iPhone 14 的 Emergency SOS via satellite (衛星求救服務) 在北美開通

iPhone 14 的 Emergency SOS via satellite 先在北美開通了,包括美國與加拿大地區:「Emergency SOS via satellite available today on the iPhone 14 lineup in the US and Canada」,另外也有提到歐洲的一些區域預定在十二月開通:

iPhone 14 users can now connect with emergency services when cellular and Wi-Fi coverage are not available; the service extends to France, Germany, Ireland, and the UK in December

然後有一些 screenshot 出來了,在沒有 WiFi 與電信訊號的時候打 911 (美國與加拿大的緊急號碼) 會出現透過衛星聯絡的選項:

然後用選擇的方式快速先分類,然後手機要對天空:

這些資訊會先被傳遞,後面緊急聯絡中心可能會再問一些資訊:

另外有提供 satellite demo,可以讓使用者不去打擾緊急聯絡中心的前提下熟悉這套流程:

Using the built-in Emergency SOS via satellite demo, users can test satellite connectivity on their iPhone by connecting to a real satellite in range without calling emergency services, allowing them to experience the process and familiarize themselves with the service.

台灣從五家電信業者的 coverage 資料看起來,五家都沒有覆蓋的地區主要是山區:

目前在台灣類似的功能 (要求救的話) 應該是 Garmin inReach 這個產品線,先前在 YouTube 上有看到開箱...

在南極洲收銀行 OTP 簡訊的方式

看到「SMS Multifactor Authentication in Antarctica」這篇,講在南極洲收銀行 OTP 簡訊的方式 (one-time password,常見的形式是六碼或是七碼數字)。

很明顯的,南極洲沒有什麼電信商可以讓你漫遊 XD

一開始是試著用 Verizon Messages Plus,這個服務可以在電信商直接把簡訊改成 e-mail 寄出來,但作者發現所有的簡訊都會轉送,就是銀行的不會轉送 XDDD

接著是試著用 Google Voice 的號碼,但銀行會判定為 VoIP 電話而不送。

另外的方式是「Wifi Calling」,看起來應該是 VoWiFi 這個台灣更常見的詞,透過 internet 連到電信商的網路掛進去,而不需要透過電信商的基地台。

McMurdo 的網路目前還是有很多不一樣的限制與問題:

At McMurdo, phones have access to a wifi network only for wifi calling and texting, not for general Internet access. It’s just a prototype at this time. It doesn’t work in all cases or in all areas, and for one reason or another it doesn’t work for some people, even if they’ve followed all the steps for enabling wifi calling.

看起來作者遇到的問題是 latency 過高以及頻寬不穩定的問題:

Also, the protocol assumes terrestrial broadband with reasonable latency and bandwidth. At McMurdo, as of this writing, latency to terrestrial locations is in excess of 700 milliseconds. Usable bandwidth for any given end user can vary widely, down to a few dozen kilobits per second.

然後也很難 troubleshooting:

The protocol also doesn’t expose any useful diagnostic info to the end user in order to troubleshoot. You just have to cross your fingers that the magic “wifi calling” icon lights up.

接下來作者嘗試的是 Voice MFA,但不存在這樣的電話號碼可以轉接之類的:

Direct inward dialing to US Antarctic stations isn’t generally available, so you probably can’t configure your cell phone number to forward to a number you can directly answer on-station. (I’m aware of some exceptions to this.)

作者最後提了兩個方法,第一個是想辦法找一個銀行不會擋的虛擬號碼註冊,但這個方法基本上是個貓抓老鼠的遊戲。第二個是作者實做的方法,自己搞 relay,透過 IFTTT 或是其他類似的工具來轉:

轉出來像是這樣:

也許等基礎建設好一點之後,VoWiFi 應該就有機會通?

歐盟 2024 年年底強制使用 USB-C 充電頭 (終於,iPhone...)

Hacker News Daily 上看到「EU Passes Law to Switch iPhone to USB-C by End of 2024」,裡面指到了歐盟的新聞稿:「Long-awaited common charger for mobile devices will be a reality in 2024」。

2024 年年底 (所以是 2025 年) 將強制手機與平板都使用 USB-C 充電頭,2026 年則是延伸涵蓋到筆電:

By the end of 2024, all mobile phones, tablets and cameras sold in the EU will have to be equipped with a USB Type-C charging port. From spring 2026, the obligation will extend to laptops.

終於定案公告了,之前傳言好久了...

Starlink 想要在太空直接提供 5G 網路訊號讓地面手機使用

Hacker News 上看到 Starlink 打算跟 T-Mobile 合作,直接用衛星提供 5G 訊號讓地面手機使用:「SpaceX, T-Mobile to connect satellites to cellphones in remote areas (wsj.com)」,原報導在 WSJ 的「SpaceX, T-Mobile to Connect Satellites to Cellphones in Remote Areas」這邊,另外因為 paywall 的關係,可以在這邊讀。

會用二代衛星:

Mr. Musk said the service would use second-generation Starlink satellites that would be outfitted with large antennas that cover swaths of land that have no service. SpaceX has a pending application before the FCC to launch around 30,000 of the second-generation satellites over time.

在另外一篇報導「SpaceX and T-Mobile team up to use Starlink satellites to ‘end mobile dead zones’」裡面有提到更細一點,不是衛星電話,是目前一般的手機:

The service won’t require mobile users to get a new phone. Musk said in or after a natural disaster, even if all the cell towers are taken out, the planned service should work.

不過可以預期只會有很基本的服務 (大概確保通話與簡訊會通),針對緊急危難狀況會特別有幫助:

Mr. Musk said that the bandwidth would be limited and that the new satellite service wouldn’t supplant existing ground-based cellular services. “This is meant to provide basic coverage to areas that are completely dead,” he said.

