US Secret Service issued alert warning of thieves abusing Informed Delivery for identity theft

  • The internal alert was sent on November 6th, 2018 to its law enforcement partners, stating that thieves are using the Informed Delivery feature ‘to identify and intercept mail, and to further their identity theft fraud schemes.’
  • Informed Delivery is a new offering from the US Postal Service (USPS) that lets residents view scanned images of incoming mail.

Krebs suggests that they could possibly be waiting until the cards are already approved and ordered before signing up for Informed Delivery in the victim’s name.



Fake banking app on Google Play Store used in SMiShing attacks

  • Trend Micro researchers discovered a fake banking app, Movil Secure, being used in a SMiShing campaign targeting Spanish-speaking users. The app, claiming to be a mobile token service, was first discovered on October 22nd, 2018 on the Google Play Store and registered more than 100 downloads over a six-day period.
  • Movil Secure associated itself with Banco Bilbao Vizcaya Argentaria (BBVA), a popular Spanish banking group. However, it was found to be a spyware, collecting SMS messages and phone numbers from infected devices and sending them to the threat actor’s C&C server. Furthermore, it hid itself from the victim by not displaying any icon on the user’s phone screen.
  • Through investigating the app’s developer, the researchers also identified three additional fake banking apps Evosecure, Bankia Secure and Compte de Credit.
