How lawyers help bring your acquisition deal to fruition

Last week when Salesforce announced it was buying ClickSoftware for $1.35 billion you might not have realized it, but the law firm Shearman & Sterling was advising Salesforce throughout the deal. In fact, there are lawyers involved in every transaction of this sort, from the initial call to the closing.

As you would expect, there are hundreds of tiny details involved in bringing a deal to fruition, from checking the validity of the offer to checking the financial health of the target company, negotiating a price and terms and clearing it with the boards/stockholders. Even after the deal is signed and agreed upon by both companies, the lawyers often have to ease it through the regulatory process before it finally closes.

The attorneys act as project managers, working with company executives and boards of directors, guiding them through the lengthy transaction process, advising them on the legal side of the equation — all while working with the investment banks to make sure everything goes as smoothly as possible.

Looking for a target

A company like Salesforce doesn’t go out and buy ClickSoftware randomly. There is in fact a method to its M&A madness. As I wrote in an article describing the process in 2016:

Blade raises $4.3M from Coinbase, SV Angel to reshape cryptocurrency derivatives trading

Exchanges like Coinbase have ballooned in size by taking the mechanics of equity markets and fitting them to cryptocurrency markets, but as the space expands in its scope and craftiness, new exchanges trading asset classes native to cryptocurrency are taking off and attracting the attention of top Silicon Valley VCs. Oh, and Coinbase, too.

Blade is a new cryptocurrency derivatives exchange launching in three weeks. Prior to starting the company, CEO Jeff Byun and his co-founder Henry Lee founded OrderAhead, a delivery startup platform that was eventually acquired in-part by Square in 2017. The pair’s newest company shares little in common with their previous venture, but they are bringing aboard some of the same investors to support them.

Blade is announcing that they’ve raised $4.3 million in seed funding from a host of investors, including Coinbase, SV Angel, A.Capital, Slow Ventures, Justin Kan and Adam D’Angelo.

The exchange is tackling perpetual swap contracts.

Perpetuals are a crypto-native trading instrument that Byun says are “arguably the fastest growing segment of cryptocurrency trading.” They allow traders to bet on the future values of cryptocurrencies in relation to another and the instruments have no expiration dates, unlike fixed maturity futures. Traders can bet on how the price of Bitcoin can increase relative to USD, but they can also make bets relative to other altcoins like Monero, DogeCoin, Zcash, Ripple and Binance Coin. Here’s what’s on the Blade menu at the moment.

Blade’s noteworthy spins on perpetuals trading — compared to other exchanges — are that most of the contracts will be set up on simplified vanilla contracts, the perpetuals will also be margined/settled in USD Tether and the company is offering higher leverages (up to 150x on BTC-USD and BTC-KRW) on trades.

Blade is raising funds from Silicon Valley’s VCs, but U.S. investors won’t be legally able to participate in the exchange. U.S. government agencies have been a bit more stringent in regulating cryptocurrencies, so there’s more trading activity taking place on exchanges outside the jurisdiction. Blade itself is an offshore entity with a U.S. subsidiary; its primary market is East Asia.

“It’s kind of a bifurcated market,” Byun tells TechCrunch. “Either you have exchanges like Coinbase or Gemini or Bitrex that cater to the U.S. market that are highly regulated or the exchanges that cater to the non-U.S. market that are much less regulated, but that’s where most of the volume is.”

While the company is still three weeks away from launch, the founders have bold ambitions.

“In the long term, we want to be the CME (Chicago Mercantile Exchange) of crypto,” Byun tells me. “Coinbase and Binance are building this foundational structure for crypto, but I think we are too and in a sense that derivatives are at their core about risk transfer, we want to be building the foundational layer for risk transfer in the crypto markets.”

Verizon is selling Tumblr to WordPress parent, Automattic

Six years after Yahoo purchased Tumblr for north of $1 billion, its parent corporation is selling the once-dominant blogging platform. WordPress owner Automattic Inc. has agreed to take the service off of Verizon’s hands. Terms of the deal are undisclosed, but the number is “nominal,� compared to its original asking price, per an article in The Wall Street Journal.

Axios is reporting that the asking price for the platform is “well below $20 million,” a fraction of a fraction of its 2013 price tag.

Once the hottest game in town, the intervening half-decade has been tough on Tumblr, as sites like Facebook, Instagram, Reddit and the like have since left the platform in the dust. More recently, a decision to ban porn from the platform has had a marked negative impact on the service’s traffic. According to Sensor Tower, first-time users for Tumblr’s mobile app declined 33% year-over-year last quarter.

