I want one of these flipper devices but I’m sure I would get in a lot of trouble with it

[–] [email protected] 27 points 2 years ago

If you cannot trust yourself, then do not provide yourself temptation

[–] [email protected] 14 points 2 years ago

Just call yourself a tinkerer or a person doing security testing.

If you're using it against other people, let them know.

If you use it only against your own devices, you'll be perfectly fine.

Which one: the Flipper Zero, or the bluetooth spamming function?

Flipper Zero is a thing because it's a very capable device for hackers and tinkerers. It can be used as an intro to coding and pen-testing.

The bluetooth spam is a thing because some dev is an asshole.

This is how we learn to make more secure software.

You don’t need a laptop to do that, there’s a WiFi Dev Board for the Flipper.

[–] [email protected] 6 points 2 years ago

Because it's cool and fun

[–] [email protected] 4 points 2 years ago

I saw one program that Rick rolled Bluetooth device lists.

[–] [email protected] 10 points 2 years ago

I wonder if I could get work to buy me one and claim that I'll use it for pen testing.

My coworkers would 100% definitely plug it in if they saw it lying around just to see what it was. They're real bad.

[–] [email protected] 5 points 2 years ago

More importantly, flipper Xtreme has a miku asset pack

[–] [email protected] 4 points 2 years ago* (last edited 2 years ago) (4 children)

You should probably keep your wifi and bluetooth set to switch off automatically anyway, what with how much they're used for tracking.

[–] [email protected] 23 points 2 years ago (1 children)

Doesn't work if you have Bluetooth devices on all the time (like a smartwatch or earbuds).

[–] [email protected] 1 points 2 years ago

Earbuds aren't on all the time, so you can enable when needed and set it to disable after a few min of activity.

I can see that smart watches might be a problem. They should perhaps use a dedicated protocol for always on devices like that.

[–] [email protected] 5 points 2 years ago

Tracking my HR and steps via smartwatch!

I don’t know if turning off Bluetooth protects against flipper attacks (Edit: Nah.), but unless something has changed, it (sadly) doesn’t preserve your privacy.

It’s not really documented, as far as I can tell, but Bluetooth low energy stays on, even when you toggle Bluetooth off for both iOS and Android. As of iOS 15, even turning off iPhones means the phone is still trackable. (Unsure about Android on that front.) Apple’s ‘Find my’ network uses Bluetooth low energy, same as Bluetooth beacons.

Confused developers: one, two, three.

[–] [email protected] 2 points 2 years ago (1 children)

That sounds like disabling Bluetooth on iphones doesn't disable Bluetooth LE. Sucks for iPhone users.

[–] [email protected] 2 points 2 years ago (1 children)

I mean, it sucks for everyone that can’t or don’t want to run homebrew OS’s.

The “One” link I shared above indicates the behavior became standard in Android 8 and iOS 11. They were released in August and September 2017, respectively.

[–] [email protected] 2 points 2 years ago

Yeah I'd like to think AOSP doesn't have that flaw.

[–] [email protected] 0 points 2 years ago (2 children)

Keep your BT off unless actively using it?

[–] [email protected] 7 points 2 years ago (1 children)

I almost always use it. For my smart band, PC notifications, wireless Android auto..

[–] [email protected] 2 points 2 years ago (1 children)

Well that's a security vulnerability tbh

[–] [email protected] 12 points 2 years ago (1 children)

Ok, well I'm not going to stop using my fitness band or Android auto because I'm a paranoid person. Might as well never leave your home and never use any devices connected to the internet.

[–] [email protected] -2 points 2 years ago (1 children)

Did somebody say you should?

[–] [email protected] 2 points 2 years ago (2 children)

DId somEbOdy SaY yOu sHouLd?

If you're not implying that, then your reply was pointless.

[–] [email protected] -2 points 2 years ago* (last edited 2 years ago) (1 children)

Show us on the doll where the bad comment hurt you, boy.

[–] [email protected] 2 points 2 years ago (1 children)

What was the point of your comment then if not a veiled suggestion to turn it off?

[–] [email protected] 2 points 2 years ago (1 children)

This is an online discussion forum, the point of the comment was to educate the public about the downsides of having BT on at all times. I am not sure why @Polar got some butthurt about basic info sharing. If this info not relevant, move on... why spazz? People who care will act upon this info as they deem necessary.

Also, conflating informational comment with a call for action is immature, at best.

[–] [email protected] 2 points 2 years ago

I didn't get butt hurt. I simply stated why I have Bluetooth on, and the devices I use require it, and knowing that information you told me it was a security concern.

Ok? And am I just supposed to sell my devices? Do you want me to turn my Bluetooth off so my device become useless? I don't understand the point of your comment.

Hey guys, eating can cause you to choke, it's a health concern. Better stop eating.

[–] [email protected] 5 points 2 years ago (2 children)

Looks like that’s an ineffective approach.

I commented elsewhere with an explanation and a bit of speculation. I did later confirm that even ‘disabling’ Bluetooth doesn’t stop the attack.

The attack method works even when Bluetooth has been disabled using airplane mode from the control panel, which may surprise you. In which case, you’ll be shocked to discover that disabling Bluetooth this way, erm, doesn’t. Instead, you’d need to disable it directly from your device settings or run your iPhone in Lockdown Mode to prevent these advertising pop-ups from being received.

Assuming similar on Android, it’s possible, but not that easy toggle everyone knows about.

[–] [email protected] 5 points 2 years ago* (last edited 2 years ago)

Correct both android and iOS don't disable it unless manually done in BT settings.

As you walk around your BT gets tagged and they sell your data.

Think of a setting like a mall ;)
