China’s Olympics App Is Horribly Insecure

China is mandating that athletes download and use a health and travel app when they attend the Winter Olympics next month. Citizen Lab examined the app and found it riddled with security holes.

Key Findings:

  • MY2022, an app mandated for use by all attendees of the 2022 Olympic Games in Beijing, has a simple but devastating flaw where encryption protecting users’ voice audio and file transfers can be trivially sidestepped. Health customs forms which transmit passport details, demographic information, and medical and travel history are also vulnerable. Server responses can also be spoofed, allowing an attacker to display fake instructions to users.
  • MY2022 is fairly straightforward about the types of data it collects from users in its public-facing documents. However, as the app collects a range of highly sensitive medical information, it is unclear with whom or which organization(s) it shares this information.
  • MY2022 includes features that allow users to report “politically sensitive” content. The app also includes a censorship keyword list, which, while presently inactive, targets a variety of political topics including domestic issues such as Xinjiang and Tibet as well as references to Chinese government agencies.
  • While the vendor did not respond to our security disclosure, we find that the app’s security deficits may not only violate Google’s Unwanted Software Policy and Apple’s App Store guidelines but also China’s own laws and national standards pertaining to privacy protection, providing potential avenues for future redress.

News article:

It’s not clear whether the security flaws were intentional or not, but the report speculated that proper encryption might interfere with some of China’s ubiquitous online surveillance tools, especially systems that allow local authorities to snoop on phones using public wireless networks or internet cafes. Still, the researchers added that the flaws were probably unintentional, because the government will already be receiving data from the app, so there wouldn’t be a need to intercept the data as it was being transferred.

[…]

The app also included a list of 2,422 political keywords, described within the code as “illegalwords.txt,” that worked as a keyword censorship list, according to Citizen Lab. The researchers said the list appeared to be a latent function that the app’s chat and file transfer function was not actively using.

The US government has already advised athletes to leave their personal phones and laptops home and bring burners.

Are Fake COVID Testing Sites Harvesting Data?

Over the past few weeks, I’ve seen a bunch of writing about what seems to be fake COVID-19 testing sites. They take your name and info, and do a nose swab, but you never get test results. Speculation centered around data harvesting, but that didn’t make sense because it was far too labor intensive for that and—sorry to break it to you—your data isn’t worth all that much.

It seems to be multilevel marketing fraud instead:

The Center for COVID Control is a management company to Doctors Clinical Laboratory. It provides tests and testing supplies, software, personal protective equipment and marketing services—online and printed—to testing sites, said a person who was formerly associated with the Center for COVID Control. Some of the sites are owned independently but operate in partnership with the chain under its name and with its guidance.

[…]

Doctors Clinical Lab, the lab Center for COVID Control uses to process tests, makes money by billing patients’ insurance companies or seeking reimbursement from the federal government for testing. Insurance statements reviewed by Block Club show the lab has, in multiple instances, billed insurance companies $325 for a PCR test, $50 for a rapid test, $50 for collecting a person’s sample and $80 for a “supplemental fee.”

In turn, the testing sites are paid for providing samples to the lab to be processed, said a person formerly associated with the Center for COVID Control.

In a January video talking to testing site operators, Syed said the Center for COVID Control will no longer provide them with PCR tests, but it will continue supplying them with rapid tests at a cost of $5 per test. The companies will keep making money for the rapid tests they collect, he said.

“You guys will continue making the $28.50 you’re making for the rapid test,” Syed said in the video.

Read the article for the messy details. Or take a job and see for yourself.

EDITED TO ADD (2/13): More coverage about the fake testing sites.

ProtonMail Now Keeps IP Logs

After being compelled by a Swiss court to monitor IP logs for a particular user, ProtonMail no longer claims that “we do not keep any IP logs.”

EDITED TO ADD (9/14): This seems to be more complicated. ProtonMail is not yet saying that they keep logs. Their privacy policy still states that they do not keep logs except in certain circumstances, and outlines those circumstances. And ProtonMail’s warrant canary has an interesting list of data orders they have received from various authorities, whether they complied, and why or why not.

De-anonymization Story

This is important:

Monsignor Jeffrey Burrill was general secretary of the US Conference of Catholic Bishops (USCCB), effectively the highest-ranking priest in the US who is not a bishop, before records of Grindr usage obtained from data brokers was correlated with his apartment, place of work, vacation home, family members’ addresses, and more.

[…]

The data that resulted in Burrill’s ouster was reportedly obtained through legal means. Mobile carriers sold­—and still sell—­location data to brokers who aggregate it and sell it to a range of buyers, including advertisers, law enforcement, roadside services, and even bounty hunters. Carriers were caught in 2018 selling real-time location data to brokers, drawing the ire of Congress. But after carriers issued public mea culpas and promises to reform the practice, investigations have revealed that phone location data is still popping up in places it shouldn’t. This year, T-Mobile even broadened its offerings, selling customers’ web and app usage data to third parties unless people opt out.

The publication that revealed Burrill’s private app usage, The Pillar, a newsletter covering the Catholic Church, did not say exactly where or how it obtained Burrill’s data. But it did say how it de-anonymized aggregated data to correlate Grindr app usage with a device that appears to be Burrill’s phone.

