# Mars 2022
|
||||
|
||||
On March 20, 2022, my parents finds a partially buried phone in the
|
||||
snow, in Tignes. A shiny iPhone 12 Pro Max, in prinstine condition for
|
||||
a phone lost on a ski slope where many people could have skied on it!
|
||||
|
||||
Step 0: The phone is discharged, my parents don't have the proper
|
||||
cables, so they try a wireless charger and it works, YAY!
|
||||
|
||||
Step 1: As it's not the first time they find a phone, [they know how
|
||||
to quickly find the owner
|
||||
back](https://twitter.com/sizeof/status/1217469079356874754), they try
|
||||
to unlock it, no luck, it's a 5 or 6 digit code, so they just wait for
|
||||
someone to call: should take from a few minutes to a few hours.
|
||||
|
||||
But nobody gonna call: the SIM card is locked!
|
||||
|
||||
The next day I receive a message from my parents:
|
||||
|
||||
> Yesterday I found a nice Phone, I charged it, but nobody calls, what should I do?
|
||||
|
||||
I ask for some pictures, to identify the phone.
|
||||
|
||||
Step 3: I'm guiding them to the "Medical ID" info (behind the Emergency thing).
|
||||
|
||||
But there's no medical ID on this phone.
|
||||
|
||||
Hey people, do fill the medical ID, like right now, while you're
|
||||
reading this article. It exists on Android too, it's called "Emergency
|
||||
information", and it really helps finding you back when you loose your
|
||||
phone.
|
||||
|
||||
I try to guide them to spawning Siri to ask some info about the
|
||||
owner, but with no luck (looks like it's not possible while the phone
|
||||
has not been unlocked or something like this).
|
||||
|
||||
As said in step 1, the phone is properly locked, which is a very good
|
||||
idea, even if in the past my parents quickly found the owner of a lost
|
||||
unlocked phone just calling back the last number in the call
|
||||
history. Do properly lock your phone. And no, `0000` is not a proper
|
||||
password.
|
||||
|
||||
Step 4: I don't know what to do remotely then… so I tell them to give
|
||||
it to the "lost and found" place in Tignes and hope for the best.
|
||||
|
||||
I tried to shoot [a tweets about
|
||||
it](https://twitter.com/sizeof/status/1506252615931375617), but with
|
||||
no luck.
|
||||
|
||||
|
||||
# June 2022
|
||||
|
||||
I went to see my parents and they remember me the lost iPhone, I ask
|
||||
about the phone not being given to the "lost and found" desk, they say
|
||||
no (hey Tignes, next time be polite to people coming to the lost and
|
||||
found desk... it would help).
|
||||
|
||||
So I'm back at it again, there's literally nothing interesting to do
|
||||
via the OS so I'm opening the SIM card slot:
|
||||
|
||||
- Got an IMEI from the SIM card slot, probably unhelpfull... It
|
||||
confirms the phone model I already know, it tells me the "Find My
|
||||
Phone" is enabled on it, but I have nothing more to learn here,
|
||||
looks like a dead end.
|
||||
- Got a operator logo (Free) on the SIM card.
|
||||
- Got a 15 digits number from the SIM card, probably helpfull!
|
||||
|
||||
The number was 15 chars long, not enough to be an ICCID… but according
|
||||
to Wikipedia the ICCID may start with `89`:
|
||||
|
||||
> Major industry identifier (MII), 2 fixed digits, 89 for telecommunication purposes.
|
||||
|
||||
And as it's a french operator, it may be followed by `33` (the country code).
|
||||
|
||||
So prefixing with `8933` I have a probably valid ICCID!
|
||||
|
||||
Step 5: I call `free` (ooohhh it's hard to get to tell to a human and
|
||||
not a robot...) and ask them info about this ICCID, which they reply
|
||||
they don't know this ICCID at all... Obviously the SIM was revoked,
|
||||
and sadly they don't keep info on revoked SIM cards, at least not in
|
||||
this DB.
|
||||
|
||||
The guy was very sorry not being able to help, he told me the only way
|
||||
I had left is to give it to the police, but I told him I prefer
|
||||
finding the owner myself to ensure it's done, which he completly
|
||||
agreed.
|
||||
|
||||
OK let's stop trying the normal way, let's try the hard way! The SIM
|
||||
card is locked and revoked, I have 3 tries for the PIN number which I
|
||||
guess is either the default one (`1234` for this operator), or `0000`
|
||||
or I don't know, `0123` maybe?
|
||||
|
||||
So I plug the SIM card on my phone (it's a Pinephone with Mobian on
|
||||
it), hoping to be able to unlock it and dump some data like:
|
||||
|
||||
- Contact list,
|
||||
- Last call journal,
|
||||
- SMS,
|
||||
- Whatever I don't care just give me a lead...
|
||||
|
||||
I'm no expert with `AT commands`, I just now they exist, it should be enough right?
|
||||
|
||||
Booted my Pinephone, and knowing it would be long I sshed on it from
|
||||
my laptop to buy me some comfort:
|
||||
|
||||
```
|
||||
$ ssh mobian@mobian.local
|
||||
```
|
||||
|
||||
Because yes, I can SSH to my phone, and no I did not changed the
|
||||
default user. But yes I disabled the password login for SSHD and only
|
||||
log via my Yubikey.
|
||||
|
||||
Next I ran `gnome-session-inhibit bash`: I don't want the phone to
|
||||
suspend while I'm working on it... It's very comfy for me to have a
|
||||
real Debian on my phone: feels like working on a laptop.
|
||||
|
||||
OK let's start for real!!
|
||||
|
||||
```
|
||||
$ mmcli -m any
|
||||
[...it's a long output so here's the relevant part...]
