SIM Swapping & Identity Hijacking — Confidential Digital Investigation

You look down at your phone and see 'No Service' or 'Emergency Calls Only'. Within minutes, your email password is changed, your bank accounts are drained, and your cryptocurrency is gone.

You are the victim of a SIM Swap (SIM Hijacking) attack. In this terrifying scenario, the attacker hasn't hacked your physical phone; they have socially engineered or bribed your cellular carrier.

By transferring your phone number to a SIM card they control, the attacker instantly intercepts all your SMS-based Two-Factor Authentication (2FA) codes, granting them the master key to your digital life.

A SIM Swap is characterized by a very specific sequence of digital events.

The definitive signal is the sudden, inexplicable loss of cellular network connectivity on a device that previously had a strong signal, while Wi-Fi continues to work.

Simultaneously, the victim will receive a barrage of emails (if they can still access them) stating that passwords for critical accounts (Gmail, Coinbase, Bank of America) have been successfully reset.

Forensically, the device logs will show the exact millisecond the cellular radio lost registration with the network tower, correlating perfectly with the timeline of the unauthorized account access.

SIM Swapping is a highly targeted attack. It is rarely random. The attackers (often organized groups of young hackers) specifically target individuals known to hold significant cryptocurrency or valuable social media handles.

The attack begins with OSINT (Open Source Intelligence). The attacker gathers your name, address, date of birth, and phone number from public breaches.

They then contact your carrier (AT&T, T-Mobile, Verizon). Using the stolen PII, they convince the customer service rep that they are you, claiming they lost their phone and need the number ported to a new SIM card. Sometimes, corrupt carrier employees process the swap for a bribe.

Once the number ports, they trigger password resets on all your accounts. Since most services default to SMS recovery, the reset codes go straight to the attacker's phone, allowing them to seize control instantly.

A SIM swap investigation focuses heavily on proving carrier negligence and establishing the exact timeline of the breach.

First, we acquire the victim's mobile device and extract the baseband and cellular radio logs. This proves definitively that the device was forcibly disconnected from the network at a specific time, refuting any claims by the carrier that it was a 'glitch'.

Second, we issue preservation letters to the cellular carrier, demanding they lock down the internal logs showing exactly which employee authorized the SIM change, from what IP address, and what authentication methods (if any) were used.

We also analyze the compromised accounts, requesting login IPs and device fingerprints from Google, Apple, or the affected crypto exchanges to track the attacker's movements post-compromise.

The primary goal of our SIM swap forensics is to arm the victim with the technical proof required for civil litigation against the negligent cellular carrier.

We provide a comprehensive report detailing the timeline, the failure of the carrier's security protocols, and the direct correlation to the financial losses.

We also assist the client in migrating away from SMS-based 2FA entirely, implementing hardware security keys (YubiKeys) and Authenticator apps to ensure they can never be SIM swapped again.
