Unstoppable exploit in Nintendo Switch opens door to homebrew and piracy

The Nintendo Switch may soon be a haven for hackers, but not the kind that want your data — the kind that want to run SNES emulators and Linux on their handheld gaming consoles. A flaw in an Nvidia chip used by the Switch, detailed today, lets power users inject code into the system and modify it however they choose.

The exploit, known as Fusée Gelée, was first hinted at by developer Kate Temkin a few months ago. She and others at ReSwitched worked to prove and document the exploit, sending it to Nvidia and Nintendo, among others.

Although responsible disclosure is to be applauded, it won’t make much difference here: this flaw isn’t the kind that can be fixed with a patch. Millions of Switches are vulnerable, permanently, to what amounts to a total jailbreak; only new ones with code tweaked at the factory will be immune.

That’s because the flaw is baked into the read-only memory of the Nvidia Tegra X1 used in the Switch and a few other devices. It’s in the “Boot and Power Management Processor” to be specific, where a misformed packet sent during a routine USB device status check allows the connected device to send up to 64 kibibytes (65,535 bytes) of extra data that will be executed without question. You need to get into recovery mode first, but that’s easy.

As you can imagine, getting arbitrary code to run on a device that deep in its processes is a huge, huge vulnerability. Fortunately it’s only available to someone with direct, physical access to the Switch. But that in itself makes it an extremely powerful tool for anyone who wants to modify their own console.

Modding consoles is done for many reasons, and indeed piracy is among them. But people also want to do things Nintendo won’t let them, like back up their saved games, run custom software like emulators or extend the capabilities of the OS beyond the meager features the company has provided.

Temkin and her colleagues had planned to release the vulnerability publicly on June 15 or when someone releases the vulnerability independent of them — whichever came first. It turned out to be the latter, which apparently came as a surprise to no one in the community. The X1 exploit seems to have been something of an open secret.

The exploit was released anonymously by some hacker and Temkin accordingly published the team’s documentation of it on GitHub. If that’s too technical, there’s also some more plain-language chatter about the flaw in a FAQ posted earlier this month. I’ve asked Temkin for a few more details.

In addition to Temkin, failOverflow announced a small device that will short a pin in the USB connector and put the device into recovery mode, prepping it for exploitation. And Team-Xecuter was advertising a similar hardware attack months ago.

The answer to the most obvious question is no, you can’t just fire this up and start playing Wave Race 64 (or a pirated Zelda) on your Switch 15 minutes from now. The exploit still requires technical ability to implement, though as with many other hacks of this type, someone will likely graft it to a nice GUI that guides ordinary users through the process. (It certainly happened with the NES and SNES Classic Editions.)

Although the exploit can’t be patched away with a software update, Nintendo isn’t powerless. It’s likely that a modified Switch would be barred from the company’s online services (such as they are) and possibly the user’s account, as well. So although the hacking process is, compared with the soldering required for modchips of decades past, low on risk, it isn’t a golden ticket.

That said, Fusée Gelée will almost certainly open the floodgates for developers and hackers who care little for Nintendo’s official ecosystem and would rather see what they can get this great piece of hardware to do on their own.

I’ve asked Nintendo and Nvidia for comment and will update when I hear back.

Amazon eyes a move into home shopping TV with possible Evine buy

Amazon has now passed 100 million subscribers for its Prime loyalty shopping program, underscoring its growth as an e-commerce, cloud services and streaming media behemoth. But it’s also looking beyond the internet, at more traditional ways to reach consumers.

An industry source claims that Amazon is interested in making a buy in TV home shopping. Specifically, we’re told there have been acquisition discussions between Amazon and Evine Live, which operates a pay-TV home shopping channel of the same name. Another source also heard Amazon was one of several companies potentially interested in buying Evine.

The stage of these alleged discussions is not clear, nor is the price that Amazon would potentially pay. Evine is traded on Nasdaq, and its current market cap is $53 million, at the lower end of its one-year range.