“Tumblr is one of the Web’s most iconic brands,� Automattic CEO Matt Mullenweg said of the news. “It is an essential venue to share new ideas, cultures and experiences, helping millions create and build communities around their shared interests. We are excited to add it to our lineup, which already includes WordPress .com, WooCommerce, Jetpack, Simplenote, Longreads, and more.�

The news certainly isn’t surprising. In May, it was reported that Verizon was looking for a new owner for the site it inherited through its acquisition of Yahoo. Tumblr was Yahoo’s largest acquisition at the time, as then-CEO Marissa Mayer “promise[d] not to screw it up� in a statement made at the time.

Tumblr proved not to be a great fit for Yahoo — and even less so Verizon, which rolled the platform into its short-lived Oath business and later the Verizon Media Group (also TechCrunch’s umbrella company). On the face of it, at least, Automattic seems a much better match. The company runs WordPress.com, one of the internet’s most popular publishing tools, along with Jetpack and Simplenote. As part of the deal, the company will take on 200 Tumblr staffers.

“We couldn’t be more excited to be joining a team that has a similar mission. Many of you know WordPress.com, Automattic’s flagship product. WordPress.com and Tumblr were both early pioneers among blogging platforms,” Tumblr fittingly wrote in a blog post. “Automattic shares our vision to build passionate communities around shared interests and to democratize publishing so that anyone with a story can tell it, especially when they come from under-heard voices and marginalized communities.”

“Today’s announcement is the culmination of a thoughtful, thorough and strategic process,� Verizon Media CEO Guru Gowrappan said in a statement. “Tumblr is a marquee brand that has started movements, allowed for true identities to blossom and become home to many creative communities and fandoms. We are proud of what the team has accomplished and are happy to have found the perfect partner in Automattic, whose expertise and track record will unlock new and exciting possibilities for Tumblr and its users.�

This hacker’s iPhone charging cable can hijack your computer

Most people don’t think twice about picking up a phone charging cable and plugging it in. But one hacker’s project wants to change that and raise awareness of the dangers of potentially malicious charging cables.

A hacker who goes by the online handle MG took an innocent-looking Apple USB Lightning cable and rigged it with a small Wi-Fi-enabled implant, which, when plugged into a computer, lets a nearby hacker run commands as if they were sitting in front of the screen.

Dubbed the O.MG cable, it looks and works almost indistinguishably from an iPhone charging cable. But all an attacker has to do is swap out the legitimate cable for the malicious cable and wait until a target plugs it into their computer. From a nearby device and within Wi-Fi range (or attached to a nearby Wi-Fi network), an attacker can wirelessly transmit malicious payloads on the computer, either from pre-set commands or an attacker’s own code.

Once plugged in, an attacker can remotely control the affected computer to send realistic-looking phishing pages to a victim’s screen, or remotely lock a computer screen to collect the user’s password when they log back in.

MG focused his first attempt on an Apple Lightning cable, but the implant can be used in almost any cable and against most target computers.

“This specific Lightning cable allows for cross-platform attack payloads, and the implant I have created is easily adapted to other USB cable types,” MG said. “Apple just happens to be the most difficult to implant, so it was a good proof of capabilities.”

In his day job as a red teamer at Verizon Media (which owns TechCrunch), he develops innovative hacking methods and techniques to identify and fix security vulnerabilities before malicious attackers find them. Although a personal project, MG said his malicious cable can help red teamers think about defending against different kinds of threats.

“Suddenly we now have victim-deployed hardware that may not be noticed for much longer periods of time,” he explained. “This changes how you think about defense tactics. We have seen that the NSA has had similar capabilities for over a decade, but it isn’t really in most people’s threat models because it isn’t seen as common enough.”

“Most people know not to plug in random flash drives these days, but they aren’t expecting a cable to be a threat,” he said. “So this helps drive home education that goes deeper.”

MG spent thousands of dollars of his own money and countless hours working on his project. Each cable took him about four hours to assemble. He also worked with several other hackers to write some of the code and develop exploits, and gave away his supply of hand-built cables to Def Con attendees with a plan to sell them online in the near future, he said.

But the O.MG cable isn’t done yet. MG said he’s working with others to improve the cable’s functionality and expand its feature set.

“It really just comes down to time and resources at this point. I have a huge list in my head that needs to become reality,” he said.
