RentPath drops acquisition deal with CoStar after FTC antitrust lawsuit

Published

on

RentPath, owner of property listing sites including Rent.com and Apartment Guide, said today it has cancelled its agreement to be acquired by CoStar Group after the Federal Trade Commission sued to block the sale.

CoStar, a commercial real estate data and analytics provider that also operates listing sites like Apartments.com and ApartmentFinder.com, agreed in February to buy RentPath for $588 million. The all-cash deal came after RentPath said it would file for chapter 11 bankruptcy protection. RentPath had already hired financial advisors to restructure more than $650 million in debt, reported the Wall Street Journal.

But earlier this month, the Federal Trade Commission authorized an antitrust lawsuit in federal court to block the acquisition. Daniel Francis, deputy director of the FTC’s Bureau of Competition, said in a statement that “the acquisition will eliminate price and quality competition that benefits both renters and property managers,” because CoStar and RentPath’s rivalry kept advertising rates on their platform, which include some of the most popular listing sites, low.

In its announcement today, RentPath said its chapter 11 plan remains backed by lenders, including alternative asset management firms with “strong track records of successfully investing in businesses under similar circumstances.”

The FTC’s lawsuit and RentPath’s decision to back out of the acquisition agreement comes as more countries around the world are cracking down on tech consolidation. While the United States has trailed behind other governments in terms of antitrust actions, that is gradually changing, with Amazon, Google and Facebook coming under more legislative scrutiny, and the recent lawsuit filed by 46 states against Facebook alleging that it bought competitors “illegally” to increase its market power.

The fate of the RentPath/CoStar deal may foreshadow more antitrust scrutiny for proptech companies in the United States, too. CoStar built out its business over the past decade through acquisitions and has other deals currently in the works, including listings site HomeSnap, which passed FTC review last month, and a reported bid for property analytics company CoreLogic. CoStar and RentPath competitor Zillow is also known for building its business through a series of acquisitions, including Trulia for $3.5 billion in 2014.

Teach AIs forgetfulness could make them better at their jobs

Published

on

While modern machine learning systems act with a semblance of artificial intelligence, the truth is they don’t “understand” any of the data they work with — which in turn means they tend to store even trivial items forever. Facebook researchers have proposed structured forgetfulness as a way for AI to clear the decks a bit, improving their performance and inching that much closer to how a human mind works.

The researchers describe the problem by explaining how humans and AI agents might approach a similar problem.

Say there are ten doors of various colors. You’re asked to go through the yellow one, you do so and then a few minutes later have forgotten the colors of the other doors — because it was never important that two were red, one plaid, two walnut, etc, only that they weren’t yellow and that the one you chose was. Your brain discarded that information almost immediately.

But an AI might very well have kept the colors and locations of the other nine doors in its memory. That’s because it doesn’t understand the problem or the data intuitively — so it keeps all the information it used to make its decision.

This isn’t an issue when you’re talking about relatively small amounts of data, but machine learning algorithms, especially during training, now routinely handle millions of data points and ingest terabytes of imagery or language. And because they’re built to constantly compare new data with their accrued knowledge, failing to forget unimportant things means they’re bogged down by constant references to pointless or outdated data points.

The solution hit upon by Facebook researchers is essentially — and wouldn’t we all like to have this ability — to tell itself how long it needs to remember a piece of data when it evaluates it to begin with.

“Each individual memory is associated with a predicted expiration date, and the scale of the memory depends on the task,” explained Angela Fan, a Facebook AI researcher who worked on the Expire-Span paper. “The amount of time memories are held depends on the needs of the task—it can be for a few steps or until the task is complete.”

So in the case of the doors, the colors of the non-yellow doors are plenty important until you find the yellow one. At that point it’s safe to forget the rest, though of course depending on how many other doors need to be checked, the memory could be held for various amounts of time. (A more realistic example might be forgetting faces that aren’t the one the system is looking for, once it finds it.)

