The official NEO Twitter page also reported the scam, seen below:
The scam website ‘neoblockchain3.com’, which has been blocked for users with the Nash extension installed, uses real information regarding the NEO 3.0 update but provides false token swap information and links to a phishing web wallet at the address ‘neoswap.org.’
Users that access this phished wallet are likely to have their private keys stolen and funds drained.
At this time, there is no official timeline or mechanism for the NEO 3.0 token swap. However, users will not be required to take any action until mid-2020 at the earliest. NEO will release official guidelines on any token swap process closer to the launch.
NEO users should always remain sceptical of any websites or applications that ask users to send their funds or share their private keys. Caution should be exercised whenever reading information that is not being shared via an official NEO channel, such as on neo.org and the official NEO twitter, or from NEO News Today.