|
||||
-----------------------------------
|
||||
Status | state: failed
|
||||
| failed reason: sim-missing
|
||||
| power state: on
|
||||
| signal quality: 0% (cached)
|
||||
-----------------------------------
|
||||
[...it's a long output so here's the relevant part...]
|
||||
```
|
||||
|
||||
What? Oh damned, the SIM card is not properly installed in its slot...
|
||||
And on a Pinpheon when you want to remove the SIM you have to remove
|
||||
the battery...
|
||||
|
||||
OK let's start again from scratch and:
|
||||
|
||||
```
|
||||
$ mmcli -m any
|
||||
[...it's a long output so here's the relevant part...]
|
||||
-----------------------------------
|
||||
Status | lock: sim-pin
|
||||
| unlock retries: sim-pin (3), sim-puk (10), sim-pin2 (3), sim-puk2 (10)
|
||||
| state: locked
|
||||
| power state: on
|
||||
| signal quality: 0% (cached)
|
||||
-----------------------------------
|
||||
[...it's a long output so here's the relevant part...]
|
||||
```
|
||||
|
||||
Hello SIM card, so you're locked?
|
||||
|
||||
```
|
||||
$ mmcli -m any -i 0 --pin 1234
|
||||
successfully sent PIN code to the SIM
|
||||
```
|
||||
|
||||
```
|
||||
$ mmcli -m any
|
||||
[...it's a long output so I redacted it...]
|
||||
-----------------------------------
|
||||
Status | lock: sim-pin2
|
||||
| unlock retries: sim-pin (3), sim-puk (10), sim-pin2 (3), sim-puk2 (10)
|
||||
| state: enabled
|
||||
| power state: on
|
||||
| signal quality: 0% (cached)
|
||||
-----------------------------------
|
||||
[...it's a long output so I redacted it...]
|
||||
```
|
||||
|
||||
Yeah, I like when it finally starts to be easy! So what can I get from
|
||||
this SIM card? The `CPBS` commands is to choose the storage of phone
|
||||
book memory, and `SM` is for `SIM Phonebook`:
|
||||
|
||||
```
|
||||
$ mmcli -m any --command='AT+CPBS=?'
|
||||
response: '+CPBS: ("SM","DC","MC","ME","RC","EN")'
|
||||
$ mmcli -m any --command='AT+CPBS="SM"'
|
||||
response: ''
|
||||
```
|
||||
|
||||
OK there's a SIM Phonebook and we just choosen it, let's read it using `CPBR` (`R` for `Read`)
|
||||
|
||||
```
|
||||
$ mmcli -m any --command='AT+CPBR=?'
|
||||
response: '+CPBR: (1-250),40,14'
|
||||
$ mmcli -m any --command='AT+CPBR=1'
|
||||
error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.MobileEquipment.NotFound: Not found'
|
||||
```
|
||||
|
||||
Damned, no contacts in the phone book... Which is probably very normal
|
||||
for an iPhone, but if you don't try, you don't know...
|
||||
|
||||
OK let's try to read some SMS messages then:
|
||||
|
||||
```
|
||||
$ mmcli -m any --command='AT+CMGF=1'
|
||||
response: ''
|
||||
$ mmcli -m any --command='AT+CMGL="ALL"'
|
||||
response: ''
|
||||
```
|
||||
|
||||
Damned, nothing here neither.
|
||||
|
||||
Out of idea I start doodling around...
|
||||
|
||||
...trying `mmcli -m any` again, remember it was a long output and I
|
||||
readacted for your readability? I read it fully once, but before
|
||||
unlocking the SIM, I went to read it fully a second time and BOOM a
|
||||
section appeared since I unlocked the card:
|
||||
|
||||
```
|
||||
-----------------------------------
|
||||
Numbers | own: 3365xxxxxxx
|
||||
-----------------------------------
|
||||
```
|
||||
|
||||
(Obviously there was no `x`s, only a real phone number, redacted for the owner privacy.)
|
||||
|
||||
I immediatly called the number (using a landline phone, remember, my
|
||||
mobile phone had its guts open with another SIM card in it), got no
|
||||
response, dropped a weird, completly unprepared message on his voice
|
||||
mail, like:
|
||||
|
||||
> Hey you may have lost an IPhone, I may have found it, write me an email at julien@palard.fr!
|
||||
|
||||
From my point of view I was not 100% sure to find the right owner, so
|
||||
the less info I would give, the more info I could ask to validate it's
|
||||
the right person!
|
||||
|
||||
Gave my email instead of my phone number because... I still had to put
|
||||
my SIM card in my phone... and I don't know my own landfill number...
|
||||
|
||||
I bet if I receive this message all my scam alerts goes red. All his
|
||||
scam alerts went red but he called back a few minutes later (after
|
||||
all, he really lost an iPhone), and after telling him the phone was
|
||||
found in a ski resort his scam alerts went back green, and after him
|
||||
telling me the name of the ski resort, my confidence I found the real
|
||||
owner went green too.
|
||||
|
||||
Hopefully he was working not far away from my house, and we were able
|
||||
to meet literaly a few minutes later!
|
||||
|
||||
I asked him to unlock the phone as a last ultimate veritifcation he
|
||||
was the owner, which he was easily be able to do, then he showed me
|
||||
pictures taken right before loosing the phone! We had a nice chat
|
||||
afterwards, it's not a situation that happen often!
|
||||
|
||||
So next time you find a phone, don't give up, there's always a tiny
|
||||
lead hidden somewhere that could get you back to the owner.
|
||||
|
||||
I hope you all added some Emergency Information on your lock screen by
|
||||
now, saving me a lot of time if I find it!
