What is flasher_usdt_eth_btc?

This is a Windows tool that claims to modify the balance display inside cryptocurrency wallets on a local machine, making them show a custom USDT, BTC, ETH, or other token balance that does not reflect the actual on-chain holdings. The README describes it as a "client-side injector" that patches local storage, memory, or cached API responses inside the wallet software without connecting to any blockchain or accessing private keys. The tool targets browser extension wallets such as MetaMask and Trust Wallet by hooking into developer tools bridges or local storage. For desktop wallets like Electrum and Exodus it claims to use memory patching or library injection. For node-level clients such as Bitcoin Core or Geth it intercepts local RPC responses or cached files. In all cases the changes stay on the local machine and are described as reversible. A configuration file lets users set a target balance amount, choose a token network (ERC20, TRC20, or BEP20), and toggle whether the fake balance persists after the wallet restarts or disappears on exit. A separate option injects a fake transaction history alongside the spoofed balance. The tool ships as a single executable with no installation required and works offline. The project's own topics include terms like "fake-btc-transaction" and "flash-btc-software," and its stated purpose is to display balances that do not exist on any blockchain. Tools of this type are widely associated with cryptocurrency fraud, used to deceive counterparties in peer-to-peer trades or escrow arrangements into believing a payment was received when it was not. The README carries no security-research or testing disclaimer.
