I just have one question about this sim port attack. In order for anyone to hijack my SIM, he needs to be present in my local area and it can't be done outside the country. Is it so?

For example, In my country, we have JAZZ, WARID, and Ufone mobile operators and since these networks are available locally, it is not possible for anyone to port my sim internationally and get the codes/SMS etc. ?

The attacker would need to have assistance from someone who has the ability to update your mobile phone account with a new SIM card. This means the attacker can be in any location. Some mobile phone operators have employees based in other countries than where they operate.

If I may just bump this thread,

https://www.bleepingcomputer.com/news/security/scammers-drain-bank-accounts-using-anydesk-and-sim-swapping/

Quote

Scammers mixed together a malicious cocktail of social engineering, SIM-swapping, and remote desktop software to empty the bank accounts of at least three victims.

In total, victims lost more than $350,000. They were likely swindled by the same individuals since the modus operandi and some details were the same in all three cases.

In at least one instance, the scammers converted the money to cryptocurrency, to make it more difficult to track.

Dangerous combination, social engineering + SIM Swap = lost of money to the victims.

SIM port attack turns out to be a very-simple-money even for teens. IMO, to prevent this carrier providers should at least temporally charge for the swap (say $1000) and refund it after SIM original owner confirmed it. If not then that swap should be canceled and money not be returned.

For sure that is already have been thinking or tried by some telecommunication providers, but they should also think some of the parts where their customers will easy to swap their sim cards in a legit way, that's why this Sim Port Attack is started to spread.
For me, the best way to do is actual sim swapping per customers, like the customer is allowed to go in some branch or office of their telco, but this is kinda not comfortable for the side of the customer.

yes, i worked with a telecommunication company 2 years back. there were issues like this and it is a frequent re-occurrence. scammers do connived with bank staffs to swap sim cards of rich persons. after which they(scammers) contact the telecommunication for sim swap. such occurrence which requires a proper check up by the telecommunications due get outsmarted after series of check by the telecommunication.

Today I read another news related with SIM attack, Called WIB (Wireless Internet Browser) attack.

This is explanation about WIBAttack

Copyrights: Ginnoslab.org

Quote from: ginnoslab.org pages

What is WIB?

As an alternative to static SIM toolkit applications with a fixed pre-installed menu, some operators opt for dynamic SIM toolkit, where the menus and user dialogs are generated on the fly based on information provided by a central server. SIM applications that provide this functionality are generally referred to as SIM-browsers or µ-browsers.

Two browsers are currently available, the Wireless Internet Browser (WIB) which was the first successful browser released and promoted on the market by SmartTrust.

The Wireless Internet Browser (WIB) is specified by SmartTrust and is the market leading solution for SIM toolkit based browsing. The WIB-enabled SIM has a menu stored on the SIM. This menu can be managed and updated using Over The Air (OTA) services.

I found an article about cases on sim port attack, but this article was on June 2019. But it is said that most of the victims or almost compromised are into cryptocurrency, check here: Wave of SIM swapping attacks hit US cryptocurrency users.
And it was stated by one of the detective about this case, possible 3 ways:

Quote

The first is when the attacker bribes or blackmails a mobile store employee into assisting in the crime. The second involves current and/or former mobile store employees who knowingly abuse their access to customer data and the mobile company's network. Finally, crooked store employees may trick unwitting associates at other stores into swapping a target's existing SIM card with a new one.

Twitter CEO Jack Dorsey recently has his twitter account hacked via what appears to be a SIM port attack in which someone was able to send many racist tweets on his behalf.

The above is the only details released by Twitter, and it is possible there is more to the story. This does show that anyone can be a victim of these types of attacks.

I was about to post this info as well but you beat me to it. Anyways, you are right even the CEO of Twitter was hack and it could be this method as well so no one is really safe from this online criminals.

Quote

How did it happen?

A source at the company confirmed to the BBC that the hackers had used a technique known as "simswapping" (or "simjacking") in order to control Mr Dorsey's account.

https://www.bbc.com/news/technology-49532244

The hacker apparently was able to tweet via sending text messages from the number in question, making compromising the number the only thing needed to access the twitter account.

In theory, hackers might be able to spoof the number text messages are from in order to send tweets, which might make SIM porting the number unnecessary.

