” Mattis writes.

“Because you have the right to have a secretary of defense whose views are better aligned with yours… I believe it is right for me to step down from my position.”
