A hacker stole and minted tokens in attacks on Fetch.ai, NuNet, and SingularityNET, generating about $2.25 million in realized profits. According to NS3.AI, Bitquery said the nominal value of the minted tokens was several times higher, while PeckShield estimated the attacker’s unrealized profits at almost $17 million.

The attacks involved 16 wallets and a payroll contract. A report also warned that most signing keys had not been changed.
