The following are indicators of a SIM swap attack: 

• Sudden unexpected loss of mobile signal, for you only. Other nearby mobile users are unaffected. This results in the inability to make mobile calls and text messaging to and from your phone.
• Notification from your mobile provider that your SIM card or phone number has been activated or migrated, without prior knowledge or agreement.
• Inability to access online accounts. This could include bank and credit card accounts, email and social media.
• Fraudulent bank and bitcoin transactions to unknown 3rd parties.
• Unexpected social media activity and posts.
• Sudden increase in phone calls or texts. This can be carried out as a distraction technique prior to the swap. It forces you to reset your mobile device providing the attacker the opportunity to carry out a SIM swap attempt.

Dealing with a SIM Swap incident can be difficult because by the time you are aware, the swap may have already taken place.

1. Act quickly – As soon as you suspect something is wrong - act. The longer it takes to react, the potential for more impacting activity by the attacker is possible.
2. Contact your Mobile provider – explain the situation and ensure the provider commences investigating the incident and recover your account back to your control and investigate how the swap occurred.
3. Contact your financial organisations immediately – Advise your banks of the incident and review any unexpected transactions or access issues with them. Request a reference number for your call to them.
4. Keep a log of your actions - note who you have contacted, when, what actions were agreed to be completed and when by. Mistakes can be made so record your actions in case of future disputes.
5. Repeat point 2 and 3 – be sure that the incident you have raised has been correctly recorded and action is being taken – call them back and check.
