TCPC General Meeting

Two-factor authentication (2FA) /
SIM Swap Attack
Presenter: Jim Grotz

Are you required to use Two-factor authentication by your financial service providers including mutual funds, bank accounts, brokerage firms or retirement plan accounts? Be sure to attend this meeting to learn of the risks of using your cell phone for two-factor authentication. Possible solutions to this problem will also be discussed.

Two-factor authentication was touted as a means to provide an additional layer of security for your online accounts. The first “factor” is your usual account password that is standard for any online account. The second “factor” is a verification code usually retrieved from a user’s app on a mobile device.

A SIM swap attack / scam (also known as a port-out scam, SIM splitting, Smishing or SIMjacking according to Wikipedia) is a type of an account takeover fraud that targets a weakness in the 2FA process in which the second “factor” is a text message or call placed to a phone.

Jim Grotz will discuss, show supporting videos and offer suggestions on how to protect yourself. He will offer suggestions on how this crime could be deterred based on his experiences and seek input from viewers. The goal of this presentation is to make viewers aware of this fast growing cybercrime and to prevent this crime from happening to you.
