What happened

Attackers collect enough personal information to convince a telecom channel to replace or port the victim's SIM.

How it works

After gaining the line, they receive SMS OTPs, reset passwords, and attempt transfers before the victim notices.

Red flags

  • Your SIM shows no service while others nearby are connected.
  • Password reset or login alerts arrive from financial apps.
  • Contacts report strange requests from your accounts.

What to do now

Contact the mobile network fraud desk and bank immediately. Ask for a SIM lock, block affected accounts, and move critical logins to app-based authentication.

What not to do

Do not wait for service to return on its own if financial accounts are tied to the line.

Evidence notes

  • Network service timestamps and bank alerts help reconstruct the takeover window.
