Summary

  • KrebsOnSecurity has authored an extensive report on the growing issue of voice phishing, and in particular the activities of a group of cyber criminals known as Crypto Chameleon, believed to be behind the recent theft of $4.7m from a cryptocurrency investor.
  • Crypto Chameleon is said to be behind the recent uptick in Multi-Factor Authentication bombing attacks targeting Apple users.
  • Multi-Factor Authentication bombing attacks typically involve a bad actor attempting to log in to a user’s account while the user is logged in, repeatedly bypassing authentication checks by repeatedly resetting the user’s password, thus repeatedly sending authentication prompts to the user.
  • Such attacks work unless the user notices the flurry of authentication prompts and intervenes.
  • In this most recent incident, Crypto Chameleon abused both Google and Apple’s voice services to trick the victim into thinking the fraudulent website purporting to be apple was legitimate.
