How the Scam Works

One or more scammers claiming to be Adam Back (Blockstream CEO) on Instagram are reaching out to users through Instagram direct messages.

What is being offered is unclear from reports. The scammer is chatting with their targets in both English and Spanish.

The goal of the impostors appears to be to obtain information such as users’ Blockstream Green wallet mnemonic backup so that they can steal users’ BTC funds.

The Real Adam Back

Dr Adam Back is an applied cryptographer and the cofounder and CEO of Blockstream, a Bitcoin infrastructure technology company.

Adam Back or any other Blockstream employee will never reach out to users to request mnemonic backups or other sensitive information.

Technology projects that Adam Back has been involved in can be found on his official website, and his official social media accounts include:

• • Twitter (@adam3us)
  • Facebook