The Pillar says it obtained 24 months’ worth of “commercially available records of app signal data” covering portions of 2018, 2019, and 2020, which included records of Grindr usage and locations where the app was used. The publication zeroed in on addresses where Burrill was known to frequent and singled out a device identifier that appeared at those locations. Key locations included Burrill’s office at the USCCB, his USCCB-owned residence, and USCCB meetings and events in other cities where he was in attendance. The analysis also looked at other locations farther afield, including his family lake house, his family members’ residences, and an apartment in his Wisconsin hometown where he reportedly has lived.

Location data is not anonymous. It cannot be made anonymous. I hope stories like these will teach people that.

Commercial Location Data Used to Out Priest

A Catholic priest was outed through commercially available surveillance data. Vice has a good analysis:

The news starkly demonstrates not only the inherent power of location data, but how the chance to wield that power has trickled down from corporations and intelligence agencies to essentially any sort of disgruntled, unscrupulous, or dangerous individual. A growing market of data brokers that collect and sell data from countless apps has made it so that anyone with a bit of cash and effort can figure out which phone in a so-called anonymized dataset belongs to a target, and abuse that information.

There is a whole industry devoted to re-identifying anonymized data. This was something that Snowden showed that the NSA could do. Now it’s available to everyone.

Changes in WhatsApp’s Privacy Policy

If you’re a WhatsApp user, pay attention to the changes in the privacy policy that you’re being forced to agree with.

In 2016, WhatsApp gave users a one-time ability to opt out of having account data turned over to Facebook. Now, an updated privacy policy is changing that. Come next month, users will no longer have that choice. Some of the data that WhatsApp collects includes:

  • User phone numbers
  • Other people’s phone numbers stored in address books
  • Profile names
  • Profile pictures and
  • Status message including when a user was last online
  • Diagnostic data collected from app logs

Under the new terms, Facebook reserves the right to share collected data with its family of companies.

EDITED TO ADD (1/13): WhatsApp tries to explain.

The US Military Buys Commercial Location Data

Vice has a long article about how the US military buys commercial location data worldwide.

The U.S. military is buying the granular movement data of people around the world, harvested from innocuous-seeming apps, Motherboard has learned. The most popular app among a group Motherboard analyzed connected to this sort of data sale is a Muslim prayer and Quran app that has more than 98 million downloads worldwide. Others include a Muslim dating app, a popular Craigslist app, an app for following storms, and a “level” app that can be used to help, for example, install shelves in a bedroom.

This isn’t new, this isn’t just data of non-US citizens, and this isn’t the US military. We have lots of instances where the government buys data that it cannot legally collect itself.

Some app developers Motherboard spoke to were not aware who their users’ location data ends up with, and even if a user examines an app’s privacy policy, they may not ultimately realize how many different industries, companies, or government agencies are buying some of their most sensitive data. U.S. law enforcement purchase of such information has raised questions about authorities buying their way to location data that may ordinarily require a warrant to access. But the USSOCOM contract and additional reporting is the first evidence that U.S. location data purchases have extended from law enforcement to military agencies.

On Executive Order 12333

Mark Jaycox has written a long article on the US Executive Order 12333: “No Oversight, No Limits, No Worries: A Primer on Presidential Spying and Executive Order 12,333“:

Abstract: Executive Order 12,333 (“EO 12333”) is a 1980s Executive Order signed by President Ronald Reagan that, among other things, establishes an overarching policy framework for the Executive Branch’s spying powers. Although electronic surveillance programs authorized by EO 12333 generally target foreign intelligence from foreign targets, its permissive targeting standards allow for the substantial collection of Americans’ communications containing little to no foreign intelligence value. This fact alone necessitates closer inspection.

This working draft conducts such an inspection by collecting and coalescing the various declassifications, disclosures, legislative investigations, and news reports concerning EO 12333 electronic surveillance programs in order to provide a better understanding of how the Executive Branch implements the order and the surveillance programs it authorizes. The Article pays particular attention to EO 12333’s designation of the National Security Agency as primarily responsible for conducting signals intelligence, which includes the installation of malware, the analysis of internet traffic traversing the telecommunications backbone, the hacking of U.S.-based companies like Yahoo and Google, and the analysis of Americans’ communications, contact lists, text messages, geolocation data, and other information.

After exploring the electronic surveillance programs authorized by EO 12333, this Article proposes reforms to the existing policy framework, including narrowing the aperture of authorized surveillance, increasing privacy standards for the retention of data, and requiring greater transparency and accountability.

EDITED TO ADD (10/12): Good New York Times article from 1983 on EO 12333, pointing out that Congress had never limited its power. It still hasn’t.

And a related article on the FISA Court.

Cory Doctorow on The Age of Surveillance Capitalism

Cory Doctorow has writtten an extended rebuttal of The Age of Surveillance Capitalism by Shoshana Zuboff. He summarized the argument on Twitter.

Shorter summary: it’s not the surveillance part, it’s the fact that these companies are monopolies.

I think it’s both. Surveillance capitalism has some unique properties that make it particularly unethical and incompatible with a free society, and Zuboff makes them clear in her book. But the current acceptance of monopolies in our society is also extremely damaging—which Doctorow makes clear.
