Apple, Google, Microsoft, WhatsApp sign open letter condemning GCHQ proposal to listen in on encrypted chats

An international coalition of civic society organizations, security and policy experts and tech companies — including Apple, Google, Microsoft and WhatsApp — has penned a critical slap-down to a surveillance proposal made last year by the UK’s intelligence agency, warning it would undermine trust and security and threaten fundamental rights.

“The GCHQ’s ghost protocol creates serious threats to digital security: if implemented, it will undermine the authentication process that enables users to verify that they are communicating with the right people, introduce potential unintentional vulnerabilities, and increase risks that communications systems could be abused or misused,” they wrire.

“These cybersecurity risks mean that users cannot trust that their communications are secure, as users would no longer be able to trust that they know who is on the other end of their communications, thereby posing threats to fundamental human rights, including privacy and free expression. Further, systems would be subject to new potential vulnerabilities and risks of abuse.”

GCHQ’s idea for a so-called ‘ghost protocol’ would be for state intelligence or law enforcement agencies to be invisibly CC’d by service providers into encrypted communications — on what’s billed as targeted, government authorized basis.

The agency set out the idea in an article published last fall on the Lawfare blog, written by the National Cyber Security Centre’s (NCSC) Ian Levy and GCHQ’s Crispin Robinson (NB: the NCSC is a public facing branch of GCHQ) — which they said was intended to open a discussion about the ‘going dark’ problem which robust encryption poses for security agencies.

The pair argued that such an “exceptional access mechanism” could be baked into encrypted platforms to enable end to end encryption to be bypassed by state agencies would could instruct the platform provider to add them as a silent listener to eavesdrop on a conversation — but without the encryption protocol itself being compromised.

“It’s relatively easy for a service provider to silently add a law enforcement participant to a group chat or call. The service provider usually controls the identity system and so really decides who’s who and which devices are involved — they’re usually involved in introducing the parties to a chat or call,” Levy and Robinson argued. “You end up with everything still being end-to-end encrypted, but there’s an extra ‘end’ on this particular communication. This sort of solution seems to be no more intrusive than the virtual crocodile clips that our democratically elected representatives and judiciary authorise today in traditional voice intercept solutions and certainly doesn’t give any government power they shouldn’t have.”

“We’re not talking about weakening encryption or defeating the end-to-end nature of the service. In a solution like this, we’re normally talking about suppressing a notification on a target’s device, and only on the device of the target and possibly those they communicate with. That’s a very different proposition to discuss and you don’t even have to touch the encryption.”

“[M]ass-scale, commodity, end-to-end encrypted services… today pose one of the toughest challenges for targeted lawful access to data and an apparent dichotomy around security,” they added.

However while encryption might technically remain intact in the scenario they sketch, their argument glosses over both the fact and risks of bypassing encryption via fiddling with authentication systems in order to enable deceptive third party snooping.

As the coalition’s letter points out, doing that would both undermine user trust and inject extra complexity — with the risk of fresh vulnerabilities that could be exploited by hackers.

Compromising authentication would also result in platforms themselves gaining a mechanism that they could use to snoop on users’ comms — thereby circumventing the wider privacy benefits provided by end to end encryption in the first place, perhaps especially when deployed on commercial messaging platforms.

So, in other words, just because what’s being asked for is not literally a backdoor in encryption that doesn’t mean it isn’t similarly risky for security and privacy and just as horrible for user trust and rights.

“Currently the overwhelming majority of users rely on their confidence in reputable providers to perform authentication functions and verify that the participants in a conversation are the people that they think they are, and only those people. The GCHQ’s ghost protocol completely undermines this trust relationship and the authentication process,” the coalition writes, also pointing out that authentication remains an active research area — and that work would likely dry up if the systems in question were suddenly made fundamentally untrustworthy on order of the state.

They further assert there’s no way for the security risk to be targeted to the individuals that state agencies want to specifically snoop on. Ergo, the added security risk is universal.

“The ghost protocol would introduce a security threat to all users of a targeted encrypted messaging application since the proposed changes could not be exposed only to a single target,” they warn. “In order for providers to be able to suppress notifications when a ghost user is added, messaging applications would need to rewrite the software that every user relies on. This means that any mistake made in the development of this new function could create an unintentional vulnerability that affects every single user of that application.”

There are more than 50 signatories to the letter in all, and others civic society and privacy rights groups Human Rights Watch, Reporters Without Borders, Liberty, Privacy International and the EFF, as well as veteran security professionals such as Bruce Schneier, Philip Zimmermann and Jon Callas, and policy experts such as former FTC CTO and Whitehouse security advisor, Ashkan Soltani .

While the letter welcomes other elements of the article penned by Levy and Robinson — which also set out a series of principles for defining a “minimum standard” governments should meet to have their requests accepted by companies in other countries (with the pair writing, for example, that “privacy and security protections are critical to public confidence” and “transparency is essential”) — it ends by urging GCHQ to abandon the ghost protocol idea altogether, and “avoid any alternative approaches that would similarly threaten digital security and human rights”.

Reached for a response to the coalition’s concerns, the NCSC sent us the following statement, attributed to Levy:

We welcome this response to our request for thoughts on exceptional access to data — for example to stop terrorists. The hypothetical proposal was always intended as a starting point for discussion.