翻了翻 wiki,目前 Starlink 第一代衛星的軌道高度是 340km 左右,好像還不確定二代衛星會在哪個高度...

Hacker News 上有蠻多人在算技術上的可行性,除了訊號強度外,衛星與地面相對速度比目前地面上的交通工具都快,都卜勒效應 (Doppler effect) 看起來也是個會影響很多的主題...

不過討論裡面有提到 2021 年就已經有其他商用公司在幹類似的事情,所以看起來不只是講講而已?應該是有些可能性:「Lynk demos global satellite connection for ordinary phones and prepares for commercial launch」。

Apple 在 iOS 16、iPadOS 16 與 macOS Ventura 上推出 Lockdown Mode

AppleiOS 16、iPadOS 16 與 macOS Ventura 上推出了 Lockdown Mode:「Apple expands industry-leading commitment to protect users from highly targeted mercenary spyware」。

Lockdown Mode 主要是透過降低被攻擊的面積以提昇安全性,依照 Apple 的預想,主要是針對被政府單位盯上的族群:

Apple is previewing a groundbreaking security capability that offers specialized additional protection to users who may be at risk of highly targeted cyberattacks from private companies developing state-sponsored mercenary spyware.

在 Lockdown Mode 下目前列出來的限制:

  • Messages: Most message attachment types other than images are blocked. Some features, like link previews, are disabled.
  • Web browsing: Certain complex web technologies, like just-in-time (JIT) JavaScript compilation, are disabled unless the user excludes a trusted site from Lockdown Mode.
  • Apple services: Incoming invitations and service requests, including FaceTime calls, are blocked if the user has not previously sent the initiator a call or request.
  • Wired connections with a computer or accessory are blocked when iPhone is locked.
  • Configuration profiles cannot be installed, and the device cannot enroll into mobile device management (MDM), while Lockdown Mode is turned on.

列出來的這些的確都是之前 0-day 常被拿來打的東西,把攻擊面積縮小的確會有不少幫助。

這應該是業界第一個大咖跳進來做這個 (也就兩個大咖?),第一次搞未必會完美,但算是個開始,後面應該會有更多的面積被考慮進去...

不使用 Google 服務的 Android 手機

一樣是在 Lobsters Daily 上翻到的,去 Google 服務的 Android 系統搞法:「Lineage with microG on a Sony XA2」。

主要是看關鍵字的部份,TWRP 換掉 recovery image,然後 LineageOS 是系統底,microG 是 open source 版本的 Google 專屬 API 的相容層,Magisk 則是負責 root 相關的事情,F-Droid 是 open source 軟體的 app store,可以用他來裝 Aurora Store,就可以裝 Play Store 裡的 app。

會這樣搞的人主要還是考慮到 privacy,可以預期有不少應用程式是不會動的...

Facebook 5.33 億筆個資外洩,以及 Mark Zuckerberg 的電話...

這兩天應該已經有很多其他媒體報導了 Facebook 5.33 億筆資料外洩的事情:「533 million Facebook users' phone numbers and personal data have been leaked online」。

據稱是用 2019 年的洞撈出來的,不過這份資料看起來也不是完整資料,舉個例子來說,台灣只有 73 萬筆左右,而且也少了很多地區,像是泰國就不在列表內...

另外一個比較特別的是,Mark Zuckerberg 的電話也在這次外洩資料裡面:「Mark Zuckerberg's phone number appeared among the leaked data of Facebook users, according to a researcher」,應該會換號碼了。

這包資料看起來會這陣子會很熱門...

FBI 手上的 GrayKey 可以解 iPhone 11 Pro Max

在「FBI Successfully Unlocks iPhone 11 Pro in Ohio, Casting Doubt on Claims it Needs Apple's Help in Florida Mass Shooter Case」這邊看到的消息,看起來 FBI 手上的 GrayKey 可以解開 iPhone 11 Pro Max 了...

先前 GrayKey 只有舊型的可以解,像是之前揭露的 iPhone 5 或是 iPhone 7,現在看起來找到新的漏洞可以打穿新的版本,所以升級了:

Forbes has previously revealed a GrayKey brochure that showed it worked on older devices, and the two iPhones acquired by the FBI in the most recent Pensacola case are an ‌iPhone‌ 5 and an ‌iPhone‌ 7, which strongly suggests that investigators are already capable of unlocking them.

魔與道的競爭...

幫你的 iPhone 電話簿找到對應的頭像

前幾天看到的:「Announcing Vignette」,透過 social network 的資料,把本來電話簿裡面的 icon 更新:

透過 app store 的搜尋找不太到,我一開始用了「Vignette」搜不到,但用「Vignette Update」就可以。或者你可以透過他提供的連結直接開 app store:「Vignette – Update Contact Pics」。

這是一個 IAP 類的付費服務,搜尋是免費的,但如果要把資料更新回通訊錄,需要付 USD$4.99 (一次性),台灣帳號是付 TWD$170,應該是因為最近的稅務調整:

Vignette allows you to scan your contacts and see what it can find for free. If you wish to actually save these updates to your contact list, you must pay for a one-time in-app purchase. That purchase costs $4.99, is not a subscription, and is the only in-app purchase.

搜尋的範圍包括了 GravatarTwitterFacebookInstagram

Email is used for Gravatar
Twitter
Facebook
A custom network called Instagram

另外作者有提到這個 app 不傳資料到伺服器上,都是在自己的裝置上連到上面提到的 social network 尋找:

Privacy is paramount
All the processing is done on-device; this isn’t the sort of app where your contacts are uploaded en masse to some server, and out of your control.

所以速度不會太快,但對隱私比較好...
