Expert Explains How To Prevent Cell Phone SIM Card Swapping

[@pamcornelius9122]

There should be a class action lawsuit against the cell phone carriers who don’t verify ID before moving your phone number to a different device.

[@jvanek8512]

No. There are around 300+ million cell users in the US. The total number of sim swapping incidents since they've been tracking it is like 2000. By the time the sim swap happens the hackers already had hacked their email accounts and gathered a lot of data on them and some of it from social media

[@wownewstome6123]

The carriers do verify ID first, but the thieves have all they need to pose as you, such as using their phone to get past the "double-identification" process. This interviewee failed to emphasis how easily and quickly your bank account can be drained to zero.

[@mintoo2cool]

this was pretty ineffectual information about preventing sim-jacking

[@Back2SquareOne]

Yes. This video made some vague suggestions about how to limit the impact of SIM swapping but offered nothing to prevent it in the first place. The main way to prevent SIM swapping is to call your mobile provider and request a pin or password be associated with your account and required to be given before any changes to your account or SIM. This is not a great solution and is not always available but it is the best most providers offer. Unfortunately, most banks only provide 2FA via SMS (i.e. text msg). This means most online banking is potentially vulnerable to SIM swap attacks. Better methods of 2FA are available such as physical security keys and passkeys but banks have not adopted them. These kind of SIM swapping attacks usually happen overnight and by the time you discover the attack in the morning, the damage is done and your accounts are drained.

[@Tad-For-Global-Peace]

How about you use an email for 2fa that’s not on your phone, but you log in from a separate device, would that work? And maybe you can go to Settings, Screentime, Contrnt and Privacy Restrictions and make a pin and then not Allow change without the pin for 1. Account changes, 2. Password changes etc?

He said be careful what you put on a phone, what you keep on a phone and what you use the phone to access. That's pretty much what I do.

Yes they do. They offer to add specific secret questions like “When is my father’s birthday?”, “What is the name of my first pet?”, etc. Attackers cannot know answers to the questions; but to ensure your safety always flush the navigation history and “cookies” from your gadget before and after going to online banking: Ctrl+Shift+Del=>All time=>Clear data.

[@soulshine8531]

I’m now listening to everything about this.. so it’s starts with the phone service by not getting identification.

[@shaggydawg5419]

jvanek8512 is correct. It starts with an ID theft. Remember scammers need your info to convince your cellular provider they are you. The more the know about you, the better their chance succeeding in the attack.

This is why you don't use your phone number for any type authentication. Everything goes to my email, which needs a password to access. It really isn't difficult people. Stop using your phone for everything.

[@AustinHollingerOfficial]

if you properly secure your email with app based two factor authentication, email is obviously the better solution

[@SK-hs4fp]

Amazing - the title is about how to prevent sim swapping. And the conclusion is that it cannot be prevented and therefore you take other measures to protect your accounts - such as multi-factor authentication - when the only multi-factor authentication that 99.99 percent of the banks provide is via your phone number (sim). Great click bait title!

[@erintyres3609]

I went through all of my accounts recently to set the best available security. I found that I could use a FIDO2 security key for some accounts, authentication apps for some accounts, email authentication for some accounts, SMS text message authentication for some accounts, and no multi factor authentication at all for some accounts. Don't use your phone for banking and investing.

[@bassmaiasa1312]

At least it helps to be aware of it. E.g., I will never use any website (TikTok, e.g.) that requires me to give them my phone number. Also, banking is the biggest but not the only risk. If a crook hacks your social media or secondary account, they can use that info to impersonate you. E.g, I called up an old school friend's mother from his yearbook home number "Hi! I'm a friend of Johnny, I was on the tennis team with him at Rutgers. I'm trying to get in touch with him." "Oh isn't that nice. Here, let me get you Johnny's new number."

