Burner Phone & IMEI/IMSI op$ec

IMEI and IMSI are unique numbers created by cell phone manufacturers and operators. The IMEI number is directly tied to the phone and is tracked by operators and manufacturers. Every network connection you make in your daily life is recorded, and many apps use it in the background to verify your identity.  You're not aware of it, yes -).  As for IMSI, it's directly tied to your mobile subscription. It's encoded on your SIM card and cannot be changed. It's associated with your phone number linked to your SIM card.

Foolish agents affiliated with the FBI often track you using operator records (base station logs), manufacturer sales records of the Q-brand phone you use, SIM card records, and IMSI catchers. A professional hacker is often not deciphered by their IP address. You should separate your real life and your virtual life into two distinct parts.

I will also touch upon some important points on a few topics:

/$ Manufacturers keep sales records. They record Wi-Fi access points and MAC addresses.
/$ When choosing a burner phone, you should choose a simple, old model.
/$ Your phone's battery must be removable.
/$ You should choose a model without Wi-Fi.
/$ The phone you use in your real life should never be with you; choose locations without cameras. You should pay with cash. Do not share any personal information.
/$ You should learn to use a Faraday bag and make it a habit.

IMEI: Every time your phone connects to a mobile network, it registers the IMEI along with the IMSI.  It is used by banking apps and smartphone operating systems (Android/iOS) that abuse phone permissions on Android to identify the device.  It is possible to change a phone's IMEI information. However, it is easy to find and buy an old, working phone with the features I mentioned above. You should pay with ca$h.

IMSI: This is directly related to the mobile subscription or prepaid plan you use. It's linked to your phone number by your mobile provider. And remember, every time your phone connects to a mobile network, the IMSI number is also registered on the network along with the IMEI. Like IMEI, IMSI can also be used by applications to verify your identity. Foolish agents like the FBI have an IMEI/IMSI query database.

How are you tracked using IMEI and IMSI?
i) Mobile Operator Subscriber Records: Mobile operators store IMEI and IMSI information in their databases. Do not use both an anonymous SIM card and your real SIM card in the same cell phone. This is because IMSI/IMEI records are compared.  Since your operator has the ID information for your real SIM card, it will be very easy for them to identify you.

ii) Mobile Cell Tower Records: Operator cell tower records log which IMEI connected to which towers.  IMSI, on the other hand, keeps your connection data.  They record that a specific IMEI/IMSI combination connected to specific mobile towers and the signal strength reaching each tower. They can easily process this signaling graphically and narrow down your geographic location. And at the same time, they know your real phone that is connected to the same towers. For this reason, your real phone and the phone you use for illegal activities should not be.

iii) Your Phone's Manufacturer: The manufacturer can track the sale of the phone via its IMEI. Unless you bought the phone from a flea market, they can determine who the phone was sold to, including the serial number/IMEI information, and from which manufacturer-affiliated dealer at which location it was purchased. I told you never to have your real phone with you when buying a phone from a flea market because, even if you pay cash for the burner phone, if your real phone is with you, they can identify who was at that location through signals, tracing it back to you.

iiii) Use of IMSI: With IMSI, they can easily identify you and reveal your identity. Nowadays, you have to provide your identification when buying a SIM card. If you want to own a SIM card physically, it must be registered under someone else's name and not linked to your identity.

iiiii) IMEI Correlation Attack: If someone uses a fake phone, for example, and this phone occasionally connects to the network, while the person's real phone is also turned off at the same time, this makes it easier for an agent observing the connections behind the devices. Thus, by establishing a connection between these two phones, they can determine which phone belongs to whom. You might get caught in an operation one night without understanding what happened.

Agents who want to investigate your phone number actively use IMSI catchers like Stingray. Stingray mimics a cell phone tower, effectively performing spoofing. In this way, if the IMSI is determined, it forces your phone to connect to the simulated tower. If they succeed, they can easily listen to your phone, examine your data traffic, and clone your phone number without needing your phone.

Due to these risky situations, it is important to use a phone that is not connected to you and purchased with cash when carrying out illegal activities. A physical SIM card is risky, but if you can manage yourself, it is highly secure. You can buy a number using cryptocurrencies like Monero, which are impossible to trace when proper techniques are applied. We will be discussing this today!

Your Wi-Fi or Ethernet MAC Address:
A MAC address is a unique identifier tied to a physical network interface. If you don't randomize it, it can be used to track you. I can almost hear you saying no -). As I mentioned in the IMEI example, computer and network card manufacturers always keep sales records. This information also includes the MAC address.  With the MAC information, they know when and to whom your computer was sold. You don't want this. You should not use Bluetooth-enabled devices, such as headphones, as they also store and save MAC address information.

I'd also like to write something about the risks associated with smartphones. We need to talk about things you shouldn't forget when conducting illegal activities. Never carry your real smartphone with you. [Even if your device is turned off.] Various correlation attacks are carried out on cellular networks to detect your turned-off phone and the activated burner phone. Make sure to set up your smartphone, which you leave at home, to appear active and leave it that way. For example, you can leave it as if you are watching a movie. This way, you make it more difficult to detect your digital traces.

However, if one day you need to carry your real phone with you, you can turn it off, remove the battery, and put it in a Faraday bag. If you want to be a true op$ec, you have to do everything manually yourself. There should be no 3rd party involvement.  I'm explaining most of the information I've written so far incompletely; remember never to explain anything fully. You don't want to expose yourself; you can develop and use this information by spending time on it yourself.

You will need an anonymous SIM card and an anonymous phone here, which I will also explain to you. Go to a flea market and only carry cash. The place you go to should be a place with few or no cameras. Buy a working cell phone like the one I described and leave. If possible, you can buy a Nokia phone. Using the 3G feature prevents the phone from sending any telemetry data. Do not turn on this phone you bought in any geographic location, even without a SIM card!  That is, it should never be associated with your real phone.

Let's briefly touch on activating and topping up a prepaid SIM card. If you can use GiffGaff, I recommend using it because it does not require ID for activation and top-up, and you can change your number online. After completing the activation/top-up process, turn off the phone and do not turn it on before you get home.

Finally, I will mention a few things about getting an online phone number. If you decide to do this, you should have prepared your op$ec very well. I can't imagine otherwise -).  You can try using the Iceland-based site [crypton.sh], which accepts XMR and does not require any verification. Remember, it's always a risky situation. Use/don't use it by scaling the risk you're in.