Analyzing a long piece of text, the memory of certain words or phrases might matter until the end of a sentence, a paragraph, or longer — it depends on whether the agent is trying to determine who’s speaking, what chapter the sentence belongs to, or what genre the story is.

This improves performance because at the end, there’s simply less information for the model to sort through. Because the system doesn’t know whether the other doors might be important, that information is kept ready at hand, increasing the size and decreasing the speed of the model.

Fan said the models trained using Expire-Span performed better and were more efficient, taking up less memory and compute time. That’s important during training and testing, which can take up thousands of hours of processing, meaning even a small improvement is considerable, but also at the end user level, where the same task takes less power and happens faster. Suddenly performing an operation on a photo makes sense to do live rather than after the fact.

Though being able to forget does in some ways bring AI processes closer to human cognition, it’s still nowhere near the intuitive and subtle ways our minds operate. Of course, being able to pick what to remember and how long is a major advantage over those of us for whom those parameters are chosen seemingly randomly.

Echelon exposed riders’ account data, thanks to a leaky API

Peloton wasn’t the only at-home workout giant exposing private account data. Rival exercise giant Echelon also had a leaky API that let virtually anyone access riders’ account information.

Fitness technology company Echelon, like Peloton, offers a range of workout hardware — bikes, rowers, and a treadmill — as a cheaper alternative for members to exercise at home. Its app also lets members join virtual classes without the need for workout equipment.

But Jan Masters, a security researcher at Pen Test Partners, found that Echelon’s API allowed him to access the account data — including name, city, age, sex, phone number, weight, birthday, and workout statistics and history — of any other member in a live or pre-recorded class. The API also disclosed some information about members’ workout equipment, such as its serial number.

Masters, if you recall, found a similar bug with Peloton’s API, which let him make unauthenticated requests and pull private user account data directly from Peloton’s servers without the server ever checking to make sure he (or anyone else) was allowed to request it.

Echelon’s API allows its members’ devices and apps to talk with Echelon’s servers over the internet. The API was supposed to check if the member’s device was authorized to pull user data by checking for an authorization token. But Masters said the token wasn’t needed to request data.

Masters also found another bug that allowed members to pull data on any other member because of weak access controls on the API. Masters said this bug made it easy to enumerate user account IDs and scrape account data from Echelon’s servers. Facebook, LinkedIn, Peloton and Clubhouse have all fallen victim to scraping attacks that abuse access to APIs to pull in data about users on their platforms.

Ken Munro, founder of Pen Test Partners, disclosed the vulnerabilities to Echelon on January 20 in a Twitter direct message, since the company doesn’t have a public-facing vulnerability disclosure process (which it says is now “under review”). But the researchers did not hear back during the 90 days after the report was submitted, the standard amount of time security researchers give companies to fix flaws before their details are made public.

TechCrunch asked Echelon for comment, and was told that the security flaws identified by Masters — which he wrote up in a blog post — were fixed in January.

“We hired an outside service to perform a penetration test of systems and identify vulnerabilities. We have taken appropriate actions to correct these, most of which were implemented by January 21, 2021. However, Echelon’s position is that the User ID is not PII [personally identifiable information,” said Chris Martin, Echelon’s chief information security officer, in an email.

Echelon did not name the outside security company but said while the company said it keeps detailed logs, it did not say if it had found any evidence of malicious exploitation.

But Munro disputed the company’s claim of when it fixed the vulnerabilities, and provided TechCrunch with evidence that one of the vulnerabilities was not fixed until at least mid-April, and another vulnerability could still be exploited as recently as this week.

When asked for clarity, Echelon did not address the discrepancies. “[The security flaws] have been remediated,” Martin reiterated.

Echelon also confirmed it fixed a bug that allowed users under the age of 13 to sign up. Many companies block access to children under the age of 13 to avoid complying with the Children’s Online Privacy Protection Act, or COPPA, a U.S. law that puts strict rules on what data companies can collect on children. TechCrunch was able to create an Echelon account this week with an age less than 13, despite the page saying: “Minimum age of use is 13 years old.”
