Bypassing Apple’s AirTag Security

A Berlin-based company has developed an AirTag clone that bypasses Apple’s anti-stalker security systems. Source code for these AirTag clones is available online.

So now we have several problems with the system. Apple’s anti-stalker security only works with iPhones. (Apple wrote an Android app that can detect AirTags, but how many people are going to download it?) And now non-AirTags can piggyback on Apple’s system without triggering the alarms.

Apple didn’t think this through nearly as well as it claims to have. I think the general problem is one that I have written about before: designers just don’t have intimate threats in mind when building these systems.

A New Cybersecurity “Social Contract”

The US National Cyber Director Chris Inglis wrote an essay outlining a new social contract for the cyber age:

The United States needs a new social contract for the digital age—one that meaningfully alters the relationship between public and private sectors and proposes a new set of obligations for each. Such a shift is momentous but not without precedent. From the Pure Food and Drug Act of 1906 to the Clean Air Act of 1963 and the public-private revolution in airline safety in the 1990s, the United States has made important adjustments following profound changes in the economy and technology.

A similarly innovative shift in the cyber-realm will likely require an intense process of development and iteration. Still, its contours are already clear: the private sector must prioritize long-term investments in a digital ecosystem that equitably distributes the burden of cyberdefense. Government, in turn, must provide more timely and comprehensive threat information while simultaneously treating industry as a vital partner. Finally, both the public and private sectors must commit to moving toward true collaboration—contributing resources, attention, expertise, and people toward institutions designed to prevent, counter, and recover from cyber-incidents.

The devil is in the details, of course, but he’s 100% right when he writes that the market cannot solve this: that the incentives are all wrong. While he never actually uses the word “regulation,” the future he postulates won’t be possible without it. Regulation is how society aligns market incentives with its own values. He also leaves out the NSA—whose effectiveness rests on all of these global insecurities—and the FBI, whose incessant push for encryption backdoors goes against his vision of increased cybersecurity. I’m not sure how he’s going to get them on board. Or the surveillance capitalists, for that matter. A lot of what he wants will require reining in that particular business model.

Good essay—worth reading in full.

Stealing Bicycles by Swapping QR Codes

This is a clever hack against those bike-rental kiosks:

They’re stealing Citi Bikes by switching the QR scan codes on two bicycles near each other at a docking station, then waiting for an unsuspecting cyclist to try to unlock a bike with his or her smartphone app.

The app doesn’t work for the rider but does free up the nearby Citi Bike with the switched code, where a thief is waiting, jumps on the bicycle and rides off.

Presumably they’re using camera, printers, and stickers to swap the codes on the bikes. And presumably the victim is charged for not returning the stolen bicycle.

This story is from last year, but I hadn’t seen it before. There’s a video of one theft at the link.

Friday Squid Blogging: South American Squid Stocks Threatened by Chinese Fishing

There’s a lot of fishing going on:

The number of Chinese-flagged vessels in the south Pacific has surged 13-fold from 54 active vessels in 2009 to 707 in 2020, according to the SPRFMO. Meanwhile, the size of China’s squid catch has grown from 70,000 tons in 2009 to 358,000.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Possible Government Surveillance of the Otter.ai Transcription App

A reporter interviews a Uyghur human-rights advocate, and uses the Otter.ai transcription app.

The next day, I received an odd note from Otter.ai, the automated transcription app that I had used to record the interview. It read: “Hey Phelim, to help us improve your Otter’s experience, what was the purpose of this particular recording with titled ‘Mustafa Aksu’ created at ‘2021-11-08 11:02:41’?”

Customer service or Chinese surveillance? Turns out it’s hard to tell.

EDITED TO ADD (3/12): Another article.

Vendors are Fixing Security Flaws Faster

Google’s Project Zero is reporting that software vendors are patching their code faster.

tl;dr

  • In 2021, vendors took an average of 52 days to fix security vulnerabilities reported from Project Zero. This is a significant acceleration from an average of about 80 days 3 years ago.
  • In addition to the average now being well below the 90-day deadline, we have also seen a dropoff in vendors missing the deadline (or the additional 14-day grace period). In 2021, only one bug exceeded its fix deadline, though 14% of bugs required the grace period.
  • Differences in the amount of time it takes a vendor/product to ship a fix to users reflects their product design, development practices, update cadence, and general processes towards security reports. We hope that this comparison can showcase best practices, and encourage vendors to experiment with new policies.
  • This data aggregation and analysis is relatively new for Project Zero, but we hope to do it more in the future. We encourage all vendors to consider publishing aggregate data on their time-to-fix and time-to-patch for externally reported vulnerabilities, as well as more data sharing and transparency in general.

On the Irish Health Services Executive Hack

A detailed report of the 2021 ransomware attack against Ireland’s Health Services Executive lists some really bad security practices:

The report notes that:

  • The HSE did not have a Chief Information Security Officer (CISO) or a “single responsible owner for cybersecurity at either senior executive or management level to provide leadership and direction.
  • It had no documented cyber incident response runbooks or IT recovery plans (apart from documented AD recovery plans) for recovering from a wide-scale ransomware event.
  • Under-resourced Information Security Managers were not performing their business as usual role (including a NIST-based cybersecurity review of systems) but were working on evaluating security controls for the COVID-19 vaccination system. Antivirus software triggered numerous alerts after detecting Cobalt Strike activity but these were not escalated. (The antivirus server was later encrypted in the attack).
  • There was no security monitoring capability that was able to effectively detect, investigate and respond to security alerts across HSE’s IT environment or the wider National Healthcare Network (NHN).
  • There was a lack of effective patching (updates, bug fixes etc.) across the IT estate and reliance was placed on a single antivirus product that was not monitored or effectively maintained with updates across the estate. (The initial workstation attacked had not had antivirus signatures updated for over a year.)
  • Over 30,000 machines were running Windows 7 (out of support since January 2020).
  • The initial breach came after a HSE staff member interacted with a malicious Microsoft Office Excel file attached to a phishing email; numerous subsequent alerts were not effectively investigated.

PwC’s crisp list of recommendations in the wake of the incident ­ as well as detail on the business impact of the HSE ransomware attack ­ may prove highly useful guidance on best practice for IT professionals looking to set up a security programme and get it funded.
