SIM Swap Crypto Theft: Account Takeover and the Law

One of the methods aimed at crypto asset holders is SIM swap (taking over a phone line by impersonation or cloning), which defeats SMS-based verification and gives access to accounts. The subject is covered below for information purposes.

⚖️ Legal Nature

Unlawfully taking over a person's phone line or account and removing their assets may, depending on each case, be treated as an information technology offence and as fraud.

In short: In a SIM swap, access to accounts is gained by defeating SMS-based verification; assets can be withdrawn this way.

🔍 Common Appearances

A phone line suddenly losing signal, verification codes going to someone else and notifications of unauthorised access to an account are common signs.

🛡️ For Victims

Victims may take part in the process through a criminal complaint and legal claims; operator records, transaction hashes and account access logs are important evidence. Blockchain tracingTR can contribute to the process.