It is pleasing to see support for the six principles and we welcome feedback on their practical application. We will continue to engage with interested parties and look forward to having an open discussion to reach the best solutions possible.

Back in 2016 the UK passed updated surveillance legislation that affords state agencies expansive powers to snoop on and hack into digital comms. And with such an intrusive regime in place it may seem odd that GCHQ is pushing for even greater powers to snoop on people’s digital chatter.

Even robust end-to-end encryption can include exploitable vulnerabilities. One bug was disclosed affecting WhatsApp just a couple of weeks ago, for example (since fixed via an update).

However in the Lawfare article the GCHQ staffers argue that “lawful hacking” of target devices is not a panacea to governments’ “lawful access requirements” because it would require governments have vulnerabilities on the shelf to use to hack devices — which “is completely at odds with the demands for governments to disclose all vulnerabilities they find to protect the population”.

“That seems daft,” they conclude.

Yet it also seems daft — and predictably so — to suggest a ‘sidedoor’ in authentication systems as an alternative to a backdoor in encrypted messaging apps.

Ekasbo’s Matebot may be the cutest cat robot yet created

If Shrek saw Matebot, no amount of sad-eyes could win him back to Puss in Boots’ side. Created by Shenzhen-based robotics company Ekasbo, Matebot looks like a black and white cartoon cat and responds to your touch by wiggling its ears, changing the expression in its big LED eyes and tilting its head.

Ekasbo's Matebot in a sad mood

Built with voice recognition, infrared technology and seven moving parts, the Matebot is designed to serve as an interactive companion, including for people who can’t keep pets, creator Zhang Meng told TechCrunch at Computex in Taiwan.

The Matebot is controlled with a smartphone app and can be integrated with Android voice control systems. Its price starts at about 4,999 yen or about $45 USD.

Ulo is an adorable security camera that interacts with you while keeping watch over your home

Tired of home security cameras that add nothing to your home (besides, well, surveillance)? The Ulo, created by Luxembourg-based Mu Design, adds a touch of whimsy. The owl-shaped surveillance camera has two big interactive LCD eyes that follow your movements, and its two lenses—a HD camera and motion sensor camera—discreetly hidden in its beak, made of one-way mirrored glass, that capture high-resolution images. .

Mu Design founder Vivien Muller, who is currently showing off Ulo at Computex in Taipei, said he wanted to create a security camera that feels like a pet and makes its owners happy. The Ulo, with its huge, expressive eyes, is certainly adorable. Ulo runs on a Qualcomm Snapdragon 212 series processor and is made with an internal microphone, WifFi and Bluetooth models and an orientation sensor. It can use rechargeable NiMH batteries or be charged with a standard micro USB charger. Ulo also boosts 8GB eMMC and a microSD card clot.

Ulo is controlled by iOS or Android apps. Like other cameras, it can send images to your email when movement is detected, send data to secure devices if requested and stores a few minutes of video locally.

The camera is currently out of stock, but available for pre-order and costs 199 euros, or about $220.

Kurly, a grocery e-commerce startup in Korea, closes upsized $113M Series D round

Kurly, a startup that operates a grocery delivery service in Korea, said today that it has closed an upsized Series D round that reached a total of $113 million.

The company announced the round in April when it was $88 million led by investors that include Sequoia China, however it has now increased by $25 million. That’s thanks to an injection from China’s Hillhouse Capital, a firm which counts Tencent, Meituan and JD.com among its most successful investments.

Launched in 2015 by former Goldman Sachs and Temasek analyst Sophie Kim, its Kurly Market service is designed to provide groceries and produce to customers who don’t have the time or interest to visit regular retail stores for their shopping.

Kurly Market delivers orders by 7am each morning with customers given until 11pm the previous day to place their order.

Korea is the place for speedy deliveries, if that’s your thing. Coupang, a company backed by SoftBank’s Vision Fund that’s widely seen as ‘the Amazon of Korea’ — and valued at $9 billion, to boot — has built out an impressive network that allows same- and next-day delivery for its “millions”of customers.

Coupang CEO Bo Kim told TechCrunch last year that his company was “approaching” $5 billion in revenue for 2018 with 70 percent annual growth. Additionally, he said, one in every two adults in Korea have the Coupang app on their phone and, having started out in Amazon-like areas, Coupang is doubling down on fresh produce with its own cold chain logistics network.

That represents a direct challenge to Kurly, which differentiates itself by operating through its own brands, unlike Coupang, which runs using a marketplace model to connect retailers with consumers. Kurly is also focused on convenience over cost savings, indeed its service began in Seoul’s high-end Gangnam neighborhood but has since expanded more widely.

Kurly Market products are focused on quality and convenience over price

Still, investors are bullish on Kurly and its laser focus on produce and groceries.

Kurly said its revenue grew three-fold year-on-year to reach $131 million in 2018, although it did not provide profit/loss figures.

“The latest round of investment is a major endorsement of the progress we’ve made differentiating ourselves in the market through our cold-chain fulfillment infrastructure and unique offering of premium, curated products. Our focus is on further strengthening our relationships with our suppliers, developing our fulfillment infrastructure and continually improving our customer experience,” Kim said in a statement.
