There have been reports on a new phone scam tactic whereby scammers will dupe victims into sharing their TAC (Transaction Authorization Code) number.

The modus operandi of this scam is as follows:

Modus operandi
  • The scammer/hacker will log in to your online banking account by a random password generation.
  • The victim will receive a TAC number SMS even though they did not perform any online transaction.
  • The scammer will contact the victim on the pretext of mistakenly registered the victim's mobile number for the online bank account.
  • The scammer will come up with all sorts of excuses/reasons to fool the victim into disclosing the TAC number.
  • Once the victim shares the TAC number, the scammer can transfer money from the victim's bank account.
What you should do?
  • Do not share your TAC number with anyone over the phone.
  • Ignore all persuasive attempts, even if they threaten you or appeal to your sympathies.
  • Change your online bank account password immediately.
  • If you receive TAC SMS without performing any online banking transaction, report to the bank immediately.
