Friend.Tech Users Hit By Apparent SIM Swap Attack Lose Several Ether (ETH)

“The SIM swap attack on FriendTech users is a great reminder of the importance of strong security measures, especially for accounts containing valuable digital assets,” said Eran Karpen, Co-Founder and CTO at Unplugged, in a message to CoinDesk. “SMS, a technology developed in the 1980s, is relatively simple and vulnerable to attack. In the FriendTech case, the cell carriers were the attack vectors and were tricked into redirecting your phone number to a SIM card they controlled. Two-factor authentication (2FA) with an authenticator app, rather than SMS, authenticates on the device, not the cell carrier, and can mitigate the attack.”