Twitter temporarily disables 'Tweeting via SMS' after CEO gets hacked

Quote

Twitter today finally decided to temporarily disable a feature, called 'Tweeting via SMS,' after it was abused by a hacking group to compromise Twitter CEO Jack Dorsey last week and sent a series of racist and offensive tweets to Dorsey's followers.
Dorsey's Twitter account was compromised last week when a hacker group calling itself "Chuckling Squad" replicated a mobile phone number associated with the CEO account and abused this particular feature to post racist, offensive messages and bomb threats from it via SMS.

https://thehackernews.com/2019/09/tweet-via-sms-text-message-hacking.html

So it looks like they temporarily 'Tweeting via SMS", disable it after the Dorsey fiasco. Seems the least they can do right now to prevent such exploit in the future.

Twitter previously said they had kept the feature available because some parts of the word have very expensive internet/data and twitter wanted to keep the availability of tweeting to as wide of population as possible.

At a minimum, Twitter should reply to SMS tweets with a request to enter a password, but ideally, someone would need to send a time based code that is good for perhaps several minutes to an hour each time they want to SMS tweet.

Not your keys, not your coins!

I have not noticed the feature to tweet via SMS. I always log in my Twitter account, and honestly I simply read others' tweets. In my nation, there is very limited proportion of Tweeters, so I join Twitter mainly because powerful guys prefer to use Twitter to spread their important news, perspectives, analyses, etc. fastly.

The hack demonstrates that activate 2FA security for accounts is important, not only with Twitter, but also with Facebook, Instagram, exchanges, casinos.

I have recently removed my mobile number from accounts like gmail, because of the risk that sim swap can be executed against me. It's a weird case when a security measure can make you less secure, instead of at least being just useless. I just can't trust that greedy mobile operators from my country won't sell my number to hackers for a bribe, or hire staff competent enough to recognize hacker's attempts to hijack a number.

And then they say that it's crypto where people lose their money. I'm sure most people here will be blaming crypto alone without even understanding that in this case, the subsistence of services provided by these carriers is to be blamed because their system itself comes under the fault as they allow people to swap their Sim cards with minimum info needed. I can understand that their major concern is to give their customers with quick resolutions but this is where they compromise with their security as well. This incident shows that nothing should be trusted (even your phone number). The person who lost $100k shouldn't have used phone or SMS verification in 2fa at the first place, they must have gone for Google's 2fa).

Tips to avoid this

Avoid storing your coins or funds for long term in a centralized exchange.
Avoid using centralized cryptocurrency wallet.
User hardware wallet or cold wallet.

Aside of this complicated kind of attack, these are in general pretty basic rules of crypto security.
Storing on centralized exchange is biggest mistakes people can make in crypto world.
I would add to that list also paper wallet as cheaper (free) way of storing crypto. Hardware wallets cost from $20-$100.[/list]

Just some update here:

Quote

The unscrupulous operators of the TrickBot trojan -- one of today's most active and widespread malware strains -- are now capable of carrying out SIM swapping attacks, security researchers from Secureworks have told ZDNet today.

This is possible because over the past month, TrickBot operators have developed a new version of the malware that can intercept login credentials and PIN codes for Sprint, T-Mobile, and Verizon Wireless web accounts.

The data TrickBot collects can allow its operators to carry out a so-called SIM swapping attack, porting a victim's phone number to a SIM card under their control.

This would allow the TrickBot gang (or someone else) to bypass SMS-based multi-factor authentication solutions and reset passwords for a victim's bank accounts, email accounts, or cryptocurrency exchange portals.

Really scary how these cyber criminals are evolving.

Sim swaps in my country happens very often, because there are criminal syndicates working within the mobile network providers that are doing these illegal Sim swaps. I also know about incidents where employees were blackmailed to help these criminals to swap some of these Sim cards. Angry

A friend of mine had his whole Bank account swept, because someone within the Bank, worked with these syndicates to hijack his mobile phone and to clone his ATM card. Angry

I avoided downloading files online using my phone to prevent from getting hack, but hackers now are getting smarter.

This attack has nothing to do with malware or downloading software. It is a social engineering attack that tricks your cell phone carrier into transferring your service to another phone so the attacker can receive your text messages.

Yeah I understand, thanks for clarifying it.

So this is riskier than downloading files in the internet, this one, even if you are online, you can still be victim of hack.
As I have stated, what I only avoid is downloading files online but don't know it's still possible to get hack with the new way of hack shared by OP.

You can avoid the effects of this attack by not using your phone number (receiving a phone call or SMS message) as a means to unlock any financial account. Not as a second factor, and not as a means to reset your password.
