SatoshiLabs disclosed that it is suspected to be a sophisticated and premeditated phishing attack planned by hackers over several weeks.
SatoshiLabs, the company behind Trezor X, has issued a detailed explanation of an incident that led to the posting of fraudulent presale token announcements on its official X account.
The company said it was a phishing attack that caused the security breach and not a SIM swap attack, which was suspected at the time.
SatoshiLabs emphasized that they do not use SMS for two-factor authentication (2FA), opting for more secure authentication methods.