[@HereForToday42]

most cell phones now have a setting where you can lock your account. AT&T has it now- I went onto the AT&T app into my account, and you "lock account". Nobody can swap or change anything without you authorizing it

[@roachtoasties]

The expert didn't mention to call your cellular provider and ask for enhanced security. Require a PIN known only to you for any account changes, including a port pin. While there's no guarantee nothing will happen, as employees at the cellular company could taken by a scammer, every little bit helps. Also, the expert said SIM stands for subject identity module. It's actually subscriber identity module. Anyway, stealing one's phone number has to deal with fooling someone that they are you, and you need your phone number moved (you lost your phone, and so on). The SIM or eSIM is just the underlying technology.

[@meblake7359]

There is nothing out there known only to you if you even said it.

[@knotox]

100% of SIM swap attacks are the result of someone other than the owner of the account modifying the account without the owner's approval. A company called Cloaked Wireless has solved this by only letting the subscriber modify the account (their staff can't modify accounts). Basically, it solved the whole SIM swap problem.

[@SK-hs4fp]

The Indian government has done something about this issue. It isn't perfect but it's at least something and I don't understand why the US cannot do the same thing. In India, no matter who the carrier is, if you swap your SIM (even legitimately), SMS text messages will not work for 24 hours on the new SIM. That's by law. This 24 hour period might give enough time for the real owner of the number to figure out that something is wrong because their phone stopped working and do something about it. Anybody who steals your number with a new SIM will not be able to receive OTPs etc for 24 hours.

[@josepeixoto3384]

An absolutely great idea...

[@martinalbert29]

I did not link any bank accounts or credit cards or anything with 2 factor authentication to my SIM card/phone because of things like this. I’m old school and do everything over the counter at the bank. So if they get my sim they get nothing.

[@AB-cb4qw]

I agree. Many people are doing this. It's safest way. I also prefer cash,as I know what I have or haven't got!! :-)

[@ace942]

Actually you should set up a PIN number with the carrier itself. A person requesting any changes to a phone number would need to provide the carrier with the PIN number that you created with the carrier. If they can not provide the PIN number, the carrier should not make any changes to the account.

[@mrtechie6810]

If your providers still use simple 2-factor authentication (e.g. SMS, last 4 digits of payment, mother's maiden name...) to reset passwords, please file a complaint!!! Banks and cell providers should use proper multi-factor authentication like authenticator app, security key, and unique backup codes!

[@gerrybuffett770]

There are times when SIM swapping is needed, such as if you drop your phone in the lake, or you lose possession of your phone.

[@3204clivesinclair]

Using txt messages as an authentication method is so dumb.

[@imjamming]

SIM swapping/cloning is another form of identity theft. If someone was to swap my SIM card, it's not going to be very beneficial to that person because I don't use my phone for financial transactions. I keep very little personal info on my phone. I don't immediately answer calls from unknown numbers so I will not be caught off guard. I don't reply to just any text messages either. I don't use my phone to access online services either.

[@jashannon]

With the newer/higher end phones it's optional use a SIM - they have an "eSIM" which is builtin to the phones. I know iPhone 13 as one example I have personally helped someone switch to. Just call tech support with your cell provider and tell them you want to use only the eSIM. Then break the SIM with plyers, throw it away, and you're safe from this scam no matter what. Or Google on how to add the SIM pin if you don't have one. (The default pin is 0000 with Androids apparently, which is needed to set your pin.)

[@Sashazur]

Why do you think eSIMs are more secure? I’m not a secure expert, but I’ve used both kinds, and in my experience I don’t think that eSIMs are more secure or more immune to this scam compared to physical SIM cards. In fact they may be worse since the thief doesn’t even need to go anywhere to get one, or wait for it to be shipped to them. Once they convince the phone company that your number is theirs, they can download and install the eSIM in minutes no matter where they are.

[@bassmaiasa1312]

How does an eSim prevent a crook from calling up and saying they need to switch your number to a new phone?

banks don't let you bypass the texting method of multi factor ID. Bio data is still a file that gets compromised - it's a saved file that gets matched in authentication - so it can be stolen as well. Photos can be used for face verification - it's not hard. with the number of 'new' cellphones that were actually 'returned' phones being sold as new BY the wireless carriers themselves - would certain exploit the ID of customers. Removable sim cards are being discontinued in the US - so you can't just switch them out to overcome this issue yourself/autonomously.