The TV channel was previously the subject of a more public acquisition offer: a group headed by Segel Vision offered to buy it for an enterprise value of $175 million last year, but it eventually walked away after Evine rebuffed the offer multiple times. When TechCrunch reached out to Segel, co-founders Jim Morris and Marvin Segel wrote, “we do not know of any other interest in EVINE,” noting the company’s lackluster financial performance. “This is not the stock movement of a company being looked at.”

Spokespeople for Amazon and Evine declined to comment on rumors and speculation. Separately, we have received no response to messages sent to the CEO of Evine, Bob Rosenblatt, and COO/CFO Tim Peterman.

Evine is a distant third in the world of home shopping channels after QVC and the Home Shopping Network. Yet it still has broad potential reach, with its channel available in 87 million homes across the U.S., in addition to a website and apps. Its business is based on selling a range of merchandise, sometimes in partnerships with celebrities. The company last quarter reported revenues of $193 million with net income of $6.4 million. The latter may sound like a modestly small figure, but it was the first time Evine had posted a net income since 2007, with a rocky stock price to match. (Yet Evine insiders have remained bullish, making dozens of share purchases in the past 12 months, with limited selling.)

Evine has grown up amid some big shifts in the two worlds in which it operates, commerce and media. Two notable trends are that many consumers have switched off their TVs and moved away from shopping in physical stores, turning their attention online (and to their mobile screens) to be entertained and to buy things.

Amazon is both a big benefactor and pace-setter of that trend: the company has become a formidable presence in all things e-commerce and has, in more recent years, been stepping up its game in content, leveraging its cloud services infrastructure to stream third-party media in areas like video and music, as well as its own original programming, bringing a core audience to it all via its Prime subscription service.

There was once a time (before the internet grabbed hold) when home shopping TV helped define the idea of “shopping from your sofa.” But the $2.1 billion acquisition last year of HSN by QVC, creating North America’s third largest e-commerce retailer, was seen by some as a way for the combined companies to “battle Amazon.” The founder of Evine and its former CEO Mark Bozek (who was the basis of the Bradley Cooper character in the film Joy) also clearly identified the Amazon challenge/threat not just for home shopping but retail overall. (Bozek left Evine in 2016 and is now working on a new startup called Live Rocket.)

Yet Amazon’s might is not the full story. Today, e-commerce still accounts for only around nine percent of all retail sales in the U.S., according to figures from the Census Bureau. It’s on the rise, but that proportion speaks to a strong opportunity for online companies that want to capture customers who are not already regular Amazon shoppers and might be more likely to watch broadcast rather than on-demand TV. (Amazon’s Whole Foods buy, you could argue, also helped it target a more traditional channel, with a big move into physical stores.)

Evine is not the leading player in its space, but it has some key pieces in place — such as deals to broadcast into a multitude of local pay-TV markets, and an audience of TV viewers who are already watching and buying from Evine and channels like it — for a larger player to come in and use that infrastructure to build inroads to audiences that might not otherwise be reaching. It could also give those who sell on Evine a potentially much bigger audience to access through its digital channels.

QVC-style programming is an area that Amazon has tried to break into previously using its existing digital platforms. Back in 2016, Amazon launched “Style Code Live,” where users could watch a show with fashion and beauty tips and instantly buy the products. That effort was shelved in 2017 with no explanation for the cancellation, but it shows that the company does have an interest in the area.

Coincidentally, several months ago, reports surfaced that Amazon was looking at acquisitions of smaller, niche-interest television stations to complement its advances in streamed video surfaces.

Another interesting side note: Earlier this year Amazon took a $600 million investment into a company called StarTek, a call center operator and engagement outsourcing specialist that provides services in the cable TV, telecom and retail industries. The investment was little reported at the time, and when we asked about it, StarTek would only say that the deal was related to “commercial services” provided to Amazon.

Evine has been through several iterations: It was founded back in 1990 as Value Vision, went public in 1991 and at one time counted NBC as an investor, which had a significant enough stake to rebrand the company as ShopNBC. NBC eventually sold its stake and the company rebranded as ShopHQ, and then Evine in 2015 as part of Bozek’s attempted turnaround of the company.
