The instruction takes a easy type: it specifies which account to reassign and identifies the brand new proprietor.
When victims unknowingly approve transactions containing this instruction, they basically signal away management of their wallets.
The reassignment occurs quietly with out inflicting any token steadiness modifications, making detection extraordinarily tough for common customers.
